2000 to 2007 GM Truck 4.8, 5.3 and 6.0 Engines. Weird Rattle On Acceleration
Vložit
- čas přidán 7. 05. 2021
- This video will likely apply to all GM trucks with the 4.8, 5.3 or 6.0 litre engines from 2000 to 2007 and possibly others. The truck has an erratic tinny rattle noticed more with the windows open on acceleration going forward or braking in reverse. The problem is a broken starter drive shift fork which allows the starter drive to slide into the rotating flywheel teeth.

You're a life saver! I could not find any videos that replicated this sound. I have a 1995 GMC C1500 that currently has this issue, but only under hard acceleration. Goes away if I restart the truck (which led me to believe it was the starter in the first place). Thanks for helping me confirm!
Glad it helped you out
I have a 2005 Jimmy and I hear that noise. I get a grinding feel and sound like that. Im gonna pull the starter and see if its busted or teeth wear
Darn it old boy!! You just taught this old dog a new trick!! Your the BEST!!!!!!!!!!!!! Thanks for your hard work to bring us all the videos!!
I have a 2011 Silverado started having this problem and I came across your video. It was all the same problems Thank you so much for this video. It helped me out a lot. And problem solved.
Just got my 2013 Tahoe Z71 and I started hearing this sound.... Was driving me crazy cause like i said i just got the truck and been researching for weeks and this is exactly what my truck does.... Thanks man
Thanks for the video! I searched high and low for this issue I was having on my 2011 Silverado, this was it!! Mine would also make this noise while idling, just a note for other viewers.
Thankyou! Years of experience show in your work!
Your video helped me identify my noise and repair. I replaced starter today in my 2023 Denali and you were spot on! Thank you!
Glad it helped you. Seems pretty common.
Same
Thank you for posting this it was very helpful in figuring out what the hell was going on with my 2009 chevy! I was lost as a week end worrier and was waiting for the motor to break down! Exactly same thing and was making same noise! New starter and fixed the problem! You rock!
Glad it helped you was definitely a head scratcher at first...
Thank you for taking the time to post this. I would have never thought the starter was causing this noise on my 09. You saved me many hours of stress and searching to find the cause.
Definitely was an odd noise but appears to be quite common. Glad it helped you out.
@@PhillipBailey question??? My 05 sierra 1500 5.3 makes this same sounding rattling for a few seconds at start up and lightly reving the engine it starts to do it a little lighter sounding starting at about 1800 rpms but don't really here it past about 2500 rpm. I thought I was hearing the timing chain but after your video lol I'm hoping it's just the starter motor. Whats your thoughts ? Greatly appreciated the video.
@@brentacusmaximus6677 if you can reproduce the noise sitting still possibly with someone in the cab stepping on the accelerator then use a stethescopebto try to pinpoint the source. Could be drive belt related. The tensioner on at AC belt tends to fail and rattle. Take the belt off and try it. Good luck.
@phillipbailey my 2012 is making a tick like noise coming from the bell housing on the right side where the starter is that’s where u can hear the noise from the loudest I had a 6l80 swap done an had to go back for a upgraded torque converter. Well I got it back now runs and shifts fine but this noise is driving me crazy
Same symptoms on 2002 5.3.. I suspected the starter, but hearing all symptoms you described, now I have no doubt.. thanks for sharing
Got an old chev c/k 2500, having the exact same clicking noise dead on. Thanks for helping me diagnose this 👍
You nailed the problem on my 2008 Sierra. Same tink tink noise on acceleration and inclination. It was driving me insane trying to find the problem, so thanks for the idea and the work!
Glad it helped you out.
Dude, awesome thank you so much. I just changed my starter out this morning and sure enough the exact same issue was causing the pinging
attling noise. There's not lot of videos on here that show this, most pinging
attling noise videos are for lifters or rods or fuel injectors making noise. Thanks again.
Glad it helped you.
Thank you so much this is exactly what I have been looking for
After 3-4 months of worrying about that clickety click noise being the torque converter, cracked flywheel, transmission- I found this video and changed the starter in my 2015 2500hd with 6.0 gas and the problem was EXACTLY the same so THANK YOU Phillip!!
Glad it helped you out.
