Indesit WI101, rattling drum and leaking!! Help!!?

The drum makes a nasty clunking sound when on high spin (otherwise it's fine), doesn't appear to be the bearings and motor seems fine.

There is also a leak, although I haven't identified the source as yet other than it isn't from water inlet or waste pipe, appears to be within the drum seal.. possibly!!

Any help would be appreciated.

Thanks
