I am writing about a Toyota Sequoia, since there isnt a forum, I figured it is close enough to a Tundra.

Anyway, I used the 4wd today and began to notice a burnt odor in both 4wd H and L. This was the first time that I have had to use the 4wd for any extensive driving. The vehicle is a 2002.

Anyone have any ideas as to what the odor could be?

Are you on dry pavement?

No, driving in snow, several inches.

Hmmm, Maybe someone with more experience will chip in, I don't even know how these newer vehicles work anymore, but when my quad started smelling in 4wd it was just almost out of front gear oil in the transfer case/
