1997 Mercury Sable Q&A
1997 Mercury Sable Question: Car has a loud vibration coming from driver side when between 25-60 mph.
Definitely sounds like a wheel bearing. Probably the driver's side front bearing. Dealer may not have taken it for a test drive and thus, did not discover the problem that would only show under those circumstances. - csubak30
