The sites suggested it probably was the centering springs and/or and support rods. Showed a video on how to replace those items so I order both. So far it seems to be just the centering springs was worn out. Replaced both centering springs, the easiest thing first, and it is working fine. Will keep the rods just in case I need them. The service was great. Items were here the day they said they would be and they are an exact fit.
