Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Gather safety gear such as gloves and safety glasses.

2. Inspect Tires

Sub-steps:
- Check tire pressure using a tire gauge; inflate to manufacturer specifications if needed.
- Inspect tread depth and look for signs of uneven wear; replace tires if they are worn beyond safe limits.
- Rotate tires if uneven wear is detected to ensure even contact.

3. Check Wheel Balance

Sub-steps:
- Remove the wheel from the vehicle using a socket set.
- Place the wheel on a wheel balancer and spin to identify any imbalances.
- Add wheel weights as necessary to achieve balance.
- Reinstall the wheel and torque to manufacturer specifications (typically 80-100 ft-lbs).

4. Perform Wheel Alignment

Sub-steps:
- Use a laser alignment machine to check the alignment of the front wheels.
- Adjust toe, camber, and caster angles as needed to meet manufacturer specifications.
- Test drive to ensure alignment is correct and steering is straight.

5. Inspect Suspension Components

Sub-steps:
- Visually inspect components such as control arms, tie rods, and bushings for wear or damage.
- Replace any worn or damaged suspension parts.
- Perform a final test drive to ensure the shaking has been resolved.
