If you look at the pictures you can see the black camber plates have a differant bearing then the two other units and this is the bearing you want, it looks like a 10-COM-T bearing, the T stands for teflen. You can also get this bearing without the T but then its rubbing metal on metal, and it will wear away causing a clucking sound. The non T bearings have oils in it to try to prevent it from wearing away but a poorly built unit will leak out the oil and wear out quickly. If you get a T bearing you sould be about to use it ten times longer then the non T units. The 10 refers to a inner diameter hole. Hope I you understand why the bearing is the weakest link now.

 

Witch set are you using? Stage 1, 2 or 3? I'm considering stage 2 camber plates. I'm told that theses parts are not very good!

I don?t see another alternative. I would rather take the time to improve and existing product then developing my own. I would take more time then what these parts cost.

Did you isolate the cause of the noise?
