Gary, I didn't take any pictures, but I followed the post on pg.13 ( Used a 5/16 bit for the pilot hole. Pretty much the same location. I just took my best guess, didn't do any measuring. Took awhile to get through the casing: 1, I bought a cheap bit and 2 the casing was about an inch thick. After I broke through I let the oil drain. Went back through with a 9/16 bit, then tapped the hole with a 3/8 NPT tap, then put the fill plug in with a 5/16 hex. I put some tephlon tape around the plug just to be safe. Filled the ptu with 75w x 140 axel lube with an oil can. Drove the car about 5 miles to get the fluid moving and no leaks! Bought the plug from Grainger $6 Item # 4CCF4 Bought the same tap and die set from Harbor freight $12 Genuine Ford Fluid XY-75W140-QL SAE 75W-140 Synthetic Rear Axle Lubricant - 1 Quart $22 Hope this helps!

Just wanted to add to the discussion.... I have a 2013 Edge with 95k miles. I came across this topic and decided to change the ptu fluid imagining it has never been done. I could only siphon out about 2oz due to it being so thick. I ended up putting in a drain plug shown earlier in the thread. Put the front end of the car on jacks, drilled into the bottom of the ptu, let the oil drain for about 10mins, tapped it, put the plug in and filled it. I was surprised by how thick the casing is but overall it was a simple job and only took about 2 hours from start to cleanup. Edge is getting better gas mileage and coasts a lot better as well. I plan on changing this every 12 months which is about every other oil change.
