1996 Chevy Monte Carlo front end clunking noise when hittii

I had just replaced my front end struts due to a clunking constant noise in ftont end especially when I hit a bmps it is loud I put on th new struts and the car is still doing the same problem it is on both sides should I have replaced the springs also or maty there be anotherproblem. The steering is fine makes no noise when I turn or when the car is on the expresssway about 65 mph there is no noise. Any thing I should check 4 would be great
