DIFFERENTIALS
1. SIDE GEAR BACKLASH
Using a dial gauge, check the backlash of the side
gear.
Side gear backlash:
0.1 — 0.2 mm (0.004 — 0.008 in)
If the side gear backlash is not within the specifica-
tion, adjust clearance as specified by selecting the
side gear thrust washer.
2. CROWN GEAR BACKLASH
Using a dial gauge, check the backlash of the
crown gear.
Crown gear backlash:
0.1 — 0.2 mm (0.004 — 0.008 in)
If the crown gear backlash is not within the specifi-
cation, adjust the side bearing preload or repair if
necessary.
REAR DIFFERENTIAL
3. CROWN GEAR RUNOUT
Using a dial gauge, check the crown gear runout.
Crown gear runout:
Less than 0.05 mm (0.0020 in)
If the crown gear runout exceeds 0.05 mm (0.0020
in), replace the crown gear.
4. TOOTH CONTACT BETWEEN CROWN
DI-00315
GEAR AND DRIVE PINION
Inspect the tooth contact between crown gear and
driven pinion. <Ref. to DI-30, ASSEMBLY, Rear
Differential.>
5. TOTAL PRELOAD
Using a gauge, check the turning resistance in-
crease.
Total preload:
Except for STi model:
20.7 — 54.4 N (2.1 — 5.5 kgf, 4.7 — 12.2 lb)
STi model:
26.95 — 53.90 N (2.75 — 5.50 kgf, 6.1 — 12.1
lb)
If the total preload is not within the specification,
adjust the side bearing retainer shims.
