I've got the G80 in my 08 silverado and at just shy of 23,000 miles, it took a crap on me. Went around a few turns and clunk bang, bing, crunch, squeal... drove fine straight but it felt like the back end was going to fall apart making a turn at speeds above 2 mph. Had it towed to the dealership and they couldn't replicate the problem. They drove it for 25 miles and got nothing abnormal out of it. Good news is now though, the passanger airbag won't deploy without a passenger in the seat.2008 Silverado LT 4.8L V8, 1.5" leveling kit, procomp 18" wheels w/ Nitto terra grappler tires, Magnaflow exhaust, drop-in K&N air filter, Line-X spray on bedliner.

My 2004 Z-71 has the G80, and 3.73's. Makes for a good combo.

Since there is a "fly-weight" that has to sense the speed diff to force the traction lock, it is probably difficult to determine externally and on jacks if it failed. I would drain/remove the diff cover, and look for a ton of broken gear teeth before you get involved with a rebuild shop. I opted to replace mine years ago with a worm drive, as reported here in earlier posts, and it is still going strong in my Duramax

how hard is it to install a g80, obviously there will be some nasty fluid in there but do you need special tools?
