Driveshaft, Removing And Installing, Driveshaft Connected On Transmission Side: Removing
- Label the position of all the parts to each other before removing them. Install in the same position otherwise the imbalance will be excessive and the bearings could get damaged causing rumbling noises.
- Do not bend the driveshaft. There is a risk of damaging the protective boot in the intermediate bearing.
- If possible, remove, install and store the driveshaft in its fully extended position.
- Never let the driveshaft "just hang" during removal. Always support it.
- The driveshaft is secured to the output shaft on the bevel box with a circlip.
- Always remove or install the driveshaft horizontally from or on the centering pins on the rear final drive.
-- Remove the front noise insulation -1-. Refer to NOISE INSULATION .
-- Remove the rear section of the exhaust system. Refer to MUFFLER, REMOVING AND INSTALLING .
Incorrect handling can damage the coupling.
- Do not bend the coupling more than 10°.
- Do not load the coupling.
-- Remove the bolts -arrows and 1- and the noise insulation bracket.
-- Tie the catalytic converters up onto the underbody.
Vehicles without Particulate Filter
-- Remove the right catalytic converter by removing the nuts -arrows- and removing the clamp.
Vehicles with Particulate Filter
-- Driveshaft intermediate bearing on the right side: remove the nut -1- and remove the bracket for the Particulate Filter Differential Pressure Sensor -G1037-.
-- Driveshaft intermediate bearing on the left side: remove the nut -4- and remove the bracket for the Particulate Filter Differential Pressure Sensor 2 -G1038-.
-- Free up the wiring harnesses on the driveshaft intermediate bearing.
-- Left side: free up the wiring harnesses for the exhaust gas temperature sensor.
-- Right side: free up the wiring harnesses for the exhaust gas temperature sensor.
Continuation for All Vehicles
-- Remove the bolts -2 and 3- for the pendulum support.
-- Press the engine and transmission forward and secure with a suitable piece of wood -A-.
-- Remove the driveshaft heat shield -3-. Refer to the appropriate Service Information. .
-- Make sure there is a marking (colored dot) on the flexible disc/driveshaft and the rear final drive flange -arrows-.
-- If the mark is not present, then label the position of the flexible disc/driveshaft to the driveshaft flange on the rear final drive.
-- To loosen the driveshaft bolts, counterhold with the :T10172A and the :T10172/5 on the rear final drive.
-- Remove the driveshaft bolts -arrows- from the rear final drive.
-- Remove the bolts from the intermediate bearing -arrows-.
-- Slide the driveshaft axially together toward the front and remove it from the alignment pins on the rear final drive.
-- Place the rear section of the driveshaft on the :VAS6931 and on a wooden block.
-- Wrap the driveshaft in front of the intermediate bearing with adhesive tape and secure the :T40296 .
-- Hook the :VW771 with the :VW771/13 into the :T40296 and knock the driveshaft out toward the rear.
There is a risk of damaging the protective boot in the intermediate bearing.
- Remove, install or store the driveshaft in its fully extended position.
-- Remove the driveshaft toward the rear and fully extended, if possible.
