hey guys I just notice that my rear trasfer case and shaft connecting. it leaks. not a lot but by drop. from between seals. here is pic of where it leaks.

my tranny was blown so i got new build tranny in now.
leak little from there rear transfer case and where shaft meet.

 

Looks like the rear output shaft seal. Piece of cake to replace. You have to pull the driveshaft but once you get it out, you can pull the seal out and lightly tap a new one in. Lube the inside of the driveshaft when you reassemble. Removing 4 bolts in the rear of the driveshaft allows you to push the driveshaft forward, then sideways, then towards the rear to remove.

I've replaced that one 3 times in 190K but only 1 since the nickel plated slip yolk.
