Americas Check your transfer case for leaks

[PNW_IG]

I noticed a fluid leak last night while installing skid plates. Fluid had collected on the cooler lines leading to/from the transfer case... Couldn't find fluid above the soft part of the line, leads me to believe a problem with the line itself?

I thought it was a bad line as well but dealer said it was not. Another person here shared a picture that looked like mine and it was an output shaft seal. Here is a picture of what mine looked like. Any chance your rig is 8/23 build date?

Thanks, will do. How do you locate the build date?

Of course, no problem. Build date is on a sticker on the driver's door sill.

9/23 build. Does look like the TC is wet at the base where the drain plug is.

I don’t recall, sorry.

Mine was wet at the base with little clear drops coming down by the seam

But my seal was replaced and bone dry for 500 miles now.

So these failures represent a bad batch of seals , or were they incorrectly installed?

Having one with a bad front seal (successfully repaired), it appears these are all from around the same build time, so I’m strongly suspicious they had a bad batch of seals.. not an Ineos problem pre se, but rather a Tremec issue.
