I recently replaced a front hub - twice. Anyway, after putting the newest one one, I have noticed an intermittent problem with the ABS. Occasionally, the ABS will activate while rolling to a stop. Usually, the speed is less than 5 mph, dry pavement, gradual stop, low brake pedal pressure. I can feel the brake pedal vibrate and truck does not continue to slow at the same rate. I have tried to make it repeat, but cannot. This happens once every 3 or 4 days. The ABS indicator light does not stay on after startup.
Any ideas? I was under the impression that ABS 'turns off' at these low speeds. Is this more of a computer problem?
