OP said: "I've found that I can almost always cure the seizure by parking in a slot from which I can conduct a tightly arcing turn in reverse, put it forward gear, and go on as if nothing ever happened-- sometimes for many miles."
This sounds like a problem with the suspension, not a CV joint. Does it matter which direction you do the "arcing turn in reverse" ? I'd wager it probably does.
Inner drivers tend to make noise under engine load (driving forward), due to the way they wear. Neutral throttle, or engine braking usually produces no noise.
Outer CVs will click for a LONG time, getting progressively louder, until the cage completely falls apart, and the balls fall out of the races, and you're stuck on the side of the NJ turnpike 35 miles from home, facing a $275 towing bill (as me how I know...). They can be noisier in turns, but eventually will click almost continually.
In any case, if the suspension is firmly attached to the car, bad CVs or inner drivers won't do anything like what you describe.
What this sounds more like to me is a ball joint (though you said they were replaced), a bushing, or a structural problem. Rust at the lower control arm attach points is a well known issue, so you should look for that, both from above, and from below.
There have also been cases of the lower control arms breaking, usually in reverse. This was quite common in some areas of the US (I, personally, have never experienced it in the Northeast, but I don't doubt it happens/ed). I can't recall if it was one side over the other or not.
Things to check:
Check that the rack is tightly fastened down to the body (4 nuts holding the U-clamps down)...
Check that all of the upper and lower control arm bolts and bushings are tight...
Check the spring perch bushing on the upper control arm for tightness, and a good bushing
Examine all of the control arms for cracks or excessive rust.
And, of course, check the area around the control arms for structural rust.
Good luck!
