Differential Case -- Disassembly



1. REMOVE SPEEDOMETER DRIVE GEAR


    Corolla. Zre142 Aze141
  1. Remove the speedometer drive gear from the front differential case assembly.



2. INSPECT FRONT DIFFERENTIAL SIDE GEAR BACKLASH


    Corolla. Zre142 Aze141
  1. 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
