147k steering wheel vibration at highway speeds

What is your question?

2012 regular Toyota Prius 147k steering wheel vibrates at highway speeds but only while steering slightly left(just a hair). Otherwise steers fine. Also, when I brake if someone cuts me off or traffic slows; going from 80 down to 70. It’s getting worse. The wheels get rotated and balanced every oil change 5k. They are all wearing normally nothing unusual. The alignment was done at the body shop because a guy hit me a month ago. All the brakes are good and wore out even. The rotors and pads were done end of last year. The front strut assemblies were installed after the body shop and the ride comfort improved but the steering wheel vibration is still there. I was reading possibly the wheel bearing but not sure. Also, today I noticed the vibration is mainly on the driver's side because my girlfriend, on the passenger side, said she only heard it on my side. Any suggestions or help? Thanks

What makes this problem better or worse?

Braking abruptly and some slopes on the highway
