b. Adjust the drive pinion preload by tightening the companion flange nut.
HINT:
Tighten the nut using approximately 98 N.m (1,000 kgf.cm) of force and then tighten it further
while observing the preload. Using SST to hold the flange, tighten the nut.

c. Using SST and a torque wrench, measure the preload.
Drive pinion preload (at starting):
New bearing:
1.5 to 2.0 N.m (15 to 21 kgf.cm, 13 to 18 in..lbf)
Reused bearing:
0.5 to 0.8 N.m (5 to 8 kgf.cm, 4.3 to 6.9 in..lbf)
HINT:
Do not apply hypoid gear oil if a new bearing is used.
Turn the bearing clockwise and counterclockwise several times to stabilize the bearing,
and then measure the backlash.
If the preload is not within the specification, adjust the rear differential drive pinion
preload or repair as necessar
y.

INSTALL REAR DIFFERENTIAL CASE BEARING
a. Using SST and a hammer, install the drive pinion side outer race.
SST 09608-32010, 09950-70010 (09951-07200)
HINT:
Tap in the outer race until half of the side gear shaft snap ring groove of the differential
carrier can be seen.

INSTALL REAR DIFFERENTIAL SIDE GEAR SHAFT SNAP RING
HINT:
This procedure is required only when final gear set (drive pinion & ring gear) is replaced.
a. Using snap ring pliers, install the thinnest side gear shaft snap ring on the ring gear
side.
