I would thake off both rotors and clean the rust from the area where the rotor meets the mounting flange. There could be some rust there which makes the rotor cock at an angle. When the car is jacked up I would also check my wheel bearings for play. The tire should not have any movement when you try to rock it in and out.

^^its not a problem in all cars. usually the problem is with the wheel bearings but if not then you have broken suspention/steering componets

Does the shimmy happen on both front wheels? If not, I would switch wheels and see if the side changes. Then I would switch rotors and do the same. If nothing changes you have a bad strut.

Get the tires ROADFORCED with a Hunter wheel balancer. It is common on Hyundai's to have shimmy if the balance is not exact. You should have no more than 5 pounds of road force on the wheel/tires.

Hyundai's are designed so the tolerances are very close and NVH is a common compaint and the Hunter roadforce balancer, which is in some shops but not all, can pinpoint wheel vibration where other balancers will not recognize it.

Alignment and tire pressure is not going to be that noticeable, unless it is severely out of spec, and even then, it can be out of spec and still be smooth.

If this shimmy is a new problem, I would suspect dented rims ( check the insides also ) or out of round tires, it could be a factory defect. A long panic stop could also flat spot them. If you are in the habit of taking speed bumps at 30 mph ( like I was ) you could have dented all of the rims. Alloy rims are not very durable.

today i found ashop which had the hunter roadforce balancer i asked the man
about roadforce but he knows nothing about this he told me that it is normal balancer he will put the tyre to read and no more is there any steps to use the road force system on this balancer or only a system inside it ,ex like cars with 16 valve

the rims are 100% fine ,look man me and my brother have the same car and both of us have this shimmy after rebalancing the tires(in diff places)
i think it is very rear to have a defect in the oem rims
it may be found in chinnese rims (i bought a set of rims five years ago in my mitsu lancer and there are alot of shimmy and after a lot search we found that the dimmention is 4/99 instead of 4/100 )

The guy you talked to is not informed on the NHV on the Hyundai. There is a entire 2 day class on the subject for dealer techs, and I do have the class manual and looked over it..

Most of the vibration at certain speeds is caused by improper wheel/tire balancing and out of round wheels/tires. If there is any wobble on the wheel, the chassis will pick it up.
