I need help please...what is this?

I've been to autozone and advanced auto parts and we can't figure out what this is...it came off my transfer case near the rear output shaft...its causing a massive fluid leak and needs replaced...i've crawled the fourm and can't seem to find anything...the best we could come up with is a speed sensor...but i know theres a speed sensor on the transmission and we pulled up speed sensor on their computer and it wasn't the same thing...this is really killing me so any advice would help...thank you

It goes in the transfer case I believe, because we Rubicon owners have an electronic speed sensor. Not a gear in the t-case like all the other jeeps.

The rubicon speed sensor is not gear driven like the regular jeeps, its an "electronic" sensor. Basically its a hall effect type sensor - as something on the transfer case output shaft comes close to the sensor, it detects a "revolution" - from those pulses it calculates speed.

No matter what Wrangler you have, rubicon or not, the sensors are at the rear of the transfer case. On a 2 wheel drive vehicle, it would be at the rear of the trans. They were looking up the wrong vehicle and/or part.

But - all you should need to replace is the o-ring on it. The do go bad and need replacing - shouldnt need to replace the whole sensor!

Yeah what he said. If you were to open your tcase up you would see that just below that there is a metal ring and as the ring turn that sensor allows the PCM to calculate speed. From the looks of the sensor I see no reason to replace it just put a new o ring on it and bolt it back on.

It's not the oring that's messed up it's the plastic grove the oring sits in that's messed up...not sure how it happened but the plastic got bent up somehow creating a gap and replacing the oring won't fix the problem...but thank you all for your quick and helpful responses

Try some black rtv on the plastic then place the o ring on. Tighten it down and test drive. If that dosent work I'd look into a new one.
