Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety goggles and gloves.

2. Inspect Brake Components

Remove Wheel
- Loosen lug nuts on the affected wheel.
- Lift the vehicle with a jack and secure it with jack stands.
- Remove the wheel.
Check Brake Rotor
- Inspect the rotor surface for warping or scoring.
- Use a dial indicator to measure rotor runout. If it exceeds manufacturer's specifications, replace the rotor.
Inspect Brake Pads
- Check the thickness of the brake pads. Replace if below the minimum thickness.
- Look for uneven wear patterns, which may indicate caliper issues.

3. Suspension Inspection

Examine Suspension Components
- Check tie rods, control arms, and bushings for cracks or excessive play.
- Replace any worn or damaged components.

4. Wheel Alignment and Balance

Check Alignment
- Measure wheel alignment using alignment equipment.
- Adjust as necessary to bring wheels to manufacturer specifications.
Balance Tires
- Inspect tire balance and adjust using wheel weights if necessary.

5. Reassemble and Test

Reinstall Wheel
- Place the wheel back on and hand-tighten lug nuts.
- Lower the vehicle and then torque lug nuts to manufacturer's specifications.
Test Drive
- Conduct a test drive to ensure the shaking has been resolved.
