Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface, engage the parking brake, and turn off the ignition.
Wear safety gloves and goggles.

2. Inspect Power Steering Fluid

Sub-steps:
- Locate the power steering fluid reservoir.
- Check the fluid level against the markings on the reservoir.
- If low, add the recommended power steering fluid (usually ATF or specific power steering fluid).
- Inspect the fluid condition; if dark or contaminated, a fluid change is needed.

3. Check for Leaks

Sub-steps:
- Inspect all hoses connected to the power steering system for cracks, wear, or leaks.
- Examine the steering rack for any signs of fluid leakage.
- Clean the area around the power steering system to identify fresh leaks.

4. Test Power Steering Pump

Sub-steps:
- Disconnect the power steering pump and install a pressure gauge in the outlet line.
- Start the engine and turn the steering wheel to check for proper pressure readings (consult manufacturer specs for correct values).
- If readings are below specifications, replace the power steering pump.

5. Examine Steering Column and Linkage

Sub-steps:
- Remove any covers around the steering column for access.
- Inspect the steering shaft for binding or obstruction.
- Ensure all connections are tight and free of rust or corrosion.

6. Check Tire Pressure

Sub-steps:
- Use a tire pressure gauge to check each tire's pressure.
- Inflate tires to the manufacturer's recommended pressure (found on the driver’s side door jamb).
