1994 Plymouth Grand Voyager

I have a 94 Grand Voyager with 82,000 miles, whenever I go over a bump a lould banging sound from the front end or suspension. It is so lould it feels like the tires are going to blow. Almost like the front shocks are not working. It scares me every time I hit a bump & I know this is not normal. Can someone please help me? Otherwise the car is like new. I have had the entire front end checked & knowbody can tell me what is wrong.[size=18:21688a62ab][/size:21688a62ab][size=12:21688a62ab][/size :21688a62ab]
