Recently there has been a scraping noise coming from my rear passenger wheel. It started for a while but then stopped for about a week but now it is making the noise again. It doesn't sound like a wheel bearing noise, it's more of a high pitch scraping noise than a gridning sound. It also only seems to do it after the car warms up so after I drive it for like 10 minutes the sound comes and it seems to go away when I am turning right. It does smell a little like something is burning when I get out of the car but for some reason the smell seems to be stronger from the driver rear wheel not the passenger.
I haven't gotten a chance to take the wheel off yet and check anything. But I drove the car for a while so it would make the noise then I jacked it up and turned the wheels but no noise from the rear. But I pulled the parking brake up and tried to spin the wheels the driver side rear would just move a little and stop but the passenger side would make a scraping noise like the one heard when driving.
Any ideas of what I should check when I get the wheel off? Thanks in advance.

 

Check how much meat is left on your brake pads. It might be time for a brake job.

 

bump

 

have you at least taken the wheel off? do that and spin the rotor you will be able to see brake pads and look for groves on rotor and feel if the wheel bearing is bad when you spin it. otherwise take it to shop. you are not giving much info to go on nor any trouble shooting steps you did.

 

I took the wheel off and the spun the rotor and the wheel bearing didn't feel bad. I didn't check for grooves though I'll check that tomorrow. It also doesn't make noise when I am going in reverse no matter how fast I'm going. and the noise disappears when I am accelerating but as soon as I come off the gas it comes back.

 

check the hub nut/axle nut?

 

if it's this:


then bend your rotor dust shields back some

 

Okay so I checked the rotor there are no groozes in it. I tried tightening the axle nut and I only got it to turn maybe 10 degrees so not much at all. It kind of sounds like this video just a little nastier not so smooth sounding.

 

Have you checked the brake pads ? Next is rotor dust shield , then bearing. Also it is possible that something came loose in the e brake assembly

 

Break pads are still good. I didn't really check the dust shield too closely because it didn't look like it was touching but I'll double check that. It is weird that the noise only happens when the car warms up.

 

While driving, does the sound change when you gently apply the brakes or pull the parking brake?

 

It gets louder when I press the foot break, but that may be because it also gets louder when I am slowing down. But if I tug at the parking break the sound doesn't change even if I hold it up for a short while.

 

Brake pads or wheel bearing can cause that. Did you look at the inside pad?

 

I have been super busy so I will check the inner pad tomorrow when I get back from school.

There is now a big groove in my rotor! It was not there yesterday and just appeared today! What would cause this? It is definitely the same thing that is causing my noise.

 

Cheap brake pads can have impurities in them that cause grinding / squealing sounds similar to the end of pad life sound. Can also cause damage to rotors.

 

I just got a used 350z for cheap and i have this issue but louder. i'm on 2006 infiniti g35 19 inch rims. right rear. goes away turning right. happens after i drive 20 feet. at first the rims was very shaky and axle nuts was loose. the sound got worse after trying to see what it is. could it be offset or wrong lug nuts? or im thinking frame or shocks. i thought it was dust plate. rotor brakes ect. but checked all that already.
