Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery if working on electronic components.

2. Inspect and Replace Worn Suspension Components

Tools Required: Socket set, torque wrench, jack stands, and pry bar.
Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheels to gain access to the suspension components.
3. Inspect struts and shocks for leaks or physical damage; replace if necessary.
4. Check and replace worn bushings in control arms and sway bars.
5. Reassemble components and wheels, ensuring to torque the lug nuts to manufacturer specifications.

3. Check and Adjust Wheel Alignment

Tools Required: Alignment machine (if available) or tape measure, string.
Sub-steps:
1. If the suspension components were replaced, perform a wheel alignment using an alignment machine.
2. If an alignment machine is not available, use a tape measure to ensure the front wheels are parallel.
3. Adjust tie rods as necessary to achieve proper alignment specifications.

4. Test Drive

Drive the vehicle over various road conditions to verify the shaking is resolved.
