Solution

1. Preparation

Gather tools: socket set, torque wrench, fluid catch pan, power steering fluid.
Ensure the vehicle is on a flat surface and the engine is off.
Disconnect the battery for safety.

2. Inspect and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; it should be between the minimum and maximum marks.
If low, add the manufacturer-recommended power steering fluid to the appropriate level.
Replace the cap securely.

3. Check for Leaks

Inspect all hoses connected to the power steering system for signs of wear or leaks.
Look for fluid pooling under the vehicle, especially near the steering rack and pump.
If leaks are found, replace the affected hoses or components.

4. Inspect Steering Components

Lift the vehicle using a jack and secure it with jack stands.
Check the tie rods and ball joints for play or damage; grasp them and attempt to move them side to side.
If excessive play is detected, replace the worn components.

5. Check the Serpentine Belt

Inspect the serpentine belt for cracks, fraying, or significant wear.
If damaged, replace the serpentine belt according to the manufacturer’s specifications.
Ensure the belt is properly tensioned.

6. Reassemble and Torque Components

Reattach any components that were removed or loosened during inspection.
Torque all bolts to the manufacturer's specifications using a torque wrench.
