Thank you sir! This was the fix. The bolts weren't loose just not at these torque specs. Torqued and it feels solid now

Same issue. I may have over tightened the bolts.

I too have noticed a similar feeling with my car after putting new rear tires on. My buddy says it's all in my head. I'm like no, Def something going on here and it wasn't like that before.
I notice similar, wiggle in the rear at high speeds as well as when taking corners aggressively, so much so it kinda scares me.
My first thought was the tires, but they are the same size as stock and are brand new. I figured they needed to break in a bit more. Kinda seems like the rear is tracking left and right. My buddy says it's probably the grooves on the road and the tires are new, I drive the same roads every day and it was never like the way it feels now.
I have had the rear up on Jack stands countless times. Is it possible the irs settled wrong when letting the car down? Could it be the bushing on the trailing arm?
Following along.... I want the car back to the way it felt befoe

New tires, are they the same width? I'm having the same "high wind feeling" since I changed my wheels to wider ones.

No. I went from 255 on rear to 315. Since torquing the bolts to spec all is fine now

I guess I should also check my torque specs. I didn't do the HS but did change control arms. Thanks for that.

Load the suspension when you do. I think that's where I went wrong.
