Ok, now I get to say it: Where does the owner''s manual say to jack it up?
I would never try to run this test on jacks, put jack stands under the rear axle.
Also, I would try spinning the tires by hand before I cranked the engine. May discover the issue without risking injury or damage. Also there are precautions to consider as spinning the tires like this can result in tires spinning faster than design and result in tire coming apart.
You had an issue with rattle from truck, especially when towing. Have you tried removing the hitch from the receiver? My hitch rattles a lot when I just have it in the receiver. I can't drive with it cuz rattle drives me crazy.
