if you have the im shaft pulley removed, the carrier is underneath. its right there now. the seal carrier. you seem to have removed it. i think now the shaft can come out some, what im asking is im not 100% sure if the shaft has the same end-play lip as earlier models. i think it does, or is similar.
some of the older models (mk1, & mk2. the old IDIs) that lip on the shaft that controls end-play, could just separate from the shaft. then again a lot of these cars had quite a few miles on them.
id check this lip first.
i pulled an im shaft or two on older mk2s. its a chore. i dont know if you have enough space with the mk3 fender. that large inner fender 'lip', that the air box sits on.
what i did for an older mk2. front tire off. oil pan off. using a jack and a few blocks of wood. i think i jacked the motor up (& then down) on the oil pan lip about where the front timing (& seal) cover is. loosen the main bolts on the other two motor/trans mounts. not all the way! loosen the bolts on the center mount. i think theres one on/from top and one lower. jack motor. see if jack support holds. remove the center bolts. jack motor. you should be able to get enough space where you can get the mount out. if you can, you may be in luck.
carefully lower/rotate motor, hopefully you will have enough space where you clear the fender. if so you can remove that im shaft. and be able to put one back in!
if thats you amount of work for now. itd be best to raise motor slowly, so you can put mount back in. so while you figure out what else to do, make plans, etc, the motor will be secure.
if its a bearing. id consider disassembling the motor as needed (before), and towing/or flatbed to a good shop to have them extract (both!?) bearings and press in new.
among other things, at the least the oil pump comes out, and vacuum pump.
