After changing left front wheel bearing and cv transaxle I have a vibration that intensifies at higher speeds. It feels like a bad belt in a tire. I've rotated tires and the tires only have 1500 miles on them. Any ideas whether its an alignment issue or maybe a bad bearing in the transmission where the transaxle slides in? I don't think I had this issue prior to changing out the wheel bearing or transaxle. I have 168,000 mile on this car and it still going strong. Runs great, accept for this front end issue.
