Tool number: ST33230000 (J25805-01)
CAUTION:
- When checking the Total preload torque, measure it without the oil seal, then install the oil seal.
- Discard old oil seals, replace with new ones.
- Apply multi-purpose grease onto oil seal lips, and gear oil onto the circumference of the oil seal.
- The oil seal back position after the installation shall be 56.5 mm (2.22 in) from the gear ring end.
Apply a thread locking adhesive into the thread hole for the drive gear.

1. Completely clean and de grease the drive gear back face, thread holes, and drive gear mounting bolts. (Use a gasket remover to remove the thread locking adhesive.)
2. Apply a thread locking adhesive onto the first and second threads under the thread hole chamfering of the drive gear on 3 or more different points.
Install the drive gear to gear ring, and apply anti-corrosive oil onto threads and seats on the mounting bolts, and then tighten to the specified torque.
Tightening torque

First (temporary tightening): 25 - 29 N.m (2.5 - 3.0 kg-m, 18 - 21 ft-lb)

Second (final tightening): 82 - 115 N.m (8.3 - 11.7 kg-m, 60 - 84 ft-lb)
CAUTION:
- Temporary installation before tightening the bolts through to the completion of the tightening should be within 90 seconds.
- If the thread locking adhesive is applied aside, quickly wipe it off.
Apply gear oil to gear ring bearing inner race on the transfer case. Using a drift, install gear ring bearing inner race.
