2004 Elantra vibration from the front end

Hi, my car makes a rolling/vibrating type noise when im driving. It gets louder when i go faster. This is true whenever I am going straight or turning left but if I turn my steering wheel even the slightest bit to the right, it goes completely quiet...

I just bought the car from a used car dealership which I now have a negative opion of. Anyways they had put new tires on the car before I bought it, which I am thinking was likely to either to solve or hide the problem with the vibration. The car didnt have the vibration problem when I first test drove it. The symtoms showed up after about a month of ocassional driving.

Thanks for any advice.

I have seen this quite a few times with the Elantra, it has engine vibration problems. Some stuff might have came a little loose on one side rather than the other, explaining the turning phenomenon. Make sure everything in the front of the car is tight, mainly the bumper and headlights. If they are loose just retighten them, and even consider upgrading to better quality bolts. Hope this helps.
