Good To Know

Q: How do I know if the front ABS sensor is failing? A: An illuminated ABS warning light, pulsating brake pedal under normal stopping, or traction control failure are common signs.

Q: Is it necessary to replace both front sensors at the same time? A: While not mandatory, replacing sensors in pairs ensures consistent electrical resistance across both sides of the axle.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
