Why does ABS trigger after replacing an axle?

The anti-lock braking system activates inappropriately at low speeds and during braking because a wheel speed sensor tip was damaged or debris like rust and dirt interfered with the sensor during the axle replacement. This unexpected braking interference compromises normal vehicle stopping behavior.
