well first off, I used Heavy duty High Heat Super Nice Grease when i rebuild wheels so i dont think that is the problem.
Second, running a 30mph axle at 52 is a dumb idea! but it seems others are doing it with no problem and its never happened on any other wheels of mine, Just the Snowflakes.
ummm.... Im absolutely positive they are and were packed and adjusted correctly.
The Last time this happened there did not seem to be and scoring.
Oh and breaking an axle at 52mph was not even scarry at all. To be honest it felt like running out of gas, it just started to slow WAY down and surging like it was going to die. I did not realize it had broke until i pulled over and investigated the problem.
So yeah, it sounds like no one else has had this problem.
That sucks, well good for you, bad for me. Guess its time to convert to sealed bearing in back with a 12 or 13mm Axel.
The Front was an easy conversion, but the back is going to require more work, but im tired of having to tear the wheels apart and being stranded on the side of the road.
Thanks for the feedback!
