Machine will have to be stripped down, bowls removed & gearbox taken out. Then the bearings (making the noisy spin because they are rusty) can be replaced. Also replaced at the same time would be the outer tub seal (which has worn & water is leaking down on to the bearings & the floor) While the gearbox is out you will need to replace the top & bottom seal on the gearbox. You may also find the gearbox has water in the oil so that will also have to be drained & refilled with clean oil. Big job.
