WARNING: This page is about a different car, the 2014 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
  • Verify that the rear crossmember is securely supported by a jack. If the rear crossmember falls off, it can cause serious injury or death, and damage to the vehicle.

Before performing the following procedures, disconnect the rear ABS wheel-speed sensor (axle side) and fix it to an appropriate place where the sensor will not be pulled by mistake while servicing the vehicle.
NOTE:
  • Mark the position before removing the rear upper arm.
  • Align the rear crossmember and rear upper arm markings when installing the rear upper arm.
  • Tighten the rear upper arm inner bolt completely before installing the rear crossmember component to the vehicle.
