Parking assist sensor in front left bumper replacement

It's easier if you have a lift or jack it up. Make sure you use a jack stand on the frame for safety. Then remove the rubber splash shield if equipped. Just remove the rubber grommets and push it out of your way to gain access to the inner bumper. The sensor is held on by one of two ways. Either has a clip and push up to release it or a bolt that you remove to release it. Then just pull it out pushed a new one than re-secure it.
