2008 f350. I want to remove the drivers side door panel. Is there any hidden screws to take off or does the whole thing being held on with the snap type fasteners.

 

Not sure on the 08 interior, but guessing it's similar to earlier ones, if so, lift up and out the switch plate, and there should be a bolt under there at least, might be more, I'm sure I'm forgetting a few locations. I'll be taking mine out soon to put some speakers in. It's definitely not all push fasteners though.

There's a thread on here somewhere too on door panel removal/speaker upgrade/etc...

 

I don't know if your year is the same but this is how to do it. Door panel removal
