Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent accidental electrical shorts.

2. Check and Replenish Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; add the appropriate power steering fluid if low.
Inspect the fluid for contamination; if dirty, proceed to change the fluid.

3. Inspect and Repair Leaks

Use a clean rag to wipe around the steering rack and hoses.
If leaks are identified, replace the faulty hose or steering rack.
Tighten any loose connections to prevent further leaks.

4. Replace or Repair Steering Components

If noise persists, remove the steering linkage using a socket set.
Inspect tie rod ends and ball joints for wear; replace if necessary.
If the power steering pump is faulty, remove it by unbolting it from its mount and disconnecting the hoses. Install a new pump and refill fluid.

5. Reassemble and Reconnect

Reattach the steering linkage and ensure all bolts are tightened to manufacturer torque specifications.
Reconnect the battery and check for any warning lights on the dashboard.
