1995 K2500 Rear End noises

[Saltlife228]

Hi I bought a 1995 k2500 sheyenne. There is a rather loud high pitch grinding/ squeaking noise emitting from what I would say the rear right of the truck. I have completely replaced the brake shoes and new pins and springs. No luck. What I can say is:
1. It hardly gets any louder as I speed up.
2. Still screams when in neutral, as long as the truck is rolling.
3. Rear differential has plenty of fresh fluid when I bought it.
4. If i hit a good size bump, it will run quiet for about 15 seconds.


ANY ideas before I go tearing into bearings and rear diff?

I would put the rear end up on jackstands or something equivalent. Put it in gear and walk around the truck. But do it safely.

the rear wheel bearing are most likely worn. check these for axle movement..

Well, since you narrowed out the brakes, the only thing I could really think of would be the wheel bearings.