Have been having mine do this on 2012 Silverado and thought starter a couple of weeks ago but it sounded like in the oil pan. Googled it and you’re video popped up with the same exact noise mine has been making. Thanks for the help with this video!
Glad it helped you.
Was chasing the same sound on my 07 sierra for days after a motor swap kept thinking it was something motor related or broken flex plate finally came across your video and sure enough my starter is the same way thanks for the help
Glad it helped you.
This is exactly what's happening on my 2013 Silverado! Thank you so much for helping me figure this out.
Glad it helped you out
PHILLIPS, good information and enjoyable as always brother thanks for sharing.
The same problem with my Ram 1500 Hemi. It's been weighing heavy on my shoulders for about a month. All of my research suggested the flexplate was cracked and I was anticipating spending a few grand to have it replaced. Finally, I came across this video and found a solution. Thank you for sharing your time and knowledge. I hope to buy you a beer some day!
That's interesting that a Ram could have the same problem but certainly is possible. Did you actually fix it already?
@@PhillipBailey I sure did, I saw the video this morning, ran the same tests in your video with the same results. I pulled the starter and it had the same wobbly pinion. I put a new one in tonight and it’s sounds great now!
@orchardsofsteel8912 good to know. How did you stumble across my video driving a Ram?
Appreciate it, Had this happened to me this past Saturday. Finally got the part and changed it today. Problem resolved 👍🏻 Thanks
Glad it helped you.
Thanks man, this noise has been driving me nuts for the past 2 months
Glad it helped you out
Fantastic video! The sound was dead on to the sound my 02 Avalanche was making saved me a ton of time!
Glad it helped you out!
Thank you for the “sound samples” and un/install tips. My 2013 Silverado 1500 Lt had only 108k miles and started that same click at idle and driving last week. Switched it out tonight. The new starter sound caught me off guard for a second. Now I can worry about all the other noises and clicks! Lol. Thanks again!
Scott. How much did the repair cost? Mine was $425 at mechanic shop.
@@scottthomas3634 , just the price of a starter that I replaced myself.
Yours did it at idle? Mine is making a very similar noise but i was told it was a rod bearing, im only 20 and my truck is under payments, idk what to do.
Have it checked by another mechanic. Rod bearing knock is very bad and usually much louder and deeper. How long have you been driving it like that? How's the oil quality, level and pressure. Check for suspended silvery partials in the oil.
@@toxicjoker1533 , it clicked intermittently not consistently. Mine sounded like the video when driving. At idle and not moving it would click a little and then go away and then come back again. The starter gear was just moving back and forth. When I pulled the bad starter it did the same thing as in the video.
I’ve had the exact same symptoms for the last week . to be honest I was looking at new engines I thought it could be an internal bearing .. I’m ordering a starter tonight and going to see if it goes away .. thank you for posting this much appreciated !!!!
Let us know if that fixes the issue
@@PhillipBailey she’s fixed.!! that was definitely the issue. Thanks again for making this video man you rock
Bro I have been trying to figure out for so long thank you bro
That is neat how you figured that out.
That being inclined made the sound, and doing nothing else to make it do it.
Mine is making the same noise right now. My first guess was the starter Bendix engaging the flywheel. Thanks for this vid to confirm my suspicions
Dude this video just saved me so much time and money. Thank you 🙏
Glad it helped you!
MY SAVIOR... I've spent several months (10 ) to be exact trying to figure out this noise. THANK-YOU SO MUCH 👍🏻
I owe you bigtime..NO matter the cost,size or trouble.
Glad it helped you out.
He’s my Savior too. I pray to him every day.
Thank you, I have been searching on CZcams for weeks to try to diagnose that exact sound. I’m going to check to see if I have the same issue. I have a 2005 Pontiac G6 that makes that identical noise when turning left and accelerating. The starter is mounted sideways I believe on that car. Thank you again. I’ve replaced both CV axles, wheel bearings, struts etc.
Yes the starter is mounted sideways so it would be susceptible to yaw forces turning. I would think though it would be worse turning right. Good luck.
This was the exact cause of the issue on my 2005 Suburban 5.3. Your t-shoot steps and description helped a lot. Excellent work!
Glad it helped you
Same on my 2010! Fixed it with new starter! Thank you so much! Noise was embarrassing
Glad it helped you.
