Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, pry bar, and a stethoscope or mechanic's listening device.
Ensure the vehicle is on a flat surface and securely raised with jack stands.
Wear safety glasses and gloves.

2. Inspect and Replace Worn Components

2.1. Check Struts/Shocks

Remove the wheel to access the strut assembly.
Use the socket set to unbolt the strut from the lower control arm and upper mounting points.
Inspect the strut for leaks or damage. If damaged, replace with a new shock absorber or strut assembly.
- Torque Specification: Tighten strut mounting bolts to manufacturer specifications.

2.2. Check Sway Bar Links

Inspect the sway bar links for wear or damage.
If worn, remove the link by unbolting it from both the sway bar and control arm.
Replace with new sway bar links and torque to specifications.

2.3. Check Control Arms and Bushings

Inspect control arms and their bushings for deterioration.
If bushings are cracked or worn, remove the control arm using the socket set and replace the bushings as necessary.
- Torque Specification: Reinstall control arms to manufacturer specifications.

3. Reassemble and Lower Vehicle

Reattach the wheel, ensuring all nuts are tightened to the specified torque.
Lower the vehicle back to the ground.
