Finally got under to take a look at adjusting the ample steering wheel play I have. I found the locking bolt/nut part and can not get it to budge. Before I oil it up and work on it more I have a question on the adjusting bolt itself. I noticed its already backed out about a quarter inch, maybe a half inch. Is that normal or is it possible its already been adjusted to the extreme? Since my box has a slight leak, I am considering replacing anyway. But in the mean while I would like to get some slack out of the system.

On a side note, what a pain this is to get to!!
