Just for the benefit of newer owners who might find this thread (or who are reading it now), the plugs are removed and retightened with a standard 1/2" drive ratchet. This is obvious if you get under the truck and look at the plugs, but it seems almost
too obvious the first time you look. It's an easy job, just a little stinky as RageRover pointed out.
OK, OK...a lot stinky. Don't spill it anywhere, trust me
