A/T Differential Carrier Bearing Preload Inspection

A/T Differential Carrier Bearing Preload Inspection

Special Tools Required

- Bearing Driver Attachment, 78 x 80 mm 07NAD-PX40100
- Preload Inspection Tool 070AJ-0020101
- Bearing Driver Attachment, 72 x 75 mm 07746-0010600
- Driver Handle, 15 x 135L 07749-0010000

NOTE:

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

1. Remove the bearing outer race (A), the 76.2 mm spacer (B), and the 76 mm thrust shim (C) from the transmission housing (D) by heating the housing to about 212 °F (100 °C) using a heat gun (E). Do not heat the housing more than 212 °F (100 °C).

NOTE: Let the transmission housing cool to room temperature before adjusting the bearing preload.






2. 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.





3. Install the 76.2 mm spacer (C) and the bearing outer race (D) in the transmission housing.

NOTE: Be sure to install the 76.2 mm spacer with the "41382 RKY" mark facing downward.

4. Drive the bearing outer race securely in the transmission housing using the driver handle (15 x 135L) and the attachment (78 x 80 mm) so there is no clearance between the outer race, the spacer, the shim, and the transmission housing.






5. Install the differential assembly (A) in the torque converter housing (B).





6. Install the three dowel pins (C) and the gasket (D) on the torque converter housing.

7. Align the spring pin (E) of the selector control shaft (F) with the transmission housing groove (G) by turning the selector control shaft. Do not squeeze the end of the selector control shaft tips together when turning the selector control shaft.

8. Place the transmission housing (H) on the torque converter housing.

9. Install the transmission housing mounting bolts (K24Z6 engine 2WD: 19 bolts, except K24Z6 engine 2WD: 20 bolts) along with the transmission hanger (I) and the harness clamp brackets (J) (K24Z1 engine). Tighten the mounting bolts to 44 Nm (4.5 kg-m, 33 lb-ft) in two or more steps in a crisscross pattern.

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

11. 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.










12. If the starting torque is out of the standard, remove the 76 mm thrust shim and select a 76 mm thrust shim from the following table. Install a new thrust shim and recheck. To increase the starting torque, increase the thickness of the 76 mm thrust shim. To decrease the starting torque, decrease the thickness of the 76 mm thrust shim. Changing the 76mm thrust shim to the next size will increase or decrease starting torque about 0.3-0.4 Nm (3-4 kg.cm, 2-3 lbf.in).
