Just going on my experience... And to quote Andrew Tonkery: "Kings have lemons..I've had 3-4-5? king hubs, one of them was just like this- it never worked, even after sending it to king for an overhaul...it was an ISO w/trials internals, hd axle, steel drivesheell, funbolts...skipped all the time, was a huge piece of trash. Every other one has been fine, current one is a classic w/aluminum driveshell- normal axel (foley), just run of the mill cross country...its over 5 years old, I've owned it the whole time and I've neven even touched it- never opened it up to lube it or anything. It has never skipped or come loose since it came out of the box" Didn't matter what I did to my hub, it skipped continuously.
