Transfer Case 4WD Sensor

What size socket do I need to remove the transfer case 4WD or "position sensor?" Does anyone know?

Mine's in the wrong position--it reads 4WD in 2WD. (It's in position 2 when it should be in position 1.) I've confirmed the problem and I'm trying to go through the floor pan to remove it and then re-seat it deeper.

Thanks for your help.

1 1/2" deep socket

For the record, the Transfer Case Position Sensor is 1 1/2"
I was able to remove it through the floor pan without much difficulty. Just remove the transfer case shifter (lift really--I never removed it entirely). The sensor is located right there on top of the transfer case.

For me, it was easier to go through the floor pan than to remove the skid plate and long arms that were in the way down below.

BTW, thanks to the Jeep parts dept because they allowed me to measure a new position sensor with a caliper--without buying!

Are you talking about the switch for the "4WD" indicator? I just did this not too long ago and I'm pretty sure I didn't use a huge 1-1/2" deep socket to remove it. I think I used a 7/8".

Here's a pic by another member:

I should clarify: the 1 1/2" is for an NV241 Rock Trac transfer case. Other TC's may have different sized sensors. I know the Rubicon sensor is 1 1/2".

Yeah, I just had to do mine in a 231 case, and it definitely wasn't that big, probably 7/8 like another member said. I didn't have to pull anything apart either, I did it from under the Jeep, with a box wrench.
