Acckk!! The Avalanche needs some love!
Took the truck into the dealer on Friday. All winter long I’ve been hearing a sort of grinding noise coming from somewhere underneath the truck (sort of sounds like the rear diff) and it’s progressively gotten worse and worse. The tech and I took it for a drive around the lot and he heard it right away, but said it was the driver’s side wheel hub. Ok, no prob… fix away.
I call them around 3:30pm because I haven’t heard anything back yet and the guy tells me, “We were just talking about you.” Whenever the dealer says that to you on the phone it can’t be good. He said the techs had the truck up on the lift and “heard noises coming from all over the place”.
The rear wheel backing plates, which seemingly don’t really do anything, were completely rotted away and were one source of noise. They need to be replaced. Another sort of rattling noise is coming from the rear wheels… this time it’s the left rear parking brake. The lining had seperated from the shoe. Replace that. Oh, and your pads are really low so they’ll need to be replaced and the rotors resurfaced. And finally… we come back to the rear differential. Needs an overhaul. Case and axle bearings were shot. The axle shafts definitely show wear, but an axle bearing repair kit can be installed to elliminate having to replace the axle – oh thanks. Heck, while it’s up on the lift you guys might as well flush the tranny for me and refill her with some new fluid.
Grand total: $2,309.16
Fun!

I understand your situation! Recently pulled my 02 Avy out of the driveway. When I put it in drive, it initially acted like it didn’t want to move! Once it got rolling everything seemed to be fine. But then….just as I thought it might have been my imaginination, clunking noises starting coming from the rear end. I thought it was the rear diff going out so I took it in for an assessment……………………………
