The module that plugs in near the top of the T-case seems to be leaking from it's seal....any one ever replace one of these? Is the seal hard to find?

ok I believe this is the module for the 4wd indicator light. I'm looking around the net and this seal does not appear to be easy to locate.

UPDATE: So it turns out the switch is mounted on an adapter that plugs into the T-case, there is supposed to be an o-ring there and there was not. All you have to do is take out that back bolt which holds down a retaining clip and the whole thing pops right out.

Eh? That picture is of the speedometer sensor, the 4WD sensor is located near the shift linkage on the left side of where it bolts to the tranny

could you possibly take a picture of this clip and what the inside of the o ring looks like? mine is leaking bad in the same spot.

well I guess that was the speedo housing then...oops...lol.....
Like I said you just undo the back bolt (the one that FreeGDR drew a red arrow to), and that whole set-up pulls right out, now right where the adapter meets the t-case there was no o-ring, I installed one and now the leak appears to have stopped. When you pull it out there will be a shaft with a gear on the end of it, you slide the o-ring over that shaft all the way to the base of it,it's real simple nothing complicated. I had my father-in-law find the o-ring for me, he is a parts manager for Tucson Dodge.
part #6035709 for the o-ring
