PTO started leaking out of the vent, notcied some drops on the floor. Had the fluid changed, but unfortunately is too late. Time for a new PTO. Recommend changing fluid every 25k or so.

Actually Alberta Canada...not MN. PTU leaking and dripping on exhaust. $1100 to fix all seals, $2000 to replace unit. And that's a discount on the unit because I know the parts management! Would be $2400+to joe-shmoe....How is this justified? Ford! How is this justified?

Heard a grinding sound. Took the car into Monarch Ford (Exeter, CA) they said the problem was with front axle struts, sound did not go away. Then then reshaped the right rear rotor. Sound did not go away. Then my tenant noticed an oil spot after we left for the weekly 250 mile trip to the ranch. We then got back from the ranch we discovered that the vehicle was leaking more. Called Monarch Ford again and they insisted that the front axle lube was thick and would not drip. This is in direct conflict with your website and now they are checking your website.

Had the seal replace less than a year ago. It's leaking again, and now the dealer says the seals are fine; but it needs a new PTU to the tune of $1,700.00. Frustrating that such a great car, has such crappy dealer service.

Power Transfer Unit Leaked. It seems that either the leak or some other event caused the internal casing to burn up. now the unit has to be replaced at a cost of ~$1400
