Theres 2 sensors on the top of my axle, I assume on is traction control, I couldnt guess the other....what are you guys doing with them? Are you leaving them in there, or plugging the holes somehow?

 

I would also like to know, I just got a 94 rear end and there's a sensor right on top, no idea what it goes too.

 

I have been using a 4th gen rear for 5 or 6 years now. If theres no leaks from the wire connecters just forget about them. The one that lines up with the toothed ring on the carrier is the traction controller. Dont know about the second connecter. Maybe a temperature sensor?

 

can it b abs???

 

I have a 94 diff in mine and just left the sensors there and so far have had no problems.
