Solution

1. Preparation

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

2. Inspect Power Steering Fluid

Sub-steps:
1. Locate the power steering fluid reservoir.
2. Remove the cap and check the fluid level against the markings.
3. If the fluid is low, top it up with the manufacturer-recommended power steering fluid.

2. Clean any spilled fluid and monitor for reoccurrence.
3. Repair or replace any faulty hoses or seals as needed.

4. Test Power Steering Pump

Sub-steps:
1. With the engine on, listen for unusual noises from the pump.
2. Check for vibrations or excessive play in the pump pulley.
3. If the pump is faulty, replace it using a socket set and follow manufacturer specifications for torque.

5. Inspect Steering Rack and Components

Sub-steps:
1. Raise the vehicle and secure it with jack stands.
2. Inspect the steering rack for any leaks or physical damage.
3. Check for play in the tie rods and ensure they are securely fastened.
4. Replace any worn or damaged components.

6. Check Tire Pressure and Alignment
