hello everybody cool site,well the question i have is i have a corolla 1.4 04....i seem to be hearing clicking sounds coming from my wheels alot it seems to change wheels i think it coming from two wheels so i decided to take the wheels off to see what it was everything looked ok no stones or anything in the wheels.but then i happened to just move the rotor/brake disc and it seems a bit loose it moves back and forward a bit should it be like the other wheel is not like that and if it not supposed to be like that how would i tightening it.the wheel seems to grind abit when i spin the wheel jacked up only on half the disc so it grinds half way around the disc and than the other half is fine no grind any ideas what that would be.........
