Transfer Case Leak | Please Educate

[7nJrX]

'84 FJ60 with Chevy LS and H55F swap.

Slow oil leak and pooling on ground when parked from T case.

It looks like it's coming from this wiring harness on top of the T case (see picture - zoom in close and you'll see a drop of oil starting to pool)

1) What does this wire lead to?
2) Is this a common leak point? Is it a bad washer or o-ring? Or something else?


Appreciate any help.

Those are range position sensors found on a lot of 88-newer cases (All USDM FJ62's and many 70 series). Are they actually plugged into anything on your 60? I see what looks like a twin stick shifter, someone must have replaced your transfer case's rear half at some point.

Aren't those way higher up than the transfer case oil level?
Those sensors cruisermatt mentioned are easy to tighten up a little.

That's a clean transfer case!
Sorry for that useless comment.

haha welp. @cruisermatt thanks for the confidence to pull the wire a bit and interesting to hear what that would be used for. Those indeed go nowhere on my setup (see 1st pic). And yes I've got a twin stick now (see 2nd pic)

I thought the same thing about being high up @FJ Silver 🤔 But I was able to get a small rotation with the vice grips (tough position). I'm hoping that does it 🤞

@PanhandleFJ i knowww. Fresh carwash but I promise she's seen some mud here in southern MT

Did you check the oil level in the transfer case? If it is too high it might cause a leak like that. An over full transfer case could indicate a low transmission and a leak between the two
