No, this is just pivot wear.
You'll find its worse in over-tight pivots. the hard ano wears off first, then the wear debris fills the helix and fresh grease doesn't penetrate, and you get accelerated wear at the bush/pivot interface.
best I've had from a set of turner bushes is about three, maybe three and a half years.
If theres a step in the shaft or play when its in the bush, its best you replace it, but if you're in a pinch, its not suddenly going to fail on you.
You can hone the bushes to fit if they're over tight, and its a relatively frequent occurrence that the bolts are over torqued from new which mushrooms the end of the shaft and closes down already tight tolerances.
Its a good system when its been put together with care, but its easy to see from a google search or the mtbr forum that this happens more that Turner would like to admit.
Despite that, I'm still running Turners 8 years after my first one.
