Note.
- Mounting tool -MP6-414 (3253) - must be installed perpendicular to the axis of the wheel hub with the wheel bearing. During removal and pressing, do not jam the wheel hub with the wheel bearing.
- The following describes 2 different possibilities for pressing out a wheel bearing with a wheel hub.
Insert the knockout tool for the side door hinge pins -3- into the space between the wheel bearing cover and the wheel hub as a contact surface for the assembly tool -2-.
Press the wheel hub with wheel bearing out of the wheel bearing housing cover.
- 1) -MP6-414/2- with -MP6-414/5-
- 2) -MP6-414/1-
- 3) -MP8-605/1-
- 4) -MP6-414/10-
- 5) -MP6-414/6-
Note.
- Instead of the tool for knocking out the pins of the side door hinges -MP8-605/1- it is also possible to use two washers (thickness approx. 25 mm, height approx. 40 mm and length approx. 220 mm), located in the space between the wheel bearing cover and the wheel hub and serving as a contact surface for the mounting tool -MP6-414 (3253) -. Location according to release tool -E-37-.
- If the release tool -E-37- from the accessory set -VAG 1459 B/2- is available, it can be used as contact surface. When doing so, ensure that the correct assembly position is maintained. The flat surfaces of the pads should point towards the wheel hub.
Install the release tool -3- in the space between the wheel bearing cover and the wheel hub and pre-tension it.
Press the wheel hub with wheel bearing out of the wheel bearing housing cover.
- 1) -MP6-414/2- with -MP6-414-
- 2) -MP6-414/1-
- 3) release tool -E-37- from VAG 1459 B/2
- 4) -MP6-414/10-
- 5) -MP6-414/6-
Note. Clean bore of wheel bearing cap. Lubricate the hole with Molykot grease -G 052 723 A2- over the entire area.

Attention.
- The wheel bolts must not (2) protruded on the back side of the pads (3).
- The illustration below shows the installation of a wheel hub with a wheel bearing on the wheel bearing cap on a running gear with FS-III brakes.
- The selection and definition of the special tool for fitting the wheel hub with wheel bearing into the wheel bearing cap on the running gear with FS-II and C54 brakes, respectively, is the same as for the running gear with FS-III brakes.
- The wheel hub must not be wedged during pressing with the wheel bearing.
Press the wheel hub with wheel bearing into the wheel bearing cap.
- 1) -MR 6-414/5-
- 2) -T10064/1-
