Just put on new wheels. 19*8F & 19*10R..........First problem i had was the lugnuts were to long on the rear wheels. made a noise from the parking brake in the rear hubs..... solved that with shorter lugnuts. but now i hear a clanking/ knocking noise whenever i reverse the car, sounds like its coming from the rear...........any ideas what the noise could be? driving is fine, no noise...... I have a 2005kss.........
