My P85 MS has aftermarket lowering links for the air suspension and the car sits about 1" lower than the factory low setting when at standard. I have aftermarket 22" ADV1 wheels as well. I have noticed a mild vibration from the rear under hard acceleration at freeway speeds. I took my car in for service and the service advisor thinks the lowering links have caused stress on the drive shafts; they noticed excessive play at the right rear CV joint. They want to replace the rear drive shaft for about $1800. They state that the lowering links voided the warranty for this issue. Has anyone had similar issues or does this make sense? I am thinking about holding off on the repair since the vibration is very mild.
