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



3. INSPECT FRONT DIFFERENTIAL SIDE GEAR BACKLASH


    Corolla. Zre142 Aze141
  1. Secure 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 RM000001A0Z042X_01_0001.html).


4. REMOVE FRONT DIFFERENTIAL PINION SHAFT STRAIGHT PIN


    Corolla. Zre142 Aze141
  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


    Corolla. Zre142 Aze141
  1. Remove the front No. 1 differential pinion shaft from the front differential case.



6. REMOVE FRONT DIFFERENTIAL SIDE GEAR


    Corolla. Zre142 Aze141
  1. Remove the 2 front differential pinions, 2 front differential pinion thrust washers, 2 No. 1 front differential side gear thrust washers, and 2 front differential side gears from the front differential case.
