Thumping Sound While Driving

I have a 2002 grand caravan sport with a thumping sound coming from the front end of the van, but not while going over bumps. Mine is more like when I drive faster than 5mph. The faster I go the faster the thumping sounds.
I have replaced both front tires, 4 wheel alignment, new breaks and rotors, but the sound is still there. I'm out of places to look other than maybe the struts. Please advice if you've had this same issue and found a solution.

I'm going nuts, I have just replaced the front struts and ball joint on both sides and the thumping is still there. Please any one with a solution?

Swaybar bushings?

Finally found d problem. "wheel bearings" replaced the entire wheel bearing assembly on both sides and the van rides like new. It's an easy one hour labor job for both sides. FYI, amazon is a great place for cheap(low price) parts.

I had a very similar problem, more noticeable when going over bumps, or any vertical motion. It was a deep thumping sound. Turned out to be the swaybar bushings. They had cupped and made the sound as the bar rotated. It was a cheap fix, though it cost me more because the mechanic replaced the tie rods before finding the real problem.
