Hi all, I have a '90 Dynasty with 123K on it. Recently, it has developed a SERIOUS vibration in the driver's side front wheel. It happens at slower speeds, and I noticed it was really bad today at 40 mph. The tire is good and the lug nuts are tight. Could it be the bearing? From what I have read, it looks like changing the hub/bearing is a pain to change. Any info?

 

Could be a bad wheel bearing, but more likely would be a balance issue with the tire, bent rim, broken/seperated belt in the tire. Hit any pot holes or curbs recently?

 

I agree, also try switching the front wheels side to side, if the problem moves to the other side have the balance checked, when this is done the mechanic can tell if the wheel is bent or has a bulge in the tread.
