Front Differential: Adjustment

Using ST, screw in the retainer until light contact is felt.
NOTE: Screw in the RH side slightly deeper than the LH side.

Remove the oil pump housing.
Install the oil pump housing assembly to the torque converter clutch case, and secure evenly by tightening four bolts.
CAUTION:
- Thoroughly remove the liquid gasket from the case mating surface beforehand.
- Use an old gasket or an aluminum washer so as not to damage the mating surface of the housing.
Tightening torque:
1. 41 N.m (4.2 kgf-m, 30.4 ft-lb)

Fig 3: Rotating Drive Pinion
Tighten the LH retainer until contact is felt while rotating the shaft. Then loosen the RH retainer. Keep tightening the LH retainer and loosening the RH retainer until the pinion shaft can no longer be turned. This is the "zero" state.

Fig 4: Adjusting To "zero" State Position
After the "zero" state is established, back off the LH retainer 3 notches and secure it with the lock plate. Then back off the RH retainer and retighten until it stops. Repeat this procedure several times. Tighten the RH retainer 1-3/4 notches further. This sets the preload. Finally, secure the retainer with its lock plate.

NOTE: Turning the retainer by one tooth changes the backlash about 0.05 mm (0.0020 in).

Fig 6: Identifying Retainer Adjustment Relationship To Backlash Change
Turn the drive pinion several rotations with ST1 and check to see if the backlash is within the standard value with ST2, ST3, ST4 and ST5.
NOTE: After confirming that the backlash is correct, check the tooth contact.
