Ok here is goes: I need to sign in and unload somewhere because I am done with Ford. I have an 08 for EDGE AWD that started to stink about three months ago after I had the drive train components serviced by a local shop not a Dealer. I took the car back to my service shop that had changed my PTU oil, they recommended that I take it to the best transmission shop in town so I did. The owner took me in the back room and showed me 2- 55 gallon drums full of PTU units from the Tarsus, Flex and Edge AWD vehicles. /This is what he said: The transfer case/PTU sits in a very harsh extremely high temp location next to the catalytic converter in all these cars and has no shield to keep the heat off the PTU. Every car that he had worked on needed a new PTU because the oil was gone out the seal or out the vent. He pulled my PTU out and split the case and said it was not damaged but was close to being trashed. Placed a new seal in the PTU drilled a drain hole and added a vent hose extending the vent up three ft. He also fabricated a heat shield . I really trust this guy because he created a solution to the original problem. He told me to off the car and get something else. I am going to take his advice and do that. I really love this car and it has performed for me in heavy show and many bad roads in the Sierra's. It has seen two ft of snow for 10 miles and never flinched. Ford will need to come up with a better solution and stop lying to there customers. If you have a warranty use it have it fixed and off the car. I hope that before people purchase these cars they read these posts.
