Drive Pinion: Assembly
- Select drive pinion adjusting shim. Refer to "ADJUSTMENT ".
- Install selected drive pinion adjusting shim to drive pinion.
- Install inner race of drive pinion bearing (front side) to drive pinion with a drift (A) [SST: ST23860000 (-)].CAUTION:
- Never reuse drive pinion bearing (front side).
- Apply gear oil to the drive pinion bearing (front side).
- 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).
- Install drive pinion oil seal to transfer case with drifts so that it becomes flush with case end surface.

CAUTION:- Never reuse oil seal.
- Apply multi-purpose grease onto oil seal lips, and gear oil onto the circumference.
- Assemble a collapsible spacer onto the drive pinion.CAUTION: Never reuse the collapsible spacer.
- 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.
- Tap the companion flange with a plastic hammer as far as the lock nut can be tightened.CAUTION: Never damage drive pinion oil seal.
- 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.
- 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.
Standard
Drive pinion bearing preload: Refer to "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.
- Install ring gear shaft assembly. Refer to "ASSEMBLY ".
- Install adapter case. Refer to "ASSEMBLY ".
- Check backlash, tooth contact, total preload and companion flange runout. Refer to
"ADJUSTMENT ".CAUTION: Measure the total preload without the adapter case oil seal.
