I'm a new erbe owner (6 days). I'm trying to figure things out one small step at a time. I was wondering if someone could offer some insight on the assembly of the axle carriers, especially the pivot ball caps. I see how the special tool included with the erbe is used on this part, but I'm not sure what's happening when I turn it. Does it tighten and loosen the axle carrier's grip on the pivot ball? If it's loosened all the way, can the pivot ball be separated from the axle carrier? Any info would be helpful. Thanks!
