You find abs hub bearings at the center of your wheel hub assembly. These parts help your wheels spin smoothly and support the weight of your car. The hub bearing sits inside the wheel hub assembly, which connects the wheel to the axle. When you drive, the bearing lets the wheel turn with little friction. This helps your car move safely and keeps the ride quiet.
If you choose the wrong abs hub bearings, you risk problems with your wheels and brakes. You might hear grinding or growling noises from the wheels. Sometimes, you feel vibrations in the steering wheel or the car body. Uneven tire wear can also happen. In some cases, the wheel may feel loose or wobbly. You might even notice a burning smell near the wheels. These signs mean you need to check your wheel hub assembly and replace the bearing if needed.
Tip: Always check your wheel hub assembly for damage if you notice any of these warning signs. Early action can prevent bigger problems.
The ABS sensor sits inside the wheel hub assembly. It plays a key role in your car’s anti-lock braking system. The sensor tracks how fast each wheel spins. It does this by watching the teeth on a reluctor ring as the wheel turns. The sensor sends this information to the car’s computer, called the Electronic Control Unit (ECU).
The sensor helps the ECU know the speed and direction of each wheel.
If a wheel starts to lock up during braking, the sensor alerts the ECU.
The ECU then tells the brakes to pump quickly, which stops the wheel from skidding.
This process helps you keep control of your car, especially in slippery conditions.
Choosing the correct abs hub bearings and wheel hub assembly keeps your ABS working right. This means better safety and smoother driving every day.
You need to start by identifying the type of wheel bearing your vehicle uses. This step helps you avoid mistakes and ensures your car stays safe on the road. Here is a simple way to find the right information:
Check your owner's manual or visit the manufacturer's website for your car's specifications.
Learn about the types of wheel bearings, such as ball bearings and tapered roller bearings.
Measure the dimensions and clearances of your wheel bearing. Make sure they match the numbers given by the manufacturer.
Look for OE (Original Equipment) or OEM (Original Equipment Manufacturer) specifications. These numbers guarantee the part will fit and work correctly.
You will find three main types of wheel bearings in vehicles with ABS systems. The table below shows their differences:
| Type of Bearing | Description |
|---|---|
| Ball Bearings | Versatile and common, suitable for smaller vehicles, handling both radial and thrust loads. |
| Tapered Roller Bearings | Designed for heavy loads, ideal for trucks and performance cars due to their cone-like shape. |
| Hub Bearings | Sealed units that combine the bearing and hub, maintenance-free and easy to install in new cars. |
Tip: Always match the bearing type to your vehicle’s needs. Using the wrong type can lead to a bad wheel hub assembly or even a failing wheel hub assembly.
The wheel hub assembly connects your wheel to the axle and holds the wheel bearing. You need to know the features of your assembly to choose the right replacement. Some cars use ABS hub bearings, while others use non-ABS types. The table below highlights the main differences:
| Feature | ABS Hub Assemblies | Non-ABS Hub Assemblies |
|---|---|---|
| Part Numbers | Different for front and rear hubs | Different for front and rear hubs |
| Magnetic Pickup Feature | Present in ABS bearings | Not present in non-ABS bearings |
| Size of Bearings | May differ due to ABS requirements | Standard sizes without ABS features |
ABS hub bearings include a magnetic pickup feature. This part works with the anti-lock braking system. Non-ABS hub assemblies do not have this feature. If you install the wrong assembly, your ABS sensor may not work. This can cause problems with your brakes.
Some vehicle manufacturers use special bearing numbers for their models. For example:
| Bearing Number | Vehicle Type | Dimensions (mm) | Bearing Type |
|---|---|---|---|
| DAC428039 ABS | RENAULT DUSTER ABS, FLUENCE | 42 x 80 x 39 | Angular Contact Ball Bearing |
| OEM Numbers | 402 108022R, 402 106371R |
Always check the part number and dimensions before buying a new wheel hub assembly.
You must check if your new wheel hub assembly is compatible with your car’s ABS system. Here are some steps you can follow:
Look for a small magnetic plate inside the inner seal lip of the bearing. This plate is crucial for ABS compatibility.
