      09229-55010
      Total Preload (at Starting)
      A Type
      Item Specified Condition
      New rear drive pinion tapered roller bearing 1.81 to 3.41 N*m (18.46 to 34.77 kgf*cm, 16.02 to 30.18 in.*lbf)

      B Type
      Item Specified Condition
      New rear drive pinion tapered roller bearing 2.00 to 3.77 N*m (20.39 to 38.44 kgf*cm, 17.70 to 33.37 in.*lbf)
      Used rear drive pinion tapered roller bearing 0.89 to 2.01 N*m (9.08 to 20.50 kgf*cm, 7.88 to 17.79 in.*lbf)

      Note


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

      • If the preload is greater than the specified value, replace the rear differential side gear shaft snap ring of the 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).

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

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

      Backlash
      0.08 to 0.13 mm (0.00315 to 0.00512 in.)

      Note


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

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

    4. Recheck the total preload.

  27. INSPECT TOOTH CONTACT BETWEEN RING GEAR AND DRIVE PINION


    1. A0162BM

      A015ZRUE03
    4. A01639BE01

      If the teeth are not contacting properly, use the following table to select a proper 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 drive pinion washer has been changed, adjust the backlash and measure the total preload.
