Steiner 430 MAX Float Detent

[Industrial Toys]

Any idea how long these detents are good for? My 430 has 550 hrs and the detent just failed it seemed one day to the next. You feel it's there, but it won't hold. The assembly appears still bolted up tight.

Aside from robbing the Aux which I don't want to do, is there any other fix other then buying a kit?

Thanks
