I had an appointment at the local Ford dealership to replace the rear toe links under recall. Out of curiosity I asked how much to drain and fill my ptu, service manager came out and said 8 hours to do the job correctly. They told me the ptu has to be completely removed from the car in order to do the job..I immediately laughed in his face and asked if people actually pay that. He replied "of course, all the time". I truly hope none of you out there pay that
