Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure safety gear is worn, including gloves and safety glasses.

2. Tire Pressure Adjustment

Remove valve caps and check tire pressures using a tire pressure gauge.
Inflate or deflate tires to match the manufacturer's recommended pressures, typically found on the driver’s door jamb sticker.

3. Wheel Balancing

Remove the front wheels using a socket set.
Mount each wheel on the wheel balancer and spin to check for imbalance.
Add wheel weights as necessary to achieve balance, ensuring they are secured properly.

4. Suspension Inspection

Raise the vehicle using a jack and secure it with jack stands.
Inspect tie rods for play by pulling and pushing on the connection points.
Check control arms and bushings for cracks or excessive wear.
Replace any damaged components with OEM parts as needed.

5. Wheel Alignment

Align the vehicle using a professional alignment rack.
Adjust toe, camber, and caster angles according to manufacturer specifications.
Tighten all suspension components to specified torque values.

6. Reinstallation and Final Check

Reinstall the front wheels and torque to the manufacturer's specifications (usually 90-120 Nm).
Lower the vehicle and take it for a test drive to ensure the shaking is resolved.
