I have a squeal coming from the rear end on acceleration. It's noticeable from start until about 30 mph. A friend mentioned it sounded like it was coming from the left rear so I checked and noticed some oil around both hubs. So I changed the rear axel seals. The problem is still there. Any idea's?
Did you degrease the shoes and drum after repairing the seals?

Is it a constant squeal or a pulsing squeal? If it's a pulsing squeal, does it speed up and slow down with road speed?
Doc
Sounds like it might be your u-joints. Hop under the truck and grab the driveshaft as close to the u-joint as possible and start jerking it around every which way and see if you can duplicate the squeak.
Another thing to try would be to secure the truck's rearend on jackstands, fire her up, put it in D and follow the noise.
