: the contact stated that an independent mechanic determined while servicing the vehicle that there was a premature failure in the pinion bearings and the carrier bearings from the rear end of the vehicle. Updated 7/13/2006 - the differential unit started making noise. The vehicle was taken to an independent repair facility and told that the carrier bearing and pinion bearing and the races for both were pitted and had black streaks on them.
