Mitsubishi ASX 4 rear wheel speed sensor ABS sensor holder ring. These rings do not come separately from the bearing assembly and quite often fail, meaning a full bearing replacement is required. This sensor holder eliminates the need to replace the entire bearing which can be costly and time consuming. This holder is 3D printed (my design) from tough, durable material. It is designed to push into place and secure the sensor in place. Note cleaning of the surface of the bearing will be required. Although the ring will fit tightly, it is advisable to glue/silicone it in place for peice of mind. The same can be said for the sensor itself. This may also fit other Mitsubishi vehicles. Sensor not included.
