What should not be done to ABS speed sensors and sensor rings during installation?

Clean with high-pressure air
Hammer or tap on them
Lubricate with brake grease
Test with a multimeter

The correct answer is: Hammer or tap on them

During the installation of ABS speed sensors and sensor rings, it is crucial to avoid hammering or tapping on them. This is because ABS sensors and their associated rings are precision components that can be damaged by excessive force. The sensor rings, often made of magnetized materials, can be misaligned or even cracked if subjected to impact, which would compromise their functionality and the accuracy of the ABS. Additionally, improper installation practices could lead to issues such as erroneous wheel speed readings, which ultimately affects the vehicle's stability and braking performance. In general, handling these components with care ensures they function correctly, so adherence to proper installation techniques is essential. Cleaning with high-pressure air is generally acceptable to remove debris, testing with a multimeter is important to confirm that the sensors are functioning, and applying brake grease in specific areas as needed can help in maintaining proper operation—none of these actions compromise the structural integrity of the components like hammering would.
