why does my Genesis G70 have a rattling noise when going over bumps?

Solution

1. Preparation

• Gather tools and parts needed for repair.
• Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
• Disconnect the battery to avoid electrical issues during repairs if necessary.

2. Inspect and Replace Suspension Components

• Tools Required: Socket set, torque wrench, jack stands, pry bar, and impact wrench if necessary.
• Remove the wheel corresponding to the side where the noise is originating.
• Inspect the struts and shocks for leaks or damage; replace if necessary:
  1. Remove the top mounting bolts of the shock/strut assembly.
  2. Unbolt the lower strut mount from the control arm.
  3. Remove the strut assembly from the vehicle.
  4. Install the new strut/shock by reversing the removal process, ensuring all bolts are torqued to the manufacturer's specifications.

3. Check and Tighten Loose Components

• Inspect and tighten any loose metal components in the suspension and undercarriage:
  1. Check all bolts and nuts on the suspension arms and sway bar links.
  2. Use a torque wrench to ensure they are tightened to the specified values.
• If heat shields or exhaust components are loose, re-secure them with appropriate fasteners.

4. Reassemble and Test

• Reinstall the wheel and lower the vehicle to the ground.
• Reconnect the battery if it was disconnected.
• Perform a test drive over various surfaces to ensure the noise has been resolved.
