Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery for safety.

2. Inspect Tires

Tools Required: Tire pressure gauge, tread depth gauge.
Check tire pressure and inflate to the manufacturer's recommended PSI.
Measure tread depth; replace tires if they are worn beyond safety limits.

3. Check Drivetrain Fluid

Tools Required: Fluid catch pan, wrench set, funnel.
Locate the drivetrain fluid reservoir.
Remove the fill plug and check fluid level; add manufacturer-recommended fluid if low.
Inspect the fluid for contamination or burning smell; replace if necessary.

4. Examine Wheel Bearings

Tools Required: Jack stands, socket set, torque wrench.
Lift the vehicle and remove the wheel.
Check for play in the wheel hub by moving it side-to-side.
If excessive play is detected, replace the wheel bearings.

5. Test Drive

Reassemble any removed components.
Conduct a test drive to replicate the whining noise.
Monitor for changes in noise or handling characteristics.
