Hi guys !! I have a little problem with my gbody. When I drive at low speed (under 20mph), I can feel the rear of the car swinging left-right. When I drive on a pothole (there are a lot here !), the rear swings left-right too and It doesn't feel really safe.. I was thinking that it could be the shock absorbers ? I have a pair of brand new rear air shock absorber, maybe I should try them. What could it be ? thanks !
