Axle nut different

Hi Adam,

Did the axle nut that did not have the cotter pin have some other way of preventing it from loosing? Like a lock washer or anything? If not, sounds like the wrong axle nut. I would recommend calling the supplier of the part and telling them what it is doing so they can tell you if that was as design. If not, I would reuse your old nut and use the castle lock cap and a cotter pin. Long story short, you don't want to risk that loosening.

Let me know if you have questions or what the supplier says. Thanks
