How do you fix an over extended CV joint?

To fix an overextended CV joint, first, assess the joint for any damage or wear. If the boot is torn or the joint is damaged, replace the CV joint, ensuring to use the correct type for your vehicle. Reinstall the joint, making sure it is properly seated and lubricated, then reattach the axle and secure all fasteners. Finally, check the suspension geometry and alignment to prevent future issues.
