Bad wheel bearing if you are referring to a grinding noise. A squeak can be many things. Loose Power Steering belt for one.
It probally is the transmission or your brakes could be slipping.
Check for a vacuum leak
For the brakes, check for warped rotors. For the turning, check for worn CV joints.
You went thru a deep puddle with hot brakes. The disc gets doused in cold water and warps.
Your 1997 Saturn rear brakes are equipped with adjustment screws. Turning the adjustment screw will adjust the brakes. The brakes should adjust themselves automatically every time you back up and hit the brakes.
The brake pad clearance is quite close and sometimes turning will result in a light scraping of the brakes against the rotor. If that happens it's usually an indication that the brakes are worn. A wheel bearing can also be worn and be most noticeable when turning. Faulty CV joints can be noisy when turning as well. If you have oversized tires or non-standard wheels the tires can rub against the fender. Unfortunately, I can't give you any more specific information without seeing/hearing the vehicle.
your rear brakes are your emergency brakes. if your handle is coming up to much you need new brakes most likely or sometimes just an adjustment.
Bring to a shop that has an ABS Scanner
NO if they stopped they would get beaten or killed
If your car makes a squealing sound when you are turning it is because your brakes have worn out. When the brakes wear down below a certain point, a wire pops loose. That makes a squeaking sound.
Inspect the steering components, suspension, and brakes.
