Like many others I have been fighting a front end vibration since I purchased my Seville. Right now I do not have new tires but they are properly balanced. The vibration is there with both my summer and winter rims/tires. I usually do the Road Force when I get them balanced. I noticed the other day that I really feel the vibration through the steering wheel; it is constant when traveling above 50 mph.
This past week I replaced the swaybar, tie rods, and the front left wheel bearing. I didn't replace the right bearing as my mechanic didn't notice a problem with it. Any ideas what it could be?
