    2. • Cracks
    • Dents
    • Damage to the threads
  2. Replace the parts as needed.

    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.

  5. Install the cylinder line assemblies (1) to the gear assembly (2).

    6. Important: Flush and bleed power steering system (hoses, reservoir and cooler lines) with power steering fluid GM P/N 1050017 (or equivalent meeting GM Specification number 9985010).

    Tighten

    • Tighten the valve end fittings to 16.9 N·m (12.6 lb ft).
