Information
“Service 4 wheel drive system” warning light came on and all 4-wheel drive options became inop. Clicking from tranny area. Took it to dealer and they said it threw code U040300. They wanted to replace the ABS module, which wasn’t covered by my drive train warranty. But it sure seems like a drive train issue. I didn’t let them do it because I wanted to check into if further. Doesn’t any body have any information on the clicking as it might relate to the U040300 code?

Sounds like a bad transfer case motor clicking!

Differential issues of my own.
I have an 07 Grand Cherokee limited. Noticed the drivers side axel seal leaking. Drove to auto parts store to get gear oil and it jumped out of gear. Won't go in any gear. Only grinds when trying to put in anything other than neutral. Front diff pouring fluid. Any ideas of what I should do? Cv has a lot of play
