Scraping sound - passenger rear wheel area

Hello all!

First time posting. I have a 2014 limited with about 80K miles. While driving a few days ago, it developed a scraping sound - almost like the dust shield was rubbing against the rotor. Varies with speed, definitely metallic in sound. interestingly, the sound changes slightly as I go over bumps in the road, and disappears entirely when I apply the brakes. Sound will also change slightly as I turn left or right. In reverse, the sound is much deeper, but not always present.

Based on those indicators, I was convinced that possible the parking brake shoe came apart, or the dust shield did in fact rust out somehow and was rubbing on the rotor.

- I've removed rear wheel - no signs of rubbing
- Rotor looks good - both on the main surface and the inside surface for the parking brake.
- pads look good. lots-o-meat on them.

I'm at a loss. Has anyone else experienced anything similar?

Thanks from a newbie here!

I had something similar when a shop excessively over torqued a wheel on my 07. Has anyone worked on it recently?

 

No, the last time the rear wheel was off was about 2 years ago when I did the rear brakes.

 

Hey guys!

I am experiencing the same thing right now! I can’t figure it out for the life of me. Seems to be when the wheel rotates under load. Checked for signs of a bad bearing and brakes. A shop mentioned something about the parking brake boot? Did anyone have any luck?

Thanks,

Troy

 

I’ve had rusted/dry caliper slide pins cause noises like a loose heatshield on my old Sienna. But that wasnt a scraping sound, more like metallic rattling on bumps.

 

Does the sound change if you sway back and forth while driving? Does is do it more or less in reverse? Have you raised or lowered the spare tire recently?
Reason for the questions, as it sounds like a brake pad squeeler is rubbing. Which is an indication your rear inner pad is below 25% and will be more noticable when you sway the car or drive in reverse.
Could also be a wheel bearing which you will hear change its pitch when you sway the car.

Other thing it the spare tire heat shield is known to rub/ vibrate against the exhaust if it gets bent just right. And its not hard to bend it either. Take a quick look, give it a tweek towards the spare tire just to be sure.

Good luck and keep us informed of what you find.
