Thank you for your advice. Just for so everyone can chime in I failed to ad that, the tub plug for the counter balance is in place and it looks fine, the mechanism support looks brand new, the snubber looks fine, but I don't know what "fine" should really be. The tub never stops off center, and has a good resistance when I grab the JetCone and rock it back and forth. It takes a great deal of effort for me to push the tub up against the water container, but I can do it.
