front end wobble???
 

Hi we were out testing tonight, a 1972 a body duster f/sa getting used to car,, in high gear after getting out of gas we are getting a pretty severe tire wobble, not during braking but out of throttle,, front end has just been aligned, steering feels tight , tire pressures are good anyone with any good ideas?? thanks in advance,, bryan

Excessive positive caster will cause a high speed shimmy. Suspension is going into jounce upon decel thus moving the lower ball joint up and the upper ball joint up and back increasing positive caster.

A decrease in the positive caster setting, or a steering dampner should resolve the issue. A stiffer shock setting that prevents nose dive may help also, but I recommend a caster setting change.

Last time I had that problem on my Demon.......lower control arm bushings were really egg shaped from coming down hard on front wheels. You may be able to see them (arms) rubbing on K .member. Jack it up and check for looseness. While you are under there look at strut rod bushings too. Both common problems on Mopars. Call me if you need to know more.
PS got all your stuff gathered up

You might also check all the connection points on the drag link for wear or being loose...
