Looking for help, or ideas.

I know alot of stuff is getting thrown at you, but...
Another way to ck for a loose ball joint, or suspension is to jack up the wheel from under the lower control arm.
This will keep the torsion bar acting as if the wheel was on flat ground.
If you jack up from the frame, the torsion bar will unload and take up the slack (wherever it may be).
Then wiggle the tire from the 3 and 9 o'clock position, back and forth.
Also in and out from the 12 and 6 o'clock positions.
You should be able to see whats loose.
Good luck.
Joe
