Front wheel drive cars
Signs of damaged bearings include: noise when turning sharp turns; heavy wheel movement when the brake is released. Wheel bearings can only be installed using a special device. The bearing is destroyed as a result of removal, so it must be replaced.
Removal
1. Remove the caliper and rear brake disc, refer to the subsection Removal and installation the brake disc/caliper.
2. Loosen the twelve-sided nut securing the wheel to the hub.
Warning: Set the socket wrench arm horizontally to the left to prevent the vehicle from sliding sideways off the stands when loosening the nut. Risk of accident!
3. Remove the bearing/hub assembly from the journal using a puller (A).
4. Remove the remaining bearing race from the hub using a standard puller with a clamp (A).
Warning: Be careful not to damage the ABS sensor.
Installation
1. The wheel bearing/hub unit is replaced only as a set. A special device AUDI-3429 is used for installation. As a result of screwing the device onto the journal, the wheel bearing/hub unit is pressed on. Remove the device again.
2. Screw on a new twelve-sided nut and thus pull the hub until it stops. Tighten the nut to a torque of 175 Nm.
Warning: Set the socket wrench lever horizontally to the right to prevent the nipple from being caught when tightening the nut
3. Install the caliper and brake disc, refer to the subsection Removal and installation the brake disc/caliper.
