Yeah, they turn just like any other bolt. Just spray a lot of pb blaster on it and keep going at it. If you have access to an impact wrench, they seem to work well in that situation. I know there is very little room, but when I took mine off I had to use a piece of pipe over the end of the wratchet. It would only turn one or two clicks every time, but at least it worked. Just keep giving it hell.
