The distinctive feature of these wheel bearings is that one of the two seals on the bearing has a built-in magnetic impulse wheel. Caution should be taken to make sure that the seal with the ABS impulse ring is installed in the correct direction.
The side with the impulse ring needs to be installed closest to the ABS sensor. If it is installed backward, the ABS system will not function.
The side with the ABS ring can be identified either by placing a lightweight metallic object (such as a paper clip) to the magnetic side or by a close visual inspection. The close visual inspection will reveal the ABS impulse ring windows, which can be seen through the seal surface. Care should be used when handling and installing the bearing so that the impulse ring is not damaged. If this occurs, the ABS system will not function correctly.
