Rear Final Drive

Rear Final Drive

Short Description

- Prior to removal, print out a diagnostic protocol. Send back the removed final drive with the protocol in the usual manner.

Before raising the vehicle, two holes must be made in the luggage compartment floor. The locations for drilling are marked by the factory. These holes allow access to the final drive/subframe fastening bolts located below.

The pendulum support is unbolted from the transmission at the front. The stabilizer bar is removed, the drive axles are disconnected from the final drive. Electrical connections and ventilation lines are disconnect from the final drive.

The rear part of the exhaust system is removed. Remove the driveshaft from the final drive, move it the top and secure it there.

The final drive is lowered with the transmission jack downward diagonally in the direction of travel.

- Disconnect the exhaust system at the clamping sleeve - arrows - and remove the rear exhaust system component.






- Remove the noise insulation below the engine/transmission.

- Remove the pendulum support to transmission bolts - 1 and 2 -.






In order not to damage the left rear level control system sensor (G76) :

- Disconnect the harness connector, remove the sensor and lay it on the control arm - A -.






- Loosen but do not remove the intermediate bearing bolts - arrows -.






- Press the engine/transmission forward by hand and secure this position with a suitable piece of wood - A -.






So that noises due to an imbalance do not occur later:

- See if there is a mar (colored dot) on the rear flexible disc and rear final drive input flange - arrows -. If not, mark the position of the flexible disc and rear final drive input flange with respect to one another - arrows -.






- Remove the rear flexible disc to rear final drive input flange bolts - arrows -.






- Remove the driveshaft from the rear final drive, and guide it upward in the center until it is under the fuel tank - 2 -. In this position, support it using tunnel brace - 1 - and a suitable piece of wood.







When doing this, be careful not to push in the fuel tank - 2 -.

When removing and installing the drive axles, the final drive must be moveable in the rear area.

- Lift the final drive - A - in the rear - arrow 1 - and push it as far as possible to the right - arrow 2 -.






- Remove the left drive axle - B - from the flange and carefully lower it.

- Put the final drive back into its installed position.

- Disconnect the right drive axle from the final drive.

- Lift the final drive - A - in the rear - arrow 1 - and push it as far as possible to the left - arrow 2 -.






- Remove the right drive axle - B - from the flange and carefully lower it.

- Put the final drive back into its installed position.

- Support the final drive using the engine/transmission jack (V.A.G 1383 A) and use the strap to secure it to the universal support to prevent falling.

- Remove the bolt - arrow - for the front bracket.






You must replace this bolt later.

- Remove the washer - C - on top of the bracket.

- Disconnect the harness connector - A - from the all wheel drive control module (J492).






- Remove the vent lines - arrows - from the final drive.

- To remove, lower the final drive more and pull forward, while ensuring that there is sufficient clearance with respect to other components.

Installing

- Secure the final drive against falling down with the universal support strap.

- Move the final drive in the position shown.






- Lift the final drive, and move the rear bushings - arrows - above the subframe while ensuring sufficient clearance with respect to the other components.






- Connect the harness connector - A - to the all wheel drive control module.






- Slide the vent lines - arrows - onto the final drive vent tubes.

- Lift the final drive using the transmission jack into the installed position.

- Place the washer - C - on the front bracket.






When removing and installing the drive axles, the final drive must be moveable in the rear area.

- Loosen the front bolt by hand; do not loosen it more than 5 turns.






- Remove the transmission jack from under the vehicle.

- Lift the final drive - A - in the rear - arrow 1 - and push it as far as possible to the left - arrow 2 -.
