M1 75w90 2000 Tundra transfer case 120k

[cheetahdriver]

my next 4 posts will be prime examples of how smart (ok, never been SUCCESSFULLY accused) people can do stupid things. when i bought the Tundra in 2000, i had all of the oils shifted to syn at 3k. then i went along thinking i had it whupped until 100k, got busy and let things go to 120k. while i probably didn't do much damage, i went way over what i should have.

well, at least you changed it early on in life and used synthetic....

900ppm wear is pushing it especially with the built in failure points of some Toyota transfer cases.

You should consider a 30k rinse run on all your fluids.
