Clearance Issues
 

I just recently put on on Eibach Springs and Bilstein Shocks and for the first week it drove awesome. Now I just come back tonight and as I was entering town every time I hit a bump I would here a pounding. What would all of a sudden just start this? I checked underneath and everything is in the same place, nothing came out. It only happens when I move the car back and forth or over a bump, but not side to side. Could it possibly be the over axle pipe? I would think it would have been hitting this whole time if that was the case?

Over the axle pipe as in exhaust pipe.

did you hear a pounding from the rear or the front?.......did you also install a pan-hard bar when you lowered your car?......are you sure your rearend is centered?

It's getting aligned this week. I didn't install anything but the springs and shocks. My uncle said since it wasn't lowered to drastically that the rearend being not centered really wouldn't be an issue, but I guess it might. It's just odd how this sound started after about 100 miles of driving.
