Oil Leak but from where?
 
Hey Guys,
Any clues on where this fluid leak. Looks like motor oil is coming from?

B4 I remove the shield plates looking for suggestions on where to start probing. My rig is a H3 2006 with 103k on the ticker.

See 4 pics

Does it smell like diff fluid, output shaft seal? Btw, windows photos has an editor option.

Thanks for those suggestions. Will need to put the rig up pull the shields and turn a few wrenches possible dependent on whats up.

Its not a bad leak so may wait for next oil change to perform.

OK follow up pulled off the shields and inspected.

Look a little wet in two locations. 1) Where the CV shaft seal enters the housing 2) Under the Power steering ram housing.

Suspect the Shaft seal since the gear reservoir

was low and needed a few ounces of gear oil. It had been changed and filled only 5k miles ago.

Truth
 
OK after looking again this AM the leak has been identified as the Shaft Seal. As suggested by one of the Guru's here.

Thanks to all. Now to find someone to fix this. Beyond my skill set.

And you'll get the PS bushing rectified also? ;)

Good call. The bushings will move with fluid intrusion, it's replacement time.
