Grizzly Locker and 456 Gears on the Street - Is it Bear-able?
Vložit
- čas přidán 21. 04. 2021
- This time in the AutoEdits garage... we stuff a Yukon Grizzly Locker, stronger axles and 4.56 gears in the 1995 OBS Chevy Tahoe.
I don't do this install myself in the garage but take it to a local shop called Hooper's Rear End Exchange 818-899-2515 (support your local business!) The main reason for taking it to a shop was to get it done fast and with some confidence since I'm leaving on a trip tomorrow in the Tahoe!
Unfortunately this upgrade isn't cheap but it is a really good one. I could have saved a bunch by doing the install on my own but the tight schedule meant I had to take one for the team and hit the credit card for this one. For your reference, the labor cost was about $950.
I'll run you through the full parts list right here...

I'm loving this Tahoe build. It's great to see someone take a budget friendly platform and do upgrades that make sense without breaking the budget. Great job Jason, would love to see more like this in the future.
Thanks for the input, I plan on much more!
Poor Ram J sitting on the side with his open rear end and watching the new kid have all the fun hoping Mr Jason will call his name again some day ;
This is so true... I truly love that truck... the Tahoe is just fresh and new 🤣
Can't wait to see more of the tahoe! Keep them coming.
Great content as usual. So easy to watch. The behind the scenes footage at the driveline shop was excellent!!
Much appreciated!
I picked a 95 Yukon (green) for a great price as well, low miles and you are providing all the info I need to turn my ride into vehicle that frankly I would never want to sell. I love driving around rural Utah and I cant think of a better vehicle to do that in. Keep up the great work!
Right on! Thanks!
awesome upgrades! I just re-geared too, what a huge difference that makes driving. Just completed the initial 500 break in and trail ready now!
That is awesome!
Its fun running stuff like that on the street. I put a mini spool in my 88 chevy half ton 4x4. Had a 383 pushing 450hp. Drove it daily for 5 years. Even delivered pizzas in it for a year. Anything is streetable as long as you know what to expect.
Just found this channel! Nothing over the top for us average joes. I need this locker in my l5P!
Welcome aboard!
I had a lunchbox locker in the front of my JKU, which was a daily driver. The looks I got from people while I was navigating through a drive through for my morning coffee were great. It was almost as fun doing that as it was wheeling the Jeep lol.
That does sound like a handful!
Love your videos. Always informative and entertaining.
Glad you like them!
This thing is gonna be such a dope build
I think so too!
Yes!! Was just thinking about when this would get uploaded 👍👍
How about now! LOL
SICK!!!
Late to the party on the Jeep Build so I'm keeping an eye on this build.
Thanks!
This thing is shaping up to be a BEAST
I have an old '96 Jeep ZJ project vehicle. It needed a whole new rear axle assembly. So I put in a remanufactured one with a TruTrac differential. With just heavy duty Auto Zone shocks, the stock 4.0L makes a pretty good adventure vehicle. I did upgrade the tiny 215/75-15 tires to General AT2 255/70-15 tires. It does fine in the desert near Jawbone and Red Rocks State Park. I really have been working too much lately to go much of anywhere with it.
I did buy a '23 Jeep Wrangler Sport S Lattitude for my wife the other day. That will probably get TruTracs front and rear, with the stronger axle shafts. I am considering portals from Weld74 instead of a lift kit or gear change. I like the idea of moving the pumpkins higher. This Jeep is intended to be towed behind our diesel Ram 2500 carrying our 4Wheel pop up camper.
It is fun watching all your videos over the years. I live over the hill from you in Quartz Hill. I have been on many of the streets and off road places you show.
Awesome video. I love those kinds of shops. Gears are their specialty, it is what they do! I learned the hard way to NOT use an Offroad shop to do gear work. It’s much better in my opinion to take it to a place that just does only gears! I had a grizzly in the front and rear on my 1993 YJ and I absolutely loved them on the trail and they were fine on the street too. I loved not having to engage and disengage lockers on the trail.
Right on!
Best damn channel on the ytube! Editing is on point, educating, and no friggin annoying EDM intros. Great work!
Thanks soooo much!
What a great video! Love the way you broke it down.
Thanks so much!
Lovin the build, similar philosophy to my squarebody. Also love the buckstop bumper, ive been eyein one of theyre retros for a while now
Wait... I never noticed a retro... now I'm going to go look!
Awesome! Good demonstration for the need of a locker.
