    After having the first pinhole patched by the dealer it's still going strong about 4 years later. However, I just found a 2nd pinhole. I'll be plugging it with JB weld too.

    A few years ago I reinforced the transfer case on my 03 by applying some stick-epoxy putty to all the pump-rub wear points. It wasn't leaking at the time but I thought making the areas of the case that wear through about 3/8" thicker could prevent a leak. At 103kmi so far so good..
