I replaced the tires and it helped but it didn't fix all of the vibration. I found evidence of grease loss around the front CV joints but i am not hearing the loud clunk when turning that is associated with CV joint failures . Does this sound like a wheel bearing problem ?I am not getting any codes from the on board computer or my OBD2 scanner. The X5 has 96500 miles on it and is a very clean car.Are there any special tools needed to replace the CV axles ? Thanks.