Thanks for watching!
That locker is very cool. Definitely looks like it is performing well. Another obs at @6:32 , maybe could offroad together! Rear shock @6:50 isn't happy, but you probably already knew that! Really digging the Blue. Please keep the Tahoe videos coming!
Good spot on both counts!
The Tahoe is growing up so fast...😂🤣😂. I can’t wait to see what you determine you need next after this upcoming adventure 👊🏻👊🏻. As always awesome stuff...thank you!!!
Thanks so much!
@@AutoEdits I am having the same locker installed on my yj this week....it’s great to know what I can expect 👊🏻🐶
Nice truck! I love old Tahoes!
Me too!
I don't think you drive in snow often (Maybe if you go to big bear or something?), but if you do, know that an automatic locker can cause snap oversteer. Sometimes there wont be enough traction just driving to cause it to lock (it needs differentiating forces to lock). But then one tire may spin more on a corner or uneven piece of road, and it will suddenly lock and cause the back end to kick out. You get used to it, and you have an automatic will make it less likely. But something to be aware of. You may also sometimes get the "bang" that happens after pulling out onto a road where the locking collars are between teeth, and then they will slip and lock. Which will cause a loud bang, and make the truck jerk to one side a bit. And since you have an automatic, you should not need to worry about "shift steer". Where you shift from typically 1st to second on a slight corner, the locker will cause the vehicle to go straight instead of the slight turn. But I have only ever had that happen with manuals.
This is valuable data. I'll be driving in a blizzard tonight so we'll see how it goes.
Perfect timing on this find. I need a beefier axle for my Sub build. Love me some Yukon gears.
Right on!
Great work mate!
Thanks!
For the people interested in a auto locker I have a Detroit locker in my Tacoma and it is quite. I’ve had it in there for over 60k of daily driving and I drive pretty aggressive and it does lock occasionally while turning sharp but I drive it sometimes over a week without it locking up but when your on the gas pretty hard it locks no matter what. And I’ve not noticed any extra tire wear I will be putting a Detroit or grizzly in my next vehicle. I’ve also taken the truck down the dragons tail before and it was slightly annoying there but other than that it is by no means a nuance
That clicking all the time would drive me nuts 🥜
With the windows up you don't even really hear it... I realize that all the shots I used the sound from the gopro right next to the diff. so it seems loud. But yeah, it's not for everyone.
It mostly goes away after a while, at least in my case.
You get use to it. It's honestly funny to have random people come up and tell you that your rear end is about explode when you pull into a parking space or gas pump.
That clicking sounds like cv joints on the front axle.
Turn up the radio0🤣🤣🤣
I've run front and rear Detroit's on my 1998 f3-50 and once you get used to it, its no big deal all that changes when its icy or snow-covered roads then you have be paying 100% attention to what your driving on or it will spin you fast lol that was a quick learning curve
That sounds terrifying!
This build is so good can't wait to see what you'll do next hopefully it's a rear bumper 👀
That's the plan!
Holy crap that's Hoopers ! Lol I'm taking my rig to them soon for either Tru Trac or Grizzly locker! Lol what are the odds !
I love this series. Regular guy stuff.
Thanks! Some of this stuff still gets expensive but it sure is nice to start with an inexpensive platform that is this good!
When you take your Tahoe off road, lower your air pressure to get more grip. Also it will help from the fire getting punctured. Just a heads up
Love this Tahoe. It seems that the lower shockmount is a little wiggling. Maybe its only on the video. Big hug to Pinto. 😍
Great spot! Yes, I knew the shocks were wasted but when I was editing the video and watching the shock bushing wiggle so much I was shocked...lol
Needs new ones really bad.
I think the cons of a Detroit/Grizzly locker are overblown. I have a Grizzly in the rear with a “lunchbox “ locker in the front of my ‘16 JK. After a couple of weeks of daily driving everything was broken in and they’re basically silent. They’re noisy in really tight turns and every now and again you’ll get a bang, but I don’t regret getting them.
This vehicle ended up spending most of it's time on city streets and freeways and was absolutely fine.
Fellow Gmt400 maniac here. Good odds your tires are scrubbing the rear inner fender-well while articulating also limiting your flex. Happened to me on my Burb. Opted for the wheel spacer quick fix.
Howdy and thanks for the tip... I'll check the wheel well for any signs of rubbing!
I have a Chevy blazer 1993 Silverado 4x4 model . I shall use same.
