k. Using a plastic hammer, lightly tap the drive pinion side of the differential carrier.
l. Check the backlash around the ring gear. If even one backlash is smaller than the
specified value, adjust the differential ring gear backlash by replacing the side gear
shaft snap ring on the drive pinion side with a thicker one.
Backlash: 0.08 to 0.13 mm (0.0031 to 0.0051 in.)
HINT:
If a value is not within the specified range, replace it with one of a different thickness
in the same procedure.

HINT:
Set the dial indicator to the rearmost position (upper side in the illustration) of the area
around where the side oil seal tapped in.
Approximately 0.1 mm (0.004 in.) clearance between the side bearing (outer race) and
the side gear shaft snap ring is sufficient enough for the washer to move slightly.

Using snap ring pliers, remove the side gear shaft snap ring on the drive pinion side.
HINT:
For reassembly purposes, measure the thickness of the side gear shaft snap ring. Write down
the result.
Remove the dial indicator and loosen the SST bolt.

f.REMOVE REAR DIFFERENTIAL CASE BEARING
a. Raise the ring gear side of the differential case slightly to remove the drive pinion side outer
race.
HINT:
For reassembly, check the installation position of the outer race and of the side gear shaft snap ring
before removing the outer race. Write down the result.
