I've noticed my car was making a bit of a clunking noise from what sounded like something in the rear end. I have steeda LCA Relocate Brackets and Billet LCA's, but this clunking has been around prior to that. It usually happens when upshifting or downshifting in lower gears. I find it gets worse after a long trip. If I'm in a lower gear and tap the gas pedal it's very noticeable. After listening to it today I have a feeling it is coming from my driveshaft. If I grab hold of it and twist it there is some play in it(not at the bolts). Is this normal? I want to take it in to my dealer to get it checked out I'm just worried they're are gonna be a pain about the LCA Brackets.

 

why did you put the relocate brackets on? They are usally used on lowered cars. I wonder if they may have slightly messed up your pinion angle

 

I put them on for better traction at the track.

 

It was all done on an aligment rack. The rear end shouldn't have really moved too much. Even if the pinion angle was out a bit I couldn't see it causing a clunk if I tap the gas pedal. It's more like something is loose, I just don't know what.
