NOTE:
If the transmission housing, the torque converter housing, the final drive shaft, the tapered roller bearing/bearing outer race, or the thrust shim is replaced, the bearing preload must be adjusted.
Apply a light coat of clean transmission fluid on all parts before installation.

2. Final Drive Shaft Tapered Roller Bearing Preload - Inspect
1.
Remove the bearing outer race (A) and the 51 mm thrust shim (B) by heating the torque converter housing to about 212 °F (100 °C) using a heat gun (C).
NOTE:
Do not heat the torque converter housing more than 212 °F (100 °C).
Let the torque converter housing cool to room temperature before adjusting the bearing preload.
2.
Install the bearing outer race (A) and the 51 mm thrust shim (B).
3.
Drive the bearing outer race (A) until it bottoms using the 40 mm I.D. driver handle.
5.
Install the final drive shaft assembly (A) and the differential assembly (B).
6.
Install the torque converter housing (A) with the dowel pins (B), and tighten the bolts in a crisscross pattern in at least two steps.
7.
Install the preload inspection tool.
8.
Press the preload inspection tool gradually by tightening the bolt (A) and fix it.
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).
NOTE: Measure the starting torque at normal room temperature in both directions.
Standard:
New Bearing:
10.98?13.59 N·m (112.0?138.6 kgf·cm, 97.2?120.3 lbf·in)
Reused Bearing:
9.53?12.14 N·m (97.2?123.8 kgf·cm, 84.3?107.4 lbf·in)
11.
If the measurement is out of the standard, remove the 51 mm thrust shim, and measure its thickness, then select a suitable 51 mm thrust shim.
NOTE:
To increase the starting torque, increase thickness of the 51 mm thrust shim.
To decrease the starting torque, decrease the thickness of the 51 mm thrust shim.
Do not use more than two thrust shims to adjust the starting torque.
