I've been hearing a noise coming from the back of the truck by the left rear wheel. I have checked the brakes and the wheel but the wheel does not seem to be bent. Is it the rear differential

I have a noise that sounds like a snapping metal to metal in my passenger rear wheel i haven't fixed it cause i Dont know where to start.
Is it in my tranfer case or the front or rear axle, to me it seems the four wheel drive chain has to much slack in it is there an adjustment? I notice it more when I come to a quick stop after realseing the brake pedal I get a loud thumping sound as if one thing caught up to another.

If your experiencing a loud clunking sound when stepping on the gas from a dead stop or when just rolling and stepping on the gas It's not the front or rear differential, it's the rear out put shaft of the 4 wheel drive. I have had this same problem on my 1999 Tahoe and on my 2002 Blazer. Replace the transfer case and the noise is GONE!! If it's a rumbling sound at the rear wheel it could jut be a bad axle bearing.

Rear end started making a growling sound; also a noise started coming from front wheels when press on gas; Chevy Service center said is transfer case & front differential & that problem developed from car being driven in Auto 4WD - has worn out bearings, ring & pinion. EXPENSIVE fix.
