I commend everyone willing to take the steps to build the right tool. I had dropped off my hubs this weekend at High Point Imports to have them rebuilt. Scott called this afternoon, with the question did you notice that one of the axle stubs had been shortened? Appears that in the past someone messed it up in a rebuild attempt and just cut off the end to get the nut on. This left it too short for the nyloc portion of the nut to work. The other side does not appear to have been redone. Guess they gave up after the first try.
Scott was excellent, providing another core to keep me on schedule, until I can pull one off my rust bucket donor.
So the word is, don't try this at home unless you have the right tools.
