Door bracket needs repair

[Huskymaniac]

Guys, my Tribeca still has an issue with the reinforcement bracket that supports the outer door panel. This is not the heavy duty crash bar. This is a simple bracket that runs diagonally across the door, is welded to the door frame on both ends and has an RTV type substance between it and the metal door panel. The weld on one end broke so this thing is sitting in their vibrating. I tried to jam a rubber o-ring in there and it held for a couple of weeks but eventually worked its way out.

Any suggestions on how to get this repaired permanently? The dealer suggested a body shop can weld it but I am skeptical. The weld point is deep into the door near the door latch mechanism. I could barely get my hand in there. I was thinking of slipping another thicker piece of rubber in there with some rubber adhesive to hold it in place. However, if that doesn't hold, I will have probably made it impossible to weld after.
