cj7 wiper smashed windshield frame

So the Driver Side wiper pivot arm in my 79 cj7 smashed the windshield frame hole. (See pic I beat the hole somewhat back in place). I disconnected the pivot arm from the short linkage arm off the driver side. I seen the the threads were stripped were the nut threads onto. (See pic).

So would the stripped threads cause the collapsing windshield frame hole.. Ive read there's lack of support due to thin sheet metal. Any tips on how to fix this??

I was thinking if the threads were the problem to die new threads?

Yeah, the stripped threads caused the failure.

The nut on my driver's side loosened and caused the same sheet metal buckling. I beat mine back into shape, then reinforced the sheet metal with a modified washer from the inside, then put everything back together. Fixed.

Matt,

Would it be possible to post a picture some time of your fix? I have the exact same problem and have been too frustrated to address it due to a lot of time already spent on the issue with no success. It sucks have wipers that want to work but don't! I still haven't even bent back the buckled windshield frame yet!!??!!!??

Well, I'd have to pull my dash pad off, and disassemble my wipers to show you the fix, and I don't really care to do that.

IIRC, I took a fender washer and drilled the hole to fit over the wiper stud. I also had to cut a notch so the washer would fit over the little tab on the stud. Stick the washer on the stud, then assemble the wipers as usual. It worked for mine.

My washer fix didn't last, the omix frame was just too thin. I ended up cutting the holes out of my old frame and moved them over. That was one area not rusted out.

Here's the idea, only this guy used a small piece of sheet metal to reinforce the windshield frame.

It's a common problem on CJs, with a common fix.

There was a factory recall for YJs that had wiper problems; same issues, would tweak the frame.
The factory made a reinforcement plate that you attached (read: glued) to the inside of the frame.
It was sandwiched between the pivot and w/s frame if I recall.
It had the correctly notched holes so the w/s frame didn't have to be replaced.
It was one piece construction and extended from hole to hole.
Unknown if that plate or part is still available.
It also might fit the CJ models.

Someone just gave me a couple of YJ wiper holes off his rusted frame because my passenger side one is now blown and they have those reinforcing plates on them. These ones are factory by the looks of them and about 6" long, they sandwhich between the inner and outer skin. I might just try cutting one out and see if I can fit it in behind my hole.

While I agree reinforcing the inside of the frame is good, I'm not sure it addresses the problem completely.

What I did was remove the wiper motor and elongated the 3 mounting holes so the motor and gear box would slide to the drivers side around 1/8". This solved my problem with locking up of the linkage.

While watching the linkage work and seeing it lockup, it seemed to me the passenger side was the main problem. The passenger wiper pivot was moving to far, (close to vertical) to the passenger side. Moving the motor solved this problem,
You may need to move the wipers 1 spline to make up for this.

Mine locked up the other way. I would need to move the motor toward the passenger side. I was looking at my old photos and at that time I figured the wiper pivot holes weren't in the correct place causing the binding if the frame flexed even slightly.

Turned put the threads on the pivot arm were crossed threaded badly letting the pivot arm move freely in the windshield frame.

Simple fix. Died new threads into the pivot arm. And made sure the notch was lined up with outside windshield frame.

The ends of the internal wiper arms flexed and got bent. So I had to bend them to fit onto the pivot arm shaft.

Thanks for the comments and ideas.

I ended up putting a pin running through my pivot and windshield frame, of course I also welded the notch back up and recut it for a tight fit. The pin is there to take some of the stress off of the notch.
Next time I'm going to weld the hole up, add a piece of metal behind it and find another style of wiper arm pivot to use.
