Power Steering Gear Inlet Hose With Vacuum Brake Booster

Removal Procedure

  1. Install a drain pan under the vehicle.
  2. Siphon the power steering fluid from the reservoir to prevent excessive spillage.

  3. Object Number: 309298  Size: SH
  4. Remove the power steering inlet hose (2) from the steering pump (1).

  5. Object Number: 309302  Size: SH
  6. Remove the steering gear inlet hose (1) from the steering gear (2).
  7. Remove the hose from the vehicle.

Installation Procedure

    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. Route the hose in the same position the hose occupied prior to removal.
  2. Smoothly route the hose in order to avoid sharp bends and kinking.
  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.
