How do I change the drum bearings on my Indesit W123UK S/N 010167254?

I believe the drum bearings and seal have failed on my W123UK (play when the inner drum lip is lifted, rumbling noise when the pulley/drum is rotated by hand, and brown oily witness marks on pulley/back of outer drum/inside of cabinet).

Do I need to remove the whole steel drum assembly (inner & outer) from the cabinet, before removing the Pulley (part number C0D174000703) & Spider (Part 174000696.04)?

Or can they be removed with the drum assembly in place? If this is possible how do you support the inner drum to prevent damage?
