These bolts are indeed VERY tight. I needed to use an impact gun to get mine off and I suggest that you do the same or you might break the steering lock if you are pushing against it with a hand tool.

Also, the manual indicates this is a "one time" use bolt and should be replaced any time it is removed...I re-used mine but thought you might like to know that fact.
