As for the torque spec.... this is also debatable....because of the crush sleeve.
Before you take the pinion nut off you should of marked it with something and the pinion itself so as to get in back to where it is supose to be. If you do this you dont have to worry about torque spec just mark nut/pinion, pull nut off replace pinion seal and replace nut to where it was.
If you did not mark the pinion nut posistion on the pinion before you removed it you will probally have to pull it back off and get a new crush sleeve from the dealer and pinion nut. Place crush sleeve around pinion under the seal , replace pinion seal , and replace pinion nut and torque to factory spec.
note; the crush sleeve is alumiun and if tightened to much or to less it may cause damage/ leaking from pinion seal.
hope this helps.
and i'll have the factory torque spec for the 2004 D35 pinion nut in a few minutes for you.
