Spring, Coil, F-150 and Bronco

Removal

1.  CAUTION: The axle must be supported on the jack throughout spring removal and installation, and must not 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 spindle 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 caliper hose. These precautions are absolutely necessary to prevent serious damage to the tube portion of the front brake hose assembly.

   Raise the vehicle on a twin-post (axle contact type) hoist. If a frame hoist is used, raise the vehicle and position tall jack stands under the front axle. Lower the hoist until the axle is in the normal ride height position.

2. Remove the front shock absorber-to-lower bracket attaching bolt and nut.

3. For vehicles equipped with quad shocks, remove the attaching nut and front shock lower mount from the stud on the bracket.

4. Remove front coil spring lower retainer attaching nut from inside of the spring coil.

5. Remove front coil spring upper retainer attaching screw and upper retainer.

6. Position safety stands under the frame side rails and lower the axle enough to relieve tension from the front coil spring. If a frame hoist is used, slowly lower the hoist enough to relieve tension on the front coil springs.

7. Remove the front coil spring lower retainer and the front coil spring.
