Repacking wheel bearings I attempted what I thought was a relatively straight forward job, servicing the front hub of my commuter bike and the result was terrible, but I'm not sure exactly what I got wrong. 

Apologies if this is obvious, I did already try googling etc and so this is my last try before taking it to a shop. 

Basically I followed a couple of instruction videos, but despite following all the steps I can't get the wheel to spin as smoothly as it did before. Either it feels like it's grinding, very gritty or there is still play in the hub, depending on how much I tighten. 

I have tried again, this time adding more grease, but same result. 

I'm pretty sure the cup and bearings are still ok, not too worn. Any ideas? Am I missing something? 

I'm using a halfords multipurpose grease. 

Thanks!
