    2. Important: Inspect the fastener for the following conditions:

       • The fastener and its counterpart are clean and free from rust.
       • The fastener develops 2 N·m (18 lb in) of torque (drag) against its counterpart prior to the fastener seating.
    If the fastener does NOT meet these criteria, REPLACE the fastener.

  2. Install the power steering gear bolts.

    3. 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.
