Well, I've determined there is a leak in my transfer case for my 2003 Chevy Silverado Z71 4x4. I filled up the transfer case with fresh fluid, and it proceeded to leak out fluid overnight producing a puddle about the size of a coffee cup lid. I then cleaned off the case, but now it only leaks with a couple of drips through the night. I cleaned off the fluid residue from the transfer case to try and identify the source of the leak....apparently that's easier said than done... I checked the fluid level, and see that there is still plenty in there, so now I need to determine if this leak can be fixed. I've read a few other forums about other Chevy and GMC owners who experience this issue (apparently I am not alone here!). I'm seeing residue in the two pocket areas and a drip at the tip of the case - see below pic (click on to enlarge). Any advice on how to located the leak and fix this without paying a mechanic $1K? I've heard JB Weld can help, but where would I place the epoxy?
