Toyota Repair: dont know, toyota rav 4, 2005 toyota rav 4

Question
I have 2005 Toyota Rav 4.it has approx 19,000 miles on it .I recently had oil-change also. for last couple of days I noticed its making noise (kind of grinding )while driving at 30 mph and above .it does not make any sound at rest or lower speeds .

What could be the problem .please help me

Answer
I'm going to refer you to the toyota dealer for help on this because it is still covered under the factory warranty and if there is a problem it will be fixed at no charge to you, I can't speculate on what this noise may be without being able to hear it, so in this case you will need to trust the toyota dealer to diagnose and determine the cause of this noise.
