Tearing apart blown Chevy rear-end

- This Chevy truck has the G80 gov-lock, limited slip differential. These LSD systems are highly prone to failure. When they fail, they typically break spider gears or crack the carrier. In this video I disassemble the differential to get it ready for an overhaul. Often these differentials can be challenging to disassemble due to the fact that most of the components are damaged or distorted.

Yes this no nonsense no trying to sound like supper tech just show me what I need to see and move along, you are awsome man
Ahh yes the Gov Bomb. Blew mine up on Saturday doing 65mph down the road and all of a sudden it just locks up 😂 got parts on the way so it shouldn’t be down for to long.
Deadblow hammer and heat of the momment on tune love it. Had my suburban diff explode on me. This video inspired me to not give up. Thanks man!
Thank you!! 🙌🏽👏🏽 your video came in clutch I couldn’t get my carrier out and your technique with a wrench on a bottom bolt of the ring bolt to stop rotation while prying on the top bolt of the ring took me 2 seconds to do after an hour of getting no where! Grateful! Thanks for this great content!
That's awesome, glad you got some help from the video. Thanks for watching!
Just had my g80 granade on me thanks a ton this video helped me with the disassembly alot
That bullshit don’t work they want you’re card info tried making me pay.
G80 diff lock is actually very, very robust. This truck probably has a oversized 35" tire (there's like 5" lift you can see in the video) and the driver was wheeling the shit out of this. He probably put pedal to the metal while rock climbing.
They're horrible! Those two spider gears spinning on a bare metal shaft is a dumbass design. Also the lock up is quite violent when it slams into lock mode. There's a reason these things have a reputation for bombing, then removing that pin to replace it can be a nightmare!
@@Mr_Ruhl Any aftermarket options available for a 2018 Diesel ZR2? Mine's currently screwed, with the center block carved away, and i'm either going OEM or aftermarket. Just can't find any aftermarket options out there.
Sounds like someone is compensating for having a g80 and not a lsd lol g80 is junk it locks the tires up completely and gets the job done but the way it violently locks up is why they are known for exploding when it locks up it puts extreme stress on the spider gears and diff carrier awful design get a lsd lol
This is accurate
Holy lift blocks Batman!
Great video yet I have a Chevy Equinox Awd and had the passenger side rear axle replaced due to issue at wheel end , yet it’s hanging out 3inches from differential and no longer flush... do you think this happened due to replacement of new axle the c-clip was not set and locked properly? I’m trying to understand why this happened, it was done 8 months ago? Any thoughts would be greatly appreciated
Great video my man I’m trying to diy this rn. Helped a ton
👍 nice work!
Thank you for the help.
Trying to get the center pin out of my 93 2wd sierra. It moves about half and inch but won't go any more. I've tried hitting it but I have no luck. The rear end was rebuilt 2years ago(previous owner) except for the oem carrier limited. Really need advice. Thank y'all.
How hard it it to replace those nesting gears in the differential. I got the whole unit out of the truck and only thing wrong is the nesting gears starting to grind. It's pretty much the same as this one. A gm locker on it
Is the G80 used in the trucks the same as the G80 used in the Astro/Safari vans? I'm about to buy a 2005 Safari and it has the G80 diff. Should I be concerned?
Thanks for the video
Does ANYONE know where i can get the tools to disassemble the governor set up on one of these differentials
G80 and the gov locker are not the same rear end. One was from 73 and phased out mid 80s, the eaton g80 was introduced afterwards and is still in use today. That truck looks like its modded and driven by a jack ass. Probably blew it up themselves. But main point, is thats not a gov bomb
To make it easier on pulling that spider pin, just spin one axle or the other a little bit and it will slide right out. I kinda cringed a bit when u put the bolt back in and pryed on it lol.
It was bent and new rear end kits come with a new pin and bolt
Had my rear pinion seal replaced today, mechanic told me it needs a rebuild because it has some play, not making any noise.
If I buy a rebuilt kit, just new bearings and stuff. What am I looking at for work?
Don't do it yourself 😂
How do you know when it’s locked up?
