My 2014 1500 Silverado 4x4 has the same issue. The ABS kicks in at low speeds. The stabilitrac and abs lights are constantly on, and the annoying beeping sound activates when i hit a bump with the right front wheel. I removed the front wheel speed sensor and noticed it had metal shavings on the tip. I cleaned it and the issue was resolved. However, 3 weeks later i returned to square one. I believe the wheelhub assembly has gone bad. Does anyone know if this is covered under the powertrain warranty?
