Travis,

Sorry I can't help, but I am keenly interested in others' input on this, as I am very close to the end of my pushrod, and I have to be careful when tightening the jam nut in such a way, to prevent the pushrod from walking out, since there are only a couple of threads left.

So, in essence, I have the same problem, only I have just enough left on the pushrod to actually function, and I have always wondered if this was common. I have already had it walk out, once. It took about 500 miles, but I certainly don't want to have to deal with that again.

Hope you get some useful input (not just for my sake).

-Gary
