So,
Done several things, still some shaking at "high speed"- meaning over 50,? in the 2 wd wagon. ? The wagon has the planar, cross mounted leaf spring, suspension.
Takes about half a mile for the shaking to start.? Slow down, it goes away, and starts again after another 1/2 mile of smooth operation
-
?Rebuilt steering box,? to get rid of up and down movement of sector shaft, by RedHead.? Reduced intensity of the problem
-
Replaced leaf spring "eyes" at suggestion of alignment shop, couldn't see any problem with what I replaced, no excess movement.?
-
Set drag link tightness per manual, - tighten until tight, back off one turn.? Tried tightening half a turn, perhaps some minor help.
-
Checked for loose wheel bearings, seem OK
-
Shaking wheel at 9-3 and 6-12 positions doesn't reveal any other loose or worn parts.? King pins are relatively new.
Haven't had the wheel balance checked; don't see any missing weights.? Any ideas?

Add a bolt on steering dampener. My 48 pickup did same thing

Try rotating the tires front to rear seal if anything changes

Tie rod ends? About the only sure fire ay to eliminate “death wobble” in 4x4 willyses, even after doing all you have done and more, ?is a damper between t he tie rod and axle or frame. ?It is claimed that out of balance?tires instigate the wobble.

Could out of spec "toe-in" contribute to the problem?

Was the Jeep lifted and the steering control link has a noticeable angle, should be as parallel as possible..

Have you tried a steering damper? You can also try giving it a little more toe in.

And Jay wins the award.? Front to back swap fixed the problem.? It's a case of fading memory.? When I'd done the restoration in the 90's, I replaced the tires; the Goodyear folks "graded" the rims- I? remember that the worst one became the spare.? This? time,
when the engine was out and I patched up the wheel paint- especially those critical red pin stripes- I rotated the wheels to even out tire wear, forgetting the situation from years ago.
Thanks for the suggestions, appreciate it!
