... also, the rotating wiper arm shafts that pass through the wuper shaft housings (and through the) bulkhead firewall wear on the rotating shaft and can leak.
The rotating wiper shaft passes through a metal assembly. The interface is treated with a grease at the factory. The grease gets displaced.

I need to replace these wiper shaft grommets, as it leaks for the left and right wiper arm shaft, and apply a grease to the assembly.

The gap between the rotating shaft and housing.
Mobil 1 15W50. If dashcap removed and you are replacing the fan motor or servicing the wiper system, may be best to use an NLGI 2 grease. I mean to try SuperLube brand NLGI 2 silicon synthetic grease as it far less deleterious to robber bits like the grommets.
Or your wiper may honk as Art shows in this video:
Though an older wiper shaft housing used up to the early 80's here.
Can't find some images on BrickPix. Can't find my post like this I made before.
Hopefully not a rusted windshield pinch weld like (not the worst example):
Hope that helps.
