Those bolts are tight and look to be totally normal on mine.

This vibration is definitely felt thru the steering wheel. It noticable at 50 - 70 getting worse with speed. Then it smooths out a little bit at 80+ although still there slightly.

Is is possible that I've incorrectly focused on the drivers side because thats the side I see vibrating when on the rack? Could a tie rod or something on the OTHER side cause this?

I appreciate the help here.

Put your hands at 12 and 6 on each front wheel (on jackstands). Shake the tire in and out from that position. If it moves, it'* a hub/bearing assembly. Spin the tire (in neutral) to confirm. Grinding? Noise?

Put your hands at 3 and 9, and do the same. If it moves there, but NOT at 12/6, it'* a balljoint/tie-rod/rack issue. Or possibly control arm bushings.

If neither move as described above, be looking at tires/wheels/brakes.

No movement at 12/6 on either wheel. I do get the exact same slight movement on each wheel at 3/9. Not very much. I see the arm moving with each wheel too when I do.

Isn't a little bit of side to side movement normal? When both wheels move the same amount? Or no....?
