A set of small ball bearings are located behind almost every wheel on modern vehicles, ensuring uninterrupted wheel rotation. Whenever it comes to assessments of a car's essential components, they are real heroes, yet their significance cannot be understated. Even though these little balls are not typically maintained, they ultimately wear out, so understanding how they function will be beneficial when it comes down to replacements.
Brief Definition Of Wheel Bearing
A wheel bearing is a bearing that helps to support the weight of a vehicle and allows the wheel to rotate smoothly. It consists of two metal rings, called races, and a set of small metal balls held in place by an inner and outer ring. The inner ring is connected to the wheel hub, while the outer ring is connected to the rim.
Difference Between Ball Bearings Vs. Roller Bearings
Ball bearings are the most familiar type of bearing and consist of an outer ring, an inner ring, and a set of balls. The balls are held in place by a cage, which keeps them evenly spaced and prevents them from meeting each other. Ball bearings are typically used for moderate radial loads and low axial loads.
Roller bearings are like ball bearings, but instead of using balls, they use cylindrical rollers. Roller bearings can maintain heavier loads than ball bearings due to their increased surface area. As a result, they are often used for high radial and moderate axial loads.
How Long Do They Last?
The lifespan of a wheel bearing depends on the type of bearing, the weight of the vehicle, driving conditions, and the quality of the bearing. Generally, wheel bearings can last up to 150,000 miles or more if maintained properly.
How Can You Inspect A Bad-Wheel Bearing?
The incredible thing about a wheel bearing is that you can tell when it's damaged because of a few clear signs. So here are some warning flags you must examine before driving. So that if there is any damage, you can buy tyres in Dubai for your car.
- Abnormal Noises
- Rough Tire Wheel
- Loose-fitting Steering Feel
- Wheel Lock
- ABS Fault
1. Abnormal Noises
The first step in inspecting a bad wheel bearing is to check for any signs of wear. This can include excessive play in the bearing, noises coming from the bearing, or a grinding sound when the wheel is rotated. The wheel bearing should be removed and inspected for damage if these signs are present.
2. Rough Tire Wheel
A visual inspection should be done to look for any signs of destruction, such as cracks, wear, or corrosion. If the bearing shows any of these signs, it should be replaced immediately. On the other hand, if the bearing is still in good condition, it should be re-lubricated and reinstalled.
3. Loose-Fitting Steering Feel
Unfortunately, the steering wheel won't feel loose by itself; however, the steering sensation might. The wheel assembly may have some play if a bearing malfunctions. Your steering may feel fuzzier than usual if this happens.
There may be vibrations and a harsher ride than typical if a wheel bearing seal is damaged and the interiors are contaminated with hard particles or if it has merely worn down gradually.
5. Wheel Lock
There is a concrete reason why many current wheel bearings are sealed. The lubrication of the bearings may be reduced, and friction may rise if any debris, dirt, or other pollution enters them. The bearings could begin to grind or lock up if it becomes excessively hot or has too much debris. The wheel might lock if the bearings stiffen up.
6. ABS Fault
Almost all modern wheel hub assemblies have sensors that provide information about stability control, ABS, power steering, and other driver assistance systems. As a result, the systems may glitch, a code may be generated, or a warning light may illuminate if something inside the wheel bearing isn't operating properly.
