As under my jeep and noticed a leak on the driver side and of course with driving blows back to the cross member. Attached is a pic, not sure what this is or how to go about fixing it.

I have read other threads with most questions asked if it was the rear main seal and blowing back and that has been fixed with this being the only spot with any oil leak. It doesn't drip on the ground just undercarriage coated.

Thanks

 

It's engine oil for sure?

 

Well I cant telling if it is tranny fluid because I have synthetic which is regular color and not a noticeable red. This is the only area so figured it has to be some part there?

 

Taste it
