i have a hotpoint wm 67 is it the same as any other hotpoint washers?

Can anyone help please. I have a hotpoint wm 67 washing machine which i a told is in need of new drum bearings. Is the bearing change a pretty standard procedure for all Hotpoints,as there are already several answers which i could use[ie, wm31 and 35].Or are the bearing changes different from model to model? any help would be greatly appreciated.
