Differential Gear
1. Remove the differential case cover mounting screws (9) and
then take out the differential case cover (5), ball bearing (6) and
spiral bevel gear (7) as a unit.
2. Remove the external snap ring (8), and then remove the ball
bearing (6) and spiral bevel gear (7) as unit with a puller.
3. Remove the straight pin (13).
4. Pull out the pinion shaft (10) and take out the differential pinions
(4) and differential side gears (12).
(When reassembling)
• Apply molybdenum disulfide (Three Bond 1901 or equivalent) to
the inner circumferential surface of the differential side fears
(12) and differential pinions (4).

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