Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, pry bar, and a rubber mallet.
Safety Warnings: Ensure the vehicle is on a flat surface and securely supported by jack stands before starting work.

2. Remove and Inspect Components

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the wheel using a socket set.
3. Inspect struts and shocks for leaks or damage. If any are found, they will need to be replaced.
4. Use a pry bar to check for excessive play in the control arms and bushings.
5. Examine the sway bar links for signs of wear or damage.

3. Replace Worn Components

Sub-steps:
1. If struts or shocks are worn, remove them from the vehicle by unbolting them from their mountings.
2. Install new struts or shocks, ensuring to torque the bolts to manufacturer specifications (usually around 30-50 ft-lbs).
3. Replace any damaged bushings or sway bar links, ensuring they are seated properly and torqued to specification.
4. Reinstall the wheel and lower the vehicle to the ground.

4. Alignment Check

Sub-steps:
1. After replacing components, take the vehicle to a professional alignment shop to ensure proper wheel alignment.
2. Verify that all suspension components are functioning correctly.
