Solution

1. Preparation

Gather tools and necessary parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical shorts.

2. Inspect Power Steering System

Check Fluid Level: Open the power steering reservoir cap and inspect fluid level; top off with manufacturer-recommended fluid if low.
Inspect Hoses: Look for leaks or damage on power steering hoses.
Test Pump: If noise persists, remove the power steering pump and bench-test it to check for proper operation.

3. Inspect Serpentine Belt

Visual Inspection: Check for cracks, fraying, or glazing on the belt.
Tension Check: Ensure proper tension; use a belt tension gauge if necessary.
Replacement: If damaged, remove the belt by loosening the tensioner and replace with a new belt (make sure to note routing).

4. Check Transmission Fluid

Fluid Level: With the engine running, check the transmission fluid level using the dipstick; add fluid if low.
Fluid Condition: Inspect for a burnt smell or dark color; if fluid is dirty, consider a transmission fluid change.

5. Inspect Wheel Bearings

Jack Up Vehicle: Safely lift the vehicle and secure with jack stands.
Check for Play: Grab the wheel at 12 and 6 o'clock and wiggle; any play indicates bearing wear.
Replace Bearings: If faulty, remove the wheel and hub assembly, press out the old bearings, and press in new ones.

6. Check Differential

Fluid Level: Inspect the differential fluid level and top off if necessary.
Listen for Noise: While driving, note if the noise changes when turning, indicating potential issues with the differential gears.
