Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during inspection.

2. Tire Inspection

Tools Required: Tire pressure gauge, jack, jack stands.
Remove the tire using a lug wrench.
Inspect tread depth and look for any irregularities or debris.
Check the sidewalls for bulges or cuts.
Reinstall the tire and lower the vehicle if no issues are found.

3. Wheel Bearing Examination

Tools Required: Socket set, torque wrench.
Remove the wheel and brake caliper to access the hub assembly.
Check for any play in the wheel bearing by shaking the hub; it should not move excessively.
If play is detected, replace the wheel bearing as per the manufacturer’s specifications. Torque the bearing to the specified value upon installation.

4. Drivetrain Inspection

Tools Required: Socket set, pry bar.
Inspect the driveshaft and CV joints for any grease leakage or visible damage.
Rotate the driveshaft by hand; listen for any grinding or unusual noises.
Replace any damaged components as necessary.

5. Suspension Check

Tools Required: Wrench set, flashlight.
Inspect suspension components, including struts, shocks, and control arms, for wear or damage.
Look for any broken or loose parts that may contribute to noise.
Replace worn or damaged suspension components.
