This is a leak that has been digging me for months. I finally pressure washed under the truck and pinpointed the main leak I'm after to the seal where the front prop shaft enters the transfer box. What is this seal called? I now have the rave and plan to tackle myself. Any advice appreciated. Below is a pic, sorry for the flashlight and cell photography.
Thanks guys.

 

Oh, and I have put a bottle of white shepherd in with no luck. The worst is its dripping on the exhaust and smells pretty bad.

 

this thing?

Output Shaft Oil Seal For Land Rovers - Part # FTC4939

 

I think so. The pic didn't work last time, can you confirm by this terrible picture?

 

Mine drips. But I determined it would take many many miles to drain it.
I just check it every 6 months and top it off.

I put cardboard under the truck in the garage.

yeah, putting it off but..

 

It's called the transfer case front output shaft seal and is easy to replace.

 

You might want to inspect the flange shaft and make sure there are no groves warn into it, if there are, you should replace the front flange cause it will just start leaking again.

 

If the surface of the flange the seal rides on is grooved there may be a Speedi-Sleeve that fits.
I forgot to mention that you'll need a new nylock nut for the oupput shaft.
I'll see if I can get one measured tomorrow to see if there's one that will fit.
Ok, it looks like Speedi-Sleeve PN 99177 may be correct. YMMV

 

Thank you, that would be great. Are there any specialty tools I need for this?

 

Torque wrench.
