Yesterday when I pulled out of the garage, I noticed there was some type of fluid that had accumulated under the front passenger wheel. It is a oil of some type, not water. I can not see any leaking under the truck at all, really stumped as to where it came from. Could it be from a brake line? There were no other spots of oil anywhere, only directly under the tire? Suggestions as to where to look? TIA

 

Color of oil? Picture?

 

really it can leak from lots of places and gravity takes it where it wants...

Only thing i can think of on the front passenger is a leaking shock or brake line...maybe a turbo, not sure of your engine. The AC drains up there so might be really dirty?

Pic of oil, what color is it, what does it smell like, and if its leaking to leave a puddle you shold be able to see it

 

Look under and on top of the lower control arm for oil wetness. I recently had my struts replaced. The passenger side shock was leaking leaving a few drips of oil on the driveway.

 

My guess would be oil filter adaptor gasket. Mine did nearly the exact thing and that's what it turned out to be. It's doable at home but being 4x4 makes it very tight to get to.
