Crap, I have some kind of an oil leak! (Transfer case output flange)

[MTNDOG]

I was thinking the same thing.

1) Anyway to catch this at PDI? I am not too shy to crawl underneath and have a look when I go pick mine up.
2) What are the build dates of the ones that are leaking and is there more than 2 that we know of?

1) seems to take a few hundred miles for the leak to become apparent, but I’d still peek.
2) mine was august build date (delivery in late December)

I'm not sure that you'd see this at PDI, as they are fairly "fresh" off the boat, and definitely not with many miles on them. If it was leaking enough to be seen (like in the photos above), it would absolutely be caught at the PDI

As of about a week ago the only transfer case leaks in the US reported to dealers/Ineos were on this forum, so the overall numbers are quite small

I noticed a bit of oil leaking under my grenadier recently, not sure what it is. Any advice?

Have you noticed any drips on the floor. Mine had what I thought was a leak in the same spot. It was the same color as what you have, but was more like a grease than oil. I wiped it off and has not come back in a couple hundred miles.

That oil appears to be motor oil. It could be dripping down from the oil filter, and tracking along the motor. Try and trace up the motor to find the leak. Or start on top of motor and look for where it looks dry, to where oil is present. Check all sides of motor. Looks like dripping down on starter motor. Could be coming from bell housing, and rear main shaft seal.

Thanks, I wiped clean all the spots I can see and reach, will see if it will leak around the same spot tomorrow. The funny part is that I only noticed the leak after watching this great review

which motivated me to crawl under the car to take a closer look

It seems to be that I have a leak at the front differential. Noticed some small spots of oil on the floor, so I took a closer look. See pictures.
It's getting real Defender looks now, it's starts to piss my driveway.... But it's a bit soon, only have > 26000 km now.

You are at the leading edge of learning how well the Grenadier can keep oil IN.

I have the same and couldn’t get it fixed in Southern Africa as apparently a special tool is required that they didn’t have.

 

[Voader - Oudersopzwier]

So it isn’t fixed yet. I am afraid that once they want to fix this, the car will be a time out. And that would be a problem for me. Well we will see on Thursday when the car goes to the dealer for some other fixes.

This transfer case leak is becoming more common. I’m curious why only North American vehicles are beginning to see this issue while I haven’t seen reports of this out of Europe/aus/nz in 2023.

My transfer case (AUS vehicle) appears to also be leaking so its not limited to only US cars. Looks like its the TC front output shaft seal others have been reporting here.

I think Temec had a batch of bad seals. Mine was a 12/23 delivery in the US. Manufactured about 08/23.
It was definitely the font output shaft seal.
They only had for a day to fix it (not a big job).
Can’t really blame Inoes as they buy the transfer cases from Tremec

Just noticed this older tread. Just toe give you guys an update. When the car went in for his second oil change, they also fixed this leak. Just a joint, no big job. All under warranty.
