Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Use wheel chocks to secure the vehicle.

2. Raise the Vehicle

Use a hydraulic jack to lift the vehicle and secure it with jack stands.
Remove the front or rear wheels as needed to access suspension components.

3. Inspect and Replace Components

Strut/Shock Absorber Replacement:
- Remove the strut mounting bolts using a socket set.
- Detach the strut from the steering knuckle.
- Replace the strut assembly with a new unit, ensuring proper alignment with mounting points.
- Torque the bolts to manufacturer specifications (usually around 50-70 ft-lbs).
Bushing Replacement:
- Use a bushing removal tool to extract worn bushings from control arms.
- Press in new bushings, ensuring they are seated fully.
Ball Joint Replacement:
- Remove the cotter pin from the ball joint.
- Use a ball joint separator to detach the ball joint from the control arm.
- Install the new ball joint and secure it with a new cotter pin.

4. Reassemble and Lower Vehicle

Reattach the wheels and tighten lug nuts to the specified torque (usually around 80-100 ft-lbs).
Lower the vehicle back to the ground using the jack.

5. Final Checks

Perform a test drive to verify that the noise has been resolved.
Inspect for any new noises or issues.
