Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery for safety, especially if working on electronic suspension components.

2. Inspect and Replace Shocks/Struts

Tools Required: Socket set, torque wrench, jack stands, floor jack, impact wrench (optional).
Remove the wheel on the affected corner to access the suspension.
Inspect the shocks/struts for fluid leakage or physical damage.
If replacement is necessary, unbolt the top and bottom mounts of the shock/strut assembly.
Carefully remove the assembly from the vehicle.

3. Install New Shocks/Struts

Align the new shock/strut assembly in place.
Secure the top and bottom mounts to the specified torque settings (refer to the service manual for exact values).
Reinstall the wheel and lower the vehicle back to the ground.

4. Check and Replace Sway Bar Links/Bushings (if needed)

Tools Required: Wrench set, possibly a ball joint separator.
Inspect sway bar links and bushings for wear.
If replacement is needed, remove the old links by unbolting them from the sway bar and the control arm.
Install new sway bar links and bushings, ensuring they are secured properly.

5. Final Inspection

Recheck all fasteners and suspension components for tightness.
Lower the vehicle and perform a bounce test again to ensure the noise has been eliminated.
