Differential

CAUTION:
- Do not remove the bearings if not necessary. Replace them if removed.
- Replace the bearing race if a side bearing is replaced.




1. Before disassembly, inspect the backlash of the side gears and pinion gears, referring to Preinspection.
2. Disassemble in the order shown in the image, referring to Disassembly Note.
3. Inspect all parts and repair or replace as necessary.
4. Assemble in the reverse order of disassembly, referring to Assembly Note
5. Measure the backlash after assembly, referring to Backlash of Side Gear and Pinion Gear.




Preinspection
Backlash of side gear and pinion gear
Measure the backlash by the following procedure.
1. Install the left and right drive shafts in the differential assembly.
2. Support the drive shafts on V-blocks as shown in the image.
3. Measure the backlash of both pinion gears.

Backlash: 0-0.1mm (0-0.004 in)

4. If the backlash exceeds specification, adjust by selecting and installing thrust washers between the case and the side gears.

CAUTION: Use thrust washers with the same thickness on each side.

Thrust Washer Thickness:

Thrust Washer thickness




Disassembly Note
Bearing (side opposite ring gear)

CAUTION: Hold the gear case with one hand so that it does not fall.

Remove the bearing by using the SSTs.




Bearing (ring gear side)

NOTE: Use pads in the vise to prevent damaging the differential assembly.

Remove the bearing by using the SST.




Inspection
Inspect all parts and repair or replace as necessary.

Ring gear and gear case assembly

NOTE: If the gear case is replaced, adjust the bearing preload.

Inspect the ring gear for wear and cracks.




Bearing

NOTE: When replacing the bearing, replace it and the bearing race as a set.

Inspect for wear and rough rotation.




Assembly Note
Bearing (ring gear side)
Install the bearing by using the SST.




Bearing (side opposite ring gear)
1. Install the speedometer drive gear.
2. Install the new bearing by using the SST.




Roll pin
Install the new roll pin as shown in the image to hold the pinion shaft.




Backlash of Side Gear and Pinion Gear
Measure the backlash by the following procedure.
1. Install the drive shafts in the differential assembly.
2. Support the drive shafts on V-blocks as shown in the image.
3. Measure the backlash of both pinion gears.

Backlash: 0-0.1mm (0-0.004 in)

4. If not as specified, select the proper thrust washers.
