Grinding noise

Well don't turn left! Three right turns makes a left turn. :)

Actually, to help diagnose this, you need to be more specific. Does this only occur when the car is moving? Will it occur if the car is standing still and you turn the steering wheel? Can you tell the area the noise is coming from? How many miles are on the car?

The most common suspect would be worn brake pads or a splash shield that is rubbing on the brake rotor. Worn pads can cause grinding when applying the brakes, in some cases the grinding stops when applying the brakes, and sometimes they rub on a ridge of rust on a rotor when the rotor is under sideways pressure from turning a corner.

There are other possible causes like a tire rubbing on the inner fender, or a non-standard wheel rubbing on a brake caliper. Calipers move sideways about 3/8" over the life of the brake pads, and that can bring them closer to a wheel over time.

The best approach is to have the steering and suspension systems inspected at a tire and alignment shop. The people there are experts at finding the causes of noises, vibrations, and bad tire wear.
