Might be noteworthy to add that the ABS/TCS lights almost always came on when turning the wheel sharply to the left. The lights rarely went off otherwise. I thought it HAD to be wiring harness problem where the harness was being pulled while turning, but using an ohmmeter to check out the harness from the hub assy to the ABS module checked OK, even while pulling on the harness and/or turning the wheels. Because the problem didn't occur until the wheels started spinning, checking it out while parked didn't do any good. If the steering didn't get obviously sloppy, I probably would still be looking for the problem, lol. After correcting the somewhat loose wheel hub bolt, I didn't realize that the two issues were related.
