First I tried to fix it by stuffing foam on all sides of the drum. That made it better but the machine moved all over the place in spin cycle. Finally, I bit the bullet and purchased the 4 damper assy rods. Install took 15 minutes and now the washer is like new. Spins fast and stays in one spot. No more annoying DC errors. I only wasted $20 on the foam so It cost $100 total to not have to buy a new machine. The video showed exactly what to do. It was simple. I'm very pleased.
