HIT CURB, SLIGHT VIBRATION IN STEERING WH

2006 Lexus GS 300

Steering problem
2006 Lexus GS 300 6 cyl Four Wheel Drive Automatic 22,500 miles

I hit the right front wheel on a curb at 5-10mph causing a scrape to my rim while making a turn. Afterwards, I notice that the steering wheel was vibrating slightly by feeling it but I could not see it vibrate. So, I got the right front wheel rebalanced and got all 4 of my wheels rotated and rebalanced. This resulted in the rim and tire that I hit to be placed in the rear on left side. I still felt vibration, but it was not as bad as before. I also noticed my car was pulling left or right on uneven road, so I got the 4 wheel alignment, and now it is fine. However, I still get slight vibration through my steering wheel and floor at times when driving on certain roads ranging from highways at 70-80 mph to city roads at 45-55mph. It is so minor but its still there. I told my Lexus dealer about this and the mechanic took the car out with me to duplicate the problem, but he couldn't since the it comes on certain roads and doesn't on other roads. It never used to do this. Sometimes it there the whole time on a certain highway or comes and goes. Mechanic told me it may be due to one of the tire being cupping but I told him it can't be since I felt it after I hit the curb and the the wheel I hit is now in the rear, so the problem has to be located in the right front region. Do you think it may be a more deeper problem? Such as wheel bearing damage, control arm, etc? I am not sure what to do next, since the dealer says everything is fine, but I doubt they even looked at the components of the right front wheel.

If it does it on certain roads, I would lean towards a strut problem or maybe a lower ball joint bent. Sounds like the tires were cross-rotated, personally I never do this, straight forward and back for me. Have them do that and see if the pull goes away.

Thanks for replying,

The tires were first rotated by placing the 2 front tires to the back and the back tires were cross-rotated to the front, but the vibration was there and the steering was a bit leaning to the right side after this, so I had them switch the tires to the opposite side and the car went straight now.

As you mentioned about the ball joint and strut problem, are they common to be damaged on curbing a car? How about a wheel bearing? I don't hear any noise but I feel some kind of coarse feel coming through the steering wheel at times even on the smoothest tarmac or cement road that I always drive on every day. I am so positive that it isn't anything to do with the tires, since the its coming from the front even after doing the rotation. Let me know, and I will head to my dealership soon to have them really inspect the car, since last time they told me that the car drives as it is, and it doesn't.

Yes it could have damaged the wheel bearing as well. HAve it looked at before something fails causing more damage

Can a wheel bearing cause slight coarse vibration through the steering wheel and not make any humming noise and not increase noise when turning heavily on a highway? I have not noticed any noise from the bearing while driving.
