Wheel bearings are a vital part of a vehicle’s braking, steering and suspension systems. They’re a set of steel balls or tapered bearings that sit inside the one-piece hub assembly, located between the drive axle and the brake disc or drums. Bearings allow the wheels to turn smoothly, with as little friction as possible.
The bearings themselves are packed tightly, encase in grease and sealed into a waterproof ring. This housing, called a race, is located inside the hub and each wheel has one.

How Does A Wheel Hub Assembly Work?The hub assembly is a key part that supports the vehicle and houses the precision bearings, seals, and sensors. In front-wheel-drive cars, the front hub assembly connects the CV axle shaft, which transmits power to the wheels. Usually, a hub assembly has 4 or 5 long extended studs to which the wheel is attached, and the lug nuts hold the wheel with the hub. The front wheel hub assembly is one of the key components of the steering system crucial for contributing to the safe steering and handling of the vehicle.
The wheel hub assembly is also responsible for the working of your vehicle’s Anti-lock Braking System (ABS) and the Traction Control System (TCS). It houses the speed sensor that constantly relays the speed to the vehicle’s ABS control module. The system uses this information to engage the ABS during hard braking and prevents the vehicle from skidding. The traction control system also uses this ABS sensor to operate and offer optimum traction while driving. A wheel hub assembly consists following components:

What Is The Difference Between A Wheel Bearing And Wheel Hub Assembly?Both the hub assembly and wheel bearings allow the wheels to rotate freely. Although they are designed differently, the function and application are similar. The wheel hub assembly has a hub bearing that is housed inside the assembly and cannot be taken apart for repair. Hub bearings are a part of the hub assembly and are pre-packed by the manufacturer to be sold as a complete unit. Whereas the wheel bearings are repairable and can be removed or replaced for lubrication. Wheel bearings are mostly used in vehicles with drum brakes. However, drum brakes are less used on vehicles (only at the rear brake) and the hub assembly is used on cars today with the increasing use of disc brakes. Wheel hub assemblies also feature studs that allow the brake rotors to attach to them.

How To Identify A Bad Front Wheel Hub Assembly?Like every other moving part, a hub assembly also wears out with time and it is mostly because of a bad or damaged wheel bearing. Although the bearing in the hub assembly has a long life of 100,000 to 150,000 kilometers, sometimes they get damaged because of a failed seal or a severe impact from potholes at high speeds. It is easy to identify the signs of a failing wheel hub assembly and some of them are mentioned below:

What Is The Cost Of Replacing Front Hub Assembly?Although the wheel hub assembly replacement cost mainly depends on the car make and model you drive, the price of a new front hub assembly varies between $100 to $400. The cost of replacing the wheel hub assembly can be reduced by replacing the faulty components instead of replacing the whole assembly. On average, a wheel bearing costs you $50 to $200. Besides the cost of the parts, replacing the front or rear wheel hub assembly is labor-intensive and requires special tools and skills. The average labor cost of replacing your wheel hub assembly can vary between $120 to $180. Which makes the overall replacement cost approximately $220 to $580. Be careful while purchasing a new wheel hub assembly for your vehicle. Do not risk purchasing a cheap quality part and the expense of quality. Purchasing a good-quality wheel hub assembly is as important as selecting the correct wheel hub assembly for your vehicle. You can refer to our ultimate wheel hub assembly buying guide to ensure you choose the correct part, which can save you a lot of money in the long run.

Factors That Effect The Cost Of Wheel Hub Assembly Replacement CostThe wheel hub assembly replacement cost depends on various factors, such as the price of the component, vehicle’s make and model, labor charges, etc. Some factors that contribute to the total replacement cost are mentioned below.
Majority of the vehicles today use a complete hub bearing unit. The hub bearings are the major contributor to the total price of the unit and can cost somewhere around $80 – $300, depending on your vehicle. Other vehicles use pressed-on units which are more popular in German and Japanese cars. Although these are cheaper compared to the complete hub assembly units, the cost of replacing the bearings is comparatively more, because it involves the removal of the entire steering knuckle and the bearing has to be pressed out. This increases the labor charge, which can amount to $200 – $400, including the cost of the part. In comparison between the two, a complete wheel hub assembly costs less and is a sensible decision while saving money on the total bill.
The OEM (Original Equipment Manufacturer) wheel hub assemblies cost more compared to aftermarket ones. Aftermarket parts are a better as they will help you save money on your wheel hub repair costs because they are cheap and are offered with the same specifications, fit and function as the OEM parts. Aftermarket parts offered by reputed brands also come with OEM equivalent warranties and they meet or exceed OEM performance. Some top-quality recommended aftermarket wheel hub assemblies are mentioned below.

For example, if you own a truck like a Dodge Ram 1500, the price of hub assembly can vary between $350 to $550. Whereas, the same part costs $180 to $270 for a Honda Civic.
You also have to get the wheel alignment done after the replacement if you have removed the ball joint from the knuckle in order to separate the axle shaft from the hub. This also increases the cost of replacement by $100 to $150. You can reduce this cost by doing the alignment yourself, for which you can refer to the DIY wheel alignment guide. However, in most vehicles, the wheel alignment is unnecessary after replacing the hub assembly.

What Is The Difference Between Front And Rear Hub Assembly?Similar to the front wheel hub assembly, your vehicle has a rear wheel assembly too that allows the rear wheels to rotate freely. Unlike the front hub, rear-wheel hubs, on most cars, are non-driven hubs except for vehicles with rear-wheel drive. Most modern-day cars come with a front-wheel-drive option which makes the rear hubs free from the axle shaft or torque shaft. This makes the replacement of the rear hub assembly much easier than the front ones. While the vehicles with the rear wheel drive option have a similar hub assembly to the front-wheel-drive vehicles, which makes it a little hard to replace them. Like the front hub assembly, the rear hub assembly also houses the wheel bearing, as well as ABS and traction control sensors.

What is a hub in a car?
A hub in a car is a component that connects the wheel to the rest of the vehicle. It is located at the center of the wheel, between the brake drums and the drive axle. The hub has two primary functions: to drive the wheels and to swivel so that the car can be steered. In a front-wheel-drive car, the hub rotates in or next to a large casting called a hub carrier. The carrier itself is mounted to the suspension with ball joints that allow it to swivel and move up and down. The amount the hub carrier can swivel is controlled by the steering gear, to which it is attached by a steering arm with another joint. The hub and drive shaft rotate inside a cast hub carrier which is turned left or right to steer the car. The most common way of transmitting drive from the drive shaft to the hub is by splines grooves machined for a few inches along the end of the shaft which engage with matching grooves inside the hub.
