Repair Wheel Hubs

Usually, the wheels are getting energy from the engine, which makes them spin and move the vehicle. They are connected to the steering mechanism, which turns them according to the motion of the steering wheel. If the wheel assembly becomes damaged, it can be dangerous to drive with it on the road. In this article, we will explain the importance of the wheel hub assembly and the various failure symptoms which will help you to determine the issue.

Construction and Function of Wheel Hubs

The hub is the center of the wheel, and typically houses a bearing, and is where the spokes meet. It is made of metal that has metal studs on its surface. The hub houses the wheel bearing and supports the lugs. The wheel bearings assist the wheels in turning smoothly. The wheel hub is attached to the brake rotor. Generally, the wheel hub provides the power to the wheels in order to rotate.

ABS Sensors in Wheel Hubs

Almost most of the modern vehicles are equipped with an ABS (anti-lock braking system) sensor in the wheel hub assembly. The ABS sensor is a type of tachometer or a sender device used for reading the speed of the vehicle's wheel rotation and passes it to the car's Engine Control Module (ECM). The ABS sensor helps to maintain all the four wheels’ speed equal as they don’t rotate with the same speed, and together with the ECM protects from the wheel lock-up. The ABS brakes react faster than a manual brake, that’s why when the ABS brake is engaged, it makes a grinding noise in some vehicles.

Causes of Defective Wheel Hubs

One of the most common cases, when the wheel hub starts to turn bad, is the worn out bearings in the hub due to age and accumulation of debris. If the wheel bearings go wrong, your car starts to pull to one side when driving. As the wheel hub assembly is designed to protect your wheels, any problems in the hub and its components can cause the wheel and tire damage as well. If you hear a whirring or squealing noise from the wheel in sudden turns, then the issue can be in the wheel hub of your car. Together with the wheel hub, the ABS sensor can fail as well as it is a part of the hub and it will indicate the failure on the dashboard of your vehicle.

The Significance of the Right Installation

It is critical to pay more attention to the wheel hub assembly as it is the central part that connects the wheels to the car. As soon as you remove the wheels of your vehicle, you will first see the wheel hub.

The wheel hub is easy to install if you have mechanical skills. During installation, the wheel hub needs to be torqued to the specified values. Some manufacturers will not let you warranty the defected part if it happened during the installation. That’s why you should always follow the owner’s manual while replacing the wheel hub. Before purchasing the wheel hub, keep in mind that the configurations of ABS included in wheel hubs are different in various vehicles. That’s why you should make sure that you chose the right replacement part for your car.
