Car shakes violently to 20 mph then stops

Hi,

Yes, an axle or joint can cause it, but I would think you would hear noise when making turns such as a clicking. Also, I would feel you would notice it at any speed. Take a look through this link Here is one that deals and see if anything mirrors what you experience and let me know:

Here are a couple links dealing with CV joints/axles in general.

Is there any growling noises or noticeable sounds related that may indicate a wheel bearing? Also, do you feel it more in the steering wheel or the floor of the vehicle?

Let me know.
