07 Yukon Denali rear swaying on highway

[JML07denali]

I have family in town so the truck is loaded with weight. (7 people) When I'm on the highway doing about 65 or 70 the rear sways side to side kind of like if you were on a boat. What could it possibly be. Shocks? Sway bar bushings? What could I do to diagnose the issue. I have no warning lights.Tires have about 70% tread and are balanced with no shakes. Has anyone experienced this before?

Shocks, if not sway bar end links and/or bushings or link bushings

Are your wheels torqued to spec?

Have you checked the sway bar bushings?

No, and how can I tell if they are good or bad?

are you sure the autoride shocks are working correctly
