I have two sets of locking hubs. I have never broken a hub, but I bought the second set in Moab for spares when I didn’t realize it was the front lock rite locker going bad. I have run all of the hubs, so they all have rock rash.
First set if Warn $40 for the pair. Warn set is SOLD.
Second set is Mile Marker, plus and extra outer cap that I found on the trail once. $40 for the pair.
I had no issues running the Mile Marker hubs. I put them on in Moab 2013 and had run them ever since. Prior to that I had been running the Warns since 2002.
I am located in Canton but will meet up a reasonable distance.