This is not just restricted to the vehicle years you have mentioned, I have a 2011 GMC Savana van with a 5.3 and had this exact noise driving me crazy until I saw a similar video, I removed and replaced the starter and that was the exact problem! The drive was lazy and rattling against the flexplate, at one point I was ready to separate the transmission and remove the flexplate so I'm glad I found this to be the issue!
Yes based on the comments it appears to affect a lot of years and models. Glad you fixed it before pulling the transmission.
I removed and replaced the fly wheel trying to solve this issue. This is what I should have done.
just exactly same 3 observations I got, and I thought about the same issue about the starter, I bought a brand new one $200 lifetimeW, when going under the truck and hearing again, I doubt again it was the starter, fiuuu! I was close to return the new one, and looking for some other faulty part, but your video has saved me wasting time and more money. I have Silverado 2011 5.3 Mex. 4x4, Thanks a Lot. I will proceed to change it.
You will know when you get it out if the starter drive just falls out.
I would pay money to watch your videos
Thanks so much for this VIDEO!! TURNED OUT TO BE MY EXACT PROBLEM. I CHANGED THE STARTER, PROBLEM SOVLED!!! 2013 GMC YUKON👌👌
Glad it helped you.
2 years I finally found the exact noise that matched my 2007 Gmc yukon🙌 thanks
Glad I could help!
What exactly did you order?? I have 07 Tahoe.
@@ManMan-Real Bought a new starter
Yeah it wouldn’t pop up but found an acdelco on rock auto. Thanks!
Thank you! I was going insane by this sound. I thought somebody left a socket in bell housing :D I could also hear it very loud when put front up on jacks, and not hear at all of rear higher.
Glad it helped you out.
Going to have to try this on my 07 Tahoe. Fingers crossed 🤞
Spot on. Found mine same way. It sounds like a heat shield ting. 👍👍👍
Dude omg thank you for this video
Thank you! I just bought a silverado and it was driving me crazy! It was the starter smh Thanks!
Life saver! Thank you
I was looking at rattle noise videos and this one sounds just like my tahoes problem tried it in reverse also no rattle going to take starter off and check it out thank you so much new subscriber
Let me know if that's your problem.
@@PhillipBailey did your issue get resolved after new starter?
@@latiajuana2953 yes that was the problem on this truck.
I've replaced multiple starters for this reason on GM trucks with the LS engines, but never/yet on GM cars or CUV's. I wonder why?
You are the man. I have had this same problem. I thought it was a cracked flex plate or loose bolt in tranny. I was scared i needed a full tranny rebuild. My noise only happens when first put into gear and going slow under 3k rpms. Maybe wjen it gets faster its drowned out by road noise. But thanks so much for posting this video.
You just took my oh-sh!t-o-meter down about 50% thank you.
My 2004 Chevy started a little chatter. Took the starter out and the pinion drive was doing the exact same thing. Changed starter and noise went away. It never made any other noise and started fine lol. I would not have thought it would of been starting it still.
Glad you figured it out
Thanks for this video
My 05 2500hd has been doing this for about a month and started after I had pulled a large boat. I was thinking it was something with the transfer case or possibly the transmission. I’ll pull the starter to confirm it is the issue. Mine mainly does this when I am moving forward and it shifts from 1st to 2nd.
I am getting a very similar noise on acceleration. I'm going to do the reverse braking and hope I hear the sound. If this is my problem I am so thankful for this video lol.
I really hate when I start getting random noises from underneath.
I've dealt with U joints twice, a carrier bearing, a loose transmission exhaust hanger, and now this. It's so annoying because you don't know what it is!
Hope so. Let me know
@@PhillipBailey I tried to get it to do it in reverse but it didn't do it at all after restarting my truck. The starter makes sense though.. and with the window down it was louder on the passenger side when it was acting up. I will keep listening for the noise but between this video and one more I found on here, I think it was the starter.
@@PhillipBaileyI changed my starter and still haven't heard that noise but I have got a different noise, a lot louder but only lasted a second. I've only heard it a few times so far randomly. I think it might be the emergency brake pads . From the video I watched, they can also make a sound similar to this. I did look at my starter though and wasn't in very good condition anyways.
