Changing Wiper Pivot Seals

Since the wiper posts rotate only 180 degrees and torque is always in the same place, all the wear is in one place. If you'll mark the pot metal housings before taking them down you can put them back rotated 180 degrees. If you install the grease fittings, those would go opposite your mark.
This removes approx' 50% of the play. Result is smoother, quieter, wipers.
