ALUMINUM HUB BEARING REMOVAL SET
INSTRUCTIONS
This tool has been specially developed to disassemble the hub and wheel bearing housing on multi-link axles of VAG
vehicles.
Suitable for wheel hubs-bearings separated in two parts where the wheel hub and bearing are disassembled
separately.
IT IS NOT NECESSARY TO REMOVE THE STEERING KNUCKLE BUT IT IS POSSIBLE TO OPERATE DIRECTLY ON THE
VEHICLE!
The problem: the steel wheel bearing housing is usually extremely tight compared to the aluminium axle, which makes
it much more difficult to remove. When working with a hammer puller, there is a risk that various components will be
damaged. In addition, working without proper equipment could generate fine cracks in the aluminium axle that could
cause unwanted breakage.
The solution: with the help of this special tool, components can be removed carefully and quickly directly on the
vehicle. In addition, different bearing sizes are covered, see the application list.

REMOVING THE WHEEL HUB
To better illustrate the work steps, the following images show the replacement of the wheel bearing on a workbench.
The tool is also designed to be used directly on the vehicle.
On some models it is necessary to slightly loosen the wheel bearing housing screws (Fig. 1) before removing the
wheel hub, as the thread protrudes too much. (Fig.2)
This is important in order to position the half rings on the component.
Note: to work in better conditions, the side plate / sheet (Fig. 2 - A) should also be removed, if possible.
