Grinding or low-pitched humming noises could indicate worn-out or failing components in your Toyota Camry. A low-pitched hum emanating from beneath your vehicle might suggest issues with the transmission, universal joints, wheel bearings, or differential. Among these, the most common culprit is usually a faulty wheel bearing. This vital part consists of steel balls enclosed in a metal race, housed within the hub of your wheels. Properly functioning wheel bearings within the hub reduce friction as the wheel rotates on the metal axle shaft. Driving with a worn-out bearing can pose serious risks since it may lead to wheel failure while in motion. Furthermore, a damaged wheel bearing can cause excessive strain on the hub, CV joint, and even the transmission itself.
If your Toyota Camry is producing a buzzing sound, it might be a sign that your air conditioning system needs to be refilled with refrigerant.
