Thread: Scraping noise at low speeds.

Could be that you have something rubbing on your rotor. Like the little bracket that holds the ABS sensor connector. I've done that before.

Or it is a possibility that the calipers are not retracting all the way and you have a pad or one of the metal clips rubbing lightly on the rotor.

Try to jack up that side and spin the tire by hand to isolate where the noise is coming from.

I would check the play in your wheel bearings then. I had an issue where I had a wheel bearing go bad. It didn't groan or throw any ABS lights. But I heard a scraping noise from the drivers side. Pulled the wheel to find the wheel was grinding on the strut because the wheel bearing was bad and allowing the wheel to tilt in.

So check your bearings.

Sounds like the wheel bearing again. Did you change it yet from the last post? Did you try loading the bearing test I recommended? I doubt this, but check the inside of your rim and the strut for rub marks. When did this noise start to appear?

The only thing I can think of is if the tensioner was somehow lose, and the chain was rubbing on the block or something. But even still, I get no noise when the car is up on jacks, in drive.

You should see how much the chain that was on my Regal stretched. The tensioner was hardly doing anything anymore. Yeah it had 200k miles on it, but they do stretch.

So now it does it in park vs before only when driving? Please check the timing chain before something serious fails. At least have someone rev the car while you're checking for where the noise is coming from. The gaskets for the front aren't that much if it is the timing chain.

It might have always done it in park, I could just never really hear it I guess. I must have forgot to roll down the passenger window. I'll check the chain this weekend. Could the oil pump cause this?
