Question: Why is my car shaking bad in the front?

Once I reach approx. 40 mph my car shakes really bad in the front. It seems to not be as noticeable once I reach approx. 50-55 mph. My son owns a small auto garage business and he has replaced the entire driver side cv shaft, changed both hub bearings, rotated & balanced tires and had it aligned...and it still shakes! He is lost at what it could be. We are hoping maybe you might have an idea what else might be causing it.

Worn suspension components, or a problem with the transmission could also a source of the shaking.

Try running it on the lift at the speed of the vibration, this might help locate the problem.
