Diagnosis help

Not all the time, but I am hearing a tinny rattle during acceleration from under my blazer. Sounds like a squeaky bed...hard to describe. Friend thinks bad U joint in the rear. I know it's not a lot of info but would a bad U joint make that metal-on-metal noise during acceleration? Quiets down when up to speed.
