[C] Differential Gear Assembly
Bearing and Differential Lock Shifter
1. Secure the differential gear in a vise.
2. Remove the ball bearing with a puller.
3. Remove the differential lock shifter.

Spiral Bevel Gear
1. Remove the spiral bevel gear.
(When reassembling)
• Check the spiral bevel gear for wear or damage. If it is no longer
serviceable, replace it. Then, also replace the spiral bevel
pinion.
• Apply liquid lock (Three Bond 1324 or equivalent) to the spiral
bevel gear UBS screws.

Differential Pinion and Differential Side Gear
1. Draw out the differential pinion shaft (2).
2. Remove the differential pinions (1), differential pinion washers
(7) and the differential side gears (6), differential side gear
washers (8).
• Arrange the parts to know their original position.
(When reassembling)
• Check the thrust and bearing surface of both differential side
gears (6). If they are worn or damaged, bores in the differential
case may also be damaged.
• Check the differential pinions (1) and pinion shaft (2) for
excessive wear. If these parts are damaged or excessively
worn, also replace parts they are in mesh with, or they are
sliding on.
• Apply molybdenum disulfide (Three Bond 1901 or equivalent) to
the inner circumferential surface of the differential pinions.
• Install the parts to their original position.
