FRONT CONTROL ARM
The arm spans out to the spindle or knuckle support and is connected with a ball joint or a pin and bushing. In many applications a control arm works in unison with an upper or lower control arm. This is called a double wishbone suspension. Control arms typically house wearable suspension parts. The inner part of the control arm will attach to the frame by a shaft and or bushings. The outer end will have a replaceable ball joint or lower outer pin and bushing.
