Final Drive, Differential (01VA Transmission)

Center Differential

(Transmission installed)

Special tools, testers and auxiliary items required

• Engine/transmission lifter (VAG1383A) with universal transmission holder (VAG1359/2)

Removing

- Remove front exhaust system with catalytic converter.

- Remove heat shield for driveshaft from cover for Torsen differential (arrows).





- Remove driveshaft - 1 - from transmission and let rest on heat shield - 2 -.





- Secure driveshaft using wire (arrow) to bracket - 3 - of fuel lines or support driveshaft using engine/transmission hoist (VAG1383A).

- Drain center differential gear oil. Refer to => [ Center Differential Gear Oil, Changing or Filling ] Center Differential Gear Oil, Changing or Filling.

- Loosen mounting bolts - A - and - C - for transfer housing - 2 - in diagonal sequence and remove.





- Do not remove bolts - B -.

CAUTION!
Carefully pull center differential housing off of transmission toward rear. The Torsen differential could otherwise fall out of the transmission.

- Pull Torsen differential off output shaft toward rear.





Installing

Installation is reverse of removal, noting the following:

- Check for presence of dowel sleeves (arrows - A - and - B -).





- Install gasket

• Lightly coat sealing surface -D- with gear oil to prevent the seal from slipping.

- Slide cleaned magnets into cast holding pocket - 1 - in intermediate flange.

- Add 200 ml. gear oil to output housing (comparable to gear oil, topping up on removed and disassembled center differential => [ B - Center differential was
removed and disassembled ] Center Differential Gear Oil, Changing or Filling).

- Install Torsen differential onto splines of output shaft and bottom spur gear while turning slowly.





- Check whether installed Torsen differential can be turned by hand.

- Install fully assembled transfer housing with installed spur gears and drive flange/drive shaft onto transmission flange.





- Insert bolts - A - and - C - for transfer housing - 2 - and tighten to final tightening torque in diagonal sequence in several stages.

- Bolt driveshaft to output flange/driveshaft.

- Install front exhaust system with catalytic converter.

- Fill transfer housing with gear oil and check oil level. Refer to => [ Center Differential Gear Oil, Changing or Filling ] Center Differential Gear Oil, Changing or Filling.
