Can i replace the bearings on my Indesit w1235 myself?

Does anyone know if i can change the bearings on my machine myself? Its been making a lot of noise for a while now even though its been working perfectly well!! I think its about time to do something about it before something else goes. If anyone knows how to go about this and how to get to the bearings i would really appreciate any info.
Many thanks
