DRIVE GEAR RUNOUT
1. Measure the drive gear runout at the shoulder on the reverse side of the drive gear.
Limit: 0.05 mm (0.002 inch)
2. When runout exceeds the limit value, check for foreign material between drive gear rear side and differential case, or for loose drive gear
installation bolts.
3. When step (2) gives normal results, reposition the drive gear and differential case and remeasure.
4. If adjustment is impossible, replace the differential case, or replace the drive gear and pinion as a set.
DIFFERENTIAL GEAR BACKLASH
1. While locking the side gear with the wedge, measure the differential gear backlash with a dial indicator on the pinion gear.
Standard value: 0 - 0.076 mm (0 - 0.0030 inch)
Limit: 0.2 mm (0.007 inch)
Use the measurement procedure for both pinion gears.
2. If the backlash exceeds the limit, adjust by using the side gear thrust spacers.
3. If adjustment is impossible, replace the side gear and pinion gear as a set.
