Spring, Coil, F-150

 CAUTION: The axle must be supported on the jack throughout spring removal and installation and must not be permitted to hang by the front brake hose (2078). If the length of the front brake hose is not sufficient to provide adequate clearance for removal and installation of the front coil spring (5310), the disc brake caliper (2B120) must be removed from the front wheel spindle (3105) according to the procedures specified in Section 06-03. After removal, the disc brake caliper must be placed on the frame or otherwise supported to prevent suspending the disc brake caliper from the front brake hose. These precautions are absolutely necessary to prevent serious damage to the tube portion of the caliper hose assembly.

Removal

1. Raise the front of the vehicle and place safety stands under the frame and a jack under the axle. Refer to Section 00-02 for hoisting instructions.

2. Remove the wheel and tire assembly. Refer to Section 04-04.
