I THINK THE PROBLEM HAS BEEN SOLVED!!! Thanks for all who helped.

I just got back from the shop and he found a poorly lubricated caliper pin on the front right tire, causing it to stick. On top of this, the ABS sensor was totally caked up with greasy dirty crud. I'm sure both were the culprit.

Even more, it was shown to me that the bushings in the rear where the trailing arm connects to the chassis is deteriorated and RIPPING on both sides. They will be replaced with beefier OEM replacements. (I decided not to go with urethane for my own reasons.)

BTW, he estimates a 5 hour job (and about $750) to replace those two bad bushings in the rear. I know it's labor intensive to remove all that stuff, cleanout the old bushing, press in the new one, and reassemble, but 5 hours for a professional? For the most part, this is a trusted mechanic by me and several friends. On the other hand, he didn't charge anything for today to diagnose the problems, regrease all 4 caliper pins, and clean the ABS sensor of gunk.
