Help Diagnosing Problem

When I go over bumps, there is a weird noise from my passenger rear wheel well. It sounds like something is loose. I checked evrything, and made sure that It was tight, and it still does it. It is not over every bump, just some, and its really annoying. I am thinking it could possibly be the rear upper control arm ball joint has gone bad. Has anyone had that gone bad, and can confirm its this.

Thanks

Is the car lowered?

yeah, im dropped about 1-2inches right now...its not that anything is hitting either. It just sounds like something is loose and wiggling around.

Well if it happens when you are going over bumps it could be that the shock is extending past the maximum stretch of the lowering spring so you get a "clank" type of sound.

If you go over the speed bumps slowly does it still make any noise?

I dont think it does it when i go slow. Could be wrong though... and it only does it on the passenger side.

I have the tokico coilover set if that makes any difference.

My car makes that noise in the front though. It pisses me off. It the controll arm I think. Ive replaced every thing else but I dont want to spend the 70 (i think?) for the part now!
