Stronghold chuck

I'm having issues with a stronghold chuck, on 1 side the chuck key turns as it should with 1 finger. The other side is almost impossible to turn using a lot of force, it's like it's running on cobblestone. This happens even when the jaws are out and the slides are removed. To my knowledge it has never been dropped and is basically new as I bought it last July. I have other strongholds that work as they should.

Any suggestions? The number on the chuck is something like 091472, does that mean it was manufactured in 72?

Thanks
 
Thanks for the replies, I took it all apart this afternoon before posting, took a wire brush to everything and no improvement. I will put a thin coat of lubricant on it tomorrow and try that
 
Look carefully at the offending part and compare to the other, something has changed, worn or broken, it could be an issue in the hardening but something has moved worn or broken

If it’s still under warranty, I’d call Oneway and see what they say. I’ve been using their chucks for decades without ever hearing of this problem - sounds like it may not have been machined correctly. They’d want to know, it’s a good, family run business. Actually I’d call them whether the warranty was intact or not.

Their equipment is nicely designed and well machined. I can’t recall ever hearing of one of their chucks not performing as expected.
 
I have several of their chucks and have been pleased with them all except the last 1 I bought last July. As for the offending part, I'm not sure exactly the part would be. As I mentioned the chuck works fine from one side but put the key in the opposite side and it's almost impossible to turn. This is even with the jaws removed and the 4 slides removed as well
