t  Remover -3283 A- Carry out the following work: Removing –  Lift vehicle far enough to take weight off front axle. –  Loosen twelve-point nut for drive shaft.   Caution Wheel bearings must not be subjected to load after bolt securing drive shaft to wheel hub has been loosened. If wheel bearings are loaded with weight of vehicle, wheel bearings will be damaged and service life of wheel bearings will be considerably reduced. It is not permissible to turn drive shaft bolt more than 90° anti-clockwise if vehicle is standing on its wheels. Do not attempt to move the vehicle without the drive shafts fitted as this would damage the wheel bearing. If a vehicle nevertheless has to be moved, comply with the following: t  Install an outer joint instead of the drive shaft. t  Tighten outer joint to 120 Nm. –  Loosen wheel bolts. –  Raise vehicle. –  Remove wheel.

–  Remove hexagon nut -1- from coupling rod (left and right sides). –  Pull out coupling rod -3- from anti-roll bar -2- on left and right side.

–  Remove nuts -arrows-. –  Pull swivel joint out of suspension link. –  Pull drive shaft out of wheel hub. If the drive shaft cannot be pulled out of the wheel bearing by hand, use press tool -3283 A-.

Before using press tool -3283 A- ensure that thrust piece -1- is inserted.

Using press tool -3283 A-: –  Secure press tool -3283 A--1- with two wheel bolts to wheel hub.

–  It is essential to follow specified sequence. I -  Tighten knurled nut -1- hand-tight. II -  Only turn press tool -3283 A- by means of bolt -2- using a spanner in order to press out drive shaft.   Note At the end of the procedure or for pressing out drive shaft further the spindle must be moved to its original position in order to deploy the hydraulic force! –  Secure drive shaft to body with wire. The drive shaft must not hang down under its own weight. Otherwise the inner joint will be bent too far and will be damaged. –  Remove brake caliper and tie to body using wire → Brake systems; Rep. gr.46. –  Remove bolt for brake disc and remove brake disc. –  Remove splash plate for brakes. –  Remove ABS speed sensor → Brake systems; Rep. gr.45.   Note Place engine/gearbox jack -V.A.G 1383/A- underneath (danger of accident from parts dropping out when wheel hub and wheel bearing are pulled out).

Press out wheel hub

–	Fit gripping pieces -T10064/6A--1- to wheel hub.

–	Screw wheel bolt -2- into wheel hub and secure lower gripping piece -T10064/6A-.

–	Install tools as shown in illustration and preload hydraulic press -VAS 6178-.

It must be ensured that the wheel bolt -arrow- and bridge -8- are offset.

Pulling bearing inner race off wheel hub 1 -  Puller, e.g. -Kukko 18/0- 2 -  Thrust piece -3002- 3 -  Inner bearing race 4 -  Separating tool, e.g. -Kukko 17/1- 5 -  Wheel hub Installing –  Clean bore of wheel bearing housing.

–  Fully coat bore with Molypaste -G 052 723 A2-. Use grease sachet from repair kit.

Pressing in wheel bearing

Make sure it is installed in correct position:

The black ring of wheel bearing must face towards wheel bearing housing (inside of vehicle).

Press in wheel hub to stop.

Make sure that deflector ring -1- is clipped completely onto outer joint.   Note t  The lugs of deflector ring -1- must face towards outer joint. t  Deflector ring -1- must lie on contact surface of outer joint -arrow-.   Note

If deflector ring -1- is not positioned correctly or if it fell off outer joint, it must be driven onto outer joint to stop using thrust piece -T10049-. –  Guide outer joint into wheel hub splines of wheel hub as far as possible.
