Scratching noise when rotating wheel on jack stands

Sounds like pads on rotors to me.
Some slight drag is normal.
Can you confirm the spring clips are installed on the pads? The ones that keep the pads pulled away from rotor

 

The rear wheels will make a bit of sound when rotated, that's normal for disc brakes. Drag should be minimal, but the wheel will not be completely free spinning. If the rear brakes were reassembled with the inner pad pin not properly seated between the caliper piston spokes there will be bad drag. But I get the feeling that's not your problem.

From your earlier posts, it seems like you've got a front wheel bearing that's starting to deteriorate. Again, just guessing, that's probably the only problem. Likely other than that your front wheels/brakes are ok. Again, disc brakes are slightly noisy.

I've got a feeling you've got wheelitis, lol. I've been there: the closer you look at them, the more you start hearing/seeing problems, that are actually just the normal characteristics.

In your shoes, I would invest a few $100's to get a thorough 4 wheel brake and bearing inspections. Dealership would likely be best, or an independent Prius shop if there is one in your area. Working on Prius brakes requires some extra care: the safest bet is to disconnect the 12 volt battery at the outset, and before reconnecting pump the brake pedal several times to build up pressure. Also, it's critical to align (aforementioned) rear brake caliper pistons correctly with inner pad pin, to avoid grief down the road.

 

the springs are on top of the brake pads/
there are little holes in the caliber where they hook in.
if your wheel is off, just look for something that looks like two little wires (NOT like cables!) on top of the brake pads /

edit: yep, I guess the best choice would be what Mendel is suggesting: let it get checked by a dealer /
better safe than sorry /

 

I don't know, sounds normal to me. -ANY- disk brake will make a "scratching noise" when you rotate the wheel. A wheel bearing not already destroyed will usually not make any noise when there is no weight on the wheel.
If you can hear something when driving, particularly if the sound is heard when turning one way but not the other, that is often a wheel bearing. A 2014 should have no bearing problems, but I suppose they can fail anytime.

 

There yah go, I'd jump on that!

 

But if they find nothing and the bearings are ok they might want shop rates to cover the check.

 

In BC, Canad, initial diagnosis is usually around $75. Hopefully no more. Wouldn't hurt to ask.

 

I'm trying to figure out if my 2010 with 82k miles has a bad wheel bearing. I just rotated the tires and I hand-spun the wheels while up on the jacks. The sound that I notice is one like individual bearing balls making a clicking sound when they move into a new location as the wheel turns. Kinda like the sound of marbles hitting each other; very faint sound, but distinct on the wheel that I believe has the bad bearing. The "non-clicking" wheels do make a continuous soft "scratching" sound as the wheel spins.

I guess I'll have a dealer look at it, as I'm no expert and don't have the tools/time to do the repair myself. I may buy the bearing online and bring it to the dealer for install if I can save some money. As an example, from here:

First thing you need to do is stop hijacking Mr Nicolas's thread. Doesn't take anymore time than this post here to start a new thread. Then you'll have your own thread and it won't be stuck on the end of someone's else's thread.

 

In my experience- with several cars, a worn hub is indicated by the sound being heard in the cabin of the car while driving.
Also - when turning the car a certain way to ADD pressure to wheel, sound will worsen. If doing the opposite, removing pressure from wheel, sound goes away. Also - Sound changes with vehicle speed.
This, coupled with marked MPG loss.

 

The rears that just have pads should not make any noise when spun and e brake off. The fronts are more involved sine they are the drivetrain and you may hear slight noise from the pads rubbing.Real easy to check for warped rotor. Get going fast ans then apply the brakes firmly.
If you hear or feel pulsating in the front if its not just smooth braking then the rotors are warped. Real easy to warp a rotor just do a hard emergency stop at very fast speed and then sit there with your foot on the brake with the super hot pads against the rotor. That should do it. if the rotors are warped you'll know it when you brake.

But i thought you had vibration in another thread.
