Guys since I bought my car ( which one front ended) I've been experiencing vibrations and problems with the steering, today I realized that the front radius rod has the form of a semi circle, I was wondering what could cause this problem, could this cause vibration?

Need help here, what should I do? What does it cause?

For those who dont know what the front radius is.

Get new radius rods since yours are obviously bent. If they finally break in half you will probably lose control of your car and crash it. Get it fixed.
