Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Raise the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle, depending on where the noise is coming from.
Secure the vehicle with jack stands for safety.

3. Inspect and Replace Worn Components

Shocks/Struts:
- Remove the bolts securing the shock or strut assembly.
- Replace with new shocks or struts if they show signs of leakage or damage.
- Torque bolts to manufacturer specifications.
Control Arm Bushings:
- Remove the control arm by unbolting it from the frame and steering knuckle.
- Replace worn bushings using a bushing press tool.
- Reinstall the control arm and torque to specifications.
Ball Joints:
- If ball joints are worn, remove the wheel and brake assembly.
- Unbolt the ball joint from the control arm and steering knuckle.
- Replace with a new ball joint and reassemble, ensuring proper torque is applied.

4. Reassemble and Lower Vehicle

Reinstall any components that were removed during the inspection process.
Ensure all fasteners are tightened to specifications.
Carefully lower the vehicle back to the ground.
