If the lines are more than 1,59mm [1/16 inch] out of alignment, replace the damper. Inspect the rubber member for deterioration. If pieces of rubber are missing or if the elastic member is more than 3.18mm [1/8 inch] below the metal surface, replace the damper. NOTE: Also look for forward movement of the damper ring on the hub. Replace the damper if any movement is detected.
