Got a Cardone rebuilt axle to put in...along with a bunch of other stuff...it didn't have a new nut and it looks like it has the old snap ring on it.
They didn't sandblast this one...looks like they tumbled it in stones or something...wore a lot of the threads off the wheel end...etc.
Also doesn't have the 2 different sheetmetal seal guards or whatever they are on either end...might try putting the old ones on.
