The common trouble of car wheel bearings

Knowing the signs of the cause of wheel bearing hub will damage their grinding noise when driving.

check wheel bearingsFriction is generated traction any moving mechanical parts of the vehicle. Various mechanisms designed to combat friction, including lubrication and the use of continuous friction reducing vehicle components such as wheel bearings.

A bearing is placed on the axle of the wheel hub car, to reduce metal-to-metal surface contact friction and let the wheels spin freely. This is an important component of the car’s suspension. Although the bearings are lubricated, they eventually wear out over time. Wearing out can be accelerated by dirt and other contaminants into the assembly.

Although the wheel bearings have a seal cover, the water still get into the bearings and can cause rust, as well as causing contaminate the lubricating oil. The wheel also handle the weight of the vehicle along with friction tires. Although, bearing usually built to last for more than 150,000 miles, friction does not take its toll eventually and wears them out. The problem with the bearings are mostly due to wear or seal the leak.

Knowing the symptoms.
Diagnose car problems requires an eye for small detail and an ear for sound abnormal. You do not need to be a car to see the symptoms of car trouble. To diagnose the problem, you should know the symptoms that indicate bad bearing. Here is a list of the main symptoms.

Grinding noise.
Friction always produces noise and heat while slowly pressing down on the move. Symptoms of worn wheel bearings are noise, vibration. or roar. which can be heard around the wheels when moving. The volume and intensity of this noise is generally proportional to the speed of the vehicle and does not change much while slowing down.

During the turn, the noise can get louder or even disappear. This is a signal that you need to pay attention to the condition of bearings and get them replaced as soon as possible. If the problem is ignored long, they may rupture suddenly and the wheels may be dislodged, causing a major accident! In fact, it could happen only in very extreme cases the wheel bearing wear, it is important that you pay attention to it as soon as possible.

Rotation of the wheel.
Another important symptom is the distance play or looseness of the wheel. As the pads wear out, they lose their shape and let the wheel hub and spindle to go loose. This misalignment hub, eventually causing the wheels to go loose. To check rotation of the wheel, just raise your vehicle on a jack and pull or push the tire. Excessive rotation of the wheel rocking indicates that the pads have worn to a great extent and need immediate replacement.
