Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues while working.

2. Inspect and Remove Components

Tools Required: Socket set, wrench set, jack stands
Sub-steps:
1. Use a jack to lift the vehicle and secure it on jack stands.
2. Remove the wheel on the side with the noise to gain access to the suspension components.
3. Inspect the struts and shocks for leaks or damage. If damaged, remove the strut or shock by unbolting it from the upper and lower mounts.

3. Replace Worn Parts

Tools Required: Torque wrench, new struts/shocks, suspension bushings (if needed)
Sub-steps:
1. Replace any worn struts or shocks with new OEM or quality aftermarket parts.
2. If bushings are worn, replace them as well, following the manufacturer's specifications for torque values during installation.

4. Reassemble and Lower Vehicle

Tools Required: Torque wrench, jack
Sub-steps:
1. Reattach the wheel and secure it with lug nuts, torquing to manufacturer specifications.
2. Lower the vehicle back to the ground and ensure everything is properly tightened.
