Do you know what the "new part number" is? I bought a 2018 about a month ago. It is a single owner truck, well taken care of and always only serviced at Ford, so I requested all of the service tickets. The phasers have been replaced 3 separate times using the HL3Z...CD part numbers each time. It also had the PCM updated before the most recent phaser replacement. Currently not making any phaser noise so I'm hopeful the root cause has been addressed but it does seem to lend credence to the idea that some have posted on here of the PCM update being the real fix and not the parts alone.
