(1) If the oil seal is to be replaced because of damage, driveit in by using the special tool.
(2) Apply the specified grease to the oil seal lip.
2. INSTALLATION OF DRIVE SHAFT
CautionI.
Be cautious to ensure that the differential carrier oilseal is not damaged by the drive shaft spline.
2. The right drive shaft for models equipped with the
LSD having a VCU has a two-part serration. Be verycareful to install each one on the correct side.
NOTE
The left and right drive shafts can also be distinguished
from each other by the identification color of boot band

CautionBe sure to thoroughly remove any oil or grease, etc.
from the threaded part of the bolt and nut used for
installation to the companion flange, because any oil,
grease, etc. on these parts might cause later looseningeven though tightening is at the specified torque.

torque.@ Start the engine and depress and hold the brake pedal
for five seconds.@ Stop the engine. (Approx. 200 N
[44 Ibs.])@ Rotate the brake disc ten turns in the forward direction.@ Using a spring balance, check the brake drag force.
9. If the difference between the brake drag force and hub
rotating force exceeds the standard value, disassemble the
piston and check the piston sliding surfaces for dirt and
rust, piston seal for deterioration, and lock pin and guide pin
for sliding motion.
Standard value: 70 N (15.4 Ibs.)
