I have a 95 Z28, and a while back ago I hit a curb pretty hard on my front right side, and ever since then when I get up to 50mph or above and start to turn the wheel left it makes this whineing noise. This also causes the wheel to vibrate a little and cause this popping sound also that hits so hard I can feel it at my feet while I am driving, an allignment has been done recently and while my car seems to drive better I still have this noise coming from the front left side of the car. Does anyone know what this is? Any ideas would be helpful.

Thanks
