I'm leaning toward the alignment being off.....

A good way to tell if its your alignment's fault, in dry weather when you go over a bump in the road, with 1 or the other rear wheel, do you get a shimmy from the rear end of your car til both rear wheels have even weight loads on them/are flat on the ground again?

If so then your Toe isnt up to spec anymore, you'll need an alignment
