Did you check to see if the hinges were wore out? Lift the doors up/down. If theres play replace the pins/bushings.

Thanx guys! Everything that you all have suggested I have not tried yet and makes a lot of sense. I have a set of full frame connectors that have not been installed yet, the weather stripping is old and the doors do move up and down when I lift on them. The frame connectors were my first thought along with a roll cage to stop some of the uni frame movement. Thanks again!
