Kenmore 20722990 washer works fine until it finishes the spin cycle. Then as it slows it vibrates as if it is unbalanced but it's not. I have the cabinet off, the agitator and tub removed. What's next?

Re: As it spins down it vibrates until it stops
Check the Vibration damper rods to be sure that... 1. They are there and mount is solid. 2. If they are broken in 1/2. 3. The plastic knuckle mounts are not missing/broken. 4. There is oil in the shock absorber/spring section of the rods.
Also - there are suspension springs on the bottom of the tub that could be broken and/or missing.
Replace/repair as necessary.

Make sure the legs on all four corners are down tight and even level the machine with this 4 pads. If the machine is level it will vibrate less, and then not all machines are completely quiet when working, especially on spin cycle..
With the lid open, set the cycle to spin and press the lid switch button with a pen. Wait until the drum gets to full speed and release the lid switch. If the drum makes a knocking/ thumping noise and doesn't stop spinning within 2-3 seconds, the basket drive block is worn and needs to be replaced. (The basket drive block is located on the gearcase drive shaft, under the tub and agitator) If this has been happening for a long time you may need to replace the brake and drive tube assembly as well.
Basket drive block part number is 389140
If that's not it, let me know and I will try to help you further. Good luck!
Timer is defective. Your unit has a netural drain. When finished agitating, the shuts down and then starts up reversing to drain and spin. On the initial reverse start, the water drains without the transmission spinning. After a timed period 3-4 minutes, the timer is supposed to pause, stopping the motor for a few seconds. When the motor stops again, the transmission shift to the spin cycle and when the timer resumes power tothe motor it should spin. You are doing the same thing when you lift the lid...stopping the timer and then the tranny shifts and when you set the lid down, the washer spins. Replace the timer.......
