Differential Gear
1. Remove the ball bearing (1) with a puller.
2. Remove the differential case cover mounting screws (13), then
take out the differential case cover (7), ball bearing (8) and spiral
bevel gear (9) as a unit.
3. Remove the external snap ring (10), then remove the ball bearing
(8) and spiral bevel gear (9).
4. Tap out the spring pin (11).
5. Pull out the differential pinion shaft (12), then take out the
differential pinions (6) and differential side gears (4).
NOTE
• Arrange the parts to know their original position.
(When reassembling)
• Apply molybdenum disulfide (Three Bond 1901 or equivalent) to
the inner circumferential surface of the differential side gears (4)
and differential pinions (6).
• Install the differential pinion shaft (12) so that the hole on it may
align with the hole on differential case (2), and install the spring
pin (11).
