Total Bearing Preload
- With differential fully assembled, without oil seals, install Wrench (07HAA-SF10100) in differential assembly. See Figure.
- Rotate ring gear one full revolution in both directions while applying resistance on drive pinion. Remove wrench from differential assembly.
- Install a dial-type INCH-lb. torque wrench on end of drive pinion. Rotate drive pinion several times and note total bearing preload. Total bearing preload should be within specification. See TOTAL BEARING PRELOAD SPECIFICATIONS table.TOTAL BEARING PRELOAD SPECIFICATIONS
Application Preload - INCH Lbs. (N.m) All New Bearings 25-33 (2.9-3.8) New Differential Carrier Bearings Only Outer Bearing (Ring Gear Side Only) 22-28 (2.5-3.2) Inner Bearing (Drive Pinion Side Only) 25-32 (2.8-3.6) Used Bearings 21-26 (2.4-3.0) - If total bearing preload is not within specification, increase preload by increasing thickness of thrust shim located below bearing races in differential case and differential case cover. Decreasing shim thickness will decrease total bearing preload.
NOTE:
Ensure thrust shim thickness is increased the same amount on both thrust shims.
