A/T Differential Carrier Bearing Preload Inspection

A/T Differential Carrier Bearing Preload Inspection

Special Tools Required

- Driver handle, 15 x 135L 07749-0010000
- Attachment, 83 mm 07HAD-SG00100
- Preload inspection tool 070AJ-0020101
NOTE:

- If the transmission housing, the torque converter housing, the differential carrier, the tapered roller bearing, the bearing outer race, or the 85 mm thrust shim were replaced, the bearing preload must be adjusted.

- Replace the tapered roller bearing when the bearing outer race is replaced.

- Do not use a shim on the torque converter housing side.

- Coat all parts with ATF during installation.

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) using 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. 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.

3. Install the spacer (C) and the bearing outer race (D) in the transmission housing.






4. Drive the bearing outer race securely in the transmission housing using the driver handle and the 83 mm attachment so there is no clearance between the bearing outer race, the spacer, the 85 mm thrust shim, and the transmission housing.






5. 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.

6. Install the transmission housing (E), and install the mounting bolts (with SH-AWD: 24 bolts, without SH-AWD: 23 bolts) with the transmission hanger (F) and the ground terminal bracket (G), then tighten the bolts to the specified torque.

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






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

Standard
New Bearing:
3.9-5.1 N-m (40-52 kgf-cm, 35-45 lbf-in.)
Reused Bearing:
3.6-4.8 N-m (37-49 kgf-cm, 32-43 lbf-in.)

9. If the starting torque is out of the standard, remove the 85 mm thrust shim and select a new 85 mm thrust shim from the following table. Install a new 85 mm thrust shim, and recheck. 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.)
