  3. Select the drive pinion shim.
    1. Using the ST and a micrometer, measure the dimension "A" from the ST end face to the drive pinion (gear portion) end face.

      Preparation tool: 

      ST: GAUGE (499575600)

    2. Using the ST and a press, press-fit a new taper roller bearing inner race (front side).

      Preparation tool: 

      ST: INSTALLER (499277200)

    3. Using a press, press-fit a new taper roller bearing outer race (A) and a new taper roller bearing (rear side) (B).
      NOTE: Press in to a position where the taper roller bearing rotates smoothly without play.

    5. Tighten the lock nuts using ST1 and ST2.
      CAUTION: Be sure to use a new lock nut.
      NOTE: Tighten the lock nut with ST1 and torque wrench aligned straight.

      Preparation tool: 

      ST1: WRENCH (499787700)

      ST2: HOLDER (18667AA010)

      Tightening torque: 

      Calculation formula
      T = 116 N.m (11.8 kgf-m, 85.6 ft-lb) x L/(100 mm (3.94 in) + L)
      T: Tightening torque
      L: Effective length of torque wrench
      NOTE: If the effective length of the torque wrench used is unknown, consult the manufacturer of the torque wrench.

    6. Measure the initial load of the taper roller bearing using the ST and a spring scale.
      CAUTION: Before checking the initial load, apply differential gear oil to the roller part of taper roller bearing, and rotate it several times to measure the value.
      NOTE: If it exceeds the standard value, replace the taper roller bearing.

      Initial load: 

      1.5 - 4.7 kgf (14.33 - 46.37 N, 3.22 - 10.42 lbf)

      Preparation tool: 

      ST: HOLDER (18667AA010)

    7. Crimp the lock nut in 2 locations.
    8. Using the ST and a micrometer, measure the dimension "B" from the ST end face to the taper roller bearing outer race end face.

      Preparation tool: 

      ST: GAUGE (499575600)

    9. Using the following calculation, calculate an appropriate thickness "T" of the drive pinion shim.
    NOTE: Adjust using 1 - 3 pieces.

    T = (H2 - H1) - 6.55 mm (0.258 in)

    T Drive pinion shim thickness (mm (in))
    A Measured value (mm (in)) of step (1)
    B Measured value (mm (in)) of step (8)
    6.55 mm (0.258 in) Constant
  4. Install the drive pinion shim and drive pinion.
    CAUTION: Be careful not to bend the drive pinion shim.
    NOTE: Apply differential gear oil to the oil seal lip.

    Tightening torque: 

    70 N.m (7.1 kgf-m, 51.6 ft-lb)
