Assuming these are the hubs you have-I had a problem with my hubs locking and unlocking. The retaining ring on mine was bent ,even flimsier than it should be and no good. I replaced the hubs with another set ,that had that retaining ring in good shape , and they're working fine now. Good luck finding just that retaining ring though. I would just get some more locking hubs aswell.
