Difference between A Twelve-Point Bolt with Ribs and A Twelve-Point Bolt without Ribs

The contact surfaces -arrow A- and -arrow B- are different on the two-point bolts.

1. Twelve-point bolt with ribs -arrow A-
2. Twelve-point bolt without ribs -arrow B-

Wheel Bearing Unit, Removing and Installing

Special tools and workshop equipment required

• Torque Wrench 1332 40-200Nm -VAG1332-

Removing

• Loosen the drive axle bolt on the wheel hub:
  • Twelve-point bolt with ribs.
  • Twelve-point bolt without ribs.

Caution

The wheel bearing must not be under load when the drive axle threaded connection on the wheel side is loose.

If the wheel bearings are under the load of the vehicle weight, the wheel bearing will be damaged. This reduces the service life of the wheel bearings.

The drive axle bolt may be loosened maximum 90º when the vehicle is standing on its wheels.

Vehicles without a drive axle must not be moved, otherwise the wheel bearing will be damaged. If a vehicle must be moved, be sure to note the following:

• Install an outer joint in place of the drive axle.
• Tighten the outer joint to 120 Nm.

 

• Remove the wheel.
• Remove brake caliper with brake carrier and hang on body using wire.
• Remove ABS wheel speed sensor.
• Remove the brake rotor.
• Remove the nuts -arrows- on left and right side of vehicle.
• Remove the control arm from the ball joint.
• Pull the drive axle out of the wheel hub.

• Remove the bolts -arrows-.
• Remove wheel bearing unit from wheel bearing housing.

Installing

Install in reverse order of removal.

• Install the brake caliper.
• Tighten the drive axle bolt to the wheel hub:
• Twelve-point bolt with ribs.
• Twelve-point bolt without ribs.

Caution

The vehicle must not be resting on the wheels when doing so.

When the bolt is loose, the wheel bearing can be damaged by the vehicle's weight.

Difference between A Twelve-Point Bolt with Ribs and A Twelve-Point Bolt without Ribs

The contact surfaces -arrow A- and -arrow B- are different on the two-point bolts.

1. Twelve-point bolt with ribs -arrow A-
2. Twelve-point bolt without ribs -arrow B-

• Install ABS wheel speed sensor.
• Install the wheel and tighten.

Tightening Specifications

Component	Tightening Specification
Driveshaft to wheel hub "twelve-point bolt with ribs" Use a new bolt	70 Nm + 90º
Driveshaft to wheel hub "twelve-point bolt without ribs" Use a new bolt	200 Nm +180º

Ball joint to aluminum control arm: Use new nuts Tighten only in curb weight position.	60 Nm
Ball joint to sheet steel control arm Use new nuts Tighten only in curb weight position.	100 Nm

Wheel Bearing Housing, Removing and Installing

Special tools and workshop equipment required

• Puller - Ball Joint -3287A-
• Torque Wrench 1332 40-200Nm -VAG1332-
• Engine and Gearbox Jack -VAS6931-
• Digital Torque Wrench -VAG1756A-
• Spreader Tool -3424-
• Drive Shaft Remover -T10520-

Removing

• Loosen the drive axle bolt on the wheel hub:
  • Twelve-point bolt with ribs.
  • Twelve-point bolt without ribs.

Caution

The wheel bearing must not be under load when the drive axle threaded connection on the wheel side is loose.

If the wheel bearings are under the load of the vehicle weight, the wheel bearing will be damaged. This reduces the service life of the wheel bearings.

The drive axle bolt may be loosened maximum 90º when the vehicle is standing on its wheels.

Vehicles without a drive axle must not be moved, otherwise the wheel bearing will be damaged. If a vehicle must be moved, be sure to note the following:

• Install an outer joint in place of the drive axle.
• Tighten the outer joint to 120 Nm.

 

• Remove the wheel.
• Remove brake caliper with brake carrier and hang on body using wire.
• Remove ABS wheel speed sensor.
• Remove the brake rotor.
• Now remove cover plate from wheel bearing housing.
• Loosen the nut of the tie rod end, but do not remove yet.

To protect the thread, screw the nut on the pin a few turns.

• Press off tie rod end from wheel bearing housing with Puller - Ball Joint -3287A- and then remove nut.
• Press the drive axle out of the wheel hub as far as possible (in the direction of the transmission).

If the drive axle cannot be pulled out of the wheel bearing, then the drive axle can be pushed out of the wheel bearing using the Drive Shaft Remover -T10520-.

Before using the Drive Shaft Remover -T10520-, make sure that the thrust piece -1- is installed.

Using the Drive Shaft Remover -T10520-:

• Secure the Drive Shaft Remover -T10520--1- with three wheel bolts -2- on the wheel hub, so that the drive axle -3- can be pressed out.

• Follow the specified sequence exactly.

1. Tighten the knurled nut -1- hand-tight.
2. Only turn the bolt -2- using a wrench and press out the drive axle using the Drive Shaft Remover -T10520-.

Note

At the end of the tasks or to set back, the spindles must be brought back into the original position so that the hydraulic operation can be used.

• Remove the threaded connection on the wheel bearing housing/suspension strut -arrow-.

• Insert Spreader Tool -3424- into wheel bearing housing slot.
• Turn the ratchet 90º and remove it from the Spreader Tool -3424-.

• Loosen the nuts -arrows-.
• Now place the Engine and Gearbox Jack -VAS6931- under the wheel bearing housing.
• First press off ball joint from control arm in order to then pull off the wheel bearing housing from suspension strut.

Installing

Install in reverse order of removal. Note the following:

• Tighten the drive axle bolt to the wheel hub:
  • Twelve-point bolt with ribs.
  • Twelve-point bolt without ribs.

Caution

The vehicle must not be resting on the wheels when doing so.

When the bolt is loose, the wheel bearing can be damaged by the vehicle's weight.

Difference between A Twelve-Point Bolt with Ribs and A Twelve-Point Bolt without Ribs

The contact surfaces -arrow A- and -arrow B- are different on the two-point bolts.

1. Twelve-point bolt with ribs -arrow A-
2. Twelve-point bolt without ribs -arrow B-

If the wheel bearing housing was replaced, the vehicle must be aligned.

• Install the wheel and tighten.
