Ok....
So swapped in a different spring, that didn't work...
So here's another question...
Both of my '92 F-150's came with wiper arms that have the PIN mount blade type.
I'm looking and wondering why it says '80-90 pin mount and '92-96 hook type?
Is there really any advantage to either style?
I'm going to purchase NOS wiper arms.
During our recent snow I paid more attention to my chatter problem.
I told her to get out.
No, really, darn things chatter in both directions. If it's a steady rain they don't. I may try a Mr. Eraser. The blades are recent, Michelin's. Maybe Michelin blades are crappy, IDK.
So I'm wondering what the tension is at the end of the arm where the blade assembly is attached? This would be measured with a spring scale attached where the blade is attached. Reading would be taken just as the blade started to lift from the windshield. Does the newer version of the arm require more pressure to lift the blade?
Well, I swapped out my arm with the '95 project truck, that did not wipe well!!!
Missed 8" of spray sitting still. I'll have to swap the other arm from the project truck and see if maybe it's just a fluke. That arm from the project truck is bad from the passenger side is my guess. The truck hasn't ran since being bought, so I'll have to dig a little deeper.
Personally I have never had any kind of luck with the newer style one piece flexible wiper blades on 80/90s trucks, they would never conform to the windshield and would tend to float at highway speed, The best luck I had with my trucks was to go down in size 2" with the old-style metal framed wiper blade.
Take some rubbing alcohol and a terry cloth and soak the cloth and wipe the blades down. You'd be surprised of all the dirt on the rubber. May take 3-4 wipes to get clean. Once the rubber wiper is clean, you shouldn't have chatter. Even when I get new blades, I still clean them. Try it it works.

Ditto. I tried every brand and style of wiper blade (and headlight bulb, but that's another thread) when I was getting them for cost. Every single one of them worked worse than the $4 anco blades.
Although twisting the arm has me intrigued. Hadn't thought of that. My driver side chatters a little bit now, chalked it up to the blade going bad. May have to try that.
Hey, glad I popped back to this thread to report what I found. You guys have a ton of good info!
FWIW, I took the advice about bending the arm a little. Used an adjustable wrench to bend the flat part of the arm, holding it up near where the blade attaches. It's not perfect, but it is MUCH better. The bladed still doesn't wipe the water perfectly over the entire area (driver's side), but I was able to make it so the crappy area happens only on the lower portion near the end of the stroke (when the blade is near vertical) - way out of my field of view.
Amazing how sensitive the "wipe quality" is to the angle of that arm, but twisting it I got the bad spot moving in all different places. If you have this problem, it's definitely worth trying to twist the wiper arm a little.
Like "Absloute" said it's not the pressure of the blade on the windshield. It's the ability of the blade to flip so the blade is dragged instead of being pushed in the direction of the wipe. It's a real dealer fix too to adjust the twist of the wiper arm and not the pressure. Having used this fix many times over the years I'd use an adjustable wrench instead of pliers. The wrench grab firmlywill not slip or gouge the wiper arm metal and you'll get a better twist, you won't have to squeeze and twist at the same time.