Find the magnetic tone wheel. It looks like a seal but contains a series of small magnets. This part is essential for the ABS sensor to work.
Use a small screwdriver to test the magnetization of the ring on the back of the bearing. If it attracts iron filings, the bearing is likely compatible with ABS.
If you install a non-ABS bearing in a car that uses an anti-lock braking system, you risk several problems:
The ABS system may not work because non-ABS bearings lack the magnet needed for the sensor.
The ABS sensor may fail, leading to brake issues.
The absence of the magnet in non-ABS bearings is a key difference that affects the operation of your ABS.
Note: Always double-check for the magnetic feature before installing a new wheel hub assembly. This step helps you avoid costly mistakes and keeps your ABS system working as it should.
You need to prepare before removing the wheel bearing. Gather your tools and make sure you have a safe workspace. Use a jack and jack stands to lift your car. Wear gloves and safety glasses to protect yourself. You do not need to remove the ABS sensor to replace the wheel bearing, but you should work carefully around it.
Use a socket set and wrenches to remove the wheel and brake caliper.
Take off the rotor to reach the wheel hub assembly.
Loosen the bolts that hold the wheel hub assembly to the knuckle assembly.
Gently pull the wheel hub assembly away from the mounting surface.
Avoid damaging the ABS sensor, connectors, or wires during this process.
If you need to remove the knuckle, mark its position for easier mounting the knuckle later. Take your time and avoid using too much force.
Start by cleaning the area where you will place the new wheel bearing. Make sure the surfaces are free from dirt and rust. Place the new wheel bearing into the wheel hub assembly. Align it with the bolt holes and secure it with the correct fasteners. Use a torque wrench to tighten the bolts to the manufacturer’s specifications. This step helps prevent future problems.
When installing the new wheel bearing, check that the ABS sensor sits in the right spot. Do not handle the assembly by the speed sensor cable. Reinstall the rotor and brake caliper. Put the wheel back on and lower the car safely.
You can avoid many common mistakes by following best practices. The table below shows what you should do and what you should avoid:
| Dos | Don'ts |
|---|---|
| Validate replacement parts | Damage wheel speed sensors, connectors or wires |
| Clean mating surfaces to ensure proper fitment | Heat up the knuckle or hub with a torch |
| Utilize the proper tools for the job | Use pneumatic or electric impact wrenches |
| Torque all fasteners to spec | Damage surrounding areas when removing the old part |
| Apply anti-seize only to appropriate surfaces | Handle the assembly by the speed sensor cable |
| Use excessive force to remove the old hub | |
| Pry or chisel a hub away from the knuckle (Use a rotational force to break galvanic corrosion instead). |
Tip: Always use the right tools and follow the instructions for your vehicle. This helps you keep your ABS system working and your car safe.
You need to handle the ABS sensor with care during any wheel bearing replacement. Many people accidentally damage the sensor by pressing the bearing in the wrong direction. This mistake can cause the ABS sensor to stop working. If your vehicle uses a tone ring attached to the wheel bearing, improper installation can change the air gap. This small change can lead to sensor problems. When the sensor does not work, your ABS warning light may turn on. You might lose important safety features. Always check the sensor and tone ring before and after installation.
Tip: Take your time and follow the correct steps. Protect the sensor and wires from bumps or pinches.
Choosing the wrong part often leads to a bad wheel hub assembly. If you install a bearing that does not match your car’s make and model, you risk poor performance. The wheel may wobble or make noise. You might notice uneven tire wear or even a burning smell. A failing wheel hub assembly can cause your ABS system to stop working. This puts your safety at risk. Always double-check the part number and size before you start the job.
Low-quality ABS hub bearings can cause many problems for your vehicle. You may see these issues:
The bearing may fail early, which can lead to wheel lock-up or even the wheel coming off while you drive.
Cheap bearings often cannot handle the stress of daily driving. This can wear out other parts and force you to repair your car more often.
Ignoring a bad bearing can lead to bigger problems, like unsafe driving and costly repairs.
Environmental factors also affect how long your bearings last. High temperatures can make the lubricant less effective, which may cause the bearing to fail. Moisture and road salt can lead to rust and corrosion. Some materials, like stainless steel, resist corrosion better, but special alloys work even better against salt.
