why does my Porsche Cayenne E3 (2018-Present) make a loud noise over bumps

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is turned off.
• Use wheel chocks to prevent vehicle movement.

2. Lift the Vehicle

• Use a hydraulic jack to lift the vehicle and secure it with jack stands.
• Remove the front or rear wheels depending on where the noise is suspected to originate.

3. Inspect Suspension Components

• Shocks/Struts: Remove any protective covers if applicable. Check for oil leakage and compress the shock to see if it rebounds smoothly.
• Control Arms and Bushings: Visually inspect for cracks and excessive play. If damaged, replace the control arms or bushings.
• Bolts and Fasteners: Tighten any loose bolts to the manufacturer’s torque specifications. Replace any missing or damaged bolts.

4. Replace Worn Components

• If shocks or struts are found to be leaking or ineffective, proceed to remove the old components:
  • Remove Shock Absorbers: Unbolt the top and bottom mounts. Replace with new shocks, ensuring to torque bolts to specifications.
  • Control Arm Replacement: If necessary, unbolt the control arm from the frame and lower ball joint. Replace with a new control arm and torque to specifications.

5. Reassemble and Lower Vehicle

• Reattach wheels and lower the vehicle back to the ground.
• Recheck all fasteners and components for tightness.

6. Test Drive

• Conduct a test drive to ensure the noise has been eliminated and that the ride quality is restored.
