finally got around to making the rear wiper functional. it operated all along, it just wouldn't touch the glass - too much corrosion in the wiper pivot/spring mechanism/bushing.

so, i took the whole thing off, and sprayed it liberally w/WD40 while working the pivot up/down repeatedly (oh, and i removed the spring to make it easier to do this). eventually, it got loose. i then sprayed the bushing with a small amount of PB'laster and worked it in. reattached the spring, and and went back out to the 4runner, and put the wiper assembly back in place.

the moment of truth. put ignition switch to on, pressed the rear wiper button, and it worked, cleared some glass - and the washer works to boot. not perfect, but at least 75% of the wiper blade makes contact with the glass surface. much better than it waving in the air above the glass.
