WARNINGS: When installing the front wheel speed sensor, carefully align the hole in its housing with the threaded hole in the knuckle. Do not rotate the sensor around the longitudinal axis during installation.
The increase in resistance to the sensor movement should be felt only in the last 2 mm before it is fully seated in the knuckle. If the sensor enters the knuckle hole with great resistance from the very beginning of installation, remove the sensor and eliminate the cause of jamming (dirt, burrs on the body, etc.) It is strictly forbidden to press in the wheel speed sensor with a hammer.
