Removed the lower spray arm assembly thumb screw and lifted off the spray arm assembly. The lower seal had disintigrated - couldn't even find any pieces in the filter. After reassembly with the new seal and bearing I turned the spray arm by hand to ensure it was not binding. There was still was, what I would consider, some excessive wobble. I fashioned a shim washer out of some plastic from a Folgers coffee can lid and installed it on the thumbscrew threaded shaft and tightened it all down finger tight - it works very well and now, and no wobble.
I relaced the upper spray arm seal while I was doing the job (both the upper and lower seals are the same part #). I figured it would go out on me eventually, so I might as well replace it while I was doing the lower arm work. Kept the old upper arm seal as an emergency replacement.

Cleaned the filter screen of all debris (it is amazing what collects there over time). Cleaned the stainless tub with some spray Greased Lightning, ran the rinse cycle, and then put a few tablespoons of citric acid crystals in the soap dispenser and ran the dishwasher on NORMAL WASH with temperature boost.
Looks new inside; cleans the dishes, glasses and utensils well (no water spotting); and is nice and quite (like when it was new).
