i clipped my weel on the curb the other day doing about 30mph, now when i drive on the motorway or exceed 50 my front end,steering weel and gearstick wobble like hell...ive had all the weels balanced and the tracking done but its still there..the control arms arnt bent so im guesing its a bent rim even tho there are no signs or tell tale marks that ive hit the rim ...any other ideas what it all could be ?