Thanks for sharing
It's been great so far!
Great video👍. I'm planning to swap my 3.23s for 4.30s on my 2017 Cadillac Escalade.
Nice 👍
Its wild that my 97 Z71 came stock with 4.10 gears and a rear locker. All it needs is a front locker and no mud hole could stop it.
I think it's called calipso blue
Best demonstration I've seen so far thanks!
What about the odd loud 'bang' or 'clunk' I see on some other videos. Have you experienced it?
I have a Yukon grizzly locker and Yukon 4:56 gears in my 2wd 2013 Silverado that thing has been threw everything desert , river, glamis this is a perfect set up for best of both worlds.
I've been really happy with this setup so far as well.
Wooooooooooo!!! More Tahoe content!!
Yeah buddy!
I ran 4:56 gears for many years in my 1967 C20 with the stock eaton rear. I even drove it from salt lake to bismarck. Yeah it was slow going but as long as you don't mind the slow lane it's very doable.
This thing seems to go down the highway at 75 with little trouble... about to hit the road for a 1,000 miles or so... we'll see how it does!
@@AutoEdits you should have no problem with that setup, I did mine with a TH400 so no overdrive, 3500rpm at 60mph. I run a 14 bolt in that truck now with a yukon 3.73 and an eaton trutrack. The truck is retired from heavy hauling, so I just set it up for a bit more freeway speed. Thanks for the reply!
Great video 🤟
Thanks!
Taho upgrades on gearing great choice
I think so too!
On this episode, more Dad Jokes an a lil' off road action. Looks like its ready to do some over-landing camping!
I even put a dad joke in the title LOL
Awesome man!
Thank you! Cheers!
Them are some beautiful axles
I think so too!
Great video
Thanks!
That Tahoe is super sick dude! Love it!
Appreciate it!
I was going to get a grizzly locker but that clicking is ridiculous and im sure it isnt good for the unit either. Gonna go with a Duragrip instead thx for the video it was helpful.
You need tuning from blackbear performance! Best thing I’ve done to my 97.
I was watching & was going to comment on something but completely forgot what I was going to say so... Here I am, for the algorithm!
Love this, thank you! The algorithm hates me for some reason...LOL
You called it, ice and snow is a different story with a locker like that. That rear end will kick out in a hurry. 4 wheel drive of course helps keep it to a minimum.
I'll let you know... did good on light snowy roads last weekend!
@@AutoEdits Boss, I’m following your footsteps with my ‘02 Suburban Z71. It’s our family vehicle. Would it be dangerous for our family to run the Grizzly? We want to take it out to the snow.
@@klumsytone I'm not sure about that. My last trip into the snow was in the Jeep and there were plenty of times that NOT having the lockers on felt way better on icy stuff. For everything else... the Tahoe is feeling very useable with the Grizzly. If I were to be building a family hauler, I would build it with the posi-trac or e-locker.
Dinner and AutoEdits. 🤘
Yeah buddy!
Interesting and informative
Glad you think so!
Definitely make sure you rotate your tires when you have one of these, lol.
For sure!
The 8.5/8.6 10 bolt is pretty much equal to a Dana 44 (give or take a bit here and there). I'd consider 35s the max.
Number 1 fan here
Thanks dude, I count on you! LOL
It would be interesting to see how a grizzly locker would perform in adverse weather conditions, be it rainy, muddy, snowy, or icy roads. It probably helps that it's in a full size truck than it would be in something small and light like a CJ-5 /CJ-7 jeeps.
Yes, the longer wheelbase does make it very live-able.
I use grizzly lockers in my one ton Jeep and my wife’s daily JK. Awesome in the dirt, a bit clunky on the road.
How much did you paid for the lockers?
Nice work once again, love the shirt BTW, I hope she is mending up well. Do you have any advice about a rear end upgrade for a 2008 Toyota Tundra 4x4?
Howdy, pinto is doing pretty good thanks! Email the guy I put in the description from Yukon and ask what he recommends!
@@AutoEdits Thanks Jason!
Didn't know Hoopers was still there. I went to school with Lance.
Cool
3/4 leaf springs mount to the back of that with very little effort. Not only do they make the towing capacity better but it also is a 1 to 2 inch lift when doing this.
Thanks!
Nice upgrades, fun video! Hows Pinto? I'm sure he missed coming for the ride
She’s getting better very slowly... thanks for askin!
