Hi, I have a 94 Nissan Pathfinder v6 4x4 3.0 sometimes when I would hit the brakes and the truck rocks forward and settles back I would here a thumping sound as it rocks backward. Some times it would happen accelorating too.

Not sure what this might be Bushings? or other inner workings that I am not sure what they do. Also I am almost certain that the right side of the truck leans slightly. The rear brakes have not been changes on this truck sinse I bought it in 94, could the brake be causing this?
