Rear wheel bearing is broken symptom is what?
The rear wheel bearing is an important part of the vehicle to bear the weight of the body and provide rotation ability, if it is damaged, it will bring a series of problems to the vehicle. The following are the three main symptoms of rear wheel bearing damage:
1. Abnormal sound: When the tire bearing is damaged, the vehicle will emit a "buzz" noisy abnormal sound during driving. This is one of the most common symptoms.
2. Body shake: When the bearing damage is serious, the vehicle will appear body shake at high speed. This is caused by increased bearing clearance.
3. Unstable driving: When the rear wheel bearing is excessively damaged, the vehicle will appear unstable driving and erratic power at high speed. This will affect the stability of the vehicle and bring safety risks to driving.
It should be noted that the working environment of the rear wheel bearing is very bad, and it needs to withstand the pressure, vibration, and the invasion of rain and sand during the driving of the vehicle. Therefore, even if high-quality bearings are used, they cannot be completely guaranteed against damage. If you find that the vehicle has the above symptoms, it is recommended to check and replace the rear wheel bearings in time to ensure the safety of driving.
What are the reasons for the abnormal noise of the rear wheel bearing of the car?
Automobile rear wheel bearing abnormal noise may be caused by a variety of reasons. Among them, too little oil separation in the bearing, insufficient lubrication of the bearing groove and the steel ball will lead to different rotation sounds; When the bearing inner ring is separated too tightly, the bearing contacts with the clutch diaphragm spring, resulting in friction between the bearing inner ring and the diaphragm spring. The lower assembly height of the separation bearing or the sinking of the inner ring after long-term work will lead to the contact between the outer ring and the diaphragm spring, resulting in abnormal friction. The diaphragm spring of the clutch is not separated on the same plane, and the bearing will be separated from the finger intermittently when rotating. In addition, the elasticity of the diaphragm spring decreases after a long time of work, the separation refers to the reversal, the bearing outer ring and the separation refers to the friction, and will also produce abnormal sound.
In order to ensure the normal operation of the rear wheel bearing, we should pay attention to the following points: First, regularly check the oil separation of the bearing to ensure adequate lubrication; Secondly, check whether the bearing inner ring separation is too tight to avoid friction with the diaphragm spring; In addition, pay attention to the assembly height of the separation bearing to avoid contact with the diaphragm spring and produce abnormal sound; Finally, check the elasticity of the clutch diaphragm spring to avoid a decrease in elasticity after a long time of work and abnormal sound.
The car bearing is broken can not continue to drive, otherwise it will bring serious consequences.
If not handled in time, it will pose a threat to driving safety. Bearing failure will lead to vehicle noise, wheel abnormalities, affecting driving stability. In addition, it produces vibration and reduces power, increasing the risk of accidents at high speeds. Moreover, the broken bearing will also lead to the abnormal temperature of the rear hub, so that the surface of the hub is hot, which is easy to cause a tire explosion accident. Therefore, when there is a problem with the bearing, it should be replaced immediately to ensure driving safety.
To be specific:
Vehicle noise and abnormal phenomena: After the bearing is damaged, the vehicle will have a lot of noise, such as buzzing, which will not only affect the driving comfort, but also may indicate that the vehicle has other problems, such as deviation, wheel abnormalities, etc.
Steering and powertrain problems: Bearing damage can cause the steering wheel to vibrate and even squeak when it turns, which can affect the normal operation of the steering system and cause power loss and body shake at high speeds, increasing the risk of accidents.
Suspension and hub damage: Bearing damage can also lead to suspension damage, which can affect vehicle stability and handling. In extreme cases, bearing damage can lead to wheel mechanism damage, such as hub loss, which further increases the likelihood of an accident.
Safety hazards: After the bearing is damaged, the temperature of the rear wheel hub of the car may increase abnormally, especially in the long driving time or in the high temperature season, which may lead to a flat tire, resulting in serious traffic accidents.
Therefore, once the bearing is found to be damaged, it should be stopped immediately and repaired or replaced as soon as possible to avoid the above-mentioned potential safety risks.
