Rear passenger knock

I just got a brake job done (both rear pads, spring kit, partial lines) for $250. Today I notice a new knocking around the rear passenger wheel.

The sound can be heard while driving but I can also re create it myself by rocking the jeep by hand. When I stand on the running board and rock it with my body weight, the sound changes locations.

When rocking it by hand not standing on the jeep, it seems to be near the rear passenger wheel.

Is this sound a shock or did my mechanic screw something up? It just started after the brake job, so I'm very suspicious.

Any help would be appreciated.

Can you recreate the knock by push-pulling on the wheel after jacking up the rear axle on one side? If so, you have a Dana 35c rear axle and that that is the normal sound of the axle shaft being able to move in/out which is normal due to its c-clip design.

Check to make sure your lugs are on tight, after that remove the tire and check that everything is tight and bolted in and around the drum etc. lay down and have someone rock the jeep for you. look at sway links, track bar, etc. there are alot of things that could make noise. It may be completely unrelated to the brake job. Also look around for tools that he may have left sitting on top the gas tank or skid plate or something, I have heard of that happening before.

thanks

thanks for your help guys.

with someones help, i was able to get under the jeep while they rocked it.

the rattle was a sway bar bushing. getting a new set today.

I had not thought to look at the sway bar again because i had just welded the other side. turns out it was the sway bar causing trouble yet again!

I appreciate the advice, everyone!
