Wheel loose, shaking when not turning

So here is an interesting one I just noticed...

I have some play in the wheel when the car is stopped, and when I'm on the freeway, going straight there is a lot of wobble but if I turn at all, it immediately goes away. Starts about 55-65mph

I don't think it's a wheel bearing since I've done a few on my LT and there is no grinding noise.

Here is a video of the wheel while stopped. (Turn volume up a bit)

Anything you guys recommend I inspect first?

It could be tie rod ends , loose input shaft to the steering rack, or the intermediate steering shaft.

When was that wheel last removed and reinstalled? May have been installed incorrectly....."out of plumb". Wheel weight knocked off? Lug nuts not tightened correctly? Easy stuff first !!!

This is a common symptom of something loose. When you're going straight there is no load and loose things can vibrate, As soon as you turn the wheel, everything is suddenly under load and the vibration stops.

I believe I've inspected the tie rod ends when I did some other work In that area recently and they checked out.

Where can I access the last 2 items?

If I swap front to back, would that eliminate the possibility? The front tires have some wear on the outside...same as my 2010 LT.

About a week ago when I did rotors/pads/control arm bushings/sway bar bushings and strut mounts. Lugs are 100% torqued correctly.

Makes sense. I am willing to check whatever is needed!

Where the LCA’s rear bolts torqued correctly, 74 ft lbs then 180 degrees tighter?
the steering shaft lives up under the dash above the pedals, the steering rack is on the subframe behind the engine

Get under there and look at it while someone does what you were doing and you should be able to find it.

The steering wheel wobbles while driving straight. I don't think she wants to be under the vehicle while it's being driven. I wouldn't recommend this course of action.
