NOTE: Inspect the bearing surface on the drive shaft where the needles of the lower pin-

ion bearing roll. The condition of the drive shaft at this location gives an indication of the

condition of the needle bearing. Replace lower pinion bearing (needles and race as a set)

if the drive shaft is pitted, grooved scored, worn unevenly, discolored from overheating,

or has embedded particles.

IMPORTANT: All the needle bearings (18) MUST BE in place inside bearing race

while driving the pinion bearing from the gear housing.

IMPORTANT: Do not reuse the bearing (race or rollers) once it has been removed.

1. Remove and discard the pinion bearing (race and rollers) using tools as shown.
