Well I'm at the end of out 100,000 mile extended warranty and luckily the PTU started leaking again 900 miles short of expiration. The first replacement was at 33,000 miles. Dealer attempted replacing the seal and shaft but ended up replacing the entire unit due to internal damage. They also sent us back home with a broken boot on the lower ball joint. They had to replace that and the control arm; one piece construction. Leak appeared couple weeks ago. Dealer attempted to replace the seal (different dealer :shades: ). Upon pulling the PTU they found the housing cracked. Wonder if Ford will get this straightened out! We really love the car.
