'Green' bearings... Any known issues?

I have the said "green bearings" lots of road courses, miles and miles of twisty mountain roads, 30 k miles on, so no issues here , but I too have heard they fail,so hope mine hang in there,knock on wood

Has it had a back brace put on etc after the housing ends were put on?

It was built by S&W originally and they fitted the ends. I had to get the tube lengths altered so I sent it to Hausers for that. Nothing's been done to it since then.
I reckon I can be pretty confident Hausers would make it straight

Had green bearings for years and given all types of abuse

Do you also run wheel spaces I've known these to throw out wheel bearings due to the extra stress - loads they cause .
Never a dull moment with these motors

No spacers Rich but wheels like dustbins might not be helping

I wasn't paying attention when you said at the start it was a 9"

I'm not familiar with that and (as Dave said) some axles do originally use roller or ball bearings with no issue if they have properly located/retained axles that don't rely on the bearings to take the side loads.

So I don't know the 9" standard setup, but would assume that if they were originally tapered, and have nothing else to take the side load, then the same would apply as to 8 3/4 regarding side loading. Though even if they were, they may be other differences, for example if they had larger/stronger bearings that the 8 3/4.

So hard to know how much of what is relevant to 8 3/4 applies to 9". Obviously the basic physics doesn't change, but given that for the 8 3/4 it's not clear why some specifaclly fail and some specifically don't, I've no idea how much can be assume for th 9". The user base as always is the best reference, and the 9" user base is HUGE!
