Removal Procedure

  1. Use a siphon in order to remove the power steering fluid from the power steering fluid reservoir.

  2. Object Number: 328680  Size: SH
  3. Loosen the power steering gear outlet hose clamp at the intermediate outlet pipe (14).
  4. Notice: Do not start the vehicle with any power steering gear inlet or outlet hoses disconnected. When disconnected, plug or cap all openings of components. Failure to do so could result in contamination or loss of power steering fluid and damage to the system.

    Important: The power steering gear outlet pipe includes the pipe that attaches to the steering gear and the hose that attaches to the intermediate outlet pipe.

  5. Remove the hose portion of the power steering gear outlet pipe (2) from the intermediate outlet pipe (14).
  6. Remove the power steering gear outlet pipe from the steering gear (7).

Installation Procedure


    Object Number: 328680  Size: SH

    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.

    Notice: The inlet and outlet hoses must not be twisted during installation. Do not bend or distort the inlet or outlet hoses to make installation easier. Failure to follow these procedures could result in component damage.

  1. Install the power steering gear outlet pipe (2) to the steering gear (7).
  2. Tighten
    Tighten the pipe fitting to 13 N·m (9 lb ft).

  3. Install the hose portion of the power steering gear outlet pipe (2) to the intermediate outlet pipe (14). Secure with the hose clamp.
  4. Notice: When adding fluid or making a complete fluid change, always use the proper power steering fluid. Failure to use the proper fluid will cause hose and seal damage and fluid leaks.

  5. Fill the power steering fluid reservoir. Refer to Checking and Adding Power Steering Fluid .
  6. Notice: If the power steering system has been serviced, an accurate fluid level reading cannot be obtained unless air is bled from the steering system. The air in the fluid may cause pump cavitation noise and may cause pump damage over a period of time.

  7. Bleed the power steering system. Refer to Power Steering System Bleeding .
