Solution

1. Preparation

Gather tools and parts needed for suspension repair.
Park the vehicle on a flat surface and engage the parking brake.

2. Raise the Vehicle

Use a hydraulic jack to lift the vehicle and secure it with jack stands.
Ensure the vehicle is stable before proceeding with any work.

3. Remove Wheel

Use a socket set to remove the lug nuts and take off the wheel.
Store lug nuts in a safe place for reinstallation.

4. Inspect and Replace Components

Struts/Shocks:
- Disconnect any electrical wires connected to the strut assembly.
- Remove lower strut bolts and detach the strut from the vehicle.
- Replace with new struts or shocks, ensuring proper alignment.
Bushings:
- Remove any bolts securing the control arms or sway bar links.
- Replace worn bushings with new ones, ensuring correct positioning.
Ball Joints:
- If play is detected, remove the ball joint nut and press out the ball joint using a ball joint separator.
- Install new ball joint and secure it with the appropriate torque.

5. Reassemble Components

Reattach the strut or shock and secure all bolts to the manufacturer’s specified torque values.
Reinstall the wheel and tighten lug nuts in a star pattern.

6. Lower the Vehicle and Test Drive

Carefully lower the vehicle back to the ground.
Take the vehicle for a test drive to confirm that the noise has been resolved.
