wiper motor straining on return to park

I have a 92 yj and I just replaced the windshield frame and windshield. When I put the motor back on and hooked everything up the first time I failed to test it before i reattached the roll bars, hard top, etc., and put the wipers on. When I ran the wipers the first time, they went from park to full extension fine, but on the way back, they froze at the top of the path, so the wipers were totally vertical. I took it all apart again, reattached the wiper linkages, and it actually moves now but when it gets to the top of the path on the return, it hesitates badly. Video below. You can see that the motor actually torques in its mount. Does anyone know what's going on here?

As an update, after attaching the wipers, the adding friction makes it so that it basically stops before continuing the trail. When the motor is totally separated from the linkages, there is no hesitation in the movement, so I'm assuming it's a problem with the way I put it back together. I've searched but haven't found great pictures of how things are supposed to go back together, and of course I didn't take pictures before I pulled it all apart.

So I figured this out. My replacement windshield was not built to the same specs that the original was, so every time the wiper motor arm was going around it was slamming into the frame itself. I was able to grind out the frame and that fixed the issue.
