      Yeah, there's some trouble getting that bearing back in stock. They're all on back order.

                  The bearings in mine exploded. Aero said they'll send out a new one but haven't received it yet. They seem to be good for oiling your driveline though even if your not using it with the flex saver and other parts etc, I think.
                  It actually ended up locking up my driveline... so if I didn't notice the busted bearing in time it would have easily caused an entire meltdown in that side.
                  I think it's good for some setups where water runout is a huge issue and/or lower rpm stuff, otherwise... im sure its just an extra thing to break and cause havoc.
                  I'm not the only one with these bearing issues-- I have talked to at least 1 other person that had the same thing happen and it was in the similar kind of a high RPM catamaran setup as mine.
                  The fact that these replacement bearings are no where else to be found is something to consider.
