Question on Rear Drive Shaft(PICS INCLUDED)

[e30forlife]

Installing the rear drive shaft this weekend. I am a bit confused on one thing though. I kinda remember loosening something up but now that im looking at it there is no way I can reach something in their.
Does this tighten up? If so I cant get anything down their too....

Here is a pic straight on...




Now if im right I just tighten up the 4 bolts on the back to the drive shaft/diff.. And front goes to the output of the transfer case with the flex disc.

Is this correct?

Just expand it when you put it in, then the nut will be exposed.

what do you mean expand it?? What extends??

pull on the rear yoke.

Thanks for the help. Quick question though.

I cant get the shaft to extend. Ive put it in a vice grip and tried to gently hammer it out. Ive got nothing to work.

Any suggestions?

Sounds like mine! The big nut has never budged despite all effort. but the driveshaft is nice and quiet so I live with the extra work. Yank the rear halfshafts and drop the diff and you can get it back together.
