5. Remove companion flange from drive pinion with a puller (A).


5. Remove companion flange from drive pinion with a puller (A).

6. Remove drive pinion oil seal from the transfer case with a puller


6. Remove drive pinion oil seal from the transfer case with a puller (A) (SST: KV381054S0).

CAUTION:
Never damage transfer case.

7. Remove drive pinion assembly (1) from transfer case while tapping


7. Remove drive pinion assembly (1) from transfer case while tapping the drive pinion lightly with a plastic hammer.

CAUTION:
Never drop the drive pinion assembly.

8. Remove collapsible spacer from the drive pinion.

9. Remove inner race of drive pinion bearing (rear side) from transfer case.

10. Remove inner race of drive pinion bearing (front side) from drive


10. Remove inner race of drive pinion bearing (front side) from drive pinion with a replacer (A) (commercial service tool).

11. Remove drive pinion adjusting shim from the drive pinion.

12. Perform inspection after disassembly. Refer to DLN-111, "Inspection".

Assembly


Assembly

1. Select drive pinion adjusting shim. Refer to DLN-98, "Adjustment".

2. Install selected drive pinion adjusting shim to drive pinion.

3. Install inner race of drive pinion bearing (front side) to drive pinion with a drift (A) (SST: ST35272000).

CAUTION:
Never reuse drive pinion bearing (front side).

Apply gear oil to the drive pinion bearing (front side).

4. Assemble the inner race of drive pinion bearing (rear side) into the transfer case.

CAUTION:
Never reuse drive pinion bearing (rear side).

Apply gear oil to the drive pinion bearing (rear side).

5. Install drive pinion oil seal to transfer case with drifts so that it


5. Install drive pinion oil seal to transfer case with drifts so that it becomes flush with case end surface with the drifts (A and B).

A : Drift (SST: KV38102510) B : Drift (SST: ST30720000)

CAUTION:
Never reuse oil seal.

Apply multi-purpose grease onto oil seal lips, and gear oil onto the circumference.

6. Assemble a collapsible spacer onto the drive pinion.


6. Assemble a collapsible spacer onto the drive pinion.

CAUTION:
Never reuse the collapsible spacer.

7. Assemble drive pinion assembly into the transfer case, and then install companion flange (1) to drive pinion.

NOTE

:
Align matching marks (A) on the thread edge of companion flange and drive pinion and install companion flange if drive pinion is reused.

8. Tap the companion flange (1) with a plastic hammer as far as


8. Tap the companion flange (1) with a plastic hammer as far as the lock nut can be tightened.

CAUTION:
Never damage drive pinion oil seal.

9. Apply anti-corrosive oil to the thread and seat of the lock nut, and temporarily tighten lock nut to the drive pinion.

CAUTION:
Never reuse lock nut.

10. Tighten lock nut within the specified torque range with a preload gauge (A) (SST: ST3127S000) so that the drive pinion bearing preload is within standard.

Drive pinion bearing preload : Refer to DLN-117, "Preload Torque".

CAUTION:
Start the tightening of lock nut from lower limit of the specified torque. Check the preload every 5 to 10 while tightening the lock nut.

Replace the collapsible spacer and tighten it again to adjust if preload exceeds the specified value. Never loosen lock nut to adjust preload.

After adjustment, rotate the drive pinion back and forth from 2 to 3 times to check for unusual noise, sticking, binding, and so on.

11. Install ring gear shaft assembly. Refer to DLN-97, "Assembly".

12. Install transfer cover. Refer to DLN-114, "Assembly".

13. Check backlash, tooth contact, total preload and companion flange runout. Refer to DLN-98, "Adjustment".

CAUTION:
Measure the total preload without the transfer case oil seal.

Adjustment

About adjusting of drive pinion, refer to DLN-98, "Adjustment".

Inspection

INSPECTION AFTER DISASSEMBLY

Check items below. If necessary, replace them with new ones.

Gear and Shaft Check gear face and shaft for wear, cracks, damage, and seizure.

CAUTION:
Replace ring gear and drive pinion as a set (hypoid gear set) if any malfunction is detected on the ring gear or drive pinion.

Bearing
Check for seizure, peeling, wear, corrosion, sticking, unusual noise, roughness in hand turning, and other damage.

CAUTION:
Always replace inner race and outer race as a pair when replacing the bearing.

Shim
Check for seizure, damage, and unusual wear.

Case
Check the bearing mounting surface for wear, cracks and damages.

CAUTION

:
Replace transfer case and transfer cover as a set if any malfunction is detected on transfer case or transfer cover.
