Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, pry bar, stethoscope or listening device.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery if necessary for electrical components.

2. Remove and Inspect Components

Control Arms:
1. Remove the wheel for access.
2. Unbolt the control arm from the subframe and the steering knuckle using the socket set.
3. Inspect bushings for wear and replace if cracked or torn.
Struts:
1. Unbolt the strut assembly from the steering knuckle and the upper mount.
2. Inspect for leaks or physical damage; replace if necessary.
Sway Bar Links:
1. Remove the sway bar link bolts using the socket set.
2. Inspect for wear and replace if the bushings are cracked or the link is bent.

3. Reassemble and Torque

Reinstall all components in reverse order, ensuring each bolt is torqued to the manufacturer's specifications found in the service manual.
Torque Values: Refer to the vehicle service manual for specific torque values for each component.
