Wheel Bearings Adjustment

Raise and support vehicle. Ensure parking brake is fully released. Remove wheel and dust cap. Rotate brake drum and ensure there is no brake drag. Using a small cape chisel, raise the staked portion of the lock nut. Remove and discard lock nut.
NOTE: Right side lock nut has left-hand threads. Left side lock nut has right-hand threads.
Install new lock nut. To seat bearings, use a torque wrench and tighten lock nut to 18-22 ft. lbs. (25-29 N.m) while rotating brake drum. After tightening, loosen lock nut until it can be turned by hand. Measure seal drag using an INCH lb. torque wrench on a lug nut at 12 o'clock position. Measure and record amount of force required to rotate brake drum.
To determine preload, add amount of seal drag to specified preload of 1.3-4.3 INCH lbs. (.15-.49 N.m). As an example, if seal drag measures 2.2 INCH Lbs. (.25 N.m), this amount must be added to required preload.
Tighten wheel bearing lock nut a small amount. Using an INCH lb. torque wrench on a lug nut at 12 o'clock position, measure amount of pull required to rotate brake drum. Tighten attaching nut until specified amount of preload is measured with torque wrench. Stake lock nut with a blunt chisel. Install grease cap and wheel.

NOTE: Nut must be replaced if lock flange splits or cracks during staking process. Do not stake with a sharp edged tool.
