Car Grinding Noise when Accelerating If your car makes noise when accelerating, it can be a problem like a worn-out clutch disc or wheel bearing. That can be a clutch problem in a manual transmission, an automatic transmission issue, a worn u-joint or CV joint, or something in the brakes, suspension or steering.
Grinding. If your car has an automatic transmission, one of the most disconcerting noises that you can hear coming from your transmission is a grinding noise. If you suspect that the planetary gear system in your transmission is damaged, you need to schedule a maintenance check right away.
Scraping or grinding noises you hear while driving or turning can be caused by the following issues: Worn or failing brake parts: Unevenly worn or rusted rotors or worn or thin brake pads. Worn dust shield that’s moved closer and contacting the brake rotor. Loose, worn, damaged, or failing wheel bearings.
Usually this type of noise in an indication of a exhaust leak or a vacuum leak due to a broken or disconnected vacuum line. If you also notice that your car is slow to accelerate or is running rough, then it is likely that one of these items is the root cause.
Clunking, humming or whining sounds are signs of automatic transmission problems. Faulty manual transmissions will also give off loud machinelike sounds that seem to come out of nowhere. A clunking noise when you shift gears is a telltale transmission situation.
Low Oil Level If you’re hearing a grinding or loud rubbing sound, make sure to check your engine oil levels. While most newer cars include engine oil level monitors, older cars may not have this, or the sensor may not be working. It’s always a good idea to check the engine oil level if you’ve noticed grinding sounds.
Transmission Trouble: 10 Warning Signs You Need Repair Refusal to Switch Gears. If your vehicle refuses or struggles to change gears, you’re more than likely facing a problem with your transmission system. Burning Smell. Neutral Noises. Slipping Gears. Dragging Clutch. Leaking Fluid. Check Engine Light. Grinding or Shaking.
The top signs why your transmission may be failing: Transmission won’t engage or stay in gear. Shifts are delayed or missing gears. Transmission slipping or engine is revving high. Transmission fluid is leaking. If there’s a burning smell. If there is buzzing, clunking, humming noise. Car has no power.
Transmission Fluid Another common cause of grinding gears is low or poor quality transmission fluid. If there isn’t enough fluid lubricating the gear system or the fluid itself is old, dirty, burnt or full of debris, then there won’t be enough lubrication.
Here are some indicators of a worn wheel hub bearing or other wheel -end damage: Snapping, clicking or popping. Grinding when the vehicle is in motion. Knocking or clunking. Humming, rumbling or growling. Wheel vibration and/or wobble. Shudder, shimmy or vibration at a constant speed.
If you notice a grinding or grating noise coming from your wheel or tire, take note that this is very likely caused by a bad wheel bearing —especially if the noise gets louder as the vehicle accelerates. Another revealing sign of bad wheel bearings: A car that feels loose as you drive it.
Most people describe a bad wheel bearing as making a growling or rumbling noise (the sound is often mistaken for worn tires). Also, in some cases, a bad bearing may make a high-pitched grinding or squealing sound. In either case, the frequency of the sound will correspond to the rotation of the tires.
