Solution

1. Preparation

Gather tools and safety equipment.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Fluid Inspection

Power Steering Fluid:
- Remove the power steering reservoir cap.
- Inspect fluid level; top off with the manufacturer-recommended power steering fluid if low.
- Check fluid condition; if dark or contaminated, a fluid change may be necessary.
Transmission Fluid:
- Check the transmission fluid level using the dipstick.
- If low, add the specified transmission fluid to the appropriate level.
- If fluid appears burnt or has metal shavings, consider a transmission service.

3. Component Inspection

Wheel Bearings:
- Raise the vehicle and secure it on jack stands.
- Spin each wheel; listen for grinding or roughness indicating bad bearings.
- If noise is present, replace the affected wheel bearing.
Drivetrain Components:
- Inspect driveshafts and CV joints for wear or damage.
- Check for any visible leaks around the differential or transmission.

4. Steering System Repair (if applicable)

If the power steering system is the source:
- Inspect hoses for leaks and replace if necessary.
- Replace the power steering pump if it is noisy or failing.

5. Reassembly and Testing

Reinstall any components removed during inspection.
Reconnect the battery.
Lower the vehicle and perform a test drive to confirm the issue is resolved.
