2018 Tundra SR5 Transfer case output shaft seal (front drive shaft).

2018 Transfer case- I noticed front output seal (to front drive shaft) is leaking. I went to the Toyota dealer for part but they were not sure about the part. I did find the part number between 2007 - 2013 Tundra but that part does not fit to 2018 Tundra.

Anyone done this before , part number ? what else needs to change , torque spec for the output flange nut.

I will appreciate any help and guidance to do this job.

 

Is it on this diagram?

Or one of these?

Thanks Tim, Also trying to figure out if this wok require transfer case removal or can be perform detaching the drive shaft and replace the seal. I believe the part number is 90311-A0025 but there is no associate diagram so hard to say where it goes.
