Heavy popping in left rear (U's? Half shafts?)

You say up and down the driveway.
Does the noise happen going forward only ?
or backward only ?
or both?

Both.

No mention by the guy who drove it for me, following me, on the 60 mile trip home last week, at around 65mph...

It DOES resemble the clunking of a 4WD vehicle, with FRONT hubs locked, on pavement in a turn (something you're not supposed to do)...

Does not sound like a hub. Easy enough to rock the half shaft back and forth to check for slop in the U-joint. You'd want to lift such that the full weight in on the tire (ramp it up or lower it onto some wood)
