1. Wheel Bearing: A faulty or worn-out wheel bearing can produce a grinding or growling noise, especially when the vehicle is turning or under load. Check for any play or looseness in the wheel bearings by lifting the car and rotating the wheel by hand.
2. Brake Components: Worn-out brake pads, rotors, or calipers can cause grinding noises when the brakes are applied. Inspect the brake pads for thickness (should be at least 1/4 inch), check for uneven wear on the rotors, and ensure the calipers are functioning properly.
3. CV Axle: A damaged CV (constant velocity) axle can also cause a grinding or clicking noise when the vehicle is turning. Look for any torn CV boot, grease leakage, or excessive play in the axle joints.
4. Power Steering System: Issues with the power steering pump, hoses, or steering rack can produce groaning or whining noises. Check the power steering fluid level and inspect the steering components for leaks or damage.
5. Suspension Components: Worn-out or damaged suspension components such as ball joints, control arm bushings, or tie rod ends can cause grinding or knocking sounds over bumps or rough roads. Visually inspect the suspension for any signs of wear or damage.
6. Driveline Components: Problems with the driveshaft, differential, or transmission can also result in grinding noises. Listen carefully to identify if the noise is coming from the front right or another area of the vehicle.
7. Loose Bolts or Nuts: In some cases, a simple loose lug nut or bolt in the right front wheel area can cause a grinding or scraping sound while driving. Always double-check that the lug nuts and bolts are properly tightened.
If you're not comfortable inspecting or repairing the vehicle yourself, it's best to have a qualified mechanic diagnose the exact source of the noise and recommend the necessary repairs.
