Installation Procedure

CAUTION: If a clamp-type pitman arm is used, spread the pitman arm just enough with a wedge to slip the arm onto the pitman shaft. Do not spread the pitman arm more than required to slip over the pitman shaft with hand pressure. Do not hammer. Damage to the steering gear may result.

Install the pitman arm on the pitman shaft.
Line up the marks made at removal.

Use a new torque prevailing nut.

CAUTION: 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 of 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.
Install the pitman arm washer and nut.
