Currently dealing with the same issue ... rear drive shaft seal into the transfer case is leaking on my 2005 1kz 120 series ...
Part # 90311-43007 or 90311-41020 I believ.

Well here I am resurrecting an old thread. After installing my new ARB bash plates and transfer case guard I found my transfer case has a leak at the front drive shaft

so did a search and found this thread. I figured if I have to drain all the oil out I may as well replace the rear seal while i'm at it.
called toyota, gave them my VIN (December 2008 Build) and they sent me the below diagram



So I will pickup the following seals and give it a crack
36111b ($21.69)
36115c ($40.08)

Hi there. Based on what we've seen and read only 36115C (part #s 90311-43007 or 90311-41020 What's the second seal for 36111b for?

36115C is the rear drive shaft seal
36111B is the front drive shaft seal.

i did both when one started leaking
