1. Remove electric controlled couplings. Refer to
.
2. Remove center stem assembly. Refer to
3. Remove drive pinion lock nut with the flange wrench (A) (Com-
mercial service tool).
4. Put matching mark (A) on the end of drive pinion. The matching
mark should be in line with the matching mark (B) on companion
flange (1).
CAUTION:
For matching mark, use paint. Never damage companion
flange and drive pinion.
NOTE:
The matching mark on the final drive companion flange indicates
the maximum vertical runout position.
When replacing companion flange, matching mark is not neces-
sary.
5. Remove companion flange using the puller (A) (Commercial ser-
vice tool).
6. Press drive pinion assembly out of gear carrier.
CAUTION:
Never drop drive pinion assembly.
7. Remove front oil seal.
8. Remove inner race of pinion bearing (front).
9. Remove collapsible spacer.
: Apply anti-corrosive oil.
: Apply Genuine Silicone RTV or equivalent. Refer to

3. Temporarily install drive pinion adjusting shim (1).
When hypoid gear set has been replaced
• Select drive pinion adjusting shim. Refer to
.
When hypoid gear set has been reused
• Temporarily install the removed drive pinion adjusting shim or
same thickness shim to drive pinion.
CAUTION:
Pay attention to the direction of drive pinion adjusting
shim. (Assemble as shown in the figure.)
4. Install inner race of pinion bearing (rear) (1) to drive pinion with
the drift (A) [SST: ST33032000 (
—
)].
CAUTION:
Never reuse pinion bearing.
5. Assemble collapsible spacer (1) to drive pinion (2).
CAUTION:
• Be careful of the mounting direction of collapsible spacer.
• Never reuse collapsible spacer.
6. Assemble drive pinion into gear carrier.
CAUTION:
Apply gear oil to pinion bearing.
7. Assemble inner race of pinion bearing (front) to drive pinion
assembly.
CAUTION:
• Never reuse pinion bearing.
• Apply gear oil to pinion bearing.
8. Using the drift (A) [SST: KV37710000 (
—
)], press the
inner race of pinion bearing (front) to drive pinion as far as drive
pinion nut can be tightened.
9. Using the drift (A) (Commercial service tool), drive front oil seal
until it becomes flush with the gear carrier end.
CAUTION:
• Never reuse oil seal.
• When installing, never incline oil seal.
• Apply multi-purpose grease onto oil seal lips, and gear oil

DRIVE PINION
10. Install companion flange.
NOTE:
When reusing drive pinion, align the matching mark (A) of drive
pinion with the matching mark (B) of companion flange (1), and
then install companion flange.
11. Apply anti-corrosion oil to the thread and seat of drive pinion
lock nut, and temporarily tighten drive pinion lock nut to drive
pinion, using the flange wrench (Commercial service tool).
CAUTION:
Never reuse drive pinion lock nut.
12. Adjust to the drive pinion lock nut tightening torque and pinion
bearing preload torque, using the preload gauge (A) [SST:
ST3127S000 (J-25765-A)].
CAUTION:
• Adjust to the lower limit of the drive pinion lock nut tight-
ening torque first.
• If the preload torque exceeds the specified value, replace
collapsible spacer and tighten it again to adjust. Never
loosen drive pinion lock nut to adjust the preload torque.
• After adjustment, rotate drive pinion back and forth 2 to 3
times to check for unusual noise, rotation malfunction,
and other malfunctions.
13. Install center stem assembly. Refer to
.
CAUTION:
Never install rear cover at this timing.
14. Check and adjust drive gear runout, tooth contact, drive gear to drive pinion backlash, and companion
flange runout. Refer to
15. Check total preload torque. Refer to
.
16. Install rear cover. Refer to
17. Install electric controlled couplings. Refer to
