Rer3, just remove the two bolts from under the bedrail.....ya dont want to take off the two on top of the bedrail!!!!! They are kinda tricky to put back on......of course you dont need to take them off to remove the wing at all, just wanted to share the tip. After you remove the lower bolts you just kinda nudge the wing to the rear, then lift up and off....there should be some directions with the tool they give you.
