(1) With the beveled (large) part of the rear wheel oil pump
drive gear at the inner side, press in the drive gear (by
using the special tool) until the drive gear contacts theend surface of the
.differential case.
(2) Check to ensure that the drive gear and the spring pin
are flush.4. INSTALLATION OF DRIVE PINION REAR BEARING
OUTER RACE
/ 5. DRIVE PINION FRONT BEARING
OUTER RACE
Press-fit the drive pinion rear and front bearing outer racesinto the gear carrier by using the special tools.
CautionBe careful not to press in the outer race at an angle.
. DRIVE PINION HEIGHT ADJUSTMENT
Adjust the drive pinion height by the following procedures:
(1) Install special tools and drive pinion front and rear
bearing inner races on the gear carrier in the sequenceshown in the illustration.
NOTE
Apply a thin coat of multipurpose grease to the matingface of the washer of the special tool.
(2) Tighten the handle of the special tool until the standardvalue of drive pinion rotation torque is obtained.
(3) Measure the drive pinion rotation torque (without the oil
seal).

(1) Gradually tighten the nut of the special tool while checkingthe drive pinion rotation torque.
(2) Because the special tool cannot be turned one turn, turn it
several times within the range that it can be turned; then,after fitting to the bearing, measure the rotation torque.

TIRE INFLATION PRESSURE CHECKM3lFDA.E
Check the inflation pressure of the tires. If it is not within the
standard value, make the necessary adjustment.
TIRE WEAR CHECKMJlFBAC
Measure the tread depth of tires.
Limit: 1.6 mm
(.06 in.)
If the remaining tread depth is less than the limit, replace the
tire.
NOTE
When the tread depth of tire is reduced to 1.6 mm (.06 in.) orless, wear indicator will appear.
WHEEL RUNOUT CHECKM31 FCAEJack up the vehicle so that the wheels are clear of the floor.
While slowly turning the wheel, measure wheel runout with a
dial indicator.
