Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety glasses and gloves.

2. Raise the Vehicle

Using a jack, lift the front or rear of the vehicle as needed, and secure it on jack stands.
Ensure the vehicle is stable before proceeding with any repairs.

3. Inspect and Replace Components

Sway Bar Links:
- Remove the bolts securing the sway bar links to the sway bar and lower control arm using a socket set.
- Replace with new sway bar links, tightening to the manufacturer's specified torque (usually around 40-50 ft-lbs).
Struts/Shocks:
- Remove the top nuts of the struts from under the hood.
- Remove lower bolts securing the strut to the knuckle.
- Replace with new struts or shocks and tighten to the manufacturer's specified torque (typically 80-90 ft-lbs for lower bolts).
Control Arms/Ball Joints:
- Remove the bolts securing the control arm and ball joint.
- Inspect the ball joint for wear and replace if necessary.
- Install new components and torque to specifications (usually 40-60 ft-lbs for control arm bolts).

4. Reassemble and Lower Vehicle

Reattach any components previously removed, ensuring all bolts are tightened securely.
Lower the vehicle from jack stands and remove the jack.
