3. Check Power Steering System

Sub-steps:
1. Locate the power steering fluid reservoir and check the fluid level; refill if low with the recommended power steering fluid.
2. Inspect the power steering pump and hoses for any signs of leakage or damage.
3. If a leak is found, replace the affected hoses or the pump as necessary.

4. Inspect and Lubricate Steering Components

Sub-steps:
1. Examine the steering rack for any visible damage or unusual play.
2. If components appear worn, replace them as necessary.
3. Apply a suitable lubricant to any exposed parts of the steering mechanism.

5. Reassemble and Test

Sub-steps:
