Front CROSSMEMBER Removal/Installation

WARNING: This page is about a different car, the 2016 Mazda MX-5 Miata. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
  • Performing the following procedures could cause an open circuit in the front ABS wheel-speed sensor wiring harness if it is pulled by mistake. Before servicing, disconnect the front ABS wheel-speed sensor and set it aside so that the wiring harness will not be pulled by mistake.
  • If the steering wheel rotates after the steering shaft and the steering gear are disconnected, the internal parts of the clock spring could be damaged. Secure the steering wheel using tape or a cable to prevent the steering shaft from rotating after disconnecting the steering shaft.
  • If the steering gear is dropped it could result in internal damage to the EPS CM, therefore be careful not to drop it. If the steering gear receives an impact, replace the EPS CM.
