Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, torque wrench, runout gauge, caliper tool.
Ensure the vehicle is on a flat surface and the parking brake is applied.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel completely.

3. Inspect Brake Components

Brake Pads:
- Visually inspect for thickness; replace if below manufacturer specifications (typically 3mm).
Brake Rotors:
- Use a runout gauge to check for warping; replace if runout exceeds specifications (usually 0.002 inches).
- If the rotor is within specifications but shows excessive wear or scoring, consider resurfacing or replacing.

4. Examine Suspension and Wheel Bearings

Check for any play in the wheel bearings by wiggling the wheel; replace if any movement is detected.
Inspect control arms, bushings, and other suspension components for cracks or wear; replace as necessary.

5. Reassemble and Torque

Reinstall the brake components, ensuring everything is properly aligned.
Replace the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (usually around 80-100 ft-lbs, depending on model).
