Solution

1. Preparation

Gather tools and safety equipment.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Tire Inspection

Tools Required: Tire pressure gauge, visual inspection tools.
Check tire pressure and inflate to manufacturer specifications if needed.
Inspect tire tread depth and look for signs of uneven wear.
Replace any damaged tires if necessary.

3. Wheel Bearing Inspection

Tools Required: Jack, jack stands, torque wrench.
Jack up the vehicle and secure with jack stands.
Grasp the wheel at the 12 and 6 o'clock positions and shake; any play indicates bearing issues.
If bearings are worn, remove the wheel and replace the wheel bearings.

4. Brake Component Inspection

Tools Required: Socket set, torque wrench.
Remove the wheel to access the brake components.
Inspect brake pads for thickness; replace if below the recommended thickness.
Check the brake rotors for warping or scoring; resurface or replace if necessary.

5. Suspension Component Inspection

Tools Required: Visual inspection tools (flashlight, mirror).
Inspect all suspension components (bushings, control arms, struts) for signs of wear or damage.
Tighten any loose bolts and replace any damaged parts as needed.