Great video. Is this similar to those lunchbox lockers? I got a 2000TJ and thinking about getting this now. I also thought the clicking noise would be loud enough it would sound like you got major mechanical problems 😅😅
It’s not that loud, I used the audio from the GoPro right next to the diff ... with the windows up you don’t really hear it. The grizzly is MUCH stronger than a lunchbox locker and better all around.
Now you need an E-Locker installed in the front axle!
WEWT!
I'm a bit nervous stuffing an e-locker in the front. Seems like asking to break stuff.
@@AutoEdits
I've got one installed in both of my trucks.
The key to not breaking things is: you're trying to CRAWL over things, not treat it like a rock buggy.
Slow/steady throttle.
If the vehicle starts hopping/ bouncing,
back off, and choose a different line.
@@AutoEdits
That 'pinging' noise you heard during that climb, was the sound of your driveline binding up, and spring loading/dumping that energy all thru the front tires, that were bouncing the loss of traction between them.
(THAT is how you break things)
Notice: your rear wheels maintained the same rotational speed during your climb.
Oh, and, lower your tire pressure a bit more.
(I assumed you didn't, simply because it was a quick demo)
Seemed to run good even without the mods!!
You are right... it did run pretty dang good before the re-gear but it feels perfect now.
Very cool build so far. Did you consider making quick-disconnects for the front sway bar? You get tons more articulation out of the IFS that way.
You don't want to do that on an ifs it's a recipe for a broken cvs or even tie rods.
Thanks for the suggestion... would doing that put the half shafts in too much stress?
@@AutoEdits I run 37s on a 2500 2001 burb. No sways up front and really beat on it in moab and in Colorado. CVS can take it. It's the tie rods you need to worry about
Half ton CV’s grenade if you are spinning tires and bouncing the front end while turning. If you don’t wheel like that you might be fine haha
Could you share how the locker responds to wet roads, snow, mud and daily street driving after driving it for a while? I'm considering running one in a crew cab long box 4th gen Ram. Thanks.
I would also like to know
Thanks to you I had them fix a bent rear axle, but have a 97 k1500 that I want to install that exact locker and was wondering how much was it installed?? No 4.56 gears
I'm not sure... I "filed" the receipt and can't look at the price breakdown at this point.
Nice work. I’d also like to know how you like the Milestar Pat MT’s as a daily drive tire. I’ve got 36K on the set I have now, and only get to off road a few time a year. Suggestions?
The Patagonia MT's are a great all around tire. Love them as a daily driver.
Idk if that'll cause more or less tire wear than an open diff my 97 tahoe (33"s and 4.10s) if I took off like you did I'd have to let off the throttle because it'll spin my inside tire like I was trying to do a burnout
Road trip! Road trip! Road trip!!
It’s happening!
I put a spartan locker in my grand Cherokee and it clicks when I turn too, i got used to it, you do need to be careful in the snow or ice if you're only in 2wd, it will get loose on you, i just leave my jeep in 4 high for the winter, North Idaho
Great suggestion! I've only been in the ice once and since this truck makes so little power (LOL) it didn't feel that sketchy but I get ya. The only time I really feel like it's a bit sketchy in my usage is in emergency stopping or "panic stop" situations on the freeway from high speeds... the locker combined with drum brakes creates some drama in that scenario but otherwise live able.
Hoopers is legit 👍
Yep.
I have the same year tahoe that I am starting to do a similar build...with everything you have done so far what are you out of pocket in parts and labor for things you couldnt do in your own garage?
The gears and locker install cost about $1500
Hey Jason, I was wondering if you started to experience any hum after installing the grizzly locker?
I really paid attention tonight when I took it out for dinner and the thing is quiet as can be back there.
Have the same locker in my Toyota on 35s” do you get a big clunk going from forward to reverse or vise versa?
Sometimes, not always.
just found your channel and i love your videos especially the ones with the tahoe, i have a red 2000 z71 obs.
how are the tires so far?
Love them... nothing not to like.
@@AutoEdits sorry i should have been more specific, do they rub have you had any issues?
@@robmora2703 go watch his tire install/test video!
@@daveburkart2363 iv seen it, what i’m wondering if he’s had any issues since that video, after a couple weeks has he had any issues
Going with the Eaton TruTracks
Very smart choice.
OK, Yukon's version of Detroit Locker. Funny when riding with people who don't know and it starts clicking....Dude, what's wrong with your car! 4.56 seems little steep but then you got those 35's. Let us know if your gas mileage suffered a lot. You're lucky to have old school shop like that near by. They're becoming few and far between.
