Drive Train Axles Bearings problem
2003 Chevy Avalanche V8 Four Wheel Drive Automatic 100000 miles
Few months ago had what sounded like a rock in the break shield or input shield when I would back up in gear (only while in gear, and only in reverse). Since then the squeak has gone away, but now I have a vibration when driving forward (two events possibly unrelated).
Whole truck vibrates, really noticeable when over 55mph, and even more so when accelerating (the more aggressive the acceleration, the worse the vibration) over 55mph, makes no difference if in drive or neutral, 2wd or 4wd.
Just had new rear tires put on 15,000 miles ago, fronts are little worn 50,000 on those. Camber is out on both fronts, but that has not changed, has always been like that.
Have not hit anything or had any other drive problems. Checked the drive line, u-joints, and everything else I can visually check, nothing really unusual.
My thoughts. Transfer case, input, rear differential, or something as simple as a tire balance.
Any thoughts would help.
