Two yr old washer won't spin. Other phases of cycle run ok ie fill agitate drain although lately have noticed sound of residual water in the tub (not visible in the basket) as the basket comes to a stop. Sounds like an object plowing through water. So water not draing completely at the end of the spin cycle. Clothes would come out still wet requiring a second spin. It is possible to rotate the basket manually although it takes some effort.

Basket will not spin when empty. Could the clutch still be the problem or is it more likely that the drive coupler or basket drive block is the culprit. Is the fact that tub is not draining completely related to the spin problem or is it a separate issue?

Removed case to expose motor and coupler which looks like new. Plastic couplers and rubber ring intact; no rubber bits on the floor to indicate wear. I poked at the clutch plate with a screwdriver and it does not seem lose or off center although there was a small amount of black dust on top of the transmission case directly below the clutch.
