Damaged wheel bearings can indeed affect the functionality of the ABS system, especially in modern vehicles which commonly adopt an integrated wheel speed sensor design. When bearing wear causes the axial clearance to exceed 0.05mm, it will interfere with the sensor's ability to read wheel speed signals, potentially triggering the ABS warning light. Specific manifestations include rhythmic abnormal noises during acceleration and high-frequency steering wheel vibrations within the 60-80km/h range. When noticing abnormal sounds or ABS warnings, owners can conduct preliminary checks: jack up the vehicle and check for excessive axial play (over 1mm) or grinding noises during wheel rotation, which indicate immediate repair needs. Professional servicing requires OBD diagnostics, with bearing assembly replacement costs ranging approximately 800-2,500 ringgit (including wheel alignment). Regular bearing inspections prevent sudden failures, while using specification-compliant lubricants and preventing water ingress can significantly extend bearing lifespan.
