Strange vibration noise (2001 i30)

[rubs]

Hi,

For last few days i can hear and feel a strange noise coming from car/engine when driving on city road between 25-40MPH but don't hear any noise when idle or driving on highway. What can be the possible reason for this noise?

Thanks

Not exactly sure but i own a 92 maxima but i had that same problem with my car and come to find out that the power steering pump was going out and had to replace it personnally.

Could also be tire balance. Sounds your going through a harmonic range pulsation. A certian speed where something vibrates. Have you had to skid latley? (leaving a flat spot on a tire, nearly impossible to see) Are your tires older? Could also be brake discs are a little warped.
