Power Steering Gear Inlet Hose With Vacuum Brake Booster

Notice: Refer to Power Steering Hose Disconnected Notice in the Preface section.

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.

Removal Procedure


    Object Number: 245030  Size: LH
  1. Install a drain pan under the vehicle.
  2. Siphon the power steering fluid from the reservoir to prevent excessive spillage.
  3. Remove the power steering gear inlet hose (4) from the power steering gear.
  4. Remove the power steering gear inlet hose (4) from the power steering pump.
  5. Remove the power steering gear inlet hose from the vehicle.

Installation Procedure


    Object Number: 245030  Size: LH
  1. Route the hose in the same position the hose occupied prior to removal.
  2. 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.

  3. Install the power steering gear inlet hose (4) to the power steering pump.
  4. Tighten
    Tighten the power steering gear inlet hose (4) at the power steering pump to 27 N·m (20 lb ft).

  5. Install the power steering gear inlet hose (4) to the power steering gear.
  6. Tighten
    Tighten the power steering gear inlet hose (4) at the power steering gear to 27 N·m (20 lb ft).
