Fixed it! Yay. New issues... boo.
So I replaced the clutch and the drive block. My knuckles are bloody and swollen now, but the spin works.
Here's the problem. Now when I run it, the machine shakes wildly on agitation and spin, AND i think it may be leaking a little.
So I think probably the tub seal on the leak, however, not sure about the shaking wildly. I think I put everything back together well. Could I have missed something?
Thanks very much!
