48.
Rotate housing (3) 90 degrees. Lubricate rear pinion bearing (6) with lubricating oil.
CAUTION
Spacer sleeve controls pinion bearing preload. Do not reuse old
spacer or pinion bearing damage may result.
49.
Install spacer sleeve (8) on pinion gear (7) and install pinion gear (7) in housing (3).
50.
Install pinion yoke (9) and dirt deflector (8.1) with locknut (10) on pinion gear (7).
CAUTION
Do not exceed specified preload torque on pinion bearings. Do not
loosen locknut to replace preload torque or pinion bearing damage
may result. If specified torque is exceeded, remove pinion gear
and replace collapsible spacer and locknut and adjust preload
again.
51.
Tighten locknut (10) only enough to remove end play and seat pinion bearings in housing (3).
Rotate pinion yoke (9) while tightening, to seat bearings evenly.
52.
Measure torque required to rotate pinion gear (7). Correct pinion bearing preload torque is
