ADJUSTMENT
1. Using the ST, screw-in the retainer until resistance is felt.
NOTE:
RH side should be screwed-in more than LH side.

2. Remove the remaining liquid gasket from the mating surface completely.
3. Using the ST, install the drive pinion assembly to converter case.

NOTE:
Do not confuse the three different-length bolts when installing.
Tightening torque:
43 N·m (4.4 kgf-m, 31.7 ft-lb)

4. Rotate the drive pinion shaft ten times or more using ST1 and ST2.

| ST2 499787700 | WRENCH |

5. While rotating the pinion shaft, tighten the retainer LH and loosen the retainer RH until the shaft can't be turned anymore. The backlash is “zero” when the pinion shaft comes to the point where it doesn't rotate.
6. After the “zero” state is established, loosen the retainer LH by 3 notches and secure it with the lock plate. Retighten the retainer RH 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 every one tooth changes the backlash approx. 0.05 mm (0.0020 in).

7. Insert the two SUBARU genuine axle shafts into differential case.

8. Install the ST to the drive pinion retainer, and wrap the drive pinion shaft with cloth and pinch with vise pliers. Using a tie-wrap or a wire, fix the vise pliers to the ST.
Make sure the drive pinion shaft does not move.
