A car steering system uses ball bearings to support the steering column, reduce turning friction, and allow easy and smooth steering.

A car wheel ball bearing is used to connect a wheel to an axle. They are positioned as a group of bearings that sit neatly next to each other inside a metal ring known as a race. Bearings allow a car wheel to rotate freely without experiencing friction. They are designed to perform two critical tasks - support the weight of the vehicle and allow the wheel to rotate freely with as little friction as possible.

Ball and roller bearings are available with different types of metallic shields and seals. These are commonly referred to as bearing closures.

Ball bearings are used throughout a car engine in areas such as the camshaft and crankshaft to reduce friction and facilitate smooth movement.

The first thing you'll notice when a bearing gets damaged is an increase in vibrations. If a bearing has been damaged in a wheel assembly you will notice vibration in the steering wheel you drive. Other symptoms of damaged wheel bearings include steering wheel looseness, excessive noise, and ABS malfunction – see below.

Poor installation is a regular cause of premature ball bearing failure. It's especially common when aged parts are used in the assembly such as bolts, split pins, and seals. When bearings are installed or repaired they should be installed with new accessories to maximise their lifespan.

Ball bearings are used to support and guide the rotating gears in a transmission assembly to facilitate smooth gear changes while driving.

Impact damage is one of the most common causes of car bearing damage. Wheels striking potholes, speed bumps, and kerbs are common sources of ball bearing damage. These episodes increase bearing wear and shorten the lifespan of the bearings.

Ball bearings are usually made from steel or ceramic for strength and durability. They are shaped like little balls and are neatly packed inside the wheel assembly to separate two moving surfaces. Bearings are designed to withstand high temperatures and strain. They are amongst the hardest-wearing components in a car.

Damaged ball bearings can cause excessive looseness in the steering wheel. This can feel like the steering wheel is unresponsive.

Damaged ball bearings need to be replaced by a professional mechanic. The job involves the use of specialist tools and an understanding of torque values for your vehicle. Ensuring damaged bearings are replaced correctly is essential for vehicle safety and performance. If your car ball bearings are damaged – get in touch with your local mechanic and make an appointment to have the vehicle dropped in and repaired.

Most manufacturers recommend an interval at which bearings should be replaced. This is usually dictated by the mileage clocked up by the vehicle. However, many of us tend to ignore manufacturers' recommendations and continue to drive our cars until we notice something has gone wrong. So, if you choose to ignore the recommendations – how do you know when the bearings need replacing?

Overloading a vehicle with excessive weight can damage wheel ball bearings. If the weight of the vehicle exceeds the recommended load of the bearings it can cause the bearings to deform and distort the bearing race.  This is bad news.

The main causes of wheel ball bearing damage are impact damage, overloading, poor installation, driving conditions, and the use of poor-quality ball bearings. However, even properly installed good quality bearings will fail over time. They have a limited lifespan and the factors listed below will eventually wear and damage the bearings.

When the car is in motion the bearing balls roll along inside the metal race allowing the wheel to rotate. The bearing assembly is lubricated with grease or oil to reduce friction and facilitate smooth motion. Wheel bearings are an essential component of any vehicle, without them a vehicle would be unable to move.

Certain modifications can increase the load on the wheel bearings and have a negative impact on their expected lifecycle. These include fitting wheels with wider rims, adding stiffer shock absorbers, and using tyres with reduced thread walls.

The first layer of plant immunity is activated by cell surface receptor-like kinases (RLKs) and proteins (RLPs) that detect infectious pathogens. Constitutive interaction with the SUPPRESSOR OF BIR1 (SOBIR1) RLK contributes to RLP stability and kinase activity. As RLK activation requires transphosphorylation with a second associated RLK, it remains elusive how RLPs initiate downstream signaling. We employed live-cell imaging, gene silencing and coimmunoprecipitation to investigate the requirement of associated kinases for functioning and ligand-induced subcellular trafficking of Cf RLPs that mediate immunity of tomato against Cladosporium fulvum. Our research shows that after elicitation with matching effector ligands Avr4 and Avr9, BRI1-ASSOCIATED KINASE 1/SOMATIC EMBRYOGENESIS RECEPTOR KINASE 3 (BAK1/SERK3) associates with Cf-4 and Cf-9. BAK1/SERK3 is required for the effector-triggered hypersensitive response and resistance of tomato against C. fulvum. Furthermore, Cf-4 interacts with SOBIR1 at the plasma membrane and is recruited to late endosomes upon Avr4 trigger, also depending on BAK1/SERK3. These observations indicate that RLP-mediated resistance and endocytosis require ligand-induced recruitment of BAK1/SERK3, reminiscent of BAK1/SERK3 interaction and subcellular fate of the FLAGELLIN SENSING 2 (FLS2) RLK. This reveals that diverse classes of cell surface immune receptors share common requirements for initiation of resistance and endocytosis.

Low-quality wheel bearings will fail prematurely. Bearings are under constant high pressure and need to be manufactured to the highest standards to function properly and withstand their substantial workload.

Another sign of damaged car ball bearings is whining and growling noises. The noises change as you accelerate or turn the vehicle.

Car ball bearings are components of a car's wheel assembly that allow it to bear weight and move smoothly. They are used to connect the car wheel to the axle and allow a wheel to perform two vital tasks – rotate fluently and support the weight of the vehicle. Without ball bearings, a car would grind to a shuddering halt.

The ABS system is integrated with the wheel bearing assembly. And when the bearings get damaged the ABS system can fail.

Poor driving conditions can cause contamination that damages bearings – especially over time. If debris, dust, or water gets into the bearing assembly. This happens when water or mud squeezes past the seals and makes its way into the bearings.

If you notice any of the symptoms listed above for a damaged wheel ball bearing you should stop driving your car. While it is rare for a ball bearing to completely fail immediately after noticing there is an issue – it is still recommended you address the problem as soon as possible. Car ball bearings are essential components that connect the wheels to the car, support the weight of the vehicle, and allow the wheel to rotate. You should not drive your car if the ball bearings are damaged. Doing so is a serious safety concern and could cause lasting damage to your drive-axle and steering assembly.

A car ball bearing typically lasts between 85,000 to 100,000 miles – equivalent to 136,000 to 160,000 km. However, the lifespan of a wheel ball bearing will largely depend on the type of bearing, the quality of the bearing, and the operating conditions it is exposed to. Wheel ball bearings that suffer harsh operating conditions such as heavy loads, poorly maintained roads, and persistent high speeds will have a shortened lifespan. Other factors that can shorten the lifespan of a car ball bearing include inadequate lubrication, poor installation, and the presence of dirt or debris in the bearing assembly.

The first sign that you have a problem with your wheel bearings is a vibration in the steering wheel. You will notice that the level of vibration changes as you change speed.
