I have a 1997 Tahoe and when on the highway at 55+ mph my windshield starts to rattle, like it's going to come out of the frame.

No leaks, and I have gone a few hundred miles like this. Does anyone know if it poses a problems other than the annoying sound? Anyone else?

Brady, do you still have this problem? Is it the gasket gone out? Do you have any water leaks inside of the windshield?
