Reading your post the first thing I thought of was front wheel bearings. But I agee with you as to the lower control arm bushings maybe a problem. You maybe able to determine whether it is the upper or lower shaft by loosening the unbolts on the lower shaft and levering the shaft off of the index rivet in the front saddle. With this done try to jack up the passenger side again and see if it makes a difference in it how jacks up with the lower shaft rotating free.
If that doesn't make a difference your upper shaft maybe gauled. If it acts like the drivers side now, the lower bushings maybe gauled.
Worst case both shafts are unhappy.
I just changed my front springs and lower control arms and your driver's side numbers sound about the same as I saw on both sides of my Burban.
When I installed the shafts in the arms I used ChevyMikes method in this thread. The second post.
Good luck.

As a second thought did you try your jack test with the shock disconnected? A bad shock could cause the same result.

PPS Here's a tire link that may help.
