Sir HC, the outside of the shaft is ok with no marks, I covered it with some electrical tape first so I wouldn’t scratch it. The only thing wrong with it is the threads at the end are really stiff to thread a bolt on hence needing to chase the threads.
Had the forks since Feb/March and I’ve had the lowers off a few times before with no problems, once when I first got them to make sure they had some in (I’ve had some fox in the past bone dry before now)and a couple of time since for a lower leg service.
I’ve never used threadlock on them but from memory they had some white stuff on them already which I assume is some kind of threadlock.
Just thinking maybe Im missing something from the bottom of the lowers which as allowed it to spin inside.
