DIFFERENTIAL CASE INSPECTION

PROCEDURE

1. INSPECT FRONT DIFFERENTIAL CASE

   1. 

      Using SST, rotate the front differential side gear as shown in the illustration.

      09528-52010

      09528-05030

      Standard

      The front differential side gear does not lock when rotated in either direction.

      • If the front differential side gear locks, perform all inspections.

      • If the front differential side gear still locks even after replacing the malfunctioning parts, replace the front differential case.

2. INSPECT FRONT DIFFERENTIAL PINION BACKLASH

   1. Install SST as shown in the illustration and tighten it.

      Turn

      *b

      Hold

      09528-05010

      10 N*m

      102 kgf*cm

      7 ft.*lbf

   2. Secure the front differential case with front differential ring gear in a vise between aluminum plates

      Note:

      Do not overtighten the vise.

   3. 

      *1	Front No. 1 Differential Pinion Shaft

      Install the front No. 1 differential pinion shaft to the front differential pinion as shown in the illustration.

   4. Using a dial indicator, measure the front differential pinion backlash.

      Standard Backlash

      0.20 mm (0.00787 in.) or less

      If the backlash is not as specified, replace the 2 front No. 1 differential side gear thrust washers with washers of a different thickness. Use the table below to select a front No. 1 differential side gear thrust washer which will ensure that the backlash is within the specification.

      Table 1. Front No. 1 Differential Side Gear Thrust Washer Thickness:

      Part No.	Thickness (mm (in.))
      41361-73050	0.90 (0.0354)
      41361-73010	1.00 (0.0394)
      41361-73020	1.10 (0.0433)
      41361-73030	1.20 (0.0472)

      Tip:

      Select 2 front No. 1 differential side gear thrust washers of the same thickness for both the right and left side.

3. INSPECT FRONT DIFFERENTIAL PINION THRUST WASHER

   1. 

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

      Minimum Thickness

      0.90 mm (0.0954 in.)

      Tip:

      Measure the most worn portion of the front differential pinion thrust washer.

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

4. 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.
