1. DIFFERENTIAL CASE ASSEMBLY 1. Install the washer and differential bevel gear into differential case (LH).
2. Install the differential bevel gear pinions into differential case (LH) and install the pinion shaft.
3. Install the straight pin.
4. Install the differential case (RH) to hypoid driven gear and secure with vise.
5. Install the washer and differential bevel gear to the differential case (RH).
6. Using the ST, install the hypoid driven gear by tightening the installation bolt.
Tightening torque: 20 N·m (2.0 kgf-m, 14.8 ft-lb)
7. While checking the tightening angle with the angle gauge, further tighten the hypoid driven gear mounting bolts. Tightening angle: 45°±2° 8. Measurement of backlash (selection of washer) (1) Install the SUBARU genuine axle shaft to differential case.
(2) Measure the gear backlash using ST1 and ST2, and then insert the ST2 through the window of differential case.
NOTE: • Measure the backlash by applying a differential bevel pinion tooth between two differential bevel gear teeth. • When measuring, fix the differential bevel pinion in place with a screwdriver covered with cloth, or a similar tool. Specification: 0.13 — 0.18 mm (0.0051 — 0.0071 in)
(3) If the backlash is not within specification, select a washer from the table below and replace.
9. Using the ST, install the left and right taper roller bearings.
2. SIDE RETAINER NOTE: After adjusting the backlash and tooth contact, replace the oil seal and O-ring of side retainer with new parts. 1. Press-fit the bearing outer race to side retainer. 2. Using the ST, install the oil seal. NOTE: • Use a new oil seal. • Apply differential oil to the oil seal lip. • Oil seal has an identification mark (R, L). When installing oil seals, do not confuse the left and right.
3. Install the O-rings. NOTE: • Use new O-rings. • Apply gear oil to O-ring.
