How long can the front wheel bearings of the car generally be used？
100,000 to 300,000 kilometers
The service life of front wheel bearings is usually between 100,000 km and 300,000 km. This range is affected by a number of factors, including the quality of the bearings, the driving conditions of the vehicle, driving habits and whether regular maintenance and inspections are carried out. case
Under ideal circumstances, if the bearing is well maintained and maintained, its life can reach more than 300,000 kilometers.
However, if not properly maintained, bearings may need to be replaced after only 100,000 km of use. On average, the average life of wheel bearings is roughly between 136,000 and 160,000 km. In some special cases, the service life of the bearing can even exceed 300,000 kilometers.
Therefore, in order to extend the service life of the bearing, regular inspection and maintenance is recommended, especially after driving to a certain distance.
What phenomenon will occur when the front wheel bearing of the car is broken?
01 Tire noise increases
The obvious increase of tire noise is an obvious phenomenon of automobile front wheel bearing damage. When the vehicle is moving, the driver may hear a constant buzzing sound, which becomes louder at higher speeds. This buzzing is caused by bearing damage, which not only affects the comfort of driving, but can also be a precursor to damage to other parts of the vehicle. Therefore, once the abnormal increase in tire noise is found, it should be checked and maintained in time to avoid possible safety hazards.
02 Vehicle deviation
Vehicle deviation may be a sign of damage to the front wheel bearing. When there is a problem with the front wheel bearing of the car, the wheel may wobble during the driving process, leading to the acceleration of the vehicle shake. This jitter not only affects the driving comfort, but also may cause the vehicle to run off at high speed. In addition, damaged bearings may also affect the suspension system and steering system, which may lead to traffic accidents in serious cases. Therefore, once it is found that the vehicle runs off or the wheel wobbles, the front wheel bearing should be checked as soon as possible and replaced in time.
03 Steering wheel shake
Steering wheel shaking is an obvious phenomenon of the damage of the front wheel bearing. When the bearing is damaged to a certain extent, its clearance will increase significantly. This increased clearance will cause significant shaking of the body and wheels at high speeds. Especially when the speed is increased, the shaking and noise will be more obvious. This shake will be directly transmitted to the steering wheel, making the driver feel the shaking of the steering wheel during the driving process.
04 Temperature rise
Damage to the front wheel bearing can cause a significant increase in temperature. When the bearing is damaged, the friction will be intensified and a lot of heat will be generated. This high temperature will not only make the bearing box housing hot, but also may affect the operating temperature of the entire engine. In addition, if the bearing temperature is too high, it may be caused by the quality grade of the grease does not meet the specified requirements or the proportion of grease in the bearing internal space is too high. This high temperature condition not only affects the vehicle performance, but also may shorten the service life of the bearing.
05 Driving unstable
Running instability is an obvious phenomenon of the damage of the front wheel bearing. When the bearing is excessively damaged, the vehicle may shake when driving at high speed, resulting in unstable driving. This is because the damaged bearing will affect the normal operation of the wheel, which in turn affects the stability of the vehicle. Since the bearing of the wheel is an irreparable part, once damaged, it can only be solved by replacing a new part.
06 Increased friction
Damage to the front wheel bearing can lead to increased friction. When there is a problem with the bearing, the friction between the wheel and the bearing will increase during the driving process, and this increased friction will not only cause the vehicle to generate high heat after driving, but also may further damage other vehicle components, such as the brake system. Therefore, once the vehicle is found to have abnormal friction or high temperature phenomenon, the front wheel bearing should be checked as soon as possible.
07 Poor lubrication
Poor lubrication of front wheel bearings can lead to a variety of problems. First, friction increases, which can cause the bearing to overheat, which in turn affects its life. Secondly, due to the increased friction, the vehicle may produce abnormal noises, such as squeaking or buzzing. In addition, poor lubrication can also lead to bearing damage, further affecting the vehicle's handling and safety. Therefore, regular inspection and replacement of lubricating oil is an important step to maintain the normal operation of automobile front wheel bearings.
