AA" INSPECTION BEFORE DISASSEMBLY
1. Remove the cover.
2. Hold the special tool in a vise, and install the differential
carrier assembly to the special tool.
DRIVE GEAR BACKLASH
1. With the drive pinion locked in place, use a dial gauge
to measure the drive gear backlash in four or more places
on the drive gear.
Standard value: 0.11 - 0.16 mm
2. If the backlash is not within the standard value, adjust
the final drive gear backlash. (Refer to P.27B-49.)
3. After the adjustment, inspect the drive gear tooth contact.
DRIVE GEAR RUNOUT
1. Measure the drive gear runout at the shoulder on the
reverse side of the drive gear.
Limit: 0.05 mm
2. When runout exceeds the limit value, check for foreign
object between drive gear rear side and differential case,
or for loose drive gear installation bolts.
3. When check (2) gives normal results, reposition drive
gear and differential case and remeasure.
4. If adjustment is impossible, replace differential case, or
replace drive gear and pinion as a set.
