Mazda: Rattle, rattle

Some 2010-2012 Mazda3 vehicles (except Mazdaspeed3) may exhibit a rattle noise from the rear stabilizer when driving over a road bump. The noise may be caused by a loose rear stabilizer control link.

  1. Verify the customer concern.
  2. Verify that the rear stabilizer control link nut torque is at maximum specification (44.8 ft.-lbs).
  3. If loose, replace with new nuts. After removing the nuts, inspect the threads of the bolts. If wear exists, replace the control link. A new style locking nut is now recommended, available as part number 9YB0-41-031. The new style nut features two identification dots, and the torque specification with the new style nut has changed to 33-2 – 40.6 ft.-lbs.

A new style locking nut is now available. Note the old style nut (D) and the new style nut (E). The new nut features identification dots. The old style nut torque specification is 31.8 – 44.8 ft.-lbs; while the new nut is tightened to 33.2 – 40.6 f.t-lbs.
