The front part of my car vibrates pretty loud at higher speeds. It's fairly quiet at low speeds, though. I just got a wheel alignment and that doesn't seem to be the problem and I've even rotated my tires. I've got the ball joint in the front to correct the camber. By the way, I've got Yokohama Paradas Spec-2 and it still grips exceptionally. The tread still looks good. I'm not sure what the problem is. It seems like the vibrations are coming from the left side of my car near the wheels. Do you think it could be an axle because I just replaced them about 3 1/2 months ago. Oh yeah, I have an ls-turbo. Any insight and words of wisdom is greatly appreciated. Thank you.
