Volkswagen Passat W8 Problem
Visitor, 2003 Volkswagen Passat W8, 130,000 mi
I have a high speed vibration at speeds over 65-70 mph? I've had 4 wheel alignments twice in the last few months. Took it to the shop and they said the tires were cupped?! The vibration is a little better, but its still noticable. Could this be a suspension problem?
