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.
