2.
Temporarily install pinion height adjusting washer (1).
When hypoid gear set has been replaced
• Select pinion height adjusting washer. Refer to
.
When hypoid gear set has been reused
• Temporarily install the removed pinion height adjusting washer
or same thickness washer to drive pinion.
3.
Install selected pinion height adjusting washer (2) to drive pin-
ion. Press pinion rear bearing inner race (1) to it, using drift (A)
[SST: ST30032000 (J-26010-01)].
CAUTION:
• Pay attention to the direction of pinion height adjusting
washer. (Assemble as shown in the figure.)
• Never reuse pinion rear bearing inner race.
4.
Temporarily assemble removed drive pinion adjusting washer
and drive pinion bearing adjusting washer or same thickness
them to drive pinion.
5.
Apply gear oil to pinion rear bearing, and assemble drive pinion
into gear carrier.
6.
Apply gear oil to pinion front bearing, and assemble pinion front
bearing inner race to drive pinion assembly.
CAUTION:
Never reuse pinion front bearing inner race.
7.
Using suitable spacer (A), press the pinion front bearing inner
race to drive pinion as far as drive pinion nut can be tightened.
8.
Adjust pinion bearing preload. If necessary, select the appropri-
ate drive pinion adjusting washer and drive pinion bearing
adjusting washer. Refer to
.
9.
Using the drifts, install front oil seal as shown in figure.
CAUTION:
• Never reuse oil seal.
• When installing, never incline oil seal.
• Apply multi-purpose grease onto oil seal lips, and gear oil
onto the circumference of oil seal.

DRIVE PINION
10. Install companion flange (1).
NOTE:
When reusing drive pinion, align the matching mark (B) of drive
pinion with the matching mark (A) of companion flange, and then
install companion flange (1).
11. Apply anti-corrosion oil to the thread and seat of new drive pin-
ion lock nut, and temporarily tighten drive pinion lock nut to drive
pinion.
CAUTION:
Never reuse drive pinion lock nut.
12. Tighten to drive pinion lock nut, while adjust pinion bearing pre-
load torque.
CAUTION:
• Adjust to the lower limit of the drive pinion lock nut tight-
ening torque first.
• After adjustment, rotate drive pinion back and forth 2 to 3
times to check for unusual noise, rotation malfunction,
and other malfunctions.
13. Install differential case assembly. Refer to
CAUTION:
Never install carrier cover yet.
14. Check and adjust drive gear runout, tooth contact, drive gear to drive pinion backlash, and companion
flange runout. Refer to
Recheck above items. Readjust the above description, if necessary.
15. Check total preload torque. Refer to
.
16. Install carrier cover. Refer to
.

2.
Select the proper pinion height adjusting washer.
If impossible find the desired thickness of washer, use washer with thickness closest to the calculated
value.
PINION BEARING PRELOAD
• Assemble the drive pinion parts if they are disassembled. Refer to
1.
Make sure all parts are clean. Also, make sure the bearings are well lubricated with gear oil.
2.
Install companion flange (1).
NOTE:
When reusing drive pinion, align the matching mark (B) of drive
