This happens so often that MTH issued a service bulletin addressing the replacement. I've received quite a few of these boxes to repair the jack. If it were soldered on properly at the factory, this wouldn't be such an issue.
The arrows show where the jack should have been soldered, and the other shots show what I did to make sure it didn't come off again.
The replacement jack is Digi-Key P/N - WM3756CT-ND.
Make sure you solder both sides of the PCB where the support tabs come through, that's what was missing in the original installation.
You may also have to solder a jumper from the 5V to the jack if that trace has been ripped off the board. It goes to the pin of the chip next to the U1 designation. The other four connections are all ground, so don't worry about solder bridges between them.

How old is that service bulletin? I bought a new WIU last year. Should I be concerned that this may happen?
