DIFFERENTIAL CASE INSPECTION

PROCEDURE


  1. INSPECT DIFFERENTIAL CASE


    1. A004R1GE02

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

      SST
      09528-52010   ( 09528-05030 )
      Standard
      The front differential side gear does not lock when rotated in either direction.

      • If the differential side gear locks, perform all remaining inspection procedures.

      • Replace any parts that do not meet the specifications.

      • If the differential side gear locks after performing the inspection procedures, replace the differential case.

  2. INSPECT DIFFERENTIAL SIDE GEAR THRUST AMOUNT

      *a Thrust Amount

      Using SST and a dial indicator, measure the thrust amount of the differential side gear.

      SST
      09528-52010   ( 09528-05030 )
      Standard Thrust Amount
      0.08 mm (0.00314 in.) or less

      Tech Tips


      • Measure the differential side gear thrust amount while slowly rotating the differential side gear.

      • Make sure to measure the differential side gear thrust amount for both of the differential side gears.

      If the result is not as specified, replace the 2 conical spring washers, 2 differential side gears and 2 front differential pinions.

  3. INSPECT DIFFERENTIAL SIDE GEAR BACKLASH


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

      SST
      09528-52010   ( 09528-05010, 09953-05010 )
      Torque:
      10 N*m  { 102 kgf*cm, 7 ft.*lbf }

    2. Hold the differential case in a vise between aluminum plates.

      Note

      Do not overtighten the vise.

      *1 No. 1 Front Differential Pinion Shaft

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

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

      SST
      09528-52010   ( 09528-05010, 09953-05010 )
      Standard Backlash
      0.05 to 0.15 mm (0.00197 to 0.00590 in.)

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

      No. 1 Front Differential Side Gear Thrust Washer Thickness
      Thickness Thickness
      1.50 mm (0.0591 in.) 1.75 mm (0.0689 in.)
      1.55 mm (0.0610 in.) 1.80 mm (0.0709 in.)
      1.60 mm (0.0630 in.) 1.85 mm (0.0728 in.)
      1.65 mm (0.0650 in.) 1.90 mm (0.0748 in.)
      1.70 mm (0.0669 in.) -

      Tech Tips

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