The first linkage goes from wiper motor all the way across to the left pivot post. Second linkage goes from there back across to drive the right pivot. So all the work load is on the first linkage and that left pivot. Replacing all the bushings alone requires removing the inst' panel and the glove box liner. And you'll likely do this every 2 or 3 years. To do it once and be done for many years longer, buy linkage bushings and pivot seal kits. Mark the pivots with a sharpie before removing. Reseal per instructions provided with those kits, reinstall rotated 180 degrees from where they were ( 2 bolt housings make them symmetrical ).
