G80 finally went!
More carnage on the trail the other day. Hit a technical section that I had no business being on, technical rock crawling section that does not favor long wheelbases. The rocks were big and fun, I had plenty of clearance, however on the last obstacle passenger rear wheel spun, locked and I heard a snap as I crawled up the rock ledge. I drove enough out of the way for my buddy to get up the ledge, which he did due to the short wheelbase of the Jeep and I inspected the damage.
Ok the rear sway bar connecting link popped off again, no problems, been there done that. So I put the truck back in 2wd and continued driving. However I started to hear clicking and clunking coming from my rear end. My first thought was that I snapped an axle. I stopped again, jacked up the rear end and both axles were still in tact. I put the Sub in 4wd high and continued the rest of the way, 28 miles of trail to the pavement. Clicking and clunking was gone when the truck was driving straight, however anytime I turned it cam back louder and louder every time.
I babied the Sub all the way to the pavement in 4wd high or low where I would usually be in 2wd high. It was a nerve wrecking and long drive in 112 degree heat. Eventually I got to the pavement and the clunking was completely gone in 4wd high in a straight line and in minor turns. I drove it another 90miles back home with no issues until I got off the highway 1/4 mile from my house. I had to make 3 right hand turns in the residential neighborhood and the clicking and clunking turned into crushing and crunching as I pulled up to my driveway, which I was able to barely make into in reverse, all 30ft of it.
Couple chunks of metal fell out when I cracked the diff cover to drain the fluid the following morning. My heart almost skipped a beat especially I had to go back to work in two days.
This is what the carrier looked like after I spent nearly half an hour hammering and grinding the carrier body to pull the ring gear off.
The G80 locking mechanism looks like it held up pretty good and that's the only part that did.
Managed to crack the carrier body. I also bent the big pin that keep the planetary gears locked in too but didn't get a picture of it.
Missing a couple teeth here.
Missing a couple more on this side too.
So everyone was absolutely right, G80 sucks, its a terrible differential and just randomly blows up on you if you look at it wrong. In reality I can pick one up on eBay for $100. It lasted over 250,000 miles in the truck, 150,000 miles as long as I owned it. Previous owner pulled a two horse trailer with it, I pulled a 12,000 pound boat up and down 5,000-6,000ft passes to California and back for a summer. It put up with my driving: blasting through the desert at trophy truck speeds for over a year turning 37" tires. I crawled along side $70k specialty built Jeeps. And it did all that for 18 years!!!!
RIP G80 you will be missed. Off road community hates you because you are cheap and work better and last longer than any air or electric locker. 144 times longer in my case. And everyone that blew $1,000 or more to put an air or elocker in their rigs is jealous that the G80 is not available for their trucks at 1/10th the the price, LOL.
I am at a cross roads now, I picked up another G80 on eBay over a year ago for $75 that has been sitting on the shelf collecting dust waiting for this one to go, and I also acquired a 8.5" Detroit locker from a Camaro drag racer who upgraded to a Corvette and sold off all the unused parts.
Stay tuned for more shenanigans!
