Should front driveshaft spin in 2wd?

No jacking required. Back to my corner

Not being comedians, just setting the facts straight in case someone in a couple years reads this with a similar problem and we don't want them to think that any kind of positive or negative pressure inside the differential housing from a plugged vent will miraculously cause the gears to spin.
Using your method of not raising the front up, how could you diagnose a seized hub only on one side condidering most front axles are an open diff?

Happy to hear that the OP found the issue.
