Still struggling with steering issues

The vibration and sloppy steering is noticeably worse on rough roads, and seems to improve a bit on smoother pavement. The steering wheel shake gets worse on the freeway around 75 mph. I have also noticed that my driver-side side view mirror seems to vibrate while my passenger side one stays perfectly still. So far I have done the following:

So far I have done the following:
New tie rods (inner + outer)
New front drop links
New sway bar bushings (front + rear)
New control arms (front + rear)
New track arms
New trailing arms
New struts (Bilstein B4)
New strut mounts (front)
New tires (Conti ExtremeContact DW)
4 Wheel Alignment
Wheel balancing @ a reputable shop

I have done all of the work myself (except for the alignment, balancing, and tire mounting), but I’ve been to a few different specialist shops and no one has been able to fully solve the issue. The parts I replaced have improved on the issue, but the car still does not feel like it did before this issue arose. Anyone have any ideas? Could this be a bearing issue? I can't really find any play when pulling on the wheels nor is there a noticeable drone at highway speeds. Does the actual steering rack play a role in this?

Easiest thing for you to do is swap front wheels & tires to opposite side. If the vibratons change to the other side it's that wheel &/or tire. If no change it's L/F suspension.

Would it be impacted by the direction of my tires being swapped if I do this?

No, but if the tires are directional you should swap back to the proper side if the vibration doesn't change.

I swapped the wheels yesterday and the problem is still there. It feels like it's coming from the driver's side because my sideview mirror on that side shakes a lot (could be the mirror being loose, but it could indicate that side as well). Is it possible that the bearing is going out but it's not making any noise? Otherwise I don't know what else it could be if the wheels/tires are true and round. Could it be the rotors? Mine have a pretty big lip on them, but no marring.
