Carrier Bearing Preload Inspection

Special Tools Required 

NOTE: If the transmission housing, the torque converter housing, the differential carrier, the tapered roller bearing, the bearing outer race, or the thrust shim were replaced, the bearing preload must be adjusted.
  1. Remove the bearing outer race (A), the spacer (B), and the 85 mm thrust shim (C) from the transmission housing (D) by heating the transmission housing to about 212°F (100°C) with a heat gun (E). Do not heat the transmission housing more than 212°F (100°C).
    NOTE: Let the transmission housing cool to room temperature before adjusting the bearing preload.

  2. Replace the tapered roller bearing when the bearing outer race is to be replaced.
  3. Do not use a shim on the torque converter housing side.
  4. Install the 85 mm thrust shim (A) in the transmission housing (B). If you replace the 85 mm thrust shim with a new one, use the same thickness shim as the old one.

  5. Install the spacer (C), and the bearing outer race (D) in the transmission housing.
  6. Drive the outer race securely in the transmission housing with the driver handle (15 x 135L) and the attachment (83 mm) so there is no clearance between the bearing outer race, the spacer, the shim, and the transmission housing.

  7. Install the differential assembly (A) in the torque converter housing (B), and install the gasket (C) and the two dowel pins (D) on the torque converter housing.

  8. Install the transmission housing (E), and install the mounting bolts (24 bolts) with the transmission hanger (F) and the ground terminal bracket (G), then tighten the bolts to the specified torque.
  9. Rotate the differential assembly in both directions to seat the bearings.
  10. Measure the starting torque of the differential assembly using the preload inspection tool, a torque wrench (A), and a socket (B). Measure the starting torque at normal room temperature in both directions.

    Standard 

    New bearings: 

    3.9-5.1 N.m (40-52 kgf.cm, 35-45 lbf.in) 

    Reused bearings: 

    3.6-4.8 N.m (37-49 kgf.cm, 32-43 lbf.in)

  11. If the measurement is out of standard, remove the 85 mm thrust shim and measure its thickness.
  12. Select a new 85 mm thrust shim. To increase the starting torque, increase thickness of the 85 mm thrust shim. To decrease the starting torque, decrease the thickness of the 85 mm thrust shim.

    Changing the 85 mm thrust shim to the next size will increase or decrease the starting torque about 0.5-0.6 N.m (5-6 kgf-cm, 5-5 lbf.in).
