Front Wheel Bearing

Recommended Posts

Hey all! Need your assistance on bearing installation.

I removed the carriage following the DIY posted by DASBoost, however, looking at the photos, not sure which way bearing should be installed. The photo from DASBoost shows the black side of the bearing facing the inward, but my carriage shows the "orange/rubber" part of the bearing facing inward.

Which part of the bearing should face inward? Or does it matter? I took it to a couple of Porsche independent shops and had 2 different answers.

Depends on the cars MY and the used ABS sensor type, hubs equipped with a toothed ring use an induction sensor, in this case there should no problem with the bearing. Later cars use a different type of ABS sensor and a bearing which is magnetic on one side, the magnetic side should be on the inner side of the carrier. ( closest to the measurement surface of the sensor )

Thanks for the info. My car is a 2001 TT. This is the type of ABS Sensor I have in my car.

That is the older one which is used together with a toothed hub, no problems with the bearing possition in this case.

Here is a very good write up on replacing front wheel bearings on a 996 turbo. Lots of good pics. He suggests that the red/orange seal goes toward the inside of the car.

Good luck,

Joel

Thank you for the link. I've finished installing the bearing on one side of the car with the red/orange seal towards the outside of the car.

I wonder if this will present any future problems? I'd have to do more research before I continue.......Thanks again!

 I'm about to replace front and rear wheel bearings.  Should I get sets from Porsche ( Porsche OEM included) or is there a better or preferential set. 

 

Keep in mind this is my daily driver ( I hate slow traffic ).
