TPMS sensors have a typical lifespan of 7 to 10 years, depending on how many miles are on them. More miles, less calendar life.
When replacing a sensor, the technician should remove the old one, check the frequency (or the part number to get the frequency) and replace it with a sensor of the same frequency. Usually the sensors say right on them what the frequency is. 315Mhz and 433Mhz are the two frequencies. Newer vehicles are using 433. Some TPMS sensors are dual frequency. I've used dual frequency sensors from Autel and they have worked just fine for my cars, but I haven't used them on the F-350.
Went back Sams yesterday and got the tires rotated and rebalanced. They were out of wheel sensors so he couldn't do anything about the bad sensor. I took the truck down the Interstate for a test drive and got some pretty bad vibration at 70mph. Took the truck back and they were too busy to do another balance at the time so I rescheduled for today. On my way home yesterday I stopped at NAPA and picked up a universal wheel sensor that the guy said would sync up with Fords system. Went back today and they rebalanced the tires but said their programmer didn't recognize the sensor from NAPA but they had one in stock that would work so I had them install it. Took the truck for another test drive and all was good except the front tires were reading the wrong pressure on the TPMS screen, back tires were fine. Not really into going back to Sams again but I remember seeing a video on how to relearn the TPMS sensors by pushing the hazard light button a few times then letting the air out of the tire until the horn beeps. Will this resync the front tire sensors? I'll have to find the video. Thx.
If the TPMS sensor is working and is the right frequency, try driving for a while and see if the computer will pick up on it. As has been noted a few times in this thread, Ford's system seems to be fairly smart and the relearn often isn't necessary. I've never had to do it on my truck through all tire rotations.

Thanks Jim, you were correct. System resynced itself within a very short time period.
