This is literally a 10 min job. 4 screws and one nut. What happens with ours was that the permanent magnets had diminished over time and were no longer effective. The spline shaft was fine in the old part. Repeat it was the magnets that were keeping the drum from moving. This part acts as a rotor, like on an electric motor. Basically, the drum is the electric motor. This information is for those who don’t know a thing about electronics. I hope this info helps someone.
