You have a good point... I would have looked there next. I did end up fixing the problem. Here is what I found... 3 of the 4 tires were the correct size at 225/60R16 and the 4th was a 225/55R16. I replaced the incorrect tire and that fixed 75% of the issue, however the problem persisted under engine load while cornering. Replaced both rear wheel speed sensors as they were original and slightly out of spec. Did not need to replace the front two speed sensors as they had been replaced at one point in time and ohmed perfectly. I did however clean them. All in all it was a combination of two problems. Mismatched tires and worn/dirty speed sensors. Just thought I would post my findings. JNelson
