    Torsen Swap ABS issues

    Ok, so maybe some of you can help me out. Recently took my rear for new bearings and while i was at it swapped the auburn carrier and 2.73s for a torsen carrier along with 3.73s.
    So when i got the car back i realized that the abs inop light was triggered. Found out the ring gear wasn't swapped over so i took it back and had the gear swapped back onto the torsen. The abs light was still on. Was then to the conclusion that the sensor is either bad or dirty, but the mechanic is now telling me it wont matter because the torsen is set up differently than the auburn and that the sensor won't line up with the ring gear.

    My guess is he doesn't want to swap the sensor and is telling me my car will never have abs again. I think that is total bull. Just wanted to see what you guys thought.

    You must have a completely different setup than our car. On ours, the rings and sensors are at the axle ends. Sounds like you have a sensor that inserts into your center section, which would be similar to what our Durango has. Is that right?

    nope, just like any other car, ring gear around the carrier
    Not too sure about cars with traction control

    That could account for the difference in design.

    The difference for the gear change is in the thickness of the carrier. When you increase the ratio your pinion gear gets smaller, thus the ring gear has to be moved closer to it by use of a thicker flange on the carrier. Another way to do it is with a spacer, which allows the use of a "2" series carrier with "3" series gears. If the reluctor ring was also moved it may not line up with the sensor.

    I guess if the mechanic says the sensor doesn't line up with the ring then thats definitely a problem. Now the question is why doesn't it line up and/or is that even a possibility??

    Figured it was something like that
    I know there are sensors are on the outsides but wasn't sure if there was one on the carrier or not. My traction control is my foot

    I didn't even know it was possible for it not to line up. Hoping someone familiar with the carriers can chime in.

    If you keep the same carrier there is no need to upgrade to a different reluctor gear. You will need a new reluctor gear when you go from a series 2 carrier to a series 3 carrier.
    and


    There are only 2 rings... one for 2-series carrier (2.73 gears) and one for 3-series carrier (3.23 and up)

    and this

    Additionally, there is an ABS sensor located on the top of the axle housing and an ABS reluctor gear that is attached to the carrier. The ABS sensor reads the reluctor gear as it turns around inside the axle. On a car with a 2 series carrier (stock 2.73), this gear is only about 1/4 inch wide. If you change to a 3 series carrier, you need a new reluctor gear which is 1/2 inch wide. If you use the old reluctor gear, your ABS INOP warning light will come on because the ABS sensor cannot read the reluctor.

    Any reason you can not simply move the sensor over? Granted, you would have to removed your cover and drill a new hole in the top of the housing, but that seems a lot simpler than taking apart the entire rear to install a new reluctor ring.

    the sensor hole is 13/16" and is smoothbore for an o-ring on the sensor assembly. It only has to be moved over about 1/4".

    Don't know, without actually removing the rear it seems easier to just pull the axles and swap the gear. I'm gonna have to pull the axles anyways when/if i get new wheel studs, figure its the best time to do it.
