about a week ago i hit a pothole with my rear passenger wheel about 30mph..after i hit the pothole i notice a knocking coming from the rear passenger wheel only when i made a right turn, i went back home and i checked the wheel and i had a flat tire..so i assumed that knocking was because i was driving with a flat tire..next day i replaced the rim with the 16" mp5 stock rim(currently i have aftermarket 17") i drove with the stock rim for about 3 days and i had no knocking problem, so today i went and bought a new tire for my 17" rim and i installed the rim back into my car and the knocking problem came back and that only happens when i turn to my right...does some one know whats the problem??
