Noticed today that a very small amount of gear oil has been leaking out of the breathers located under the hood. Both caps spin and appear to work. Changed front diff and T case fluid 10K ago.
I use 4x4 on a weekly basis, and drove almost 150 miles in 4x4 the other day when the roads were awful. And it has been super cold lately (-20 with 0 degree highs)
Is this normal for a small amount of oil to be around this area?? (no drips, just oil spots on the surrounding metal and the breather tube?
