Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface and set the parking brake.
Use wheel chocks to prevent the vehicle from rolling.

2. Inspect and Replace CV Joints

Tools Required: Jack, jack stands, socket set, torque wrench.
Raise the front of the vehicle and secure it on jack stands.
Remove the front wheels using a socket set.
Inspect the CV joint boots for tears. If damaged, proceed to replace the CV joint.
Sub-steps:
- Remove the axle nut using a socket.
- Disconnect the lower control arm from the steering knuckle to free the CV joint.
- Slide the CV axle out from the transmission.
- Install the new CV joint by reversing the removal steps, ensuring to torque the axle nut to manufacturer specifications (usually around 150 Nm).

3. Check and Replace Suspension Components

Tools Required: Socket set, pry bar, torque wrench.
Inspect control arms, bushings, and struts for signs of wear.
Sub-steps:
- If any components are found to be damaged, remove them by loosening and removing bolts with a socket set.
- Replace with new parts and reinstall, ensuring all bolts are torqued to the specified values.
- Reassemble the suspension and replace any strut mounts if needed.

4. Test Drive and Final Inspection

Lower the vehicle and remove wheel chocks.
Test drive the vehicle to ensure the clunking noise has been resolved.
Recheck all connections for tightness and inspect for any new noises.
