      SST
      09330-00021
      Torque:
      337 N*m  { 3444 kgf*cm, 249 ft.*lbf, or less }

      Note


      • Tighten the rear drive pinion nut to approximately 100 N*m (1020 kgf*cm, 74 ft.*lbf), and then tighten it further while checking the differential drive pinion preload.

      • Apply hypoid gear oil LSD to the rear drive pinion nut and the threads of the differential drive pinion.

  17. ADJUST DIFFERENTIAL DRIVE PINION PRELOAD


    1. A01FIYR

      Using a torque wrench, measure the starting torque of the differential drive pinion.

      Tech Tips


      • The backlash between the differential drive pinion and differential ring gear should allow enough movement of the differential drive pinion to allow this measurement to be performed.

      • Make sure not to include the preload of the differential ring gear (rear differential case sub-assembly) in the measurement of the differential drive pinion preload.

      Differential Drive Pinion Preload (at Starting)
      Item Specified Condition
      New rear drive pinion tapered roller bearing 1.87 to 2.24 N*m (19.07 to 22.84 kgf*cm, 16.55 to 19.83 in.*lbf)
      Reused rear drive pinion tapered roller bearing 1.87 to 2.17 N*m (19.07 to 22.13 kgf*cm, 16.55 to 19.21 in.*lbf)

      • If the preload is less than the specified minimum value, check the preload while retightening the rear drive pinion nut by 5 to 10° to adjust it so that it is within the specified range.

        Torque
        337 N*m (3444 kgf*cm, 249 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, loosen the rear drive pinion nut and check that the threads of the rear drive pinion nut and differential drive pinion are not stripped.

      • If the threads are not stripped, replace the rear differential drive pinion bearing spacer. Apply hypoid gear oil LSD to the threads of the differential drive pinion and repeat the procedure.

  18. INSPECT TOTAL PRELOAD


    1. A01FIYR

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

      Total Preload (at Starting)
      Specification New Rear Drive Pinion Tapered Roller Bearing Reused Rear Drive Pinion Tapered Roller Bearing
      New differential case bearing 2.26 to 2.91 N*m (23.05 to 29.67 kgf*cm, 20.00 to 25.76 in.*lbf) 2.26 to 2.84 N*m (23.05 to 28.96 kgf*cm, 20.00 to 25.14 in.*lbf)
      Reused differential case bearing 2.17 to 2.80 N*m (22.13 to 28.55 kgf*cm, 19.21 to 24.78 in.*lbf) 2.17 to 2.73 N*m (22.13 to 27.84 kgf*cm, 19.21 to 24.16 in.*lbf)

      If the total preload is not within the specified range, adjust the total preload or perform repairs as necessary.

      Seal packing
      Toyota Genuine Seal Packing 1281, Three bond 1281 or equivalent

      Note


      • Apply the seal packing in a continuous line, approximately 2 to 3 mm (0.0787 to 0.118 in.) in diameter.

      • Overlap the seal packing at least 10 mm (0.394 in.) at the beginning and end of application.

      • Install the rear differential carrier cover within 3 minutes of application.

    2. A01FISF

      Install the rear differential carrier cover with the 8 bolts and 2 rear differential carrier straight pins.

      Torque:
      47 N*m  { 479 kgf*cm, 35 ft.*lbf }

      Note

      Do not fill the differential with oil or drive the vehicle immediately after installing the differential carrier cover. Leave the vehicle for at least 1 hour. Also, avoid sudden acceleration and deceleration for at least 12 hours after application.
