I can't say I have ever heard of a shock ever causing vibration at different speeds. Vibrations are caused by many things
 but in an automobile it is caused by parts that rotate. Have you determined that it most definitely is coming from the front? Have the wheels been balanced lately? How many miles are on the car? Have you ever inspected the driveshaft flex disc? If the vibration starts at a certain speed and stays then the first thing I would look at would be the driveshaft and flex discs.

You didn't report if you fixed both sides, or replaced the conical rubber bushings on the lower control arm, which requires the spring to be removed. Did you get an alignment? Did you replace all the bushings? Did you replace the ball joints and the upper control arm?
You didn't say how many miles but if they are over 100 - 150K, everything needs to be replaced, and an alignment done. The vibration could be tire wear and or cupping.
