Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, stethoscope.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Raise the Vehicle

Loosen the lug nuts on the wheels slightly while the vehicle is on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheels to gain access to the suspension components.

3. Inspect Suspension Components

Check the condition of the shocks/struts for leaks or damage.
Inspect the sway bar links and bushings for wear; replace if cracked or loose.
Tighten any loose bolts or fasteners found during the inspection to the manufacturer's specifications.

4. Replace Worn Components

If a shock or strut is found to be damaged, remove the retaining bolts and disconnect the component.
Install a new shock/strut, ensuring it is oriented correctly, and torque the bolts to the manufacturer's specification.
If sway bar links or bushings are worn, remove the old components and install new ones, torquing them to specification.

5. Reassemble and Lower Vehicle

Reinstall the wheels and torque the lug nuts to the specified value.
Carefully lower the vehicle back to the ground and remove the jack stands.
