where do I start?

My washing machine is starting to make quite a bit of noise which in the past indicates that the bearings need changing. But on looking into the innards of the machine, I can't make head nor tail of how to take the bearings out to replace them as the innards are totally different from my previous Indesit washing machines. Anyone else had that problem? I can't even make out which part I need! My washing machine is an Indesit WI101 front loader. I have always had Indesit machines but this is the first one that has flummoxed me.
