i just installed my eibach pro-kit and kyb agx and in the rear im getting a strange sound from the passenger side. i haven't done the alignment and im trying to figure it out. when i hit a bump i can hear something rattle, sounds like something is loose. i took the suspension completely off of the car and made sure everything was tight. after reinstalling it and driving i still notice the sound there. there is nothing loose. has this happened to anyone before, or is this just normal since the car bottoms out earlier? thanks.
