shocks look ok
I checked the shocks, they look ok. While sitting in front of the washer, I turned it on the spin cycle. Looking through the glass door, I could see the back center of the tub wobble off center a little. When it went to high speed spin, then it wabbled more and began the knocking. I'm guessing the tub is centered on a bearing in the rear, and something's gone wrong in the rear center??? The washer is too heavy for me to slide or move at all. Guess I'll have to contact a repariman when I start back to work in the future. If you have any other ideas about this, please let me know. Thanks a lot for helping me. Pam M.
