Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secured with wheel chocks.
Disconnect the battery if working with electronic suspension components.

2. Inspect and Replace Components

A. Struts/Shocks

Remove Wheel:
- Use a lug wrench to loosen and remove the wheel nuts.
- Remove the wheel to access the suspension components.
Remove Strut/Shock Assembly:
- Locate the upper and lower mounting bolts.
- Use a socket set to remove these bolts.
- Carefully detach the strut/shock assembly from the vehicle.
Inspect and Replace:
- Inspect the strut/shock for signs of leakage or damage.
- If damaged, install the new strut/shock by reversing the removal process.
- Torque the mounting bolts to manufacturer specifications (typically around 50-65 ft-lbs).

B. Sway Bar Links/Bushings

Access Sway Bar:
- Use a socket set to remove the sway bar link from its mounting points.
Inspect Links and Bushings:
- Check for wear or play in the sway bar links and bushings.
- Replace any worn components with new parts.

3. Reassemble and Test

Reinstall Wheel:
- Place the wheel back onto the hub and hand-tighten the lug nuts.
- Lower the vehicle and torque the lug nuts to specifications (typically around 76-85 ft-lbs).
Final Inspection:
- Double-check all connections and ensure that everything is secure.
- Reconnect the battery if it was disconnected.
