Final Drive Pinion Bearing
Some Rivieras may experience a final drive noise and/or loss of drive due to an overheated final drive pinion bearing. A preliminary sign of this
condition could be a loss of upshifts due to a worn governor gear in the transmission (appearing to be "apple cored," refer to illustration). Therefore, the
final drive pinion bearings should also be replaced at this time.
