Rear Magnetic Encoder: Inspection
WARNING: This page is about a different car, the 2021 Subaru Ascent. However, it is still accessible from the selected car via links, so may be relevant.
Visually check the rear magnetic encoder for any damage. If necessary, replace with a new rear hub unit bearing.
NOTE:
Because the magnetic encoder is integrated with hub unit bearing, replace the hub unit bearing with a new part if there is any defect found on the magnetic encoder.
