Wheel Bearing Adjustment Grease Lubricated

Removal Procedure


    Object Number: 22035  Size: SH
  1. Raise the vehicle. Support the vehicle with suitable safety stands.
  2. Remove the bolts and the washers.
  3. Remove the hub cap and the gasket. Do not allow gasket material to fall into the hub.
  4. Remove the cotter pin.

Adjustment Procedure


    Object Number: 22036  Size: SH
  1. Tighten the adjusting nut while you rotate the wheel 360 degrees in both directions in order to correctly position the bearings.
  2. Tighten
    Tighten the adjusting nut to 153 N·m (113 lb ft).

    Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

    Important: Always back off the nut a minimum of 1/6 of a turn. This adjustment should result in bearing end play of 0.025-0.020 mm (0.001-0.008 in).

  3. Back off the nut 1/6 turn or more until the slot in the nut lines up with the hole in the spindle.

Installation Procedure


    Object Number: 22035  Size: SH
  1. Install the new cotter pin.
  2. Install the new gasket and the hub cap. Make sure the gasket is properly aligned.
  3. Install the bolts and the new washers.
  4. Tighten
    Tighten the bolts evenly to 13 N·m (115 lb in).

    Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener.
