Hub broken by rotafix?

I feel horrifically silly asking this.

I was just rotafixing the shit out of a new sprocket onto my On-One hub, and while I was pulling it clicked loudly, which I thought was just the chain settling down on top of itself under the pressure.
Then when I took it out of the frame I noticed the axel was grinding very strongly when the wheel is turned.
It feels like very, very rough bearings.
I'm wondering if it was like this before and I just didn't notice until I'd taken it out of frame.
Any idea what's happened? The hub is less than 6 months old. I can't see it being very easy to fuck up the axel/bearings from rotafixing.
Seriously not gunna be happy if I have to buy a new hub.

Sounds strange, can't tell without looking at it but it sounds like a bearing may have gone. Just bad luck I think. I have on one hubs and roat fix and have had no problems.

Remove the axle and check it's not bent (should not be) by rolling it on a flat surface and try and fee the bearings (they are cartridge) if the feel gone pop them out and but new bearings.

If all is well then at lest you've checked your bearings.

More likely that it was fucked before rotafixing.

At least it's a cheap hub.

He who buyeth shit, buyeth twice.

At least it's a cheap hub.

Exactly.

bullshit there is nothing wrong with on one hubs maybe it was already broken maybe it was not, all companies have failures, even phill wood hubs have failures.

Sounds like it was already running rough to me. Cant see any possible way to damage the bearings using rotorfix (unless you somehow managed to warp the whole hub shell = very unlikely) It is not uncommon to need to service a 6 month old hubs bearings.
