2. Raise the Vehicle

Use a 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 Components

Shock Absorbers/Struts:
- Remove the wheel to access the strut assembly.
- Disconnect the strut from the lower control arm and the upper mount.
- Replace with new strut if leaking or damaged.
- Reinstall the strut and torque the bolts to manufacturer specifications.
Sway Bar Links:
- Remove the sway bar link at both ends.
- Inspect for wear or damage, and replace if necessary.
- Reinstall and torque to specifications.
Ball Joints and Tie Rods:
- Disconnect the ball joint from the control arm using a ball joint separator.
- Replace with new ball joint; ensure proper alignment during installation.
- For tie rods, unscrew the old tie rod end and replace with a new one, then re-align.

4. Reassemble and Lower the Vehicle

Reinstall the wheel and lower the vehicle back to the ground.
Tighten the lug nuts to the specified torque.

5. Test Drive

Perform a test drive to ensure the knocking noise is resolved.
Listen for any remaining or new noises.
