Out of the blue our 2002 Grand Prix GT(102k) decided to start making a growling/vibration. It seems to be road speed related to the pitch. It dosent change with rpm, acceleration or braking. I checked the tires and rotated them, no change. I replaced the hub assemblies, no change. Finally I changed the cv axels, still no change. The trans. shifts smooth with no slipping, but I fear there being a problem in the differential or shaft bearings. The drivers side is solid, but the pass. side has some lateral movement. Oddly enough there is no leakage around the inboard end of either cv. Any sugestions or tips on repair without removing the trans. would be greatly appreciated.
