Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to avoid any electrical issues during the repair.

2. Inspect and Replace Suspension Components

Lift the Vehicle
- Use a hydraulic jack to lift the front of the vehicle and support it with jack stands.
Remove Wheel
- Use a socket set to remove the lug nuts and take off the front wheels.
Inspect Suspension
- Check control arms, bushings, and struts for wear. Look for cracks, tears, or excessive play.
Replace Worn Components
- If damaged components are found, replace them with new parts. For example:
  - Control arms: Remove the bolts securing the control arms and replace with new ones.
  - Bushings: Use a bushing removal tool to replace worn bushings.
Reassemble
- Reinstall the wheel and torque the lug nuts to manufacturer specifications (typically 80-100 ft-lbs).
- Lower the vehicle back to the ground.

3. Inspect and Replace CV Joints

Check CV Joints
- With the vehicle still lifted, rotate the wheels by hand to listen for any abnormal sounds from the CV joints.
Remove and Replace CV Joint if Necessary
- If noise is detected, remove the axle nut and disconnect the CV joint from the hub. Replace with a new CV joint or axle as needed.

4. Test Drive

Once repairs are completed, reconnect the battery and take the vehicle for a test drive to ensure the knocking noise has been resolved.
