^^ bingo...it's the endlinks. Replace them and you will be fine. I replaced mine after raising my Sonata back to stock height after being lowered.
It's a known fact in the Hyundai community that their endlinks wear VERY fast. If you have ever taken one apart, you will see why. The ball joint inside the rubber cover is not made very well.
Also, the endlinks are not bushings...its a rod connected to a ball joint on both ends that attaches to the strut and sway bar. It's the ball joint that fails. You can replace the sway bar bushings, but that really isn't the cause of your issue.
