1. Low Power Steering Fluid: If the power steering fluid level is low, the pump may not be able to generate enough pressure to properly assist the steering. This can cause a grinding noise when turning the wheel. Check the power steering fluid reservoir and top it up if necessary.
2. Worn Steering Rack: The steering rack is a component that connects the steering wheel to the wheels. If the steering rack is worn out or damaged, it can cause a grinding noise when turning the wheel. This is more likely to occur in older Mustangs with high mileage.
3. Worn Steering Column: The steering column is the shaft that connects the steering wheel to the steering rack. If the steering column is worn out or damaged, it can also cause a grinding noise when turning the wheel.
4. Damaged Steering Linkage: The steering linkage consists of several rods and joints that connect the steering rack to the wheels. If any of these components are worn out, damaged, or loose, it can cause a grinding noise when turning the wheel.
5. Worn Wheel Bearings: The wheel bearings are located in the wheels and allow the wheels to rotate smoothly. If the wheel bearings are worn out or damaged, they can cause a grinding noise when turning the wheel.
6. Worn CV Joints: The CV joints are located at the ends of the front axles and allow the wheels to turn at different angles. If the CV joints are worn out or damaged, they can also cause a grinding noise when turning the wheel.
7. Binding Brake Calipers: In some cases, binding brake calipers can cause a grinding noise when turning the wheel. This is because the brake pads are constantly rubbing against the rotors, even when the brakes are not applied.
8. Loose Bolts or Fasteners: Loose bolts or fasteners in the steering system can also cause a grinding noise when turning the wheel. Make sure all the bolts and fasteners are properly tightened.
