Solution

1. Preparation

Gather necessary tools and parts for inspection and potential replacement.
Ensure the vehicle is parked on a flat surface and secure with wheel chocks.
Disconnect the battery to ensure safety while working on the vehicle.

2. Inspect and Replace Suspension Components

Lift the Vehicle:
- Use a hydraulic jack and jack stands to lift the vehicle securely.
- Safety Warning: Ensure the vehicle is on a stable surface and properly supported by jack stands before working underneath.
Inspect Struts and Shocks:
- Remove the wheel to access the strut assembly.
- Check for signs of fluid leakage or physical damage.
- If damaged, proceed to remove the strut assembly using a socket set (typically 10-19mm depending on model).
- Replace with OEM or high-quality aftermarket struts/shocks.
Check Sway Bar Links and Bushings:
- Locate the sway bar and inspect the links and bushings for wear.
- Remove any worn components using a wrench and replace with new sway bar links and bushings.
Reassemble Components:
- Reinstall the struts and ensure all bolts are torqued to the manufacturer's specifications (usually between 50-70 ft-lbs).
- Reinstall the wheel and torque lug nuts to the recommended setting (typically 80-100 ft-lbs).
Lower the Vehicle:
- Carefully lower the vehicle back to the ground and reconnect the battery.
