I'm having an issue with my wife's 2008 Camry. We're feeling vibration at highway speeds. Feels like it's coming from the front passenger side. We've had all 4 tires replaced (two of them replaced twice because we got lucky and the shop gave us a set of 4 for free with all the trouble we were having with the goodyear tires they sold us), and added hub-centric rings to her wheels. There are no noises to tell me whether it's a cv axle or a bearing. I've been under the car and the only thing I can find that comes close to loose is that the passenger side axle has just a little more side to side play (runout - inner cv) than the driver's side. Any suggestions?
