Audi Workshop Service and Repair Manuals

Removing and installing propshaft with bolted connection at gearbox end Special tools and workshop equipment required

t  Assembly tool -3139-

t  Counterhold tool -T10172- with adapters -T10172/5-

t  Engine and gearbox jack -V.A.G 1383 A- with universal support -V.A.G 1359/2- t  High-temperature grease -G 000 633- Removing propshaft t  Observe notes → Chapter. t  Repairs on the propshaft should be carried out on a two pillar hoist.   Note

The flexible pipe connection (de-coupling element) in the front exhaust pipe must not be bent more than 10° - otherwise it can be damaged. –  Unfasten clamp(s) -arrows- and disconnect exhaust system. –  Tie front exhaust pipe(s) up to side of underbody.

–  Remove rear section of exhaust system -2- → Rep. gr.26.   Note A second mechanic is required for removing the rear section of the exhaust system. Audi A4, Audi A5 –  Remove cross member -1-. –  Detach heat shield -3- from body -arrows-.

Audi Q5 –  Remove front cross member -2- and rear cross member -3-. –  Detach heat shield -1- from body.

Continued for all vehicles –  If fitted, detach heat shield -A- from gearbox -arrows-.

–  Check whether there is a factory marking (coloured dot) -arrow A- and -arrow B- on the propshaft and on the propshaft flange on the rear final drive. –  If one of these markings is no longer visible (for example -arrow A- on the propshaft), make a new coloured marking accordingly. l  The markings on the propshaft -arrow A- and on the rear final drive -arrow B- should be aligned.

–  Attach assembly tool -3139- and tighten plastic nuts.   Note Do not fit assembly tool onto balance plates.

–  Remove bolts -arrows- securing centre bearing.

–  Remove securing bolts from connection between propshaft and gearbox (counterhold using counterhold tool -T10172- with -T10172/5-). –  Remove propshaft from gearbox and support propshaft with engine and gearbox jack -V.A.G 1383 A-.

–  Remove bolts -1- (6x) on rear CV joint. –  Use counterhold tool -T10172- with adapters -T10172/5-. –  Remove the propshaft.   Note The propshaft must be kept straight when it is stored or transported. Installing propshaft Perform installation in reverse sequence of removal. Note the following: t  Remove old, dried-out high-temperature grease from CV joints and flanges for propshaft. Put in exactly the same quantity of fresh high-temperature grease -G 000 633-. t  Clean all remaining locking fluid out of the tapped holes in the propshaft flange shafts on the gearbox and rear final drive. The threads can be cleaned with a thread tap. Otherwise the securing bolts can shear off when they are screwed in. t  After detaching the propshaft from the rear final drive, the additional balancing washer (thicker washer) that may be fitted between the lock plate and one of the securing bolts must not be reinstalled. t  Always install new securing bolts for propshaft (self-locking bolts). t  Note correct position of propshaft: the central CV joint is located behind the centre bearing and towards the rear final drive. t  Check for damage to gasket for propshaft on rear final drive flange and on gearbox (kinked gasket or partially detached rubber coating). A damaged gasket must be renewed.

–  Fit propshaft, paying attention to installation position at rear final drive: l  The markings on the propshaft -arrow A- and on the rear final drive -arrow B- should be aligned. l  Maximum misalignment of markings: 30°. –  Screw in new bolts by hand until they make contact, but do not tighten.

–  Screw in securing bolts -arrows- so that centre bearing can still be moved.

–  Tighten bolts -1- at rear of propshaft. Follow correct tightening sequence → Fig..

–  Tighten bolts securing propshaft (front end). Tightening torque → Item –  Remove assembly tool -3139-. –  Secure centre propshaft bearing to body so it is free of stress and tighten. Tightening torque → Item

–  If fitted, bolt heat shield -A- onto gearbox -arrows-. Tightening torque → Fig.

–  Install heat shield -1-. –  If fitted, install front cross member -2- and rear cross member -3- → Rep. gr.66. –  Install exhaust system and perform stress-free alignment → Rep. gr.26.
