Recently I have been hearing a grinding noise when driving the car around town, I started thinking it was my struts, but those are fine, now it sounds like a metal grinding noise, which happens when hitting small bumps or turning my wheel. Which leads me to think it is a bad wheel bearing set, bad brakes, or bad CV-joints. I am taking the car into my dealership tomorrow morning. I have had this car for a total of a week, and just started having issues with the car.
Do you
have the same problem?

Good evening.

If the noise changes pitch while you increase speed or decrease speed, good chance it is a hub bearing. Common failure.

If it only happens when turning then it is a CV joint in an axle shaft.

It just makes a weird grinding noise when driving, does not get louder when I speed up, just when I hit small bumps or turn.

Now it sounds like it is coming from the front left tire, but I really do not know.

Okay, another thing is that if I put my hand through the rim and touch part of the wheel bearing, it is extremely warm, it should only be warm, like its way too hot.

The brakes and the hub will heat up. You should not be able to touch it.

If it were overheated you would notice an issue with the brakes.

Temperatures run between 150-200 degrees when running for a period. When you stop, it heats up before it cools off.

So it is normal that between the rims is super hot? I know I may be asking dumb questions, but I just bought this car a week ago, and I do not want too many issues.

Yes it will be hot to the touch. You should not be touching when it is hot anyway. Even we have to use gloves at times to remove a wheel.

The grinding noise I am hearing is not a constant noise either, it I kind of random as well. Would that still be an axle?
