First, order all of your parts from appliancepartspros.com. I ordered the rear main seal. Also ordered new seals and drain pump because I knew the case was gonna be fully opened. Rear main seal is behind the stainless tub so the whole machine has to be opened up and the tub has to be removed. Then slit the plastic tub and pull stainless tub out. Pry out rear main seal and replace. Then assemble unit back. There are some good videos out there. Took me about an hour from start to finish.
