on my 95 Camaro z28 my rear pan hard rod bushings were frozen and my car was leaning to once side so i took it out greased them up and put it back in and i was fine. this was like a month ago now when i drive when i hit the gas lightly i hear dunk dunk dunk. and its worse when i make right turns. i think its something to do with the bushings in the rear but not possitive does anyone know how much a rear bushings set is or any other ideas what it could be
