I recently put eibach lower springs and a whiteline rear sway bar and endlinks. I have noticed alot of rattling coming from the rear of the car. At first I though it was stuff I had in the truck but I removed all the stuff I had in there. I check all the bolts and everything is tight. Also have kept an eye on the endlinks since people seem to have issues with those. Again everything is tight and looks fine.

Any ideas or any one else experiencing this after putting similar parts on their car.

Thanks
