NOTE:

- If the transmission housing, torque converter housing, differential carrier, carrier bearing and outer race, or thrust shim were replaced, the bearing preload must be adjusted.
- Coat all parts with ATF during installation.
- Do not use the thrust shim in the torque converter housing.

1. Remove the bearing outer race (A), 76.2 mm thrust washer (B), and 76 mm thrust shim (C) from the transmission housing (D) by heating the housing to about 100 °C (212 °F) with a heat gun (E). Do not heat the housing more than 100 °C (212 °F).
   NOTE: Let the transmission housing cool to room temperature before adjusting the bearing preload.

1. Install the 76 mm thrust shim (A) in the transmission housing (B). If you replace the 76 mm thrust shim with a new one, use the same thickness shim as the old one.

1. Install the 76.2 mm thrust washer (C) and the bearing outer race (D) in the transmission housing.
   NOTE: Install the 76.2 mm thrust washer with the ‘‘41382RKY'' mark facing downward.

1. Install the bearing outer race securely so there is no clearance between the outer race, thrust washer, thrust shim and the transmission housing with the handle driver and 72 x 75 mm driver attachment.

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

1. Install the transmission housing (E) and the transmission hanger (F), then tighten the bolts.

1. Rotate the differential assembly in both directions to seat the bearings.

1. Measure the starting torque of the differential assembly in both directions with the preload inspection tool, a torque wrench (A) and socket (B) at normal room temperature.

   Standard
   New Bearing:
   2.7−3.9 N·m (28−40 kgf·cm, 24−35 lbf·in.)
   Reused Bearing:
   2.5−3.6 N·m (25−37 kgf·cm, 22−32 lbf·in.)

1. If the measurement is out of standard, remove the thrust shim and select the thrust shim from the following table. Install the new thrust shim and recheck. To increase the starting torque, increase the thickness of the thrust shim. To decrease the starting torque, decrease the thickness of the shim. Changing the shim to the next size will increase or decrease starting torque about 0.3−0.4 N·m (3−4 kgf·cm, 2−3 lbf·in).
