Has anyone experienced a high pitched while while driving their jeep? Mine is a 2015 Wrangler Unlimited Sahara with 28k miles on it. It only does it in between 30 and 38 MPH. I just put new tires on it, but it was doing this before so I can rule that out. It sounds like a harmonic whine and not a squeal or something like metal to metal. Any help would be appreciated, this may be normal for jeeps as this is my first. I just want to make sure its ok, because it is fairly loud.
