Solution

1. Preparation

• Tools Required: Jack and jack stands, OBD-II scanner, multimeter, fluid catch pan.
• Allow the engine to cool before starting any work.
• Ensure the vehicle is in a secure position on a level surface with the parking brake engaged.

2. Inspect and Address Power Steering System

• Sub-steps:
  1. Locate the power steering reservoir and check fluid levels; add fluid if low.
  2. Inspect the power steering pump for leaks or unusual wear.
  3. If the noise persists after fluid adjustments, consider replacing the power steering pump.

3. Examine the Serpentine Belt

• Sub-steps:
  1. Remove the serpentine belt by releasing tension with a belt tensioner tool.
  2. Inspect the belt for cracks, fraying, or signs of wear.
  3. If damaged, replace with a new serpentine belt, following the routing diagram in the engine bay.

4. Inspect Drivetrain Components

• Sub-steps:
  1. Lift the vehicle securely and remove the wheels if needed for better access.
  2. Check the differential and transmission fluid levels; replace fluids if contaminated or low.
  3. Inspect universal joints and CV joints for play or damage; replace if necessary.

5. Final Checks

• Reassemble any components removed during inspection and ensure all fasteners are torqued to manufacturer specifications.
• Lower the vehicle and perform a test drive to confirm the noise has been resolved.
