If it's not in neutral, is there something that would stop it?

Definitely not or anything like that, it moves in and out about a 3/4" and definitively hits a metal stop or interference

I've looked as best as I'm able, it has some forward back play and spins free, no signs of a pin. What bolts normally hold the shaft on the at end? If it didn't have something holding it there nobody would be able to remove the rear section of rear drive shaft without the front half from falling out, know what I mean? Thanks for the reply.

This is the section I am addressing and referring to. Thanks.

Good morning/afternoon respectively, I'm trying to put on a drive shaft on a car that I purchased that was missing rear drive shaft. It is an automatic, so the PO left the the first joint coming off the spline on the car so that ATF wouldn't spill out and could be driven FWD. Problem is, I can't figure out how to remove it despite having a 3000+ page manual lol. Secondly, is there any way to use a WRX driveshaft from a manual transmission on an AT? I realize I can use a companion flange on the diff side, but what about the transmission side? Thank you for reading and any suggestions or direction.

Ok, thank you very much. I can't seem to figure out how to get the last section of propeller shaft from AT, I will start a new post. I think that torque bind is almost a given now based on circumstances, thanks for that. Looks like it can be relatively easy to resolve.

Anybody have any experience swapping driveshafts from an MT to AT any if the swap that mine has with the forester motor would factor in, although I don't see why it would. Or should I start a new thread? Once again, thanks to everyone for their input.

Thank you for the info, maybe I simply don't understand or didn't explain my problem very well. Ok, so I have an AT with no drive shaft at all going to the rear. I have only the small yoke piece just to prevent ATF from spilling out.

And this may be the very reason that the PO removed the driveshaft, you think that's likely? Thank you for that, I will start looking into that as well, I saw a few related postings in searching for the AT MT conversion or driveshaft interchangeability. Thoughts?

Thank you everybody for your help pointing me in the right direction. I had a few delays with the weather and holiday chores. The header has a badly pinched pipe on both side that has got to be killing my air flow tremendously. And since I recently found out that my impreza is also missing the rear drive shaft, might that play a role in it feeling very sluggish on acceleration? It is in F W D mode now. I got a manual rear drive shaft locally for a good deal, and supposedly you can adapt it to work on a AT if you swap the yoke section at the tranny end. I have no idea how the last section aka yoke, output shaft, propeller etc. If anyone has any suggestions, I'd be grateful to hear them. The AT shafts seem to be hard to find locally. If I could post pictures, I could more easily convey what I am dealing with.

Ok, thanks that is what it is and is present. The word boost on it threw me, and I didn't really know what a MAP was anyway, only familiar with MAF.

Thank you, that's kind of what I figured as far as keeping old harness, though I was under the impression that the RS was a 2.0 motor. I am going to change all the plugs and use the ones suggested for boosted vehicles as I plan to throw on a small turbo and boost no more than 9 lbs, I was also given some 440cc 3920 injectors, and a new unisia Jecs fuel pump, so might as well throw them on too. It almost seems like the PO eliminated the harness and MAF...

Hi, thanks for the reply. I have searched lots on the internet and have seen where it is, on various cars, though it does vary. Bear in mind I have a 2003 RS impreza, with a 2005 2.5 forester motor. I don't know whether the MAF harness would be the original impreza harness and exit location or wherever it routes on a forester. Either way, I can't seem to find a plug that large anywhere. The hood is a CF hood so no diagrams, not that it would matter due to the different model motor. Very frustrating... The car did not even have intake plumbing when I bought it. The car starts right up ever time and is strong, but there is much unplugged I suspect.

Thanks again for taking the time to read and post. Check engine light is on, I will pull codes again, I know there are a couple generic O2 sensor ones, maybe an IAT as well. I'll scan again though. Unfortunately, I have no history on the vehicle whatsoever. I know nothing about it. It looks like kind of a hack job although it seems that all the electrical accessories etc in the car seem to be working. I also discovered last night that the rear drive shaft is missing! Not sure why the PO would've removed it, because I wouldn't think an engine swap would necessitate changing or even removing.
