Put the truck on a rack, check the rear end fluid. You should be able to touch it with your little finger in the hole. After you get some fluid on your finger rub that finger and another together see if there is any gritty feeling, the rear diferental fluid lubricates the bearings. If the fluid is low add correct differntal fluid, the rear bearing could be going bad.
