I noticed recently that i'm getting some vibration from the front end when I hit 70 or above. The steering wheels basically starts shaking. I had new wheels put on about a month or two ago, but they were balanced before being mounted. I also had eibach pro kit springs installed about three months ago. I didn't replace the struts, only the springs. I could feel that I need an alignment...i guess it's due to the springs now really being settled in. Could the need of an alignment be causing this? Do I need to get the wheels re-balanced again? Any other things I should have checked? Thanks in advance for any input.
