Thank you for responding.
By wiper arms, i mean the the two arms that actually hold the wiper blades.
In addition, i bought the linkage(called a wiper transmission?) that goes under the cowel on the front of the truck.
When you buy the linkage arms, you get the male pivots that go with them.
I think the problem lies in the amount of "grip" between the male pivot gear and the female ID gears on the wiper arm.
the "teeth" in these gears are small and i'm guessing the angular momentum of the wiper arms is too great for the amount of engagement between the male and female teeth--thus they slip and the passenger arm goes over the edge of the window and gets hung up.
all of these parts were brand new from one of the old truck sites on the Internet (name withheld).
There needs to be a way to SECURELY engage the wiper arm to the pivot gears attached to the linkage under the cowel. It's too bad no one mfg's these pieces with a threaded male and a nut to pinch the wiper arm onto the pivot. that might be one cure. I can think of a few other heinous ways, but i would like to have a "proper" cure (like a system from another year/model truck) that is much more robust--no southern engineering, please.
If anyone has any ideas, please dont hold back... PLEASE!
Thanks,