Got off and freeway today and noticed a weird rattle just like this one! 2002 4.3 v6 , it comes and out but even on the freeway i can hear it
The rattle in my 2004 silverado , was my wheel bearing dust cap had came off , tapped cap back on , a five minute job.
Had the exact problem on my 2013 Silverado. The sound was awful.
New starter installed and problem solved.
Thank you
Had a feeling this was the problem as I also noticed it only does it when the truck is positioned on certain angles lnew my starter was bad this just confirmed it will update once I install new starter
Just had this same problem on my 95 blazer. Crazy It would still start though.
Exact same sound my 08 4.8 is making!
Mine just started doing this exact noise and i figured it was the started and put it uphill aswell and sure ENUF the noise got quiter
Good find.
Update it wasn't starter after all pulled it and it was fine next on to a possible broken or cracked flex plate
Same problem same sound same uphill/down hill condition. Mine was a 2010 gmc though. Probably same starter.
Omg mine is the 2008. I thought it was my 02 that was stuck rich. I’m buying a starter tomorrow
Mines doing the same exact noise but then my truck stalls even though it’s an automatic my truck is ls swapped. The first engine blew a head then I swapped it to another lq4 and it did the exact same noise but it stalls and truck turns off and starts smelling like it was burning oil then we warrantied that engine and that one is doing the same aswell
My 2013 Suburban is making this noise exactly, and it started with a screechung noise and I thought a rock got caught between the rotor and the guard plate. Then the noise has been constant since then
If the noise is present sitting still and is engine speed related it's not in the brakes
People said i had a bad flexplate! NOPE! bad starter! thanks!
could this possibly be my issue if the rattling still happens when my truck is stationary? i have been trying to diagnose this issue for 2 weeks now
If it rattles when stationary then it should be easy to locate I would think. Lots of possibilities exist for rattles. Heat shields on exhaust manifolds, converters etc. Broken loose substrate inside a catalytic converter. Try tapping on exhaust components with the truck not running with a rubber hammer.
My 07.5 Silverado does something similar at all times. Not necessarily a tick or knock more of a rattle and u e been stumped I’m going to give it a look
If you can duplicate the noise sitting still possibly by brake torquing the engine while someone tries to pinpoint the source of the noise.
Thanks!!!!!!
I have a 2005 GMC 5.3 pickup truck. Here are the details of my issue:
When I first start it in the morning, the oil pressure is fine but after the engine heats heated up and about 10 minutes of driving I hear a heavy rattle in the motor...this only happens upon any type of acceleration from a stop light or even accelerating on the highway, or street, even light acceleration. it is a content issue from that point forward, until the motor is stopped and given time for the time to cool down... Also after the engine heats up, the oil pressure drops somewhat..., also when I first start the cooled engine, I notice a heavy blue smoke from the tail pipe, this only lasts for a few seconds and then no more smoke... It has about 160,000 miles.
Thanks for any advice you have to offer.
If you have any ideas it would be greatly appreciated.
Thanks.
The engine noise and smoke are probably not related. You may have excessive bearing clearances or worn main or rod bearings. hen the oil is cold it is somewhat thicker and will help quiet down a bearing knock. This would also account for the low oil pressure. You should have it assessed by a mechanic as this is quite serious if that's whats going on. The smoke is likely due to worn valve guides and or valve seals. goodluck
You magnificent bastard!
What part number is that
Will this noise happen only under low rpm in drive ? Mine is only rattling like that when I’m giving it very slight gas, but when I give it more it goes away, but when I feather the gas the noise happens
Usually on light to moderate acceleration from a stop
You might have saved me a small fortune. The mechanic told me it's the flexplate and it's $1200 to fix. Like yours, my truck would only make noise when accelerating and at idle while on an incline. I'm going to change the starter to see if that's it. I really don't trust this mechanic. He seemed shady.
At 2:10 in the video you can see the starter drive just falls in and out. Let me know.
Oh now you’re just teasing us I am a tool addict... where did you get that ratchet ? I want one! LOL
Got a 1/4 and 3/8 gearless stubby ratchets from Napa. I believe their ultrapro line. Fond them on Amazon look the same and cheaper: www.amazon.ca/Titan-4-Inch-8-Inch-Gearless-Ratchet/dp/B0009IQ2BE/ref=sr_1_11?dchild=1&keywords=ultrapro+gearless+ratchet&qid=1620693648&sr=8-11
@@PhillipBailey thank you very much! God bless you Brotha!!
