INSPECTION
Repair or replace the differential gear in the following cases:
• When the hypoid driven gear and drive pinion shaft tooth surfaces are damaged, excessively worn, or seized.
• When the roller bearing on the drive pinion shaft has a worn or damaged roller path.
• When there is damage, wear or seizure of the differential bevel pinion, differential bevel gear, adjusting washer, pinion shaft or straight pin.
• When the differential case sliding surfaces are worn or damaged.

1. DIFFERENTIAL BEVEL PINION GEAR BACKLASH
Measure the backlash between the differential bevel gear and differential bevel pinion. Adjust the backlash if not within specified limit. Front Differential Assembly > ADJUSTMENT">
NOTE:
Be sure the bevel pinion gear teeth contact adjacent gear teeth during measurement.
Standard backlash
0.13 — 0.18 mm (0.0051 — 0.0071 in)

2. HYPOID DRIVEN GEAR BACKLASH
1. Set the ST1, ST2 and ST3. Insert the needle through drain plug hole so that the needle comes in contact with the tooth surface on the right corner, and check the backlash.

2. Install SUBARU genuine axle shafts to both sides, rotate in the inversion direction so that the gauge contacts the tooth surface, and read the dial gauge.
NOTE:
If the backlash is outside the specified range, adjust it by turning the differential side retainer in the right side case.

3. TOOTH CONTACT OF HYPOID DRIVEN GEAR
Check tooth contact of hypoid driven gear as follows: Apply a thin uniform coat of red lead on both teeth surfaces of three to four teeth of the driven gear. Move the driven gear back and forth by turning the main shaft until a definite contact pattern is developed on the driven gear, and judge whether face contact is correct. When the contact pattern is not correct, adjust. Front Differential Assembly > ADJUSTMENT">
• Tooth contact is correct.
