  1. Using a plastic hammer, remove the front differential ring gear from the front differential case.



3. INSPECT FRONT DIFFERENTIAL SIDE GEAR BACKLASH


Yaris. Ncp93, 131
  1. Fix 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 outside the specifications, replace the front No. 1 differential side gear thrust washers.


4. REMOVE FRONT DIFFERENTIAL PINION SHAFT STRAIGHT PIN


Yaris. Ncp93, 131
  1. Using a chisel and a hammer, loosen the staked part of the front differential case.

  1. Using a pin punch (φ3 mm) and a hammer, remove the front differential pinion shaft straight pin from the front differential case.



5. REMOVE FRONT NO. 1 DIFFERENTIAL PINION SHAFT


Yaris. Ncp93, 131
  1. Remove the front No. 1 differential pinion shaft from the front differential case.



6. REMOVE FRONT DIFFERENTIAL SIDE GEAR


Yaris. Ncp93, 131
  1. Remove the 2 front differential pinions, 2 front differential pinion thrust washers, 2 front No. 1 differential side gear thrust washers, and 2 front differential side gears from the front differential case.

    HINT:
    Revolving the front differential pinion, remove the 2 front differential pinions and 2 front differential side gears.