Can this problem also cause an engine to lag or bog down during acceleration up a hill?
I seriously doubt that it would
I think you solved my problem it makes the exact sound as yours so you suggest I just change the starter.
If you can reproduce the noise sitting still say on a slope up hill you may be able to hear it rattling at the starter. No way to check this without removing the starter. Good luck.
Thank you so much the sound is identical as your video exactly Thank you so much I will get it checked ASAP.
Is it safe to drive a couple days before getting fixed?
I would say yes. My customer had this noise for 6 months and the starter was still working.
Did it only do it while the engine was cold because mine Is making a similar noise but it went away once the engine warmed up
this one was hot or cold but temperature could be affecting things.
Will it stop ur car from moving in drive or reverse but I have that rattle noise but my truck hesitated to park I had to u turn gud thing I was at home when it happened I had to push on gas hard to get it to go
No this won't affect the engine or transmission operation in my opinion.
What’s your opinion on it if you replace it with a new starter and it does the same thing???
Same here
Someone found the trouble? Have put a new starter but that not fix the issue..Thanks to answer.
My 2011 Silverado 5.3 does the exact same thing but it also hesitates sometimes to take off. Could that cause that too like sluggish takeoff?
No the starter will not affect performance in my opinion.
@@PhillipBailey that’s what I was thinking. It’s going to shop tomorrow,man at oil place said maybe it was transmission so I’m hoping it. It’s going in tomorrow
@@t94zskss47did you figure it out? mine is doing the exact same thing
@@ambertrevino2771 all it was the starter shaft broke and was trying to engage with the flywheel. Got a new starter put in and was good as new.
07 Yukon 4x4 here 5.3 mines isn’t that loud but kind of similar im going to check that next only does it when vehicle is warm did it happen to you on cold start also only happens to me when it hot outside
It seemed worse when hot.
@@PhillipBaileyhello Phillip. I changed out my starter. Still making the noise. Fades away at around 2500 RPM. Any ideas?
@@John1974 could be many things. Try removing the main Serpentine belt and the AC belt. Could be anything in the drive belt area.
I have the same noise and assumed the starter drive gear also. Changed the starter, and it was sliding like shown here. Put it back together, and STILL have the noise. Any suggestions? Flex plate? Torque converter? It's driving me nuts!
08 Avalanche 5.3
@nottabidenfan1228 when exactly does it make noise? If it will do it sitting still then you might want to take it to a shop with a drive on hoist or a pit. Exhaust leak, heat shield rattle, drive belt tensioner or idler, ac belt or tensioner. You could try removing the belts one at a time.
@PhillipBailey it happens only when I let off the accelerator, I hear a "click" and then feather the gas peddle slowly, and it's a steady "clicking" until I push the accelerator more or just coast.
I notice at slow speeds that once I hear the noise, I shift from drive to "3" and the noise stops. I understand it's hard to diagnose from a comment, but I appreciate your experience and suggestions.
@nottabidenfan1228 will it do it sitting still in drive foot on the brake giving it gas?
@@PhillipBailey no, it won't.
@@PhillipBailey the noise sounds like it's under the brake pedal/floor mat.
That can happen in 2020 2500hd silverado?? I hear something like that in my truck
I'm sure I'd could although the starter is different if it has Stop-Start capability. Would it not be under warranty?
Can this cause to the truck to shut off after acceleration and hard rattling on the engine? Mine does that sound and then like loose power and shut off
It should not affect engine performance in my opinion. I think something else is going on. Any codes setting?
@@PhillipBailey i had a code of a Evac I don’t remember what code was
@shmeed_tcg9787 if the purge solenoid is leaking it may run poorly at times and possibly set an Evap code.
@@PhillipBailey but I don’t understand why she starts knocking hard and shutting off like no gas in the engine
@shmeed_tcg9787 no gas to the engine won't make it knock. It will loose power and possibly stall but it should no knock. You need to start with a scan of all the modules to see what codes it reports, refer to code diagnosis. Also need to monitor data in the ecm while the condition is occurring to see if it's starving for fuel, running lean or rich. Check for induction leaks, skewed O2 sensors etc.
