DIFFERENTIAL CASE INSPECTION

PROCEDURE

1. INSPECT DIFFERENTIAL SIDE GEAR BACKLASH

   1. 

      Hold the differential case in a vise between aluminum plates.

      Note:

      Do not overtighten the vise.

   2. Place a dial indicator on the tip of the side gear tooth at a right angle.

   3. Hold the pinion gear in the differential case and measure the backlash of the side gear.

      Standard backlash

      0.05 to 0.20 mm (0.00197 to 0.00787 in.)

      Table 1. Thrust Washer Thickness

      Thickness
      1.00 mm (0.0394 in.)
      1.10 mm (0.0433 in.)
      1.20 mm (0.0472 in.)
      1.30 mm (0.0512 in.)

      If the backlash is more than the standard range, select another front No. 1 differential side gear thrust washer.

2. INSPECT FRONT DIFFERENTIAL PINION THRUST WASHER

   1. 

      Using a micrometer, measure the thickness of thefront differential pinion thrust washer.

      Minimum Thickness

      0.90 mm (0.0354 in.)

      Tip:

      Measure the most worn portion of the frontdifferential pinion thrust washer.

      If the thickness is less than the minimum, replacethe front differential pinion thrust washer.

3. INSPECT FRONT NO. 1 DIFFERENTIAL PINION SHAFT

   1. 

      Using a micrometer, measure the outer diameter of the front No. 1 differential pinion shaft.

      Minimum Outer Diameter

      17.975 mm (0.708 in.)

      Tip:

      Measure the most worn portion of the front No. 1 differential pinion shaft.

      If the outer diameter is less than the minimum,replace the front No. 1 differential pinion shaft.
