Noisy Hoover AAA140-01 washing machine drum bearing?

Hi
I have a problem with my Hoover AAA140-01 washing machine in that the main drum bearing is making a lot of noise on spin.
There is no movement in the bearing but on inspection there is a line of grease leaking from the bearing. Could anyone tell me if this is a complete strip down to replace or whether there is an easier way.
Many thanks
Alan
