Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery if working on electrical components.

2. Check and Top Off Power Steering Fluid

Locate the power steering fluid reservoir under the hood.
Remove the cap and check the fluid level; if low, add the appropriate type of power steering fluid as specified in the owner's manual.
Inspect the fluid for contamination; if dirty, it may require a flush.

3. Inspect Power Steering Pump

Remove any covers obstructing access to the power steering pump.
Check for signs of wear or leaks on the pump.
If the pump is noisy or leaking, replace it.

4. Inspect Steering Rack and Tie Rod Ends

Raise the front of the vehicle using a jack and secure it with jack stands.
Inspect the steering rack for any visible damage or leaks.
Check tie rod ends for play by moving them with your hands; replace if loose or damaged.

5. Lubricate or Replace Affected Components

If any joints (ball joints, tie rod ends) are worn, apply appropriate lubrication or replace the affected components.
If the steering column is producing noise, consider lubricating it or inspecting it for wear.

6. Reassemble and Test

Reattach any covers or components removed during inspection.
Reconnect the battery if it was disconnected.
Start the engine and test the steering by turning the wheel left and right.
