Wipers went screwey!

On my 66 F100, the driver's side wiper was slapping a bit as it bottomed out, so I took the wiper arm off and put it back on a bit higher. Alter a while, it began slapping on the bottom again with a wider arc that carried it too far the other way as well. Seems kind of strange. What do you suppose caused that? The passenger side wiper seems to work okay. Also, if anyone could point me to any diagrams or pictures about this system, I would be grateful.

The wiper pivots wear out as does the bushings in the wiper transmission arms. Carpenter has both. Junk yard parts are usually worn out as well. It is expensive but once repaired its a long lasting deal. Real PITA to install the arms so do it once and be done. Put a sheet up under the dash below the wiper motor. You will drop those clips and washers and the sheet will help find them. This might be an opportunity to do the two speed and intermittent wiper system installation. Get the cowl gaskets from Carpenter as well. IMHO.
