during the rinse, spin cycle the tub shakes more than normal almost if a broken spring or worn spring or a loose belt (if it had one). I have checked the underside and all looks o.k.nothing broken or excessively loose, no wear marks from rubbing. I can move the bottom of the tub,motor, and pump back and forth and from the top the tub moves what seems to be "normal" but does "seem" to be easier to move the inside tub back and forth easier than usual. It doesn't shake like it is off balance but it is loud and it's obvious by the shaking of the machine. If you put light pressure on the top with your hands the shaking all but stops but it is more than it should be. Is there anything else other than the balance springs that could be replaced? or is it time to start shopping? We did replace the pump and the timer already so good money after bad doesn't seem worth it. thank you!
