Power Steering Gear Inlet Hose With Vacuum Brake Booster

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.

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).

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

  7. Remove the drain pan from under the vehicle.
  8. Bleed the power steering system. Refer to Power Steering System Bleeding .
