Came for the g80, stayed for the chest hair 👍🏻

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

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!

Any update on this video on the g80 status?

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.

Awesome to see the insides. 🤙🏻

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

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.

Nice catch brother

guess this truck got scrapped...no where to be found anymore after this vid!

That's some disgusting fluid. I do the diffs and xcase 3yr/48xxxkm as fca recommends for frequent towing.

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

How do you replace spider gears and clutches on this type of diff? Im stuck

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,

Hey Alex, haven't seen you for a bit, hope you're doing ok.

brother in a regular 91 chevy 10 bolt the diff lock mechanism fall off you think i can still drive it with out it

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

Looks like you got some work ahead of you..👍 are those g80 Really special..?? Could the differential just be built with different type..?

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 ?

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

My g80 grenaded the carrier housing

Where did you find the clutch packs, and the gear

Can I place a g80 in my front differential? And what difference would it make?

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??

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.

Are we just going to ignore the rust?

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

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!
