Check the suspension...
After moving my Westinghouse SpaceMates years ago, from the house, to the apartment above the garage...moving them up stairs etc...the rubber snubbers that are part of the lower suspension (think long metal tongs, with rubber covered suction cups on the ends), were no longer centered over the metal flanges that they normally sit over/on.
When I fired up a load of towels for the maiden run the machine made that horrible noise during spin. You must raise up the tub, while alternately repositioning the Tongs over the metal flanges. You will need someone to help LIFT the tub becasue it's DAMN heavy, with all those concrete balancing blocks it uses.
Also, The upper tub springs, may have bent the mounting tabs they hook to the frame of the machine quite severely. You may need to bend back these tang/mounting tabs as someone lifts that DAMN heavy tub from beneath. You may even need two people.
They upper springs on those old Westinghouse Laundromats from that era remind me of a childs rocking horse.
(Think four heavy duty springs. mounted on all four corners all angled inwards towards the tub assembly pulling hte entire mechanism upwards.. These springs can get sagged out, and there (is) to my knowledge no adjustment for them.
Of course my machine was NOT a dual tumble, and had one motor for wash/spin and drain. Yours may be different, but I wouldn't imagine so.
Once you tear into it, you'll kinda see what I mean.
And I never found a way to adjust the outer door to create a stronger seal. These machines were just NOTORIOUS water leakers, especially when overloaded the slightest bit.
And as far as I'm aware, parts are harder to find and I'm sure NLA from ElectroFrigiWestylux. So hopefully as it was noted, you be able to make one good machine out of two.