The G80 is not "limited slip" as you mention in your description, it's a locker.
@Steven Blodgett the gt4 code is for the ring and pinion gear ratio. The rpo code for the locker is g80.
What's that intro song?
Here's the thing with these rear end's. Eaton made them specifically for gm and they are rated by eaton for gm and gm builds a vehicle around that rating and it will last for years but like all moving parts they will wear and adding stress to moving parts to which they are not rated will cause damge. That being said eaton also created such things to handle that stress in 14 bolt 9 and a half and 14 bolt 11 inch specifically for this purpouse. Now flooring a thirty year old rear differential with 300,000 miles on it and the oil has never been changed doesnt make it a horrible thing or putting giant wheels and tires on a high speed diff and trying to take off like a race car doesnt make it a bad thing. Now using as the manufacture built around it is one of the most awsome things ever created for a vehicle especially a 4 wheel drive. Yes i have broke them but i was way out of specs and mostly due to my own ignorance. That being said i have broke one of the drive gears in one and if not for the locking thing i would not have made it home as it would catch and turn the other wheel until it released at 20 something mph and start free spining so i let off the gas and slow down and get back in it and it would lock again and away i went yes it took a while at this pace but i wasnt stranded and made it home. I now have a 14 bolt corporate locker in place that can take a beating and changed 3.42's to 4.10's with my 4 inch lifted suburban 4x4 and big wheels and tires you know the proper way and it is literally a monster. Easy turning nice and smooth no binding from stress. That thing will pull a house apart as before i would pull the truck apart.
Hey , to start you gave no audio on what you were doing that might help someone doing this for the first time.
What's the round thin piece that fell that's what's broken on mine
left side carrier bearing shim
Need help !!! That little pin/threaded bolt you took out at 1:20 ish has snapped in half on mine. How do i get it out ?
1:08 i mean
U fish it out: only way
Maybe a magnet unless its broke off above where the threads start. Then drill it and get an easy out or something along those lines
Glad i only see it on the 1500s
I got the same moto metals on my truck
I like your channel I have subscribed 👍
Thanks for subbing!
What do you recommend if the middle pin is stuck
spin the wheels
Where you located?
Holy Cheetos not looking forward to doing this at the junkyard today .. I have a lot of play when I spin the rear wheels on my 2000 1500. The clicking sounds like there coming from the driveshaft . I’m doing uJoints fersure but my dad wants to remove the spider gears and switch them out again(we did this two years ago) he said the truck feels like it binds when it wants to shift gears. He doesn’t think it’s the u joints because there’s no slack in them. I just don’t want it to be that part you removed in the last two minutes of this video ha ha haa..
Dude that shit was bad ass. You bent that rear end over and made it your bitch. Mine exploded today so good inspiration 🤛🏼
You skip most of the center pin removal! Lol mine f'd all worn to shit and will not come out. Any tips?
Heat errrr up
Awesome vid except you didn't show how you took the driveshaft off
Don't abuse these differentials and they are just fine.
do they give any signs of failure at all or just boom its done
Mine gave out at 240k in the Rockies and its started to click around curves and I had about 3 hours before it shelled out, i probably could have made it farther if i didnt continue giving it the beans!
Mine had no problems at 250 thousand miles and stock tires and rims until I floored it one night after a few beers . It made a loud popping sound and I knew immediately what it was. luckily I was right by my house. It would drive straight but turning made an awful sound.
@@jamesfarmer2748 I know this is old, but what did you have to replace? Just the Spyder gear or the whole unit? My truck is currently doing the exact same thing.
@@Mr_Ruhl the ring and pinion and carrier were destroyed. At the time I found it easier and less expensive to find an entire axle from a guy parting a truck out with the same 3.42 ratio as mine. Changed seals and oil also. The replacement also had the g80 so I try to take it much easier now. I have since acquired the tools and know how to rebuild them.
@@jamesfarmer2748 damn! Thanks for the info. Strange it messed up the ring\pinion and carrier, but still drives straight perfectly. The only time mine makes noise is around a corner under throttle. I can coast around corners and drive straight and nothing seems wrong with it at all.
