How to recognize a bearing failure?

The bearing is the part that allows the bearing element to rotate. They are located in different places of the car and are responsible for the correct functioning of the systems. Unfortunately, like all other parts, they can fail. Then they must be replaced immediately before the damaged element reduces the level of traffic safety. Today we will advise you on how to recognize the symptoms that should bother you.

TL, д-

While bearing failure can have many causes that are not directly related, the symptoms are usually the same, although they may vary slightly for each component. Some of them only show up as unpleasant sounds, while others make it much more difficult to drive the car correctly. Ignoring a problem or postponing a visit to a mechanic can lead to more serious damage. However, there are some methods that can reduce the risk of bearing failure.

Causes of Bearing Failure

In most cases accident bearings occurs due to the use of too much or too little lubricant. Also use improper lubrication extremely harmful. Often the failure also occurs due to contamination caused by liquid or solids entering the bearing – often this is a lubricant leak. Sometimes problems result from incorrect assembly, consisting in improper adjustment, overheating or power installation of this element.

It can also crash incorrect selection of the bearing for the car modelinadequate maintenance of parts, damage to systems adjacent to the bearing, improper driving (for example, wheels often hit the curb and tow), crack in the outer ring, deviation from the vertical, dents in the rolling elements, incorrect load direction and corrosion.

Diagnostics of failures

Alarms that may indicate bearing failure include: vibrations, rattles and any disturbing noises coming from under the floor of the vehicleespecially on the wheels. However, certain types of bearings have more specific and distinctive symptoms.

Wheel bearings

Wheel bearings are designed to provide the highest possible durability and efficiency. They are primarily responsible for the damage caused to them. external factors... Failure of this element usually portends the failure of this element. driving noise... The bearing becomes hot, which makes it difficult for the wheel to rotate freely. The most advanced glitch appears tilt angle change.

Rear wishbone bearings

Wear on the rear wishbone bearings results in characteristic noises such as rear suspension creaking and knocking when driving over bumps... The wheels can tilt and vibrate. In this case, the rear of the vehicle begins to behave in an uncontrolled manner. Too late intervention leads to the need to replace not only the bearings, but also the rear beam.

Axle support bearings

In a center shaft drive, the thrust bearing can wear out. As a result of backlash, accelerated wear of other elements of the drive system also occurs. In this case, signs of wear vibration in the drive system... Failure of the propeller shaft support bearing significantly complicates driving.

Cardan shaft support bearings

Driveshaft bearing wear is a common problem in rear wheel drive vehicles. This type of damage appears strong vibration from under the floor... Their intensity can vary depending on the speed of rotation of the drive shaft. Neglect leads to the detachment of the element.

Can failures be avoided?

There is never a XNUMX% guarantee that bearings will not fail. You can only reduce the risk of its occurrence, postpone it on time and minimize losses... It is enough to drive the car correctly, avoiding holes and irregularities in the surface as much as possible and to prevent the car from skidding (the so-called skidding). Also, be careful not to hit the curbs when parking.

Moreover, he must buy the necessary spare parts, strictly adapted to a specific make and model of a car... Before buying, it is worth asking a specialist about everything in detail. In turn, it is better to entrust the assembly of bearings and other elements to an experienced specialist with a good reputation. Also, do not forget about regular and thorough removal of dirt around the bearingsespecially in winter and after.

Ignoring bearing failure can have serious consequences. Unfortunately, this happens much more often than the average driver expected. Therefore, you should react in advance to any alarming symptoms in order to protect yourself, passengers and other road users.
