I did some search and read about multiple causes of this. I had to make about a 80 mile round trip yesterday on the highway running about 70 mph and I noticed a vibration. It seems worse when I accelerate which I guess is a sign of a bad cv axle ? The car has new front tires so that shouldn't be causing the problem. I can see the pass seat shake as im driving down the highway. The rear tires could use replacing as well. I was planning on jacking it up today and checking the rear bearings. Any ideas on where else to look ?
