Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a flat, stable surface and engage the parking brake.
Disconnect the battery if working on electronic suspension systems.

2. Lift the Vehicle

Use a hydraulic jack to lift the vehicle and secure it with jack stands.
Remove the wheels for better access to the suspension components.

3. Inspect and Replace Components

Struts and Shocks:
- Inspect for leaks and physical damage.
- If damaged, remove the strut assembly using a socket set, replace with new struts, and tighten to the manufacturer's torque specifications (usually around 50-60 ft-lbs).
Sway Bar Links and Bushings:
- Remove the sway bar links by loosening the bolts with a socket set.
- Replace worn sway bar links and bushings with new parts, ensuring proper alignment during installation.
Control Arm Bushings:
- Inspect control arm bushings for cracking or separation.
- If damaged, replace them by removing the control arm, replacing the bushings, and re-installing the control arm with the correct torque.

4. Reassemble and Lower Vehicle

Reattach the wheels and lower the vehicle.
Tighten lug nuts to the manufacturer’s specifications (typically 75-85 ft-lbs).

5. Final Inspection

Recheck all replaced components visually to ensure everything is installed correctly.
Reconnect the battery if it was disconnected.
