Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, stethoscope, torque wrench
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical issues if necessary.

2. Tire Inspection

Sub-steps:
1. Remove the wheel covers if applicable.
2. Inspect each tire for uneven wear, bulges, or foreign objects lodged in the tread.
3. Rotate the tires if uneven wear is noticed, and replace if necessary.

3. Brake Component Inspection

Sub-steps:
1. Remove the wheel to access the brake assembly.
2. Inspect brake pads for wear; replace if thickness is less than 3mm.
3. Check rotors for warping or grooves; replace if necessary.
4. Reinstall the wheel and torque to manufacturer specifications.

4. Wheel Bearing Check

Sub-steps:
1. Lift the vehicle and secure it on jack stands.
2. Grasp the tire at the 12 and 6 o'clock positions and wiggle; check for play.
3. If play is detected, remove the wheel and replace the wheel bearing as needed.

5. Suspension Component Check

Sub-steps:
1. Inspect the shocks and struts for leaks or damage.
2. Check all bushings for wear or deterioration.
3. Tighten or replace any loose or damaged components.
