Hey I have an 89 civic 4door LX 1.5L and for the past six months whenever I make a turn My car squeaks or if I hit a pot hole it sounds like my wheel hops. The dealer told me that it was a ball joint in the upper control arm that is causing all the noise and hopping. Is there any other factor that could attribute to this noise and hopping? And when I have the wheel turned all the way either left or right there is this kinda grinding noise. I have replaced both axles and springs. HELP!!!
