Solution

1. Preparation

Gather tools: jack, jack stands, tire pressure gauge, torque wrench, and stethoscope.
Park the vehicle on a level surface and engage the parking brake.
Ensure the engine is off and cool.

2. Tire Inspection

Sub-step 1: Check tire pressure using a tire pressure gauge and inflate to the manufacturer’s specifications if necessary.
Sub-step 2: Visually inspect the tires for signs of uneven wear, such as balding or cupping.
Sub-step 3: Rotate the tires if uneven wear is present and ensure proper alignment.

3. Wheel Bearing Inspection

Sub-step 1: Lift the front end of the vehicle using a jack and secure it with jack stands.
Sub-step 2: Grab each wheel at the 12 o’clock and 6 o’clock positions and rock it back and forth to check for play.
Sub-step 3: If play is detected, remove the wheel and inspect the wheel bearing hub assembly for wear or damage.

4. Driveshaft and CV Joint Inspection

Sub-step 1: Inspect the driveshaft for any visible signs of damage or leakage.
Sub-step 2: Check CV joints for torn boots or excessive play.
Sub-step 3: If any issues are found, replace the affected components.

5. Final Assembly and Testing

Sub-step 1: Reassemble all components securely and ensure all bolts are torqued to manufacturer specifications.
Sub-step 2: Lower the vehicle and perform a test drive to confirm the humming noise has been resolved.
