how do I remove my spare tire
 

ok on a 2000 sd what tool do you use to remove the spare tire from under the bed looks like a torx or something like that any one know?????:-X19

The 'key' for it should be in the glovebox. If not, don't know what to tell ya.

Here you go. (see attached)

If your truck has a lock in the winch, then you will need the key.
If you don't have the key then a 9/16" socket on some extensions will work.
