The directions I got said to soak the spider shaft (what you call the
inner drum shaft) in oil where it contacts the inner race of the bearing
(you ARE using a new shaft, aren't you?). And I also assume you have a
new seal for the front?

I am using a new front seal, but was unaware of the required new shaft, the
one I have is slightly rusty (must say after 8 years very little) and seems
fine. Cant seem to find it on the Hotpoint spares site
(www.theservicecentre.co.uk/Service/fr_shop.html), whats its part number,
where could I get one ?

Now I'm worried ...
