PTU Leak/Fill

Recommended Posts

I have a 2009 Limited AWD with 63K miles on it. I looked under it and I see what I think is the PTU leaking. Can anyone confirm if the first picture is a leaking PTU and if the second picture shows the bolts to remove to drain and fill it?

Ok, did more searching on the net and found out:

 

1. My first picture I posted is a good example of a leaking PTU.

2. I don't think my second posting is how you change/check the fluid. A writer someplace else indicated that it is a "pipe" type plug and right above the "Y" in the exhaust.

 

Also found the following on our fourm:

 

"There is a pipe plug in the PTU directly above the "Y" in the exhaust.

Removing this plug with a typical 3/8 drive ratchet allows checking the fluid level.

Ford suggests taking a Zip-Tie, and bending it at a right angle, and trimming the short leg of the zip tie (after bending) to 1 3/4 inch.With vehicle level (I put it up on 4 ramps for convenience), insert the short leg of the zip tie down the fill hole.

Fluid level should be between the bottom of the dipstick (1 3/4" below fill hole) and 1 1/2" below fill hole.

 

On my car, it is overfilled by more than 1/2 inch, and I suspect this can be contributing to seal leakage.

Because there is no drain plug, I have to pick up a suction gun to draw the level down.

 

For those that are low on fluid, Ford recommends their synthetic 75w-140 gear lube (for topping it off, or replacing fluid). "

 

Also found the attached TSB:

It is totally the PTU. Mine looked exactly like that. Its an oily black fluid, not red and it smells god awful. Its a problem with AWD Edges but not big enough for ford to do anything. http://smokinedge.com/

 

They replaced it first with an after market part that didnt even make it home. Then they tried to fix the after market part and the seal didnt hold either. They finally spent the money on an oem ford part and its held up fine for the last 20k miles.
