Thanks for your inputl The tone wheel seems fine and the calipers don't seem to be bad
I am wondering if the problem is not the ABS system - the ABS light doesn't come on when it activates on a curve. However, the Vehicle Stability Control (VSC) light and buzzer do active. When the VSC light comes on, could this cause the ABS to activate on the effected wheel? You can feel the ABS activate on the outside front wheel when turning. In other words, the left front wheel ABS activates when turning a hard right.
Thanks for any thoughts you have.
