Under counter pantry slide removal

I am trying to figure out how to remove the slide out under counter pantry style shelves on a 1994 34' Classic. Have looked at the slide mechanism and I can see no way to unlock and pull the unit out. The reason I want to do this is because it looks like the end of the slide inside the cabinet has come loose and the drawer is not fitting correctly. The bottom is out about 1/2" compared to the one beside it. Also, there are a few items that have come off the shelves and need to be retieved. Thanks
