The white ones squeak. Just call Calmini and they will send you new ones for free.

I have the bronze bushing problem too. The first original bushing lasted for about 6 months, then it got sloppy as hell with knocking noises on small street and offroad bumps. Calmini sent me a new bushing that suppossed to be "better". Now this one is lasting about 6 months too. I'm back to the sloppy-knocking sounds again. I haven't called Calmini again yet about the problem.

Again, the Calmini steering is something that is really tough and needed for a lift, but this bronze bushing crap sucks.
