Suspension - Front (2WD Coil): Description

Front suspension is a coil spring, twin "I" Beam-type. "I" beams are mounted to a frame pivot bracket at one end, and to the steering knuckle and a radius arm at the other. Forged axles are used on F250/350 and Van models. The F150 model may be equipped with either a stamped or forged front axle.

On forged axles, steering knuckle is mounted to the axle by a solid, constant diameter kingpin. Bronze bushings are pressed into steering knuckles to provide bearing surfaces for kingpin. On stamped axles, ball joints are used.

Radius arm runs rearward from axle to a bracket mounted on frame side rail. Coil spring is seated on top of radius arm and in a bracket mounted to frame. Hydraulic shock absorber is mounted between frame and radius arm to dampen road shock. A stabilizer bar is located in front of the axles.
