      Using a plastic hammer, lightly tap the differential ring gear tooth side of the rear differential carrier to stabilize the rear differential case bearing.

    6. B0073K7

      Using a dial indicator, measure the ring gear backlash of the differential ring gear at 3 positions. If even one ring gear backlash reading is smaller than the specified value, adjust the differential ring gear backlash by replacing the rear differential side gear shaft snap ring on the differential ring gear tooth side with a thicker one.

      Standard Backlash
      0.08 to 0.13 mm (0.00315 to 0.00511 in.)

      If the value is not within the specified range, replace the rear differential side gear shaft snap ring with one of a different thickness in the following procedure.

    7. B0076M4

      Remove the 2 bolts and SST.

  14. ADJUST TOTAL PRELOAD


    1. Turn the bearing clockwise and counterclockwise several times to stabilize it.

    2. B00730NN07

      Using SST and a torque wrench, measure the preload with the teeth of the differential drive pinion and differential ring gear in contact.

      SST
      09229-55010
      Standard Total preload (Starting Torque)
      Item Specified Condition
      New bearing 1.77 to 3.29 N*m (19 to 33 kgf*cm, 16 to 29 in.*lbf)
      Reused bearing 1.61 to 2.77 N*m (17 to 28 kgf*cm, 15 to 24 in.*lbf)

      Note


      • If the measured preload is less than the specified value, replace the rear differential side gear shaft snap ring of the differential ring gear tooth surface side with a thicker one.

      • If the measured preload is more than the specified value, replace the rear differential side gear shaft snap ring of the differential ring gear tooth surface side with a thinner one.

      Tech Tips

      When the rear differential side gear shaft snap ring thickness changes by 0.02 mm (0.000787 in.), the total preload will change by approximately 0.1 N*m (1 kgf*cm, 1 in.*lbf).

    3. B0073K7

      Set a dial indicator to the end of the differential ring gear face.

    4. While holding the rear drive pinion companion flange, rotate the differential ring gear and measure the ring gear backlash.

      Standard Backlash
      0.08 to 0.13 mm (0.00315 to 0.00511 in.)

      Tech Tips


      • If the measured value is out of the specified range, adjust it by increasing or decreasing the thickness of both the right and left rear differential side gear shaft snap rings equally.

      • When the rear differential side gear shaft snap ring thickness changes by 0.02 mm (0.000787 in.), the ring gear backlash also changes by 0.02 mm (0.000787 in.).

    5. Recheck the total preload.

      Note

      Check the tooth contact pattern at 4 or more positions around circumference of the differential ring gear.

    4. B0076WJC02
      *1 Rear Differential Drive Pinion Plate Washer

      If the teeth are not contacting properly, use the following table to select a proper rear differential drive pinion plate washer for correction.

      Tech Tips


      • If the contact pattern is face contact or flank contact, tooth contact may be adjustable while keeping the backlash within the specified range.

      • If the thickness of the rear differential drive pinion plate washer has been changed, adjust the ring gear backlash and measure the total preload.

        Torque
        490 N*m (4997 kgf*cm, 361 ft.*lbf) or less

      • If the preload is less than the specified minimum value even when the tightening torque of the rear drive pinion nut is more than the specified maximum value, remove the rear drive pinion nut and check that the threads of the rear drive pinion nut and differential drive pinion are not damaged.
