Differential: Service and Repair
NOTE: The bearings do not need to be removed unless you are replacing them.
DISASSEMBLY / ASSEMBLY
1. Before disassembly, inspect the backlash of the side gears and pinion gears, referring to the following procedure:
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 joint shaft on V-blocks.
c. Measure the backlash of both pinion gears.
d. If the backlash exceeds 0 - 0.1 mm (0 - 0.004 inch), adjust by selecting and installing thrust washers between the case and the side gears. Thrust washer available thicknesses are 2.0 mm (0.079 inch), 2.1 mm (0.083 inch), or 2.2 mm (0.087 inch).
CAUTION: Use thrust washers with the same thickness on each side.
2. Disassemble in the order shown in the illustration, referring to Disassembly Note.
3. Assemble in the reverse order of disassembly, referring to Assembly Note.
4. Measure the backlash after assembly, referring to previous procedure.
