    Before servicing the vehicle, refer to the Precautions Section.
    Drain the axle housing fluid.
    Remove or disconnect the following:

    Rear wheels
    Driveshaft
    Brake calipers and pads or brake drum

    NOTE
    The brake calipers and pads or brake drum must be removed so that there is no additional drag when measuring pinion bearing preload.

    Use an inch lb. torque wrench and measure and record the amount of torque required to maintain pinion rotation through several revolutions.

    Remove or disconnect the following:
    Pinion flange
    Pinion seal
    Pinion bearing
    Collapsible spacer

    To install:
    NOTE
    Use a new collapsible spacer and flange nut for assembly.
    Install or connect the following:
    Collapsible spacer
    Pinion bearing
    Pinion seal
    Pinion flange

    Rotate the pinion flange occasionally while tightening the flange nut to make sure the pinion bearings seat correctly.
    Take frequent bearing preload torque readings. Tighten the flange nut to achieve the preload torque readings originally recorded.

    CAUTION
    Never loosen the pinion nut to reduce bearing preload. If it is necessary to reduce bearing preload, install a new collapsible spacer and pinion nut.
    Install or connect the following:

    Driveshaft
    Brake calipers and pads or brake drum
    Wheels
    Fill the differential with gear lubricant and check for leaks.
