Differential Gear
1. Remove the spiral bevel gear (6) with bearing (5) and bearing
(1) with the puller.
2. Tap out the spring pin (2) and pull out the differential pinion
shaft (3).
3. Remove the differential pinion (7) and differential side gear (9).
A Arrange the parts to know their original position.
(When reassembling)
A Apply molybdenum disulfide (Three Bond 1901 or equivalent)
to the inner circumferential surface of the differential side
gears (9) and differential pinions (7).
A When inserting the spring pin (2), face its split in the direction
right-angled to the differential pinion shaft (3).

Clearance between Differential Case and Differential Side Gear
1. Measure the differential side gear boss O.D..
2. Measure the differential case bore I.D. and calculate the
clearance.
3. If the clearance exceeds the allowable limit, replace faulty
parts.
