Vibration after alignment

So I had my front CA bushings replaced (all of them), and I was advised to do the alignment, which I did. It was OK, aside from the steering wheel that was a bit to the driver's side when going straight, so the shop adjusted that. All well, except that I get vibrations on 80 and 120 kmh (at 50 and at 75 MPH), which I know are said to be the speeds where vibrations will be felt by the driver (something about vibrations amplyfiing at those speeds). Whatever. I want it fixed, of course, although it's not some serious vibrations - but I feel them.

So what do I do? Get alignment again? Or try to see if tires are balanced first (though balanced or not, they did not vibrate before alignment & CA bushings)

maybe the shop didn't tighten the control arm bolts fully? Could also be that, other bushings are on the way out such as the track bar, sway bar/links, or the tie rod end joints. Always good to get a balance when you get an alignment though, just to be sure!

check your front pinion angle after the new bushings, sounds like the pinion u joint giving you vibes, slight angle changes can do this on old worn or slightly worn u joints
