Agreed. Check your rear sway bar and all control arm bushings. You could just have a split CA bushing or a loose bolt that allows some play. Can make a clunk sound when stepping on the gas torques the axle.
If that isn't it, then start checking for loose/worn u-joints, pull the diff cover to check gears, etc.
