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 if working on electrical components.

2. Check Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; top off with the recommended fluid if low.
Inspect fluid condition; if dark or contaminated, consider a fluid flush.

Raise the front of the vehicle using a jack and secure with jack stands.
Check for leaks around the power steering pump, hoses, and steering rack.
Examine the steering linkage for any signs of wear or damage.

4. Tire Inspection

Inspect tires for uneven wear patterns.
Check tire pressures and inflate them to the manufacturer's specifications.
Rotate tires if necessary to ensure even wear.

5. Suspension Component Check

Inspect suspension components, including control arms, ball joints, and tie rods for damage or excessive wear.
Replace any damaged components as needed.

6. Reassemble and Test
