Have you made sure the rear diff. has the proper amount of fluid in it? I had the same symptoms, it turned out my rear diff fluid was low, refilling it solved the issue. All you have to do to check the level is pull off the rubber plug on the diff cover, the oil should be level with the bottom of the hole. You may in fact need a new pinion bearing, but diff fluid is easy enough to check. I second Kolak for the part if you do need it, I've never heard of someone having a bad experience with him, and his parts seem to be the least expensive of anywhere you can get them.
