you have to remove the whole drum.if it is a one piece drum you can't just replace the bearings you have to purchase a whole new drum complete.if drum splits you need 2 bearings,1 bearing seal and 1 tub seal for a basic repair.the drum shaft might be damaged and need replacing but you will not know this until you have stripped it down and assessed its condition.BIG DIY JOB.lots of engineers dont do these because of hastle and cost involved!
