1. Worn Brake Pads: Check the brake pads on the rear left wheel. If they are worn out or need replacement, they can cause a squeaking sound when the brake is applied.
2. Wheel Bearing Issue: A worn or damaged wheel bearing can cause a grinding or squeaking noise when turning. Jack up the rear of your vehicle and check for any play in the wheel by grabbing it at the top and shaking it. If there is significant movement, the wheel bearing may need to be replaced.
3. Loose Lug Nuts: Ensure the lug nuts on the rear left wheel are properly tightened. Loose lug nuts can cause a knocking or squeaking noise when turning.
4. Worn or Damaged Tire: A worn tire or a tire with sidewall damage can cause a variety of noises, including squeaking. Inspect the tire for any signs of wear or damage.
5. Suspension Component Issue: Check the suspension components in the rear left corner of your vehicle, such as the control arms, ball joints, and tie rods. If any of these components are worn or damaged, they can cause a squeaking noise when turning.
6. Brake Caliper Issues: Check the brake caliper on the rear left wheel for any issues like a sticking piston or worn-out brake caliper slide pins. These issues can cause the brake pads to drag against the rotor and produce a squeaking noise.
If you are unable to identify the source of the noise or are not comfortable performing these checks yourself, it's best to have your vehicle inspected by a qualified mechanic to diagnose and fix the issue accurately.
