Hi it is possible a shock mounting is loose,sometimes when a vehicle is raised,the suspension is hanging and you can see or feel the looseness.A would also take a good look at the rear wheel caliper and pads,the could be some looseness there and going over a bump would give yo the noise. If the truck has a rear stabilizer bar,the bushings and links need to be inspected.Last though it may sound simple ,check the mounting of the spare tire ,they can give you a noise if not mounted tight.

I put new shooks on also we checked the springs. it seems like it is in the wheel or axle and just on the drivers side.it is driveing me nuts. spare tire is tight
Expert:  roadsidejerry replied 6 years ago.

Has the up and down play in therear axle been checked.The axle rides on a bearing in the end of the axle tube. I have had some that the bearing started to fail,and the axle shaft had to be replaced,since the axle shaft acts as the inner bearing race on that design.The rear rotors also have the parrkng brake shoe inside,I have not had a problem with one, but it is possible they can be giving you the noise if there is a problem with them.here are some illustrations of the park brake and axle.
