Just got new shocks, brake rotors, bearings done. 2 new rear tires. front tires (old but good)were from rear. My vehicle sways at 55 + mph on highway on a straight away. Vehicle is not fully loaded with tools or equipment (carpenter). Had shops check suspension and steering, found nothing. Is there anything else that can cause swaying problem? tires? 2new 2 old. Any help appreciated. Thank you.

Have it aligned, excessive toe/camber can cause this problem.

i took it to pepboys for the alignment , the first time around. they said that the van didn't need one. Rather a tire rotation only. I'm just trying to avoid going in and out of a shop and not having the problem fixed. Need the vehicle for work, trying to avoid as much down time as possible. Many thanks.

Somnething is loose, it should not sway as you describe.

Steering, front suspension, bushings.

And I would find a good alignment shop, PepBoys, would not be one of them.
