Thanks all for the responses. I went out in the garage and measured all four wheels from ground to the center bottom of wheel well before start (bs) and after start (as). I had a 3/4 tank of gas and no one in the car. Here are the results
RR bs 31.7/8" RR as 31.7/8" > no change
LR bs 31.9/16" LR as 31.9/16" > no change
RF bs 31.1/2" RF as 31.1/2" > no change
LF bs 31.1/2" LF as 31.1/2" > no change

I am not sure what this tells me but I would say the RR is quite different than the rest of them ie almost 3/8". I will check out the youtube mentioned in this thread. I suspect that both the alignment guy and the Indy shop would have suggested ball joints and bushings so my question still stands.

Has any one ever gone thru calibration of the self leveling? I know that it can be done but wouldn't the shop check ball joints and other suspension stuff before doing this calibration?

Thanks for all the input, I am gonna research as much as I can to try and get it right. From my untrained eye, there does not appear to be a lot of unusual wear on any of the suspension parts. I do a visual check each and every time I change wheels (twice a year) and look for cracks in the CV boots, worn bushings, leaks, worn brake pads, etc. Any thoughts are greatly appreciated. I still want to pursue the idea of calibrating the self leveling because it would be a lot less expensive fix. Thanks again in advance.
