Solution

1. Preparation

• Gather tools and parts required for inspection and repair.
• Park the vehicle on a level surface and engage the parking brake.
• Disconnect the 12V battery to ensure safety during repairs.

2. Inspect Rear Suspension

• Sub-steps:
  • Use a socket set to remove the rear wheel on the affected side.
  • Visually inspect the rear shock absorbers, control arms, and bushings for wear or damage.
  • Tighten any loose bolts or nuts to manufacturer specifications (consult the service manual for torque values).

3. Check Trunk and Interior

• Sub-steps:
  • Remove any items from the trunk and rear storage areas.
  • Check for loose interior trim or components; secure or replace as necessary.
  • If applicable, remove and inspect rear seat mounting points for tightness.

4. Test Drive and Listen

• Sub-steps:
  • Reconnect the 12V battery.
  • Conduct a test drive over various surfaces to ensure the noise has been resolved.
  • If noise persists, further investigation may be needed into the rear differential or axle components.
