Replace the suspension pads, part 285744, and the clutch. Add a thin coat of grease on the spin tube. Clean the floor of any oil, soap, or softener residue. Then, clean and sand the bottoms of the 4 feet and level the machine. This should make the machine behave in the spin cycle, and get rid of any "skating" problems..
I also tighten the fit of the cabinet to the base. With the case off, I put something about 2 inches thick under the side rails of the base midway between the front and rear legs. Then I push down on the base to bend the rails up in the middle. Then I use my foot to bend the front rail down about 1/2 inch. Now, when you put the cabinet back on, you will have positive pressure between the base and cabinet. This really cuts down on the noise during the spin cycle, and the customer sees a real difference in the "before and after" repair performance.
