Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Safety: Ensure the vehicle is in "Park" mode and the engine is off before starting.

2. Inspect and Replace Worn Suspension Components

Tools Required: Socket set, torque wrench, jack and jack stands.
Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the wheel on the affected side to access the suspension components.
3. Inspect the struts or shocks for leaks or physical damage; replace if necessary.
  - Replacement: Remove the upper and lower mounting bolts, detach the strut, and install the new unit using the manufacturer’s torque specifications.
4. Check and replace worn or damaged bushings in control arms and sway bars.
  - Replacement: Use a bushing removal tool to take out old bushings and press in new ones, ensuring correct orientation.
5. Reinstall the wheel and lower the vehicle.

3. Tighten Loose Components

Tools Required: Torque wrench, socket set.
Sub-steps:
1. Re-check all mounting bolts and nuts on the suspension components for proper tightness.
2. Use a torque wrench to tighten components to manufacturer specifications to prevent rattling.

4. Test Ride

After completing repairs, take the vehicle for a test drive over bumps to ensure the noise has been resolved.
