  • Noisy Operation: Grinding, whining, or clunking noises when turning could indicate internal damage or insufficient lubrication in the steering rack.
  • Fluid Leaks: Look for power steering fluid leaks under the vehicle. Leaks can significantly impair the steering system’s function, causing further complications.
