A worn wheel hub bearing can cause humming, grinding, vibration, or wheel play. Replacing it early can help prevent further damage and keep your vehicle safe on the road.
This guide explains how to replace a wheel hub bearing step by step. The process can vary by vehicle, but the basic procedure is similar for many cars and light trucks.
What Is a Wheel Hub Bearing?
A wheel hub bearing supports the wheel and allows it to rotate smoothly. On many modern vehicles, the bearing is built into the wheel hub assembly. When the bearing wears out, it can affect wheel movement and create noticeable noise while driving. Some vehicles use a separate bearing and hub, while others use a complete hub bearing assembly that bolts directly to the steering knuckle or rear suspension.
Signs of a Bad Wheel Hub Bearing
Before replacing a wheel hub bearing, check for common symptoms.
- Humming or growling noise while driving
- Grinding sound from the wheel area
- Wheel vibration at certain speeds
- Excessive wheel play
- Uneven tire wear
- ABS warning light on some vehicles
- Noise that changes when turning
A bad bearing can sound similar to tire noise or other suspension problems. Inspect the wheel, tire, suspension, and bearing before buying replacement parts.
Tools and Parts You May Need
The exact tools depend on the vehicle and bearing design. Common tools include:
- Floor jack
- Jack stands
- Wheel chocks
- Lug wrench
- Socket set
- Ratchet or breaker bar
- Torque wrench
- Screwdrivers
- Pliers
- Wire brush
- Penetrating oil
- Hammer
- Pry bar
- New wheel hub bearing assembly
Some vehicles require a hydraulic press if the bearing is pressed into the steering knuckle. A replacement hub assembly usually requires fewer specialized tools.
Safety First
Park the vehicle on a flat, solid surface and engage the parking brake, and place wheel chocks behind the wheels that remain on the ground. Never rely on a floor jack alone to support the vehicle — use properly rated jack stands before working underneath or around the wheel. Wear safety glasses and gloves during removal and installation. If you are not comfortable working with brakes, suspension parts, or heavy components, have a qualified mechanic perform the repair.
How to Replace a Wheel Hub Bearing
1. Confirm the Correct Replacement Bearing
Check your vehicle's year, make, model, engine, and drivetrain before ordering a replacement. Some vehicles use different hub assemblies on the front and rear, and ABS-equipped models may also require a hub with an integrated wheel speed sensor. Compare the new part with the original before installation, checking the mounting points, connector, bolt pattern, and overall design.
2. Loosen the Lug Nuts
Park the vehicle and secure it with wheel chocks. Before lifting the vehicle, loosen the lug nuts slightly with a lug wrench. Do not remove them completely while the tire is still on the ground.
3. Raise and Support the Vehicle
Position the floor jack under the vehicle's recommended lifting point and raise the vehicle until the tire clears the ground. Place a jack stand under an approved support point, then slowly lower the vehicle onto the stand. Give the vehicle a gentle check to make sure it is stable before continuing.
4. Remove the Wheel
Remove the loosened lug nuts and take off the wheel, then set the wheel aside in a safe location. You should now have clear access to the brake and hub assembly.
5. Remove the Brake Components
The brake setup varies between vehicles. For many disc-brake systems, you will need to remove the brake caliper and caliper bracket to access the hub. Support the caliper with a suitable hook or wire do not let it hang from the brake hose. Remove the brake rotor if it blocks access to the hub assembly, and keep track of the bolts and hardware during removal.
6. Disconnect the ABS Sensor
If the vehicle has an ABS wheel speed sensor connected to the hub, locate its electrical connector and disconnect it carefully. Remove any clips or retaining bolts holding the wiring in place. Avoid pulling or twisting the sensor wire, as damaging the wiring can create an ABS fault after the repair.
7. Remove the Old Wheel Hub Bearing
Locate the hub mounting bolts behind the steering knuckle or suspension assembly. Apply penetrating oil if the bolts or hub are heavily corroded, then remove the mounting bolts using the correct socket and breaker bar. Once the bolts are removed, pull the hub assembly away from the vehicle. A corroded hub can be difficult to remove light tapping with a suitable hammer may help loosen it. Avoid damaging the steering knuckle, axle, brake components, or ABS wiring.
8. Clean the Mounting Surface
Before installing the new hub, clean the mounting surface. Use a wire brush to remove rust, dirt, and corrosion from the mating surface, since a clean surface helps the new hub sit correctly against the knuckle. Do not leave heavy rust or debris between the hub and mounting surface.
9. Install the New Wheel Hub Bearing
Position the new hub assembly in the correct orientation and install the mounting bolts by hand first. Make sure the hub sits flat against the mounting surface, then tighten the bolts gradually in the correct sequence. Use the vehicle manufacturer's torque specifications for the hub bolts do not guess the torque value, as incorrect torque can cause premature bearing failure or loose mounting hardware.
10. Reconnect the ABS Sensor
Reconnect the ABS sensor and secure the wiring in its original position, making sure the wire is away from the tire, brake rotor, and other moving parts. If the new hub has an integrated ABS sensor, verify that the connector is fully seated.
11. Reinstall the Brake Components
Reinstall the brake rotor if it was removed, then install the caliper bracket and brake caliper. Tighten all fasteners to the manufacturer's specified torque, and make sure the brake hose is not twisted or stretched.
12. Reinstall the Wheel
Place the wheel onto the hub and install the lug nuts by hand, tightening them evenly. Lower the vehicle until the tire touches the ground enough to prevent it from turning, then tighten the lug nuts using a torque wrench, following the manufacturer's recommended lug nut torque specification.
13. Check the New Wheel Hub Bearing
Before driving, check the wheel for unusual movement. Spin the wheel by hand and listen for abnormal grinding or roughness. If the vehicle uses an ABS sensor, make sure the warning light is not staying on after startup. Take a short test drive at low speed first, listening for unusual humming, grinding, clicking, or vibration.
What If the Bearing Is Pressed Into the Hub?
Not every vehicle uses a bolt-on hub assembly. Some vehicles have a separate wheel bearing pressed into the steering knuckle. Replacing this type usually requires additional steps and a hydraulic press the old bearing must be pressed out, and the new bearing must be pressed in correctly. Do not hammer directly on the bearing race unless the manufacturer's procedure specifically allows it, since incorrect pressing can damage the new bearing before the vehicle even reaches the road. For press-in bearings, professional installation may be the safer option if you do not have the required equipment.
Common Wheel Hub Bearing Replacement Mistakes
Avoid these common errors during the repair:
Using the Wrong Hub Assembly
A similar-looking hub does not guarantee compatibility. Verify the exact part number for your vehicle.
Incorrect Torque
Over-tightening or under-tightening fasteners can cause problems. Always use factory torque specifications.
Damaging the ABS Sensor
The sensor and wiring can be fragile. Handle them carefully during removal and installation.
Reusing Damaged Hardware
Inspect bolts, clips, and other hardware before reusing them. Replace any parts that are damaged or specified as single-use.
Skipping the Mounting Surface Cleaning
Rust and debris can prevent the hub from sitting flat. Clean the surface before installation.
Forgetting the Brake Check
After reinstalling the brake components, make sure everything is secure before driving.
