97 tacoma burning smell in 4X4

What is it's recent service history? How many miles?

When you say "hot burning smell," what does it smell like? Wood? chemical? burning oil? rubber?

Hi there...

The truck has 160,000 km. The burning smell is similar to the smell emitted when driving with your parking break engaged. I guess i would classify it as a rubber or oil smell.

any ideas would be helpful. thanks

Any work, i.e., oil change, etc. done lately?

Ray,

I have been changing the oil on my own consistently, but the smell has been persistant. It occurs all the time, so i don?t think it would be oil dripping on the manifold or anything. I should mention that I have changed the fluid in my rear diff since acquiring the truck but have not touched the front one due to the difficulty in accessing it and my laziness.

thks again

Without smelling the odor, I'm stumped. The only things I can think of that might give off a burning smell only in 4WD are:

Oil level in the transfer case too low with insufficient lubrication; Oil in the transfer case too high, coming out a breather hole; Something in the front diff slipping and burning.
