1. Wheel Bearing: A worn-out wheel bearing can cause a loud grinding or humming noise that increases with speed. It can also cause the wheel to wobble or feel loose.
2. Brake Pad or Rotor Damage: Worn-out brake pads or rotors can produce a squealing or grinding noise, especially when braking.
3. Driveshaft Problem: If the driveshaft is damaged or worn out, it can also produce a loud clunking sound. The driveshaft transfers power from the transmission to the wheels. If it is damaged or worn out, it can cause the rear end of the car to shake and make a loud noise.
4. Axle Problem: If the axle is damaged or worn out, it can cause the rear wheel to make a loud noise.
5. Loose Lug Nuts: Make sure the lug nuts on the passenger-side rear wheel are properly tightened.
Steps to Diagnose and Fix:
1. Check the wheel bearing: Jack up the rear of the car and spin the passenger side wheel by hand. If you hear a grinding or humming noise, the wheel bearing may be worn out and needs to be replaced.
2. Inspect the brake pads and rotors: Remove the wheel and inspect the brake pads and rotors for wear or damage. If they are worn out or damaged, they will need to be replaced.
3. Inspect the driveshaft: With the vehicle off and in park, crawl underneath and visually inspect the driveshaft. Look for any signs of damage, such as cracks or bends. If you suspect an issue with the driveshaft, it's best to consult a professional.
3. Check the axle For axle issues, inspect the area around the wheel hub and suspension components. Look for any bent, broken, or loose parts. If you suspect axle damage, consult a qualified mechanic.
4. Tighten the lug nuts: If the lug nuts on the rear passenger-side wheel are loose, tighten them using a lug wrench. Ensure they are snug but not over-tightened.
If you are unable to identify the source of the noise or are uncomfortable performing repairs yourself, it is best to take your vehicle to a qualified mechanic for diagnosis and repair.
