  • Shop towels

Repair Instructions:

  1. Locate the Leak: If a leak is found, trace it back to the source (hoses, connections, or steering rack).
  2. Replace Damaged Components:
    • If hoses are damaged, disconnect the old hose using a wrench and replace it with a new one.
    • Ensure that all connections are secured and retighten to the manufacturer’s torque specifications.
  3. Replenish Fluid: Fill the power steering fluid reservoir with the recommended fluid.
  4. Bleed the System: Start the engine, turn the steering wheel from lock to lock several times to help bleed air from the system.
2. Steering Wheel Vibration
Tools Required:
  • Tire pressure gauge
  • Alignment tools
  • Tire balancing equipment

Repair Instructions:

  1. Tire Maintenance:
    • Inflate tires to the recommended pressure.
    • Rotate tires if uneven wear is detected.
    • Balance tires if vibration persists after inflation and rotation.
  2. Alignment Adjustment:
    • If misalignment is found, use an alignment tool to adjust the camber, caster, and toe settings to factory specifications.
    • A professional alignment service may be necessary.
  3. Suspension Repairs: Replace any worn or damaged suspension components.
3. Steering Wheel Play or Looseness
Tools Required:
  • Socket set
  • Wrench set
  • Steering wheel puller (if necessary)

Repair Instructions:

  1. Tighten Loose Bolts: Use appropriate sockets/wrenches to tighten any loose bolts found in the steering linkage.
  2. Replace Worn Components:
    • If excessive wear is found in tie rods or the rack-and-pinion, disconnect the faulty components and replace with new ones.
    • Ensure proper installation following manufacturer torque specifications.
  3. Reassemble Steering Wheel: If the steering wheel was removed, reassemble it correctly, ensuring it is centered.
4. Electronic Power Steering Malfunction
Tools Required:
  • OBD-II scanner
  • Multimeter
  • Basic hand tools

Repair Instructions:

  1. Clear Error Codes: If codes are present, clear them and see if they return after a test drive.
  2. Repair Wiring Issues: If any damaged wires or connectors are found, repair or replace as necessary.
  3. Replace EPS Motor: If the EPS motor is faulty, disconnect it and replace it with a new unit, ensuring all connections are secure.
  4. Recheck System: After repairs, recheck the system for proper operation and ensure no warning lights remain on the dashboard.
