With the lid up, grab hold of the agitator and move the tub back and forth. Shouldn't be too stiff or to easy. Did one not too long ago that was like a car with bad shocks. Not only was it too easy to move but kind of kept going after I let loose. The transmission was weeping a little oil and it was getting on the snubber ring and baseplate. A new ring, a lower tranny seal and a good cleaning solved the problem.
