I've never had to replace one ..
on hundreds of vanagons even ..
There is some wear on the teeth of the wheel and on the pawl that
notches into it, sure,

Never had a problem though.  Not a weak are at all let's say.

I do make sure the star wheel turns freely on the threads it rides on
..I make super sure of that.
and I make sure the threaded 'bolt' turns very freely inside the round
thing ..
never saw one rusty there or stuck in any way.

'almost never a problem' is your basic answer, at least in my world.
