Pull and recheck. O-ring could be not seated correctly or split.

I am multi-talented, I can talk and piss you off at the same time.

X2 probably seated incorrectly. Pull it back out and try again

If you didn't do the swap yourself, it's not impossible the mechanic forgot to put on the o-ring, especially if you are really leaking as opposed to a slight drip.

Either way, you need to pull the speedo-gear and check if it's not seated right, missing, or perhaps damaged during the install.

Funny story, the previous owner of my jeep decided to save some $ and put silicon around the speedo-gear instead of using an o-ring. It didn't leak, but what a mess it was to remove when I put in the right size gear.

Sooo after driving all over the place looking for the right size speedometer gear o ring I finally settled for the dealer. I get back, try and put it on, and the housing doesn't even want to go in all the way!! So, thinking that if I screw down the black tab around it that it would push down, I did so. IT DID NOT TIGHTEN FLUSH TO THE TRANSFER CASE! What the F am I doing wrong? I'm so pissed. Now I have to get another 5 dollar o ring because all of the auto parts stores and hardware stores I've been to, don't carry the exact size according to the specs off Stu-offroad.

Did you lubricate the "O" ring with transmission fluid?...

Gone but not forgotten.

The housing is clocked so the gear could be contacting the output shaft.

Orient it like this

Then twist to this position


And like said above, ATF the o ring

There's some markings on the top of the gear sensor that orient it. I don't remember the specifics, but depending on the size of the gear it goes in with the markings (I think) at 12, 4 or 8 oclock, and this changes the distance that the gear will sit from the gears inside the housing. (Some gears have more teeth and are bigger)

If you don't know what I'm talking about, then this is why you can't get your speedo gear in all the way. You are probably in the wrong orientation and the gear isn't fitting. In the other wrong orientation (Since there are 3 options I believe) your gear would go in but not contact the one in the housing. Make sure you get this right or you'll need to do this all over again.

This video on youtube (https://www.youtube.com/watch?v=YSefvew3XUc) helped me understand the process. There are others too.
