1993 Honda Accord Suspension problem?

Hi

My car has noise at the front wheels when I turned.
I brought it to the car repair place and they replace both of the front axles. Noise is gone. However, when I am on freeway at 65-70 MPH with a little of bumps (normal bumps) on freeway, the car shakes a lot. I dont have this problem before replacing the axles. Can someone help me understand the problem?

Thanks
