I searched for an hour and a half last night and couldn't find a solution to my issue.
I did the hex upgrade using the AE steering block (ASC9880), B4.1 hex front axle (ASC7496), proline clamping hexes front and rear (PRO6076-00, PRO6077-00). I'm also using JConcepts Mono 2.2 front and rear wheels (JCI3347, JCI3348).
The issue is, when I mount the wheels and try to put the 8-32 nut on, it barely threads on. The threads of the axle do not engage into the nyloc portion of the nut. So they come off easy. Is there a thinner nut people are using? Did I get a wrong part? I double checked to make sure I had the thinner hexes up front and I do.
Anyone run into this?