No sense in me paying the shop to rebuild or replace mine... how bout I just pay you. What ya say? 2003 chevy 2500hd 4×4 6.6 duramax with Allison ttans. 3:73 How much?
I found the problem right away 35s? On a six lug
Funny. I run 37s on my 6 lug.
Oh and i just blew up my yukon 4.56 locker. But i do frequent speeds of 85+, tow a boat and beat on it offroad
Pog video
I have same rims lol
Multiple songs to get the shaft out?
I’m disappointed.
Find me a 2005 Chevy Colorado 4 wheel drive rear end it's 3 .42/1
I have a brand-new one need 4000
Mine lunched itself at 145k
Mine dinner itself at 206k
That must have made some terrible noises when it exploded.
Mine just did the same, it definitely does lmao
You need to get a Ford 9 inch problem solved
good music though
Well who ever you are make another video about fixin what you tore up and we will all learn right along with you cause it's been 35yrs since I even changed differential oil but I have tore them up before. getter done
Operator error
"These LSD systems are highly prone to failure" Incorrect. The G80 has been used at least as early as the 1982 model year and...they are fine. The problem I see is a failure between the headrest and the steering wheel. Some "expert" had to take a well engineered truck and "make it better" with the lift kit and oversize ties and who knows what other shitty mods were done. I am on my 4th silverado and I haven't had a single issue with the G80. I am at 279,000 miles on my 2009. Running fine. Then again, I left it alone and drive it with some intelligence.
the problem is when the locker engages at high RPM, a manual locker is engaged before you accelerate (unless youre an idiot) if youre offroading and you try to blast up a hill, it'll break, if youre trying to accelerate hard in the winter on a slick road, it'll break
the correct driving method with a g80 is keep it in the low RPM, let it lock, then accelerate, they are good an reliable units as long as you don't drive like a jackass, or want to do series offroading, in which case, upgrade to a manual locker before other mods (and depending on the year, build up the 4L60 as well, those cant handle much stock)
And the fact this had a big lift and big tires on it.
@@dustinoverbey6068 Except no it won't do either of those things, because if just stomping the gas on an icy surface actually could they would never be used given that the major point of the damn thing is improved traction in slippery conditions. The reality is that about the only way to blow it up reliably is to ridiculously over-reving the engine on a surface where one wheel can slip.
The simple fact is that saying these units are 'prone to failure' is a straight up false. They do not cause routine issues in stock vehicles that aren't driven incredibly stupidly at all.
My hopes of wheeling my truck are crushed, is there a fix to prevent this from happening or do I have to swap the G80 to something like a Torsen diff... Befora any of you keyboard warriors types in a reply: it is not "designed to spin the wheels"... "waaaa waaaa"...
#1 It its my truck
#2 Ill do with it as I please
Terrible camera work
Not good work by any means. He used hard(not brass) punches which have now permanently scored the housing. Also didn't think about where the shims go.
Well, seeing as nothing that came out would be going back in, thinking about "where this shims go" wouldn't really mean much seeing as I would be setting up a new gear, but you knew that. And it doesn't take a precision shot to knock out races without scoring the housing. Thanks for watching!
Pink calipers WTF maybe the owner is a woman or a gay, plus pick ups are considered a "she" why the laugh tho?
No follow up videos. Only one actual install video. This guy is apparently at the bottom of the totem pole in this shop and likely is lacking the skills. What a waste of time.
Make your own videos then.
LOOKS LIKE A BRADY LOW PERFORMANCE HAMMER JOB >> ANYTHING TO GET IT DONE QUICK --- WITH ZERO REGARD FOR DOING IT CORRECT-- JUST ENOUGH TO GET PAID ---& IF THERE IS A DISPUTE -- HE WILL IMPOUND YOUR VEHICLE & CHARGE CRAZY STORAGE FEES--- SO >>> HE WILL OWN YOUR VEHICLE .
get a new camera man - STOP MOVING !!!
He's wearing a camera on his head. He is the cameraman. POV means "point of view."
