When removing and installing a 2015-2019 Transit front subframe, the cage nuts located in the body of the vehicle may become damaged. If the nut spins in its cage when removing or installing the attachment bolts, the nut can be held with a socket through an access hole in the vehicles frame member. It may be necessary to bend the tabs of the cage up and away from the nut to allow socket placement. The cage nut has been released as a service part (CK4Z-61105A38-A) and can be replaced if damaged. The replacement nut can be removed from its cage and installed in the vehicle's original cage. It is not required to replace the cage as it is welded to the interior of the vehicles frame member.
