Hello y'all, I own a Toyota Prius from 2007, 2nd gen, and after driving 1200 miles, I have noticed a sound (like a rumble, or something rotating) coming from the back of the car, most probably the wheels. This happens while driving and also when I brake. I have recorded the sound, video can be found here: Anyone has any idea where this noise is coming from? Thank you.
But what is the total mileage on the odometer in the car I get that you drove 1200 that's great so I'm guessing there's 170,000? We're following among these lines I would just change the rear wheel bearings You don't have to buy the most expensive one but do not buy the most inexpensive one nothing really fancy about this type of bearing or layout similar is used on the Yaris Corolla and other cars with similar rear end setups so like I say you should be good.
Have you inspected your rear pads and rotors? While you're back there, it wouldn't hurt to remove the brake drums to check on the condition of the drums and parking brake shoes?
