Solution

1. Preparation

• Gather necessary tools and parts.
• Park the vehicle on a flat surface and engage the parking brake.
• Wear safety gloves and goggles.

2. Inspect Power Steering Fluid

• Sub-steps:
  • Locate the power steering fluid reservoir.
  • Check the fluid level; if low, top off with the correct type of fluid (check owner's manual for specifications).
  • Inspect fluid for contamination (milky appearance or debris).

3. Check for Leaks

• Sub-steps:
  • Visually inspect power steering hoses and connections for leaks.
  • Look underneath the vehicle for puddles or drips.
  • Wipe off any suspected areas and monitor for fresh leaks after a short drive.

4. Examine Steering and Suspension Components

• Sub-steps:
  • Safely lift the front of the vehicle using a jack and secure with jack stands.
  • Inspect the steering rack for damage or signs of wear.
  • Check tie rod ends for play or excessive wear.
  • Inspect control arms and bushings for cracks or deterioration.

5. Test and Replace Steering Pump (if necessary)

• Sub-steps:
  • Start the engine and listen for noise from the power steering pump.
  • If noise persists, use a multimeter to check for electrical issues (if applicable).
  • Remove the old pump by disconnecting hoses and mounting bolts.
  • Install the new pump and ensure all connections are secure.
