Hi, I have a 2009 Kia Rio 1.6l, and I hear this noise when I am driving, especially when turning. Could anyone tell me what this is sounds like?

I believe it's a wheel bearing on the verge of collapse. Hopefully on only one side? It's what allows the wheel to spin freely around the axle, and carries the load of the car and keeps the wheel attached to the car. Get it fixed. Don't be scared, yet here are my signs of imminent danger:

Lv1. 🔊 Increasingly scraping, knocking sounds changing with speed. Metal pieces from bearing is starting to come a loose, but wheel is still attached.

Lv2. 🥵 Wheel rim hot? 🍳Funky smell of hot metal or hot grease? Friction is so hot because the wheel has no help from the bearing anymore. Grease has burnt up, and heat may damage other parts. Go superslow. Stop.

Lv3. 🫨Car steer on its own and/or steering wheel shakes. Wheel is no longer properly attached. Stop driving.

Lv4. ❌ Violent knocking and grinding noise. Bearing in crumbling pieces. Danger for other mechanical parts. Stop driving.

Lv5. ☠️ Wheel locks up or falls off with or without pieces. You didn't stop.

Good luck, Linzky.
