I think the large cornering forces are what can push the outer front bearing inward in the 26r aluminum bronze alloy hubs. These are brand new TTR hubs with around 500 road miles on them. The problem only arose while driving the car hard in corners to test the ARB.
There was a thread years back that discussed this mode of failure experienced during racing.
Quoting Rohan from 9 years ago:
? I have always stayed with the cast iron hubs on my competition Elan rather than add lightness with alloy hubs. The bearing races loosen as it is under high temp conditions. In an alloy hub it would be even worse and it does not look like the makers have got the fit tolerances right for hot hubs.?
At least it?s telling me perhaps I am pulling substantial g-forces in my test drives. On a private road. Otherwise I am sure I would be gaining some unwanted attention.
I probably should redo the other front bearing (cement it) before it fails as well.
