Assembly Procedure






Important: Note the orientation of the variable assist steering actuator discharge fitting.

1. Lubricate and install the new O-ring seal with power steering fluid.

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.

2. Install the variable assist steering actuator (1) to the pump assembly.

Tighten
Tighten the actuator to 62 Nm (46 lb ft).

3. Install the negative battery cable.

Important: If a new variable assist steering actuator (1) is being installed, position the electrical connector before installing the retaining ring (2).

4. Install the electrical connector to the variable assist steering actuator (1).
5. Install the retaining ring (2) to the variable assist steering actuator (1).
