I'm an idiot, but...

I think I have identified what some of the leak problem might be on my D18 xfer case. The mount kit bushings were not installed on the xfer. They were missing when I bought it, and I did not miss them until I looked closely at some FSM diagrams a couple of days ago. Ordered a new one to install when I reassemble.

I think the missing mount kit may have caused a lot to torque and twisting between the xfer and the transmission. The gasket that goes between the two units was very torn up when I pulled the xfer, and it was only 8 months old with 1500 miles on it.

Could this be some of the problem?

Also, The rear output shaft nut was stripped. I ordered a new one from Krage that came today. The nut is 3/4" and does not quite fit. I rummaged through my bolt bin and came up with a
7/8" fine thread that spins onto the shaft just like it was meant to be there.

Any thoughts out there on the differing nut problem? Could the shaft be 7/8" ?

 

they sent me the wrong one too. but it was MY fault. i didn't describe the part correctly. i think i confused both of us on the phone...
the front and the rear are different sizes for the 18 xfer case.
make sure that you are telling them the correct output shaft. seems like when i told them the name i was actually telling them the other end of the transfer case.
make sure it's a locking nut. preferably not a used one.
i did get one from herm that was correct.

 

Thanks guys.
