Front CROSSMEMBER Removal/Installation [(Us)]: Notes

CAUTION:

• If the front ABS wheel-speed sensor wiring harness is pulled by mistake when performing this procedure, it could cause open circuit. 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 and linkage are disconnected, the internal parts of the clock spring could be damaged. After disconnecting the steering shaft, secure the steering wheel using tape or cable to prevent it from rotating.
• Do not allow the dust boot of the front stabilizer control link to touch the body, the front shock absorber and coil spring, and the hand tool. Otherwise, the dust boot of the front stabilizer control link could be damaged.
