Ok, so I have a rear differential with a sensor on top, and one without. They are both Vv-6 differentials and both 4.56 gears. Why is there a difference? Similar years, 1990-1995 4Runners. Are they interchangeable? Problems or codes that would come about? What does the sensor do?

Thanks!

well for one, that top differential looks like it's out of a front axle..
note the front driveline shaped rust mark on the pinion flange.

the one with the sensor is for ABS...

the sensor is ABS..... yes they are interchangeable.... but if you HAVE abs and no abs sensor your light will come one.. i just removed the bulb.

cant be a front.... its a v6 housing..

reading fail xD
nvm guys.
still thought, that flange looks suspiciously like it had a front driveline bolted to it..

I personally removed the one you are questioning out of a rear axle. I sold it to a gentleman already. I found another one that I picked up, now I was just curious about the sensor. Didnt know if it was a pressure sensor or ABS. ABS makes sense. My old explorer had a sensor in the same place on the Rear Diff.

Thanks for the help!

the sensor on the ford is actually the speedo sensor, fords do that for some reason. their goofy

not on that 99 explorer. It was bad, speedo still worked. It was the ABS sensor.
