Help with leak on transfer case!

Hey guys,

This has been like this since I bought the truck and I really want to get this sorted out. To me it looks like the speedometer cable is the culprit here as it seems the most damp around that area. However, if this is the problem is it an easy fix?

Thanks,
Cory

 

Anyone?

 

Please help me out guys, I really want to get this fixed!

 

looks like the rear "pinion seal" if i am saying or seeing that right....
you need to clean it up real good and see exactly where it is coming from...
mabye someone with more exp. will chime in

 

Sorry no help here--It does look as if it has been rebuilt--viewing the silicone sealer(orange). Did you make sure everything is TIGHT? How bad is it leaking? Or is it just discolored--In my opinion from the rebuild?
When you purchased-did they say anything about the transfer case?

 

Hi, Could be speedo or could be pinion seal. Might be an old leak perhaps that is just wet looking.

First thing I'd do is get some good degreaser in there and clean everything up good and clean. That way you can at least tell where any leak is coming from. Don't be tempted to pull the orange FIPG if it is sticking out along the edges.

Trying to remember back when I had everything out of mine (5 speed), but I think there is a vent pipe up there somewhere up top as well. I might not be remembering this right as been a while now, but seem to remember it connects to the main shift housing on the 5 speed.

Either way, clean everything up and go from there. If it is the speedo cable then most are sealed with an O ring. I'd have to relook at the FSM etc to double check, but I'm sure before I can, someone else will hop on and confirm or not.

If it is actively leaking, have you checked the level lately??

 

Hit it hard with brake cleaner and get all that shit off it. In a day or so have another look and see specifically where the fresh oil/grease is coming from. Might be a good start.

 

toyo uses orange from the factory

 

Thanks for the input guys, I will get everything cleaned up and see how things turn out. If it is the pinion seal is it easy to replace?

 

This. And possible could be the pinion

 

It could also be seeping from the shifter. The other side of the pinion seal is dry

 

^This. This is what mine did. Pulled the shifter boot to the 4x4, replaced the paper gaskets (two of them between the thin sheet of medal) cleaned the surfaces, and used yotas orange gasket shit. Worked like a champ.

But clean her up to figure where she's leaking.

 

Did you ever figure it out?
Sorry I'm no help, have same issue right now.
Whats the proper name for this part?

 

I agree with the others saying it's the shifter. Pull the center console off and then the shift boot and you will see the top of the case.

 

Replace the o-ring on the odometer drive housing, very simple and cured my leak. I would replace the pinion seal as well. The orange/red sealant is factory.

 

In addition to all of the above I would verify that the vent hoses are clear. IIRC, the vent hoses for the front diff and transfer case come up by the vacuum booster on the firewall... My 4X4 is out of town or I would run out and take a picture.
