On each revelution of the back wheel on a certain part of it there is a sound like scraping

check the pad thickness as the noise may be from a tin scraper that is touching the rotor to let you know that you need a brake job.

Possibly a broken wheel bearing. Have a mechanic check it out.

Rotors are easy to replace, but I doubt that's the problem. What you need to do is jack up the car, take the wheel off, and see exactly what is scraping. It could be something simple like the splash shield touching the rotor. This is easy to bend back--10 minutes, problem solved. Sometimes, if it's on a drum brake, rust will build up on the drum to the point of scraping the back plate. Again, easy to solve by knocking the rust plates off the drum. OK?

You need to replace the wheel bearing assembly on the drivers side.

Yup they are too big...
The tires are scraping the wheelwell behind the front wheels.

Turn wheels to the far right and inspect the back of the left tire. It is worn. Now look at the right wheel, you will see the scraping tire on the wheelwell.

Your speedometer is also wrong. You are going FASTER than the speedometer shows.
This is called "bear bait" ...
If your speedometer is showing 35mph , then you are actually travelling 40mph or so...

You have also changed the effect of the drivetrain gear ratios. They are now "higher" ... better fuel economy ... worse muscle power transfer to wheels... and greater stress...
Add airbags...
Hope this helps...

Probably nothing to worry about, new brake pads take a little time to adjust. If the problem doesn't go away within a few hundred miles, then I would have a look at the brake job

Take it in for proper diagnosis - that's not supposed to happen in an 'ALL WHEEL DRIVE' - all WHEELS ARE SUPPOSED TO TURN.

Careful - a long time ago there was a recall on Toyota's T100 steering wheel shaft. It could fracture - and might cause the problem you seem to be having.

sounds like you need new brake pads and the rotors atleast turned down if not replaced
the pads should stop the noise and the rotors should stop the vibration/wobble
thanks wes
ps please rate me

If it's a scraping sound, when does it happen? If it's when you hit the brakes, then it's likely your rear brake pads/shoes are down to the metal and are scraping. This can happen when you're not hitting the brakes, however. Bad wheel bearings are usually a moaning/roaring sound that increases as road speed increases. Ditto that for differential bearings - if they go out, you usually get a roaring noise that increases the faster you go.
