I install my bc coilovers like 3weeks ago by the way the car runs nice and 0 body roll. So now am getting this noise in the rear like if there was something lose first I thogut that my books in the trunck was making that noise over bumpy road but no it's the rear passenger side I still haven't gotten a panahard bar can it be that the differential is hit the chasie of the car?? Has anyone had this problem?? I check everything and it's all install rite and tight ?? It's really annoying
