Audi Workshop Service and Repair Manuals

Installing propshaft with detachable centre bearing (up to 05.07) Installation is carried out in reverse sequence; note the following:   Note t  All parts of the propshaft marked in relation to each other must be reinstalled in the same position.

t  The seals -arrow- in flanges of the propshaft must not be damaged when removing and installing. If seals are damaged, the propshaft must be renewed. t  Ensure propshaft is horizontal when pushing it onto centring pin. Installation position: t  Three projecting sleeves on the gearbox flange / rear final drive flange and propshaft flange engage in mounting holes of flexible coupling.

–  Attach propshaft to rear final drive so that the markings -arrows- align.

Take note of the correct fitting locations for the various flange bolts.

Flange bolt with	Fitting location
small collar -arrow A-	Propshaft to front final drive -A-. Tightening torque → Item
large collar -arrow B-	Propshaft to rear final drive -B-. Tightening torque → Item

Make sure that the markings on the constant velocity joint/propshaft -arrow A- and -arrow B- are in line.

–  Secure front propshaft tube to rear propshaft tube -arrows-. Tightening torque → Item

Stress-free installation of centre bearing: l  Make sure that all propshaft bolts have been tightened. –  Position the centre bearing in its elongated holes so that the propshaft and centre bearing are not under stress. –  Tighten bolts with washers -1-. Make sure the bolts with washers -1- are within the four centring tabs on heat shield -2-. Tightening torque → Item

–  First secure pendulum support to gearbox -arrows B and C-, then on subframe -arrow A-.

Component		Nm
Pendulum support to:	Gearbox -arrows B and C-	40 Nm + 90° 1)
	Subframe -arrow A-	100 Nm + 90° 1)
1) Renew bolts

–  Install exhaust system and perform stress-free alignment → Rep. gr.26. –  If fitted, install cross member on underbody -arrows- → Rep. gr.26. –  Install noise insulation → Rep. gr.66.   Note

t  If droning noises occur during driving, note the following: t  Remove balancing nut and balancing washer -arrows-. t  Then, if necessary, unbolt propshaft with flexible coupling from flange for propshaft on rear final drive, rotate one hole further and screw in again. t  If the droning noises can still be heard, the propshaft must again be rotated and screwed back on.
