Hi everyone,
Haven't been on the site for a while, recently I have only been using the truck as a back up and it has been doing pretty well.
I have a '98 K3500 Dually with about 215,000 miles.
I picked up a vibration and I am pretty sure it is the rear end and I was wondering if anyone else had experienced it and if so, how it was fixed.
What I have done:
The only thing I have seen that looks odd (other than the vibration) is when I shift from Drive to reverse and back again, the drive shaft seems to make a least one complete revolution without turning the wheels and about half the time there is a loud clunk that I never heard when the truck is on the ground.
Appreciate any help you can give me.

What I have done:
- New tires and balance - no change
- Put it on jack stands (on the frame) ran it at 35 mph - definite vibration in the rear
- Removed the wheels - still vibrates
- Removed the drums and axles - no vibration
- Removed the differential cover - nothing looked unusual, no visible broken teeth and no pieces or parts in the bottom
- Ran the truck at idle in drive with one axle and drum installed and I could see a rhythmic vibration on the ring gear.
- Nothing other than the rear end seems to be vibrating - Transmission, transfer case, drive shaft...all seem fine.
