Total Bearing Preload

With differential fully assembled, without oil seals, install Wrench (07LLA-SM40200) for 1991 models or (07MAA-SF10100) for 1992 models in differential assembly. See Figure .
Rotate ring gear one full revolution in both directions while applying resistance to pinion shaft. Remove wrench from differential assembly.

Install a dial-type INCH-lb. torque wrench on the end of the drive pinion. Rotate drive pinion and note total bearing preload. Total bearing preload should be within specification. Refer to the TOTAL BEARING PRELOAD SPECIFICATIONS table below.

TOTAL BEARING PRELOAD SPECIFICATIONS

Application			INCH Lbs. (N.m)
New Bearings
All New Bearings			26-34 (2.9-3.8)
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			21-27 (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.
