This may help you to understand how the Ford/Lincoln AWD works.

Thanks for this.

you have to have loss of traction in essence to engage the rear wheels in this AWD system. this is not fulltime AWD, only on demand/as needed.

 

you can track the AWD behavior using Forscan Lite and an OBD adapter on your smartphone/tablet.  there is no display for it until 2015MY IIRC.

 

how many miles on your Edge? maintenance history on the PTU and RDU? yes, the fluids need to be maintained.  the PTU is a gear driven unit, the RDU has an electronically controlled clutch that determines how much power is sent to it.

Thanks for the reply. Mileage is 205000 kms.  The PTU was serviced a month ago with fluid change and drain hole tapped and plug installed.

Hello to the group.  I have a 2010 Edge SEL with All Wheel drive. Last winter, there were times that I questioned whether all wheels were being powered- due to poor handling and performance in relatively small amounts of snow and ice. With summer time driving, of course- I do not notice this feeling any more. Question- is there a simple way to determine if power is going to the rear wheels? Can I lift the front and rear of the car off the ground and manually turn each wheel to determine if the other wheels are turning? What should I expect to find if everything is working? Thanks in advance for any thoughts.

Hello to the group and good day. I own a 2010 Edge SEL with 205000 kilometers on it.  I also own a 2010 Honda CR-V but I wanted a heavier SUV to tow a trailer. My Edge has a factory towing package and it was the detail that led me to choose this car over the others I had been looking at.  When I got the Edge, it was starting to show signs of corrosion damage underneath- we use salt and a brine solution on our winter roads here. I had it undercoated last Fall and will have it done again this spring. Since then, I replaced a power steering line due to it's rusty appearance and expected failure if I did not. I have already had the PTU drilled and tapped for a drain plug at a local shop. They also replaced the PTU oil.

I believe in sharing past experiences with the group thinking that someone else can benefit from it.
