NA_R33, that's the tailshaft, he means driveshaft from diff to hub.
Most importantly you'll need a 36mm socket and a very strong rachet with breaker bar. You can't get a 36mm separately from most hardware or automotive shops, you'll need to go to a proper tool shop or give your mechanic mate a beer in exchange for the loan of one
There's 5 bolts that hold your driveshaft to your diff, coat them in WD40 before you get started You can see the end of the driveshaft come through the centre of your hub. it has a little metal cover over the nut that you need to get off, probably with pliers. Coat big the nut in WD40, then coat it again. The 36mm fits over the driveshaft nut. This is where that maccas you had for lunch comes in handy. Put your breaker bar into the socket. You think your breaker bar is pretty big? It's not. Find something even longer to put over the end of it (i used an exhaust ) Now stand on the of the super breaker bar and you should be able to crack the nut with just your weight and maybe some bouncing. Remove the nut.
Undo the 5 nuts that hold the driveshaft to the diff. The driveshaft should now fall away from the diff but is still held by the hub on the other end. The driftshaft will need some coaxing to come out of the hub. Screw the big nut a little way back over the end of the driveshaft to give you a surface to hit against. You now need to bash the crap out of the end of the driveshaft until it goes out the back of the hub. A rubber mallet is best so that you don't damage the nut or the thread but you'll probably need even more force than that. Bash away. It will seem like the driveshaft is still held in by something but it's not, it's just a bitch. With enough bashing the driveshaft will slowly make its way out the hub and presto!, you now have a driveshaft. It may be easier in your car but at least i've prepared you for the worst.
PS. If you really want to make life hell for yourself try removing a driveshaft from a separate rear craddle with no diff or brakes. There's nothing to stop the hub from turning when you turn the 36mm nut, and even when you jam up the hub with a pole against the ground the 100 and something kg craddle would rather rotate then the nut. fun, fun, fun.... :headspin:
PSS. You sure you don't want to come remove my spare driveshaft yourself?
wow, i wrote quite a novel....
