The skate plate (diagram #14) may be out of alignment. I have found this when a Whirlpool built Direct Drive washer has been laid on it's side or after an out of balance load. Try opening the lid and grabbing the inside of the tub (be careful not to grab the tub ring #8 in diagram ~ I have broken one before) Lift the tub up and move around a little to re-align.
You can check the suspension pads. (#13 & 15) Sometimes these can disappear for no apparent reason. If they are in place, you may want to sand them a little with some fine sandpaper. They could be causing friction and not moving smoothly. Be sure to do both the upper and lower pads.
The other thing is that the brakes may be grabbing too hard at the end of spinning. This creates a jerking like motion. I have added just a little axle grease on the brake housing just between the brake spring. Not too much, just a little dab will do ya. Be sure to not get any near the clutch... you don't want it slipping....
By the way - IMO this is a great machine - Best built EVER!!
But opinions are like buttholes, everybody's got one....
