steering wheel shakes/vibrates over 60mph
This is one of the few problems with my car id like to address as i continue to fix up my car. I have an 03 ZX3. i have had this issue as long as i can remember owning the car which has been almost 2 years. While driving on the highway over 60mph my steering wheel vibrates and shakes quite a bit. I have already had new tires, all balanced, new wheel bearings, alignment and all 3 mounts replaced and it still does it.. ive also looked for answers online a while ago and could never figure it out. the mechanics could never find out whats wrong cuz they never went over 60mph in it.. im still confused on what exactly it could be. there is nothing wrong with my car part wise that the mechanics know of.. anyone have this happen to this to them or know what the problem may be?
