Comes from the driver side front wheel. It happens almost without fail when I go from reverse to a stop. If I try to brake slowly and softly I can avoid this pop occasionally. I can also feel the pop through the floor board. This developed after I installed the RC control arm drop brackets.

Its a 4.0 automatic and I have 31's w/ stock gears and a d30 in the front. About 4.5" of lift.

I have ironmanandy's LCA's and I haven't gotten an alignment since i installed the drop brackets so the lcas could be too long causing a bind somewhere? but only in reverse...? Or maybe a bolt is loose somewhere. Just tossing out what ive thought of so far. What do you think?

 

Have you checked the u-joints?

 

I haven't, would that make such a sound? Its just one solid pop/thud. Tomorrow I'm going to try and wiggle everything I can get my hands on to see if anything is loose under there.

 

I forgot, one time when I went over a speed bump at a slow speed it did the same pop. But its only done that once.

 

Only on bumps huh? Maybe check all the bushings. Control arms sway bars make sure your shock is bolted down tight. Just do a check on everything that moves. U-joints make a clunk sound any time the vehicle is driving. Straight corners bump or not. Also check the wheel hub. that could as well have play in it
