Wheel Hub Assembly Guide: Everything You Need to Know


The wheel hub assembly holds significant importance within a vehicle's suspension system, crucial for a safe and smooth driving experience by allowing the wheel to rotate freely. It comprises essential elements such as the wheel hub, bearings, mountings, and occasionally, anti-lock brake system (ABS) sensors.


Key Components Involved in a Wheel Hub Assembly


The wheel hub assembly comprises various essential elements:

1. The wheel hub, serving as the attachment point for the wheel and tire.

2. Bearings, facilitating smooth wheel rotation with minimal friction.

3. Mountings, ensuring the secure attachment of the hub assembly to the vehicle.

4. ABS sensors, monitoring wheel speed and aiding in the effective operation of the car's ABS system.


Signs of a Bad Wheel Hub Assembly 


Identifying the initial symptoms of a deteriorating wheel hub assembly can prevent unforeseen breakdowns. These warning signs comprise:

Abnormal Sounds: Abnormal sounds like humming, rumbling, or growling noises emanating from the tire or wheel region, particularly if they amplify in intensity as the vehicle accelerates.

Loose or Woobly Steering: Loose or unsteady steering, potentially stemming from a compromised wheel hub assembly that impacts steering control.

Malfunctioning ABS System: Malfunctioning ABS system, is noticeable through the activation of the ABS warning light.

Uneven Tire Wear: Uneven tire wear, which can result from various factors including a failing wheel hub assembly.


Cost to Replace a Hub Assembly


The price of replacing a wheel hub assembly can vary significantly based on factors such as your vehicle's make, model, and production year, and whether you opt for original equipment manufacturer (OEM) or aftermarket parts. Typically, the cost ranges from $200 to $500 per hub assembly, covering both parts and labor. However, luxury vehicles and specific models may incur higher expenses.


Can You Drive with a Bad Hub Assembly?


Operating a vehicle with a deteriorating or faulty hub assembly not only jeopardizes your safety but also increases the likelihood of additional harm to your vehicle. A severely compromised hub assembly can escalate the risk of the wheel detaching from the vehicle or seizing up, potentially leading to a loss of control over the vehicle and posing a serious safety hazard on the road. It's crucial to address any issues with your hub assembly promptly to mitigate these risks and ensure the overall well-being of both you and your vehicle.


What Happens When a Wheel Hub Assembly Fails?


A malfunctioning wheel hub assembly undermines your vehicle's stability and its capacity to grip the road securely. This can result in heightened vibration, compromised handling, and in severe instances, complete wheel detachment or the wheel's inability to rotate altogether.


Should I Replace the Whole Hub or Just the Wheel Bearing?


In numerous contemporary vehicles, the wheel bearing is incorporated within the hub assembly, requiring the replacement of the entire unit should the bearing malfunction. Nevertheless, if your vehicle features a hub assembly that allows for independent bearing replacement, you may solely need to replace the bearing. This choice largely hinges on your vehicle's hub assembly design and the severity of damage or wear.




The wheel hub assembly plays a crucial role in your vehicle's performance and safety. Regular maintenance, timely inspections, and early intervention upon detecting signs of wear are essential steps to prevent extensive damage and maintain a seamless driving experience. If you suspect any issues or the need for replacement with your wheel hub assembly, it's advisable to consult a professional mechanic promptly. This component is vital for your vehicle's functionality and overall safety while driving.
