Front of my van makes noise when i hit a bump and does this thick vibrating ? on 2002 Ford Windstar

The vibrating is heavy and comes randomly while I'm driving any suggestions on what could be causing my problem?

Have tires and struts checked.depending on speed the symptom occurs at it could be either or both. Or I could be totally off-base.
Thank you I'll have to check into it I'm thinking something might be wrong with my electrical components I'm thinking one of my censers is failing.
Ziptie 12 is an idiot , of caorse it's electrical. I've never heard of 'thick vibrating' sound from suspension. Maybe the arcmeter diode trio is loose.
