Differential
Disassembly/Inspection/Assembly
1. Before disassembly, inspect backlash of side gears and pinion gears.
2. Disassemble in order shown in figure.
3. Inspect all parts and repair or replace as necessary.
4. Assemble in reverse order of disassembly.
5. Measure backlash after assembly.
Preinspection
Backlash of side gear and pinion gear
Measure backlash by following procedure:
1. Install left driveshaft and right joint shaft in differential assembly.
2. Support shafts on V-blocks as shown in figure.
3. Measure backlash of both pinion gears.
Backlash: 0.002 - 0.006 inch (0.05 - 0.15 mm)
4. If not as specified, replace worn and damaged parts.
Disassembly note
Bearing (ring gear opposite side)
Notice: Do not remove the bearing unless you are replacing it.
Remove bearing by using SST(OK130 171 013).
Side bearing inner race
Caution: Be careful not to drop differential case.
1. Using SST(OK670 990 AAO), remove side bearing inner race (opposite side of ring gear).
Bearing (ring gear side)
Remove bearing by using SST(OK670 99O AAO).
Inspection
1. Inspect all parts and repair or replace as necessary.
Ring gear and gear case assembly
1. Inspect ring gear for wear and cracks. If gear case is replaced, adjust bearing preload.
Bearing
1. Inspect for wear and rough rotation. If bearing is removed, then replace it and bearing race together, and adjust bearing preload.
Assembly note
Bearing (ring gear side)
1. Install new bearing by using SST(OK011 270 A02/K94U-0001 -Q).
Bearing (ring gear opposite side)
1. Install speedometer drive gear.
2. Install new bearing by using SST(OK011 270 A02/K94U-0001 -Q).
Roll pin
1. Install new roll pin as shown in figure to hold pinion shaft.
Backlash of side gear and pinion gear
Measure backlash by following procedure:
1. Install left driveshaft and right joint shaft in differential assembly.
2. Support shafts on V-blocks as shown in figure.
3. Measure backlash of both pinion gears.
Backlash: 0.002 - 0.006 inch (0.05 - 0.15 mm)
4. If not as specified, replace worn and damaged parts.
