What to do? (Dealership/tire balancing)

So I rotated them today and the issue went away. I did the left side first and it got a lot better. One tire was at 31 psi, and one was at 37. Normalized them both to the proper 32psi. Test drive, it was noticeably better. Not perfect, but better. Then rotated the right side. Checked pressure, 25 and 33 psi. I'm pretty sure the 25 and 37psi tires were the ones on the front, and that was probably contributing somehow. Anyway, test drive revealed it was perfect now. Not at a shake at all up to 85mph. So I'll give them half a point on the balance issue. But minus 100 points for over inflating 1 tire and taking the air out of another. Also, minus another 100 points for torquing the lugs to somewhere north of 200ftlbs instead of the proper 90ftlbs. I had my torque wrench set to 150ftlbs to remove them and it just clicked away. Reversed it to tighten, clickyclicky, and went all the way up to about 175ftlbs just to see what it would take to move them. Not even budging. I'm no weakling, but they had me beat on an 18" torque wrench. Pulled out the 2ft breaker bar and a few of them were so tight I was honestly worried I might shear the pin on the bar or break off a atud. I've taken loose D60 pinion bolts that weren't that tight. Thank goodness I discovered this at my shop instead of trying to change a flat tire on the side of the road.

I Know they were Taught a certain way, but always hated when getting an alignment, & the Expert pumps the tires up to 32psi! Once their done, I air them back to where they Wear properly! Now, considering what you found with your shop, will you go to them in the future? I Sure wouldn't! And How many Horror stories do we all hear, about lug nuts being run up to 150-200#, &/ Or Cross threaded? Gee, my stud broke off! Wonder why?

that there are weights 180° from one another says they didn’t remove the old weights before they tried to rebalance, and probably just tossed the wheel up in the balancer with little regard to fit up. (rework attitude)

it is possible you have a belt in a tire letting go which would throw off balance randomly as it’s moving around while spinning.

Yep. You should have weights only in one place on each side of the rim if they did the hammer on kind. Not in multiple places. That's someone who doesn't know how to balance tires if they did that.
