Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, dial indicator, torque wrench, brake cleaner, and a basic socket set.
Safety Warnings: Ensure the vehicle is on a flat surface and securely supported with jack stands before working underneath it.

2. Remove Wheel

Loosen lug nuts on the affected wheel slightly.
Use a jack to lift the vehicle and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect Brake Components

Brake Rotors:
- Use a dial indicator to measure rotor runout. If the runout exceeds manufacturer specifications, the rotor needs resurfacing or replacement.
Brake Pads:
- Check the thickness of the brake pads. Replace if they are below the minimum thickness.
- Inspect for uneven wear; if present, replace pads.

4. Check Suspension and Wheel Bearings

Examine the suspension components for any signs of wear or damage.
Check wheel bearings by gripping the wheel at the 12 and 6 o'clock positions and shaking. Any play indicates a need for replacement.

5. Reassemble and Torque

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands.
Use a torque wrench to tighten the lug nuts to the manufacturer's specified torque.
