99 Integra LS auto Well, I've replaced the passenger axle twice already. New Tires Alignment seems to be ok When I have the car jacked up and in D4, and accelerate the shaft of the CV wobbles slightly. It is not out of round. There appears to be some play on the inboard join, but not between the joint and axle. There is a groaning sound when the car is in drive (not reverse) and I accelerate. The symptoms that I have been having include: groaning sound when accelerating (like wheel bearings, but when I checked the bearings with the simple test for movement they seem rock solid) Upon initial accleration there is a rough vibration that goes away after I gain some momentum So does this sound like it might be a bad diff or something else?
