Im in big trouble i think

Alright guys I decided to see if my jee sounded any good strait piped. To get to bolts to take the muffler off I take my skip plate off. I get te muffler unhooked and start it up and hear a loud thud. I look under the jeep and the transmission ad transfer case are just resting in the jack I still had under there. And my rear drive shaft snapped in the process. Someone help. Was the skid plate the only thing holding the transmission/transfer case up? It's an 01 2.5l manual tranny. All I'm looking to do right now is get the stuff back up where it should be. I'll worry about the driveshaft when I get this stuff fixed.

The motor mounts are still in tact.

Help quick.

I would say you cross member rusted out and the skid plate was carrying the weight.

Well on that note, I don't even see a crossmember. Was the skid please supposed to act as the crossmember on this? Also. I was able to get the tranny/trans case back up. Not sure it's any better. Now it's tilting up too much. Can't shift gears into 1 3 or 5

Also. Looking into it a little more. This piece if the transfer case shifter came out. Will I able to just pop that back in once the transmission is seated right?

The skidplate provides the 3rd of three support points for the engine/transmission/transfer case assembly. That third mount, called the transmission mount but which is actually bolted to the transfer case rests on and is bolted to the skidplate.

The stud that pulled out of the bracket in your second photo will likely fit back inside once you get things realigned.

So how do you recommend lining it back up? I tried putting a jack under the front of the engine in front of te engine mounts to leverage it back but no dice. Just lifted the jeep.

Jack it up at the furthest rear point of the transmission you can get a jack on, not the engine which is held by two mounts up front.

So your saying put the jack on the transmission? I already got the transmission back up bit not it is too high. It's resting on my catalytic converter up against the tub. I need it lowered back down a little bit now.

That's ok temporarily but you'll need to support the transmission from a point further forward when it is time to reinstall the skidplate.

So I can go ahead and but the skid plate back on now. But then how do get the transmission back down on the skid plate so I can bolt it down?

Sorry for the confusion. That jack stand isn't supporting anything. It's just there I case it decides to fall back down it won't go all the way to ground.

Put a wood block and jack stand under your oil pan. Take out the one you have under the transmission. Then using a floor jack raise your tcase skid back up ensuring as you go to raise it the 4 bolts for the transmission mount thing pass through there holes. Now you will be raising the transmission back into place with the t case skid using a jack. Get it back bolted to the frame and replace the 4 nuts on the transmission mount things bolts and you should be as good as can be expected. And wow dude that is something. Good luck brother.

Edit deleted this part. I see it's there already: Bolt the transmission mount and the exhaust hanger thing back to the transfer case. So ignore that.

Ok, I understand how to raise the transmission back up with the skid plate. But the transmission is to high right now and I can't get it back down. I think where my rear slip yoke shaft broke is pinching and won't let the transmission come down. I'm trying to get the rear driveshaft off right now to see if that will let the transmission come back down.

So you can pull that jack stand out by hand and the transmission will be stuck raised higher than it goes? I'm confused. It's like there has to be weight on that jack stand. Of course I wouldn't remove it until you jack stand and wood block the oil pan.

There's absolutely no weight on the jack stands. I think that right in the picture where the u joint is jammed is holding all the weight.

The jack stands are not even touching the transmission

Get a wood block and support your tranny with a jack. Get a second floor jack an lift the rear bumper. NOT The axle. That should give you room to lift the tranny further to remove your rear driveline and put the skid back on

So I tried all that. But the tranny won't go any higher. Even disconnected the sway bars to get more droop out of the axle. Still won't come loose.

That broken shaft is definitely the problem though. It won't even let my axle droop as far as it normally would.

Maybe disconnecting one side of both the lower control arms will allow the axle to pivot so you can free it. That is under some scary pressure. Maybe doing so will just push the axle on its own.

I was thinking about that. But now I think I'm just gonna take an angle grinder with a cutoff wheel to the shaft that is broken.

I wouldn't. That's a big steel baseball bat under a lot of tension brother.

I would even pull the control arm bolts while lying behind the axle for safety.

Also I don't see evidence of the shaft being broken yet. That part slips right out if you disconnect the end at the axle. It may be fine just had the opportunity to go for a walk.

I'd love to know if you got it fixed. I've been in suspense for a couple hours.