I was blaming the ABS pump.... Lol
Do this work for a 07 chev impala Lt 3.5
It's possible but due to the transverse mounted engine I would think the noise would occur mostly turning right.
Same exact thing with my 2010 1500
Glad it helped you out.
hello guys I have an 06 Silverado and my truck when cold idle or acceleration starts rattling sounds like metal tearing apart but she drives well anyone might know the problem
There are many possibilities for noises. Could be drive belt related. If you can reproduce the noise sitting still running cold you should be able to isolate the source with a stethoscope. You could also try removing the drive belt and the AC belt. The AC belt tensioner is also common to fail.
mounting surface on block has oil ??? please help how can i fix
I'm not sure what you mean by that comment.
@@PhillipBailey could starter cause small leak?
@@joshualagunas847 no there is no lubrication to it. If is oil it's coming from above.
@@PhillipBailey rear main seal ?
@@PhillipBailey i deff think oil comes out near starter. cashing damage and sometimes won’t turn over. i hit the starter for a quick fix tho
What about if its only on acceleration?
This problem usually only occurs on acceleration going forward..it won't do it under a load sitting still.
Dose this have an affect on power loss
No it will not affect performance I'm my opinion unless the knock sensors hear the noise and retard the timing thinking it's pinging. Not very likely at all.
I think you might have just solved my problems with that sentence. I have had that noise for a while now, and I started to get knock sensor codes even after replacing them with the new wiring harness, and now my 2000 Chevy Tahoe 5.3 LS just started acting like it was out of timing and is making a new weird noise on the bottom end of the engine. The damage MAY already be done to the engine and I'll have to fix it, but I'll be so pissed if all of this was because of the bindex on the flexplate 😅 I'm going out in a few hours when it's not so freaking hot out to change the oil and replace the belt tensioner, so I'll remove the starter then and check it out.
I'll try to remember to update this when I find out.
thank fuck i found this i thought my truck was a goner
Mine does this but at idle any ideas
Could be quite a few possibilities. You may have to put it on a drive on hoist and listen under the truck while it's idling on the hoist. Check exhaust and heat shields
@PhillipBailey figured it out. Was a bad ac tensioner pulley. Seized up and broke free. Which caused the bearing to break causing the rattle noise.
I have the same sound on a 06 now. I just learned the best trick to tell its the starter 100% is to just BUMP the key. not start it Just like 1/4 revolution you will hear the bendix going "ZING" and rattle. hhahaha. How many clowns you think junked these trucks thinking the engine was bad. Makes sense when its worse when It sounds terrible when backing up and slamming on the brakes I was playing before. I have a brand new OEM starter I bought back in 2012 when the OEM starter used to not work some times but fixed itself probably had water in it. So.. I have the part already Ill try to fix the original one GM used the same fork and bendix 9 tooth on a TON of vehicles not even LS 4.8- 6.0 stuff
Yes you are correct
@pBailey Yea took it out today its a rattler. Put in a new starter i had since 2012. The solenoid lug busted off of it and my big Snap off tool collection lol. I have no E torx DEEPS bigger than E4. Its a e5 for the solenoid. Now I have to wait for tools lol Sucks, You probably have a shop. I used to come across it now and then usually on rusted vehicles when the damn solenoid stud breaks off the battery cable. hate that crap. The new one the way it was shipped
(Delco) years ago had no support maybe it had a hairline crack it tore out the lug just too easy with a baby ratchet. Like those 3 inch or smaller snap on 1/4 ratchets. Atleast Old Rattler still works to bump over the engine for another day or two. Got to love our country now. No one even sells solenoids anymore. If they do OF COURSE its Chiiiiinnnnnaaaaa ... At crazy prices
That’s the same noise as my truck
Definitely was a challenge to locate the first time. Hope this helps you.
Oh my goodness gracious lord bless you I’m putting my coveralls on right now! My 2000 Silverado 5.3 is making this noise and driving me squirrel shit nutty ! I pry this is what it is
Dude! God damn it you are the motherfucking man!!!!!!!! My 05 Chevy Silverado 1500 5.3 crew cab with the same miles had the same exact problem. It was driving me nuts months of researching till I found this video sure as shit that’s what it was! I love you thank you!!!!!!!!!
