Ford Edge/SHO uses the same exact transfer case as the CX-9. The Ford Edge guys also have PTU failures left and right.
Always the same symptoms, very pungent burning oil smell and dark grey oil leaking.
Some of the Ford guys only replaced the seals thinking that would solve the leaking problem but they didn't change
the oil on a regular basis and were right back in the same boat again with PTU failure.
Then afterwards, they started servicing the oil regularly and all the problems went away.
Pretty much proves the culprit is the oil.
Changing the seals won't stop the leaks coming from the vent valve on top when the oil has sludged up and the PTU overheats.
They are DRILLING holes and plugging the transfer cases !!
I'll stick with Avidien's easier method of electric pump suctioning and refilling.
If you have an AWD model, change your transfer case oil, it's very easy.
Also the Ford forum mentioned the following :
"......Mazda addressed this very same issue via the addition of PTU cooling using the engine coolant system."
I'm pretty sure this is wrong information, I'm not aware of any active cooling system in the CX-9 PTU.
