Started with original front end and never got it still I put the drop axel . I have the correct shims as far as if the axle is accurately where it should be thats a no. Yes I bias plys and have been messing with the pressure, does work. I have quite a bit of play , so next step is steering box. Then I guess I'll try wheels and tires.

Frankly I can't follow how you got to this point. Did you start with an original front end? Rebuild it with a dropped axle and then develop a wobble? Have you checked the caster? Usually dropped axles take out a bit of caster due to frame angle. Too little as well as too much caster can cause a "speed wobble" Same king pin angle on both ends? Dropping an axle isn't rocket science but it's not an eyeball deal either. Loose steering,tire pressure, tire type(bias or radial) can all play a part also. Often it's a combination.
I can't see from your original description on the jack problem of doing excessive damage to a spindle and since you've ruled out a wheel/rim cause and all steering linkage is tight, (ie gear box, drag link, tie rods and kingpins ) I have to assume( there's that word again) you have alignment issues of which a dropped axle and/or suspension will need proper alignment to compensate or corrected to.
Excessive positive caster and or toe can exaggerate front end in-stability .
