front end noise

my inlaws have a 03 AZTEC that makes a random clunk in the front when driving straight and doing 70mph.has new struts on the front and it was aligned.it is a front wheel drive .any help ?thanks

Control arm bushings are bad. Thats why you are getting the clunk noise. My wifes car had same problem. They are $15.00 a piece, but also alot of labor involved.
