Road vibration/judder gone!

I was due for a tire rotation and took my car to a local town fair tire. When my friend drove my car last night, he told me to get an alignment done too since the car was vibrating at high speeds.

It seems that after tire rotation, wheel balancing and wheel alignment. Car feels a lot different, it runs more smoothly and it's more agile in corners.

Here is the print out from the before and after:

I got humming sounds at 58-62 only... no vibrations though. Usually I was told a bad alignment is responsible for car drifting to left or right while driving on flat land... not humming or vibrations. So, my guess is ur balancing took the vibrations away.

Can someone verify that alignments don't usually cause vibrations?

I did get an alignment, but the dealer didn't give me any fancy print out like yours, so there's no way for me to know if they actually did anything...

Replaced both front wheel bearings, still no use. Next step is to have the dealer raise car on a lift, bring the speed to 62, and look under the car for the source of the humming..... and I guess ill have them check alignment too

If your tires get louder when you are coming to a stop, then it's your tires "feathering"

Yea, I was told that when they balance the wheel they can see if your rim is bent or your tires need to be rotated. To balance the car, they usually put bad tires in the rear. I also noticed they installed new stick on wheel weights for balancing. So far, I am happy with the overall results of the car and def worth the cost of enjoying the smoother ride.

My guess is that it's your tires. Not all tires are quiet, especially after they've gotten some wear on them.

I'm currently dealing with something similar to this, only I don't know how to diagnose it. I'm thinking I could have a bent rim, or maybe my tire(s) need to be balanced/rotated. When accelerating/decelerating, I hear a loud flapping noise. I definitely know it has something to do with the wheels. I've checked under the car to make sure none of the linings are hanging or anything of that nature.

Anyone dealt with this before?

What tires were you using before and what tires did you replace them with?

My car has the same problem. If it becomes more common Infiniti will have to do a recall. I hear excessive road noise from the front left tire when driving over 50km/h. We should start a poll including all G owners to find out who else has this problem.
