b. Install a dial indicator to the rear differential carrier assy.
c. Tighten the SST bolt and alter the differential carrier's shape to create a 0.1 mm (0.004 in.)
clearance between the side bearing (outer race) and side gear shaft snap ring.
HINT:
Set the dial indicator to the rearmost position (upper side in the illustration) of the area
around where the side gear shaft oil seal is 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.
