Yeah maybe I got a bad batch that only lasted 6 years. Or conversely maybe I got a good batch that managed to last 6 years.
Either way I have sourced a set of OEM hub/bearing assemblies
so I keep hearing! Even from life long mechanics. Apparently this failure is unheard of…
Got it back home and got started pulling the hub off and diagnose the issue. Axle was stuck after removing the 36mm nut so i used a 3 jaw puller to try and push it out and...

spend the next few hours trying to remove the axle from the remaining hub as it was very much jammed in there when the spindle sheared off.
resulting damage as below

Looks like the was already a stress fracturing in the spindle as can be seen with the darker cracked section
My working theory is maybe when the pinion gear exploded last year the shock put through the hub was the initial crack. Then a few events later it finally let go. Just lucky it happened where it did and not 190km/h on the next sweeper or into the hairpin
The bearing/hub assembly went in in 2019 and were non-genuine "ZSS" assemblies
and no nails were harmed in the process. #BreakHubsNotNails
