How do I get these things off? I need to replace them. Any help would be greatly appreciated! Thanks

The side rails snap on. Look under them and you can see the plastic tabs that hold them on. Starting at one end squeeze these tabs one at a time while you lift the rail and it should come off easily.

The tailgate rail is held on by the same screws that hold the tailgate access panel on. Remove the screws and the panel then pop the rail off.

Hope this helps.
