kaeesae, the noise is now back so thats that sorted. i cleaned out the grease and used some heavy chain lube. It appears to be the drive side seal that has failed and let in the weather. it was pretty baggy on there.
The rotation resistance was just more than hat i expected to be honest, since it is very smooth i guess thats how it is supposed to be. The wheel spins freely when the bike is upside down just not as long as me older deore hubs. I guess that is inherent to sealed bearings.
Rorschach.. Dont rub sweat of your face when running after preparing ingredients ready for a curry, ginger stings more!! trust me.
