Hi,
I'm not sure what is going on but I have a really bad steering wheel vibration. In fact, I think it's the whole car. It only happens at certain freeway speeds. Also, if the road is brand new pavement it doesn't seem to happen. I don't think it's the quality of the roads either. This happens on a 750 mile stretch of I-5 and FWY 99. Doesn't seem to matter which direction I steer.
I have new tires with great tread. I had an alignment when I got them and if I recall, vibration was still a problem although not as bad. Had the tires rotated -- that helped initially and back to the same problem.
Wondering if they were never aligned properly or something else is wrong? Would a competent tire shop be able to diagnose it?
It's really agitating and not sure what to do about it.
