Differential Case -- Disassembly |
1. REMOVE SPEEDOMETER DRIVE GEAR |
Remove the speedometer drive gear from the front differential case assembly.
2. INSPECT FRONT DIFFERENTIAL SIDE GEAR BACKLASH |
Hold the front differential pinion to the front differential case side. Using a dial indicator, measure the front differential side gear backlash.
- Standard backlash:
- 0.05 to 0.20 mm (0.00197 to 0.00787 in.)
If the backlash is out of specification, adjust it using new side gear thrust washers (COROLLA_ZRE142 RM000000Z25018X_01_0002.html).
3. REMOVE FRONT DIFFERENTIAL RING GEAR |
Put matchmarks on the front differential ring gear and the front differential case.
Remove the 16 bolts.
Using a plastic hammer, remove the front differential case.
4. REMOVE FRONT DIFFERENTIAL PINION SHAFT STRAIGHT PIN |
Using SST and a hammer, unstake the staked part of the front differential case.
- SST
- 09930-00010
Using a pin punch and a hammer, remove the front differential pinion shaft straight pin from the front differential case.
5. REMOVE FRONT NO. 1 DIFFERENTIAL PINION SHAFT |
Remove the front No. 1 differential pinion shaft from the front differential case.
6. REMOVE FRONT DIFFERENTIAL SIDE GEAR |
Remove the 2 front differential pinions, 2 front differential pinion thrust washers, 2 front differential side gears, and 2 front differential side gear thrust washers from the front differential case.
- HINT:
- Remove the 2 pinion thrust washers and side gear thrust washers while turning the front differential pinion.
