1996 Jeep Cherokee front end shakes when I hit a bump

When I go over 40 mph and hit a bump, sometimes my front end shakes back and forth so bad I have to come to a complete stop to get it to stop. It is not a bounce but a strong vibration and shake. Feel like the front end will fall off. With a regular car (not 4 wheel drive) it feels like ball joints but does my jeep have the same front end arrangement?
