Grinding maybe stuck in 4X4?

I went to try this today but the bolt on the trunnion is sheared off so it's turned into a bigger job. This all started happening after I hit a mound of gravel my township left in the middle of the road without cones on it while I was in 2h. I was driving back and forth in my driveway shifting the transfer case to 2h back to 4h and nothing was happening. While I was moving I pulled out onto the road and did a U-turn very slowly in the intersection (I'm way out in the country) and it was hopping and bucking as if it was stuck in 4h. So, I'm thinking I've lost 2h. It works perfectly fine without the front drive shaft in. I don't have any funny noises or anything, nothing seems broken I'm just stuck in 4h now. I can shift down to 4L it works forward and backwards no noises (didn't try turning for obvious reasons). So, my conclusion is I've somehow lost 2h after hitting that mound.

Okay. So, I drilled it out today and tried to adjust it, she's seized in there so I just grabbed the shift lever myself from underneath and put it into 2h myself that did nothing so I just put everything back together. When my wife shifts the transfer case from in the cab and I'm underneath it all looks and sounds fine, but it's still stuck in 4h.

So, I've got 4low and 4hi but I don't have 2h. I'm at a loss I made sure it was in 2h on the transfer case. It works perfectly fine at highway speeds without the front drive shaft so what do you think could be causing it not to want to go back to 2h.

What I mean by the bypass is I'm pretty sure the last owner told me he did an actuator bypass that locks both the front axles together all the time so there's no need to use the vacuum lines.

I've never had any issues until I hit this mound of dirt.

I've decided just to go through insurance at this point since i hit something on the road and it's starting to cost too much for me to pay out of pocket, i will update you with what was wrong with it.

to explain the bypass, you open the actuator and there's a fork in there that locks the hubs together if you swap the snap ring from right to left it keeps the hubs always locked and then when you shift with the transfer case 2h and 4h are instant without the need for the vacuum lines to actuate the forks anymore

Here's a video on it if you'd like to learn how it's done.
