Knocking Whrilpool Duet
The "cleats" inside the wash tub are actually called "fins". If they are loose try tightening them to see if the sound goes away. You should be able to tighten them from inside the wash tub. Some models have mounting screws that are accessible from inside the wash tub. However, if your machine is knocking like you say it is, it could be sign that one or more of the mounting shocks under the wash tub could be bad, the rear tub bearing could be going bad, or the drive pulley could be cracked or warped.
Remove the lower kick plate and watch the shocks during the spin cycle. The shocks should vibrate some, but should not be excessive to the point that it causes an unbalanced spin.
To check the drive pulley, remove the 3 screws from the washer top in the rear of the machine. The top should slide back some and then lift off. Watch the drive pulley behind the wash tub during the spin to make sure the rotation is smooth and even. Sometimes one of the arms on the pulley can crack or become bent and cause the pulley to wobble. More than likely, though, the drive belt would slip off. I have also seen where the hole in the center of the drive pulley starts to "round out". The hole is not perfectly round and has to flat sides. Sometimes over time the drive shaft will start to slip around the flat sides, causing the pulley to rattle during the spin cycle.
If the rear tub bearing is starting to go, the washer will be very noisy during the spin cycle, and you may start to notice some stains on your clothes if the bearing seal has been breached. You can reach inside the wash tub with the unit turned off. With one hand, push up on the wash tub and release. If you can feel the tub moving up and down (even the slightest) this could be a sign that the bearing is worn out. Now this should be a noticeable metal on metal type feel. Not the normal motion of the wash tub moving up and down from the motion of the shocks. The tub bearing is not a cheap (or easy) fix. The entire back section of the rear outer tub shell has to be replaced, because the bearing is molded into the plastic. Check all the easy things first. Let me know if this helps.
