At lunch today, I hit a pretty substantial dip in the road, got my normal rubbing up front, but then when my rear wheels hit the dip, I heard a small "Clank" from the right rear. Got to back to work, and noticed now my right rear is sitting about 1/2 inch lower than before. I am running on Ground Controls with Koni yellow's. Any ideas, while I sit here at work anxiously waiting to get home and jack up the car. My first guess was something came loose. I am praying for the best, and getting ready for the worse. Dont see how the ground controls could of caused the change, unless the shock blew or the collar moved, but I hope the lower or upper control arm did not bend!!!
