What oil do I need to change front gearbox & front/center differentials? 98 2.8l man

[demoncamber]

Hey guys, about to do a diff and gearbox fluid change on a 98 A4 quattro manual 6.
Does front drivetrain share fluids?
Trying to get up to speed with this car as I just bought it, first time working on an awd car so, does this have a front, center and rear diff? And does the gearbox share the same fluids as the front/center diff as well?
What oil should I be buying for front and rear diff?

Thanks guys!

Automatics have ATF in tranny and gear oil in diffs 75w90

Manuals have gear oil in tranny also. Make sure you get OEM gear oil or Redline or Fuchs or something that is safe for our brass synchros in the manual tranny

Is there only one drain and fill for the front end? Or am I having to fill the gearbox, front diff and center diff separately?

One drain and fill for the front/center/trans. One for the rear. OEM or Fuchs since you have colder weather.
