Looks like I need a new PTU....

[glock-coma]

A little progress today, new one is installed. Still need a flex pipe but I got all the gaskets needed in the mail today.
While I was waiting for my trans fluid to drain I decided to open up the damaged ptu....I was not expecting so much destruction.
Notice how clean the interior is, no sludge or burnt fluid.
One of the bearings completely disintegrated chewing up most of the gears.

That is some carnage!  Probably a design failure that theoretically is corrected by the G revision.  What was the revision on the old PTU?

The old one was revision D
according to the work order from 5/2013

IDK if this is new or not...if it isn't new, I wasn't aware they make a repair kit for the PTU...

Apr 11 2018  6329 - 2007-2016 Various Vehicles - All Wheel Drive (AWD) - Propane Or Natural Gas Odor During Idle Or Low Speed Driving - Built On Or Before 30-Jun-2016

Some 2007-2016 Edge/MKX/Flex/MKT/MKZ/MKS/Taurus/Police Interceptor Sedan/Explorer/Police Interceptor Utility vehicles equipped with AWD and built on or before 30-Jun-2016 may exhibit a propane or natural gas odor during idle or low speed driving. This may be due to break down of the power transfer unit (PTU) fluid caused by excessive heat. If the source of the odor is identified as originating from the PTU, an idler bearing repair kit is available to repair the PTU.

The part number for this kit is
GB5Z-7P258-A it’s approx $315

I have a family member that works at a dealer, I’ll see if he can order and take pics of the kit to see what’s included.

She's back up and running, been about a week since I completed the install.
Didn't want to post to early and jinx it lol.

No leaks, but she needs an alignment again.
I had to remove the right strut/knuckle assembly.

Also tried to do a lot of heat mitigation to prevent or slow down future issues.
Wrapped the new stock down pipes and applied some
Reflective heat barrier on the ptu in strategic locations.

I'm working on gather all my part numbers and pictures
I'll attempt a "how to" but it might be awhile before I can complete it.

Noicely done, and I am sure the effort will pay off bigtime.

Nice Job! I did the same kind of thing with my truck after having long tube headers on for a few years. Trans was getting hot so I wrapped the pipes and it has solved the issue since. Looking forward to the "How to"!