Yes, exactly like a Detroit! I didn't re-calibrate the speedo yet but I'll do my best to check mileage on this next trip!
In total, how much did it cost for locker, shafts, labor, etc...? I need this for my truck. Going to go for 4.10 gears as I plan to throw 33s down the road.
I put the labor in the description and the parts may vary depending on sales.
@@AutoEdits lol, totally missed the show more lol. DUH!
Looking Good, The Height looks nice and the tires looking awesome. With the gear change, how is the gas mileage also what's her name?
Thanks! It still gets around 18mpg on my last trip and it doesn't have a name yet!
Just to clarify, that was a 4WD climb up the hill, not 2WD? It appeared the left front may have tossed some dirt.
I had it in 4wd yes.
great video. i have a 97 Tahoe 4x4 and i've worked with Anthony at Hoopers for a long time. They've done 2 10 bolt rears ends with eaton posi's in my Tahoe and i finally asked them to upgrade me to the 14 bolt and eaton posi. so far so good. i'm also running 4.56 gears. its perfect for this truck. im gonna look into doing more of a locker in my 14 bolt because the eaton i have in the 14 bolt is a bit disappointing. im also curious if there is a posi unit for the front of these trucks. i understand a locker in the front is not ideal due to the weak components up front. mainly the case.
Great to hear from you!
@@AutoEdits do you know of a front posi, limited slip or locker for the front of the Tahoe?
@@miaatch1 I do believe Yukon makes a limited slip for the front of these but I don't know the part number.
Hello. I know this question has nothing to do with gears but have you ever experience problems with the blinkers not working and reverse lights? Need help. :)
Check the bulbs then check the relays/fuses.
Was it limited slip pre locker??? If the truck goes off road a locker is a no brainer. IMO. Really liking the content. Very well done
It might have had a limited slip but it was worn out after 235,000 miles.
I was like number 666. Sorry. Someone had to do it. Lol keep up the good work. Love the videos!
No worries!
So for clarification, this diff is locked 100% of the time, apart from when doing tight turns, which is the clicking noise?
You got it!
@@AutoEdits thank you! Awesome rig, used to have a 98 Tahoe before going to school, one hell of a rig and I miss it! Great video and best of luck on your build!
This video just sold me on a Detroit/Grizzly for my 2500HD to replace the G80.
I've been very happy with it so far.
@@AutoEdits Grizzly and 4.88s in my Duramax are awesome. Would love to see some more of the Tahoe.
How are the grizzly lockers work in snow and icy conditions? What are the pros cons ?I live in Canada
In snow it is great... I've only driven icy mountain roads once and it was fine. Not having much power really makes it kind of easy but I was cautious the whole time.
Did your Tahoe have the OEM locking differential on it before you put the Grizzly locker on? I think it is designated The G80?
It did but it was junk. czcams.com/video/4HAc4h4dOlk/video.html
@@AutoEdits I watched that other video (great videos by the way), but maybe missed a part about the G80. Is the G80 junk in general? Does it just not function well or is it just prone to breaking down?
@@mikezuerlein6564 This one had 225,000 miles on it so it was understandably weak but I've learned from many comments on these videos that some people like them but most don't.
4:56 gears??? Prolly red lines @ 65MPH...BUT....from 0 to 65..hell yea!!!!!
czcams.com/video/SLxA9hlW9y8/video.html
how does the Grizzly compare to a factory G80 locker?
The factory "locker" didn't work at all. This is an actual locker and is fairly aggressive for street driving but is the easiest form of maximum traction for my setup.
Does your locker clunk when you put your truck in drive and reverse? Thanks
No it doesn't.
I have that same cover for my truck.
It's a good one!
Crap, i should have waited for this video to come out before changing mine. I didn’t think of changing the axles. Ill add it to the to do list..
Stronger axle shafts are good peace of mind !
I don't think I could live with that clicking on my daily
The sound you hear is from the camera right next to the differential... from inside the cab it's not that bad at all.
You didn't like the g80 locker in it from factory?
My g80 on my Avalanche works ok, no clicking noise when on pavement but the wheel has to slip a turn or 2 for it to engage
That thing was fully worn out after 232K miles or broke because it would one wheel any chance it got.
Yukon is a great replacement over the g80. g80 is good for oem, but the yukon is an upgrade.
Gov bombs blow up often. Avoid for serious off pavement use.
