A/T Differential Carrier Bearing Preload Inspection

Special Tools Required
Handle driver (  07749-0010000)
 

Driver attachment, 72 x 75 mm (  07746-0010600)
 
Preload inspection tool (  07HAJ-PK40201)
 


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.
  • The illustration shows the 4WD model; 2WD is similar.

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 212°F (100°C) with heat gun (E). Do not heat the housing in excess of 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 new one, use the same thickness shim as the old one.

 

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

4.Drive the bearing outer race to install securely so there is no clearance between the outer race, thrust washer, shim and housing with the special tools.

 

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

 

6. Install the transmission housing (E) with the transmission hanger (F) and harness clamp brackets (G), then tighten the bolts.

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

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

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) 

 

9.If the measurement is out of standard, remove the thrust shim and select the thrust shim from table below. 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, 3-3 lbf·in).
