Differential: Service and Repair

NOTE: The bearings do not need to be removed unless you are replacing them.





DISASSEMBLY
1. Before disassembly, inspect the backlash of the side gears and pinion gears, referring to Preinspection. Testing and Inspection
2. Disassemble in the order shown in the illustration, referring to the following notes:





Bearing (side opposite ring gear)
While supporting the gear case, remove the bearing (side opposite ring gear) by using the Special Service Tool (SST).





Bearing (ring gear side)
Remove the bearing (ring gear side) by using the SST.

INSPECTION





Inspect Ring Gear And Gear Case Assembly
Inspect the ring gear for wear and cracks. Refer to bearing preload adjustment if the ring gear and gear case assembly is being replaced. Adjustments





Inspect Bearing
Inspect for wear and rough rotation. If replacing the bearing, replace the bearing and race as an assembly.

ASSEMBLY

Assemble in the reverse order of disassembly, referring to the following notes:





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

Bearing (side opposite ring gear)
1. Install the speedometer drive gear.





2. Install the new bearing (side opposite ring gear) by using the SST.





Roll pin
Install the new roll pin with the split facing as shown.





Backlash of side gear and pinion gear
Measure the backlash after assembly, referring to the following. Measure the backlash by the following procedure:
a. Install the left drive shaft and the joint shaft in the differential assembly.
b. Support the drive shaft and the joint shaft on V-blocks.
c. Measure the backlash of both pinion gears.
d. If not within 0.050 - 0.150 mm (0.0020 - 0.059 inch), replace parts as necessary.
