I have about 15K or so on the Calmini steering kit, no problems...I grease it every 2-3K or so with Mobil1 Grease.

The synthetic grease has worked well for me on other parts/applications...so I hope it does the trick here too.

I also have, as backup, a set of experimental higher quality bushings from xterraxcursions....so if the Cal's fail, I have a new set to swap in w/o downtime.

Bushings wear out, they're bushings....its all a matter of when.
