- axles 29 1/4, buttons in place, 489 case, any ideas ?
What sure grip do you have , the case don't matter unless you know for a fact that it has never been messed with .
489 would have come from the factory with a Cone type , no buttons , just a thrust block that can't fall out.
Clutch type has buttons and they can fall out when the axles are pulled, the roll pin is an assembly aid , after many thousands of corner turns it will eventually break , it's not a potential problem till an axle is pulled.
