Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and turn off the ignition.
Wear safety gloves and glasses.

2. Inspect and Replace Tires (if necessary)

Sub-steps:
1. Remove the wheel covers, if applicable.
2. Loosen the lug nuts with a lug wrench slightly before lifting the vehicle.
3. Lift the vehicle using a jack and secure it with jack stands.
4. Fully remove the lug nuts and take off the tires.
5. Inspect tires for signs of uneven wear or damage. Replace if necessary.
6. Install new tires (if applicable) and torque lug nuts to manufacturer's specifications (typically 100-120 Nm).

3. Suspension Inspection and Repair

Sub-steps:
1. Check all suspension components (shocks, struts, control arms) for wear or damage.
2. Replace any damaged components as necessary.
3. Ensure all bolts are torqued to manufacturer specifications.

4. Wheel Alignment

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Ensure that the alignment is adjusted according to the manufacturer's specifications (usually around 0° camber and toe settings).

5. Final Check

Sub-steps:
1. Reinstall the tires if they were removed.
2. Perform a test drive to confirm that the shaking has been resolved.
