This guy is an actual mechanic, excellent diagnosis of the problem. I would suggest just replacing the broken shaft (if possible) , the clutch packs (plates) may never have been used!
Thank you, I did some research before hand so I kind of knew what I was looking for. I was honestly thinking the same thing with the clutch plates but then again with the fluid that came out of the diff who knows if that has ruined them. either way I think just the shaft assembly is like 100 dollars and the clutches are another 150 so I'm probably going to do both.
thank you! ya the differential is a pretty cool mechanical device and it's kind of crazy to picture how fast it would actually be spinning at like 100km/h
I had to use a map gas torch to heat my diff fill plug to get it out. I replaced it with a 1/2" brass pipe plug that can be removed with an allen wrench.
Hey just took the cover off my sons 97 2500 2wd and it has the same exact problem! Do you have any info on what you did to fix yours? I’ve worked on cars for 25yrs but mainly paint and bodywork never tackled a rearend but sure I can do it. Any advice would be greatly appreciated bud
You have to remove the governor parts and get them out of your way. There is a company named Kent Moore they make specialty tools for GM. They make a tool that looks like a small C clamp to remove the bushings holding the governor in. I've had mine 35+ years but can't remember the part number. You need the tool to take it apart.
no not really I wouldn't call them special. they are nice to have though. and when they are working they work very well. I mean parts are cheap. for the flyweight assembly its like 130 bucks. whereas a new diff carrier would be like 500-1000 dollars depending on what i wanted
The middle pin on my g80 in my 2001 Tahoe is stuck I can’t get it to come out it’s like stuck but when I turn the diff the pin spins with the diff I’m been struggling trying to hammer it out but nothing
I need help rebuilding my g80 gov locker... I know a few things about it since I took it off my truck but I don't know how to get it open to replace the gears. I'm too far into this to not finish it myself, just need a little guidance
i have a Chevy 2500 2009 the differential locks up when turning I hear a pop and locks up the rear tires and then I reverse it a few feet and it unlocks any advice on what to do ? might be the Gov lock ?
These G-80s are innovation for sure, but no, electric lockers controlled by the user should be the norm. I see GM finally did it with the ZR2 Silverado both front and back and this is what should be happening moving forward.
Noticed GM stock has been reflective of there fine manufacturing,,,, "all over the WORLD." It's only a matter of time and they'll go the way of RAMBLER and STUDEABAKER.
There awesome when they do work,i had 36's and never had a problem engaging it hard on concrete with the 10b axle ,I put on 38.5's and did the same thing,the whole diff shattered into pieces,
That stupid little piece o crap system doesn't have any clutch packs. You saw how chincy the rods and components are that are suppose snap into place when power is applied. Depending on what part of the country you're in snow or mud will tear those up in a heartbeat. Regardless of how one maintains them they will fail at the worst possible moment. I love my Bowtie trucks, but this is the worst system GM ever came up with and sadly they are still using this crap system to the best of my knowledge after many years and people just don' t know about it. I had 3 fail on me with different vehicles and no there aren't any clutch packs in them. I'd love to see the clutch plates make a comeback. My 65 Impala 3 peddle had that clutch plate posi rear never any problems. And yes, on occasion I raced it for fun. I will certainly be putting in a Yukon or other reliable differentials into my wife's Blazer. To GM I say please stop making garbage. I apologize for venting of sort, but this crap system needs to be gotten rid of. and screw these new electronic systems. talk about problems!
Came for the g80, stayed for the chest hair 👍🏻
The chest hair come free of charge

Pretty neat to see the working of the differential, or how it's not working and why. Great video Alex, cheers

Any update on this video on the g80 status? Is there a video of the rebuild?🧐

Awesome to see the insides. 🤙🏻
Want to take the diff cover off but don’t know what I’ll find in there, and don’t want pieces falling out. It’s working now lol.

Realized I had the “g80” code now I want to make sure it’s engaging too
Nice catch brother
I was curious why those fly weights were not spinning and just looked a little closer to find a chunk of gear missing lol. classic G80 locker grenade
@TheGettyAdventures what did you do to fix it? Several on here have asked for an update.
How do you replace spider gears and clutches on this type of diff? Im stuck

That's some disgusting fluid. I do the diffs and xcase 3yr/48xxxkm as fca recommends for frequent towing.
Milky as all hell. and ya, nothing wrong with keeping your fluids nice and fresh. especially on the dodges with those nice drain plugs!
Hey Alex, haven't seen you for a bit, hope you're doing ok.
If you can't get the fill plug off fill it thru the vent tube
brother in a regular 91 chevy 10 bolt the diff lock mechanism fall off you think i can still drive it with out it
Looks like you got some work ahead of you..👍 are those g80
Really special..?? Could the differential just be built with different type..?
no not really I wouldn't call them special. they are nice to have though. and when they are working they work very well.
I mean parts are cheap. for the flyweight assembly its like 130 bucks. whereas a new diff carrier would be like 500-1000 dollars depending on what i wanted
@@GettysGarage wow 😯 ok… well that’s a big difference..
@@mikekosar6135 so hopefully that will fix her up good and then I can throw it around in some mud and snow!
The middle pin on my g80 in my 2001 Tahoe is stuck I can’t get it to come out it’s like stuck but when I turn the diff the pin spins with the diff I’m been struggling trying to hammer it out but nothing
Did u ever get the pin out I’m having the same problem
I need help rebuilding my g80 gov locker... I know a few things about it since I took it off my truck but I don't know how to get it open to replace the gears. I'm too far into this to not finish it myself, just need a little guidance
How did it go did u ever finish
guess this truck got scrapped...no where to be found anymore after this vid!
i have a Chevy 2500 2009 the differential locks up when turning I hear a pop and locks up the rear tires and then I reverse it a few feet and it unlocks any advice on what to do ? might be the Gov lock ?
Any info on the issue?
Have the same problem, I think my right side clutch pack are welded together. These diffs don't like burn outs lol😂.
Where did u find parts?
I spin mine but not even the teeth in the middle spin but the pinion with no bolt spins
I bet that diff was never serviced
These G-80s are innovation for sure, but no, electric lockers controlled by the user should be the norm. I see GM finally did it with the ZR2 Silverado both front and back and this is what should be happening moving forward.
what year is this truck???
Where did you find the clutch packs, and the gear
Chevy or GMC dealer.
Can I place a g80 in my front differential? And what difference would it make?
Nah they don't make that
big confusion- 1st my g80 locker dont work- opened- all parts workin movin - no damage ! so wtf? 2nd confusion have a lim. slip oil tag on diff??
All GM G80's are limited slip differentials
ok so- thers like clutch packs left and right of the diff- thats why to use this lim slip additive?!@@edmundanderson657
My g80 grenaded the carrier housing
Are we just going to ignore the rust?
@lAcid Rainl no sir.
Noticed GM stock has been reflective of there fine manufacturing,,,, "all over the WORLD." It's only a matter of time and they'll go the way of RAMBLER and STUDEABAKER.
One tooth and your sol
Kind of crazy to think about the amount of force that is probably being transferred through those little teeth. but ya pretty much lol
There awesome when they do work,i had 36's and never had a problem engaging it hard on concrete with the 10b axle ,I put on 38.5's and did the same thing,the whole diff shattered into pieces,
had they tend to blow up if abused which is the downside lol honestly kind of lucky just a tooth broke off and didn't take out the whole diff.

Strange, every eaton eaton gov-lock I've served has clutch packs in them. It is a limited slip differential.
