Replace Wheel Bearing or Entire Hub: A Comprehensive Guide

When your vehicle's wheel bearing goes bad, you'll start to hear a humming or grinding noise coming from the wheel. This noise will get louder and more frequent as the bearing wears down, and it can eventually lead to the wheel coming off of the car. If you hear this noise, it's important to have your wheel bearing replaced as soon as possible.

Wheel Bearing vs. Hub Assembly

Wheel bearings are an important part of your vehicle's suspension system. They allow the wheels to rotate smoothly and freely, and they help to reduce friction between the moving parts. Most modern vehicles have sealed wheel bearings which are integrated into the hub assembly. The hub assembly is a larger unit that includes the wheel bearing, the brake rotor, and the wheel studs.

In some cases, it may be necessary to replace the entire hub assembly instead of just the wheel bearing. This is typically the case if the hub assembly is damaged or if the wheel bearing is not easily accessible.

Signs of a Bad Wheel Bearing

There are several signs that can indicate a bad wheel bearing, including:

• A humming or grinding noise coming from the wheel
• Increased noise when turning or braking
• Vibration in the steering wheel or seat
• Play in the wheel when it is shaken
• Uneven tire wear

Causes of Wheel Bearing Failure

Wheel bearings can fail for a variety of reasons, including:

• Wear and tear: Wheel bearings are subject to a lot of stress and wear, and they can eventually fail due to normal use.
• Lack of lubrication: Wheel bearings need to be properly lubricated in order to function properly. If the bearings are not lubricated properly, they can overheat and fail.
• Damage: Wheel bearings can be damaged by impact, such as hitting a pothole or curb. This damage can lead to the bearings failing prematurely.

Is It Better to Replace the Wheel Bearing or the Entire Hub Assembly?

In most cases, it is more cost-effective to replace the entire hub assembly instead of just the wheel bearing. This is because the hub assembly is a sealed unit, and it is difficult to replace just the wheel bearing. Additionally, replacing the entire hub assembly will ensure that all of the components are new and in good condition.

How to Replace a Wheel Bearing or Hub Assembly

Replacing a wheel bearing or hub assembly is a job that is best left to a professional mechanic. However, if you are confident in your abilities, you can follow these steps to replace the bearing or hub assembly yourself:

1. Gather your tools and materials. You will need a jack, jack stands, a socket wrench, a torque wrench, and a new wheel bearing or hub assembly.
2. Raise the vehicle and secure it on jack stands. Make sure that the vehicle is level and stable before you begin working on it.
3. Remove the wheel. Use a socket wrench to loosen the lug nuts, and then remove the wheel.
4. Remove the brake caliper. Use a socket wrench to loosen the bolts that hold the brake caliper in place, and then remove the caliper.
5. Remove the hub assembly. Use a socket wrench to loosen the bolts that hold the hub assembly in place, and then remove the assembly.
6. Install the new hub assembly or wheel bearing. Apply a thin layer of grease to the new bearing or assembly, and then install it in place. Tighten the bolts that hold the bearing or assembly in place.
7. Reinstall the brake caliper. Use a socket wrench to tighten the bolts that hold the brake caliper in place.
8. Install the wheel. Use a socket wrench to tighten the lug nuts.
