Car wheels have a strange noise what happened.
Abnormal noise in car wheels can be caused by a variety of reasons, including but not limited to:
Tire problems: small stones or nails stuck in the tire gap, foreign objects sticking on the tire surface, tire aging or tire pressure is too high or too low, which may lead to abnormal sound.
Brake system problems: brake pads wear too thin or brake discs rust, may cause metal friction sound.
Bearing problems: Wheel bearings are damaged or worn, which may produce a buzzing sound, especially at increased speed.
Suspension and shock absorption problems: Faulty front shock absorbers or loose rubber components of the suspension system can cause abnormal sound.
Other factors such as tires not dynamically balanced or screws not tightened may also cause abnormal noise.
It is recommended to judge the possible causes according to the specific performance of the abnormal sound (such as the type of sound, the frequency of occurrence, etc.), and to check and repair the professional auto repair shop in time.
What symptom is the wheel bearing broken?
01 Hum
Buzzing is the main symptom of wheel bearing damage. When the vehicle is driving, the damaged wheel bearings will emit this noisy abnormal noise. The sound is usually very noticeable and can be clearly felt coming from the inside of the car. If it is determined that the bearing on one side is making this sound, the bearing of the tire can be removed for inspection. If the bearing rotates normally, it may be the lack of lubrication at the spline of the shaft, apply grease; If the rotation is not smooth, it indicates that the bearing is damaged and needs to be replaced directly.
02 Vehicle deviation
Vehicle deviation may be an obvious symptom of pressure bearing damage. When the wheel bearing is damaged, the wheel rotation will become not smooth, resulting in increased resistance, which will affect the driving stability of the vehicle. This unstable state may cause the vehicle to deviate during driving. In addition, damaged bearings can also lead to increased fuel consumption and decreased power. Therefore, once the vehicle is found to be off-track, it should go to the 4S shop or repair shop as soon as possible to check and repair, in order to avoid more serious injury to the vehicle and endanger the safety of the occupants of the vehicle.
03 The ride is unstable
Driving instability is an obvious symptom of wheel bearing damage. When the wheel bearing is excessively damaged, the vehicle may shake when driving at high speed, resulting in unstable driving. In addition, the speed of the vehicle will become unstable, and the power will become erratic. This is because bearing damage will affect the normal operation of the wheel, which in turn affects the driving stability of the vehicle. When the owner finds these symptoms, the vehicle should be sent to the repair department for inspection in time, and consider replacing the new bearing.
04 Temperature rise
The rise in temperature is an obvious symptom of wheel bearing damage. When the bearing is damaged, the friction will increase, resulting in the generation of a large amount of heat. Not only can this heat be felt to the touch, but it can also be hot. Therefore, if the temperature of the wheel part is found to be abnormally high when the vehicle is driving, this may be a warning signal that needs to be checked and repaired as soon as possible.
05 Rolling is not smooth
One of the main symptoms of wheel bearing damage is poor rolling. This situation can lead to a decrease in motivation. When there is a problem with the wheel bearing, the friction increases, making the wheel hindered when rolling, which in turn affects the power output of the vehicle. This may not only cause the vehicle to accelerate slowly, but may also increase fuel consumption. Therefore, once the phenomenon of poor rolling is found, the wheel bearings should be checked and replaced in time to restore the normal performance of the vehicle.
