Front Differential Assembly: Adjustment

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

Remove the oil pump cover.
Remove the liquid gasket from the mating surface completely.
Install the oil pump cover to converter case, and secure them with tightening four bolts evenly.
NOTE: Use an old gasket or aluminum washer to prevent damaging the mating surface of the housing.

Tightening torque:

41 N.m (4.2 kgf-m, 30.4 ft-lb)
Rotate the drive pinion ten times or more using ST1 and ST2.

Tighten the LH retainer by rotating the shaft until resistance is felt. Then loosen the retainer RH. Keep tightening the retainer LH, and loosening the retainer RH until the pinion shaft no longer be turned. This is the "zero" state.

Fig 3: Identifying Retainer
After the "zero" state is established, back off the retainer LH 3 notches and secure it with the lock plate. Then back off the retainer RH and retighten until it stops. Rotate the drive pinion 2 or 3 times. Tighten the retainer RH further 1-3/4 notches. This sets the preload. Finally, secure the retainer with its lock plate.

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

Fig 5: Turning Retainer
Turn the drive pinion several times using ST1, and check to see if the backlash is within the specification using ST2, ST3, ST4 and ST5.
