Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Lift the Vehicle

Use a hydraulic jack to lift the vehicle and support it securely with jack stands.
Remove the wheel(s) on the affected side to access the suspension components.

3. Inspect and Replace Damaged Components

Struts/Shocks:
- Remove the mounting bolts securing the strut/shock to the vehicle.
- If damaged, replace with OEM or aftermarket components.
Control Arms:
- Check the bushings for wear; replace if cracked or torn.
- Remove the control arm by unbolting it from the frame and the steering knuckle if necessary.
- Install the new control arm and torque bolts to the manufacturer's specifications.
Sway Bar Links:
- Inspect sway bar links for wear; replace if bushings are degraded.
- Remove the old sway bar link using a socket set and replace with a new one.

4. Reassemble and Lower the Vehicle

Reattach the wheel(s) and lower the vehicle carefully.
Tighten all fasteners to the specified torque values.
