How crafty are you. Get a mic and measure it accurately. Go to Mc master on line and order one. Or try Dorman on line. A good auto parts might have a Dorman catalog yet. Most don't have counter people who can use a catalog. With exceptions.
I don't think the wiper motor on my truck is strong enough to strip out the wiper arms. The wipers slow way down on a dry windshield, or on the downstroke when on the highway at speed.
If so, I have no problem using JB Weld, or soldering them on. In all my years of driving across many, many vehicles...I've never had to replace a wiper arm.
Interesting - I never knew those things were called Woodruff Keys. They fell out on my 2 previous F150’s. I used silicone to glue them back in and never had another issue with them.
Just happened to my 2021 a few weeks ago. Dusting of snow melted and froze again. Grabbed the wiper just the smallest bit and now it hits the hood. Did not see the key though. What a terrible design.
I got a 2021 f350 dually and had some ice frozen on the side of the windshield where my wipers stop. Well my drivers side wiper came up and hit it and kinda skipped. Then I noticed when I turned my wiper off it went too far and hit my hood. I popped my wiper off and moved a few teeth dn put back on. Problem solved right....... got a 1/2" of snow on my windshield and when I got in and turned my wipers on it stripped the teeth out of my wiper arm. They are on back order and cant go without a wiper so I put the passenger wiper on the driver's side but the first time I went to use it it skipped too. Took the wiper arm off and the teeth are starting to get stripped. I don't get what's going on, it's a brand new truck. I've never even heard of a wiper arm stripping out. Here in northern michigan you sometime forget to turn your wipers off and when you turn the key on the wiper motor is no match to the 6"-8" inches on the windshield. Anyone info on what I can do or what to look for would be greatly appreciated.
Here a is quick search open source old find on one of the F 150 forums same concern.
Unless something has changed and I could be wrong, the woodruff key is used for “production only” as noted below. It also say it does not need to be reinstalled. If it allows you to sleep better reinstall it.
And yes, naturally any windshield wiper(s) frozen in place onto the w/s could potentially strip out. Just keep them lifted off the w/s when parking in snow country. One of the many reasons I am glad I don’t live in snow country. I do like our land of long summers and very short winters.
So those truly experienced with snow country DO NOT leave their wipers up. Sure sign you have come from "somewhere else"...LOL Leaving your wipers up like that hyper extends the spring and you lose down pressure the spring was intended to provide to help clear the windshield. Terrible advice to leave them up for any period of time.
Mine made it through a Colorado winter, and I use the truck to plow snow so rest assured I used the wipers a fair amount. It would seem obvious if your wipers are frozen down, and quite simple to lift them briefly to make sure they are free before running the wiper motor. My truck also lives in a heated garage because I do not own vehicles I can not properly house. I mean maybe they are weak but seems like a lot of user error occurring too.

Pretty sure that's a myth created by lazy/and or short people not smart enough to flip them up.
Leave your wipers flipped up sometime during a heavy snow and ice event that packs the underside of the arm and spring with solid ice. You won't make that mistake again. Flipping them up is one of those things that sounds good on the surface but if you drive in heavy snow and ice daily, you'll probably realize it's better to leave them down on the windshield and protected. A quick 'pop' to lift them when you scrape the windshield while your truck warms up, and then flip them back down and off you go.
