      Reused 2.14 to 2.45 N*m (22 to 24 kgf*cm, 19 to 21 in.*lbf)

      If the preload is more than the specification, replace the bearing spacer.

      If the preload is less than the specification, tighten the nut with 13 N*m (130 kgf*cm, 9 ft.*lbf) of torque at a time until the specified preload is reached.

      Torque:
      451 N*m  { 4599 kgf*cm, 333 ft.*lbf, or less }

      If the maximum torque is exceeded while tightening the nut, replace the bearing spacer and repeat the preload procedure.

      Tech Tips

      Do not loosen the nut to reduce the preload.

  39. INSPECT TOTAL PRELOAD


    1. A01ESBN

      With the drive pinion contacting the tooth side of the ring gear, use a torque wrench to measure the total preload.

      Standard Total Preload (at starting)
      Bearing Specified Condition
      New 4.58 to 5.88 N*m (47 to 59 kgf*cm, 41 to 52 in.*lbf)
      Reused 3.47 to 4.58 N*m (36 to 46 kgf*cm, 31 to 40 in.*lbf)

  40. INSPECT BACKLASH BETWEEN DIFFERENTIAL RING GEAR AND DIFFERENTIAL DRIVE PINION


    1. A01EONWE02

      Using SST and a dial indicator, measure the ring gear backlash.

      SST
      09564-33010
      Standard backlash
      0.17 to 0.27 mm (0.00670 to 0.0106 in.)

  41. INSPECT RUNOUT OF FRONT DRIVE PINION COMPANION FLANGE SUB-ASSEMBLY


    1. A01ESMNE03
      Text in Illustration
      *a Vertical Runout
      *b Lateral Runout
      *c 55 mm (2.17 in.)

      Using a dial indicator, measure the runout of the companion flange vertically and laterally.

      Maximum Runout
      Runout Specified Condition
      Vertical runout 0.10 mm (0.00394 in.)
      Lateral runout 0.10 mm (0.00394 in.)

      If the runout is more than the maximum, replace the companion flange.

  42. STAKE FRONT DRIVE PINION COMPANION FLANGE FRONT NUT


    1. A01EN28

      Using a chisel and hammer, stake the nut.

  43. INSTALL DIFFERENTIAL SIDE GEAR SHAFT OIL SEAL


    1. A01EPW8E01

      Using SST and a plastic-faced hammer, tap in a new oil seal until its surface is flush with the differential carrier end.

      SST
      09608-32010

    2. Coat the lip of the oil seal with MP grease.

      Standard oil seal depth
      -0.45 to 0.45 mm (-0.0177 to 0.0177 in.)

  44. INSTALL DIFFERENTIAL EXTENSION FLANGE TUBE


    1. Remove any old FIPG material and be careful not to drop oil on the contact surfaces of the differential tube and bearing retainer.

    2. Wipe off any residual FIPG material on the contact surface using gasoline or alcohol.

    3. A01EQE3E02
      Text in Illustration
      *a Seal Packing

      Apply seal packing to the bearing retainer as shown in the illustration.

      Seal packing
      Toyota Genuine Seal Packing 1281, Three Bond 1281 or equivalent
      Standard Seal Diameter (A)
      2.0 to 3.0 mm (0.0788 to 0.118 in.)

      Tech Tips

      Install the differential tube within 10 minutes of applying seal packing.

    4. Install the differential tube onto the bearing retainer.

    5. A01EPKK

      Install 4 new bolts.

      Torque:
      65 N*m  { 663 kgf*cm, 48 ft.*lbf, or less }

      Note

      Do not add oil or drive the vehicle immediately after installing the cover, and leave it as is for at least an hour. Also, for 12 hours or less, avoid rapid acceleration/deceleration.
