Joseph C Kinnelon , NJ July 21, 2020 Noisy knocking, some water on the floor The hub nut was impossible to remove with the spanner wrench, I had to cut it out by drilling into it and then chiseling the nut until it broke. When I finally got down to the hub bearing, it did not show any wear and it was also impossible to remove. The bearing housing appeared to be fused to the plastic tub. I felt I would do more damage in removing it and possibly damaging the tub which then would have to be replaced. There is no signs of water leaking it appears to be working fine at this point.
