I have Park Shop cone wrenches and was going to adjust my front XT Hubs but....they won't fit between the dust cap and the outer nut. Is it just me?? Are there thinner cone wrenches out there that will work?

If you're talking about the rubber dust caps, just remove them, no big deal. Then put them back on when you're done-

Take a look at the picture to see what I mean.

Maybe use a file to take a little material off the wrench, it looks like it wouldn't take much to make it fit-
