4x4 looks farxfar easier to remove...more space...i dont know how you are physically meant to tighten the nuts to the head on a 2wd...its virtually impossible to get good leverage on half the nuts that are underneath...i could not even get a socket on the majority...nor a ring spanner...was cringing trying to unbolt 20 year old nuts with an open ended spanner...turbo was a bastard to...it had been mated up slightly on the piss so two nuts on one side were easy to undo and the other to were cunts
