Hello. My tailgate has detached it's driven strut from upper connection. Not only did the ball joint separate but the the ball mount has detached from the door itself. It looks like a machine press fit into a lug on the tailgate itself. Any advise on how to fix this? How would one re-attach the ball to the tailgate? could it be welded? I notice piston now always wants to be extended even when the button is presssed to close the door. This is a real pain as its impossible to close the tailgate now as the piston always re-extends itself after a close button pressed. Help please.
