Noisey brushless motor

[qatmix]

Ello all

My speed passion motor has started to become really loud. It still runs but sounds like a tractor.

It doesnt seem to be the bearings as i have taken it to bits and they seem fine.

Looking at it closley it seems that the shaft isnt keeping straight when rotating. The motor has just been in my tc so i cant see why / how the main rotor could have warped

Any tips or advice is appreciated

Cheers
