3) Set the one way clutch inner race to low clutch
drum. Make sure that the forward clutch is free in
the clockwise direction and locked in the counter
clockwise direction, as viewed from the front of the
vehicle.

MANUAL TRANSMISSION AND DIFFERENTIAL
Front Differential Assembly
E: INSPECTION
Repair or replace the differential gear in the follow-
ing cases:
The hypoid drive gear and drive pinion shaft
tooth surface are damaged, excessively worn, or
seized.
The roller bearing on the drive pinion shaft has a
worn or damaged roller path.
There is damage, wear, or seizure of the differ-
ential bevel pinion, differential bevel gear, washer,
pinion shaft, and straight pin.
The differential case has worn or damaged slid-
ing surfaces.
1. DIFFERENTIAL BEVEL PINION GEAR
BACKLASH
Measure the backlash between differential bevel
gear and pinion. If it is not within specifications, in-
stall a suitable washer to adjust it.
NOTE:
Be sure the pinion gear tooth contacts adjacent
gear teeth during measurement.

ST2 498247100 DIAL GAUGE
Standard backlash:
0.13 — 0.18 mm (0.0051 — 0.0071 in)
2. HYPOID GEAR BACKLASH
1) Set the ST1, ST2 and ST3. Insert the needle
through transmission oil drain plug hole so that the
needle comes in contact with the tooth surface at a
right angle.

2) Install the axle shaft (SUBARU Genuine Parts)
to both sides, move it clockwise and counter clock-
wise to contact tooth, and then read the value of
dial gauge runout.
