Wihle changing my oil, waiting for it all to drain out (I'm veyr anal and let it sit for a long while), I decided to take a look at my loose steering. It looks like most of the looseness I"m getting is in the box. I decided to try and adjust the box to make it tighter. However, while I know that the adjusting screw (Allen-head, right?) is left-hand-thread, what thread's the locknut that goes around the adjusting screw? It doesn't want to turn either way, and I figure I'd better find out which way it turns before putting serious pressure on it.

Thanks! And I know that the adjusting screw itself should only be turned until you begin to feel resistance...
