Jlk was right. I drilled the drain hole for my ptu today and no oil came out. Everything was significantly more messy than a few months ago. Mostly from the vent not the seals. I feel like no one has documented drilling the drain plug with the ptu in the car, so I snapped a few pics. These are from an 2009. There is just enough room to work between the exhaust and motor mount. I drilled a pilot but not all the way through to keep the chips on the out side, until the end. 5/16 was enough to keep the 37/64 drill from walking. The casting is surprisingly thick. About 1/2". Do be sure to stop And oil the drill a few times. I left oil in the pan to push out the chips when I finally broke through. A 16mm socket and extension holds the back of a 3/8" npt tap and allows me to reach past the exhaust. Use grease so the chips stay on the tap and out of the case. I run npt taps about 2/3rds in. I was taught the plug should go in about 2 turns by hand before you need a wrench. And tightened an additional 2 turns with a wrench. It takes a little back and forth. Do Not cross thread the tap when putting it back in. I picked up a magnetic drain plug from mcmastercarr.com. but i'm sure amazon has them too. Do not cross thread the drain plug when putting it in.

Awesome video!

Has anyone experienced actual PTU failure? Or develop a wine? The PTU is basically a differential. When differential is worn it gets noisy and will humm at certain hwy speeds. It can be repaired by increasing the preload on the bearings or rebuilt. Metal paste on the drain plug is to be expected. There is 97K mi on my GF's 09 Edge. Some of those miles are towing. No wine. Is it sludgy? Probably. I'm getting ready to give it a douching this summer. Right now it only weeps around the passenger side seal. No smoke / puking out the vent yet.

I had my Edge at a transmission shop. He pointed out that the PTU was starting to weep. The cause is because the exhaust heat cooks the seal on the PTU. The fluid according to Ford is supposed to be "lifetime". I think the Transmission fluid was supposed to be "lifetime" as well. He recommended changing the fluid more often in both. (every 50K) Because its a bear to get to he was going to charge a pretty penny. Quoted $700 to remove the unit and change the seals and fluid.

Anyone have a procedure on changing the power steering fluid. 50K mi Service? I have an 09 Edge SE. I didn't see much DIY action in the 09 forum. Thanks!!!

Isn't there a filter to change behind the transmission pan?

Any one have luck with the chips / ECU programmers?

2 screws on each mudd flap 2 screws in the middle Where are the rivets??? Is that it?

What did you decide on for parts? What battery? Did it require a tray upgrade?
