When bearings are damaged and making noise, it’s hard to diagnose because you have to drive the vehicle in order to reproduce the sound. Here are tips to help you find the source of the problem:

6. Activation zoneThe activation zone is used to activate and set-up the system in combination with the magnetic cap. The settings can easily be changed any time. The delivered amount of lubricant varies on the selected month settings.

Wheel bearings are essential in the operation of your vehicle. More precisely, a wheel bearing is crucial for the proper function of the hub, tire and wheel assemblies to work together. The wheel bearing allows friction-free movement and rotation of the hub assembly, and thereby provides smooth tire and wheel rotation. When the wheel bearing goes bad, you will notice several symptoms.

3. Grease cartridgeThe cartridge version of the BEKA ONE is equipped with a 120 ml grease cartridge. You can easily replace the cartridge when it’s empty and be assured that the right grease is used without any contaminations.

Wheel bearingnoise when accelerating

While driving down the road about 40 mph, sway the car side to side slowly, shifting the weight of the vehicle from one side to the other. Do not drive crazy or cause the car to spin out, just sway it gently. Notice whether the noise gets louder or softer. If the noise is a little less if you turn right, the damaged bearing may be on the left, or vice versa.

Listen carefully. The most common and often most-identifiable symptom associated with a bad wheel bearing is noise coming from the wheel or tire area of the moving vehicle. You may mistake this as engine noise, but when you listen closely you are likely to hear grinding or grating that gets louder as the vehicle accelerates. Since wheel bearings are not known for wearing out that frequently, the noise is typically suspected to be something else and the problem overlooked.

Most wheel bearings are hardened steel and can withstand a lot of abuse. Its two worst enemies are heat and water. Heat caused by lack of lubrication can destroy a wheel bearing. Water that penetrates a sealed bearing will also destroy it.

1. Magnetic capThe magnetic cap is the key component of the BEKA ONE. With this cap you can set the operation time of the system, or power the system on and off without contaminating the pumps inside.

5. BatteriesThe BEKA ONE is driven by two 1.5V AA-batteries which are safely covered and replaceable when low on power. There’s no special battery pack needed, you can use standard batteries. To achieve functionality at a certain pressure and below a certain temperature, it’s recommended to use Lithium-ion batteries.

Groeneveld-BEKA systems and services reduce operational costs for customers, while increasing equipment uptime, productivity, efficiency and safety: this is what it is all about at Groeneveld-BEKA.

When the seal on the wheel bearing is broken or damaged, the noise starts out very faint and becomes louder over time. It sounds like the noise that your tires make when hitting a rumble strip on the highway, just not quite as loud, something like the sound of playing cards flapping against bicycle spokes.

How to fixbad wheel bearing

The BEKA ONE is an electromechanical lubricator designed to supply lubricant to single lubrication points. The BEKA ONE is the ideal solution to supply lubricant in a safe, precise and reliable way where an automatic lubrication system is too large or too complex.

Are you doing the steering, or is the car driving where it wants to? When a wheel bearing corrodes or becomes pitted, the smooth exterior lining is gone and the vibration is transmitted to the tires which may feel like it is “pulling” to one side or the other.

8. OutletThe BEKA ONE has a metal outlet thread to mount the system directly on a lubrication point. If necessary an adapter can be used. Remote mounting of the system with a polyamide tube is also possible.

The BEKA ONE ensures reliable lubrication for 1 up to 24 months per filling. The best part is, the system can be refilled as often as needed. Due to the exchangeable batteries, there’s a one-time acquisition for the BEKA ONE.

Chances are when you start hearing a loud noise from under the hood of your car as you drive, you automatically think it’s an exhaust leak or your car is going to break at any moment. But have you thought about the possibility of a broken — or nearly broken — wheel bearing causing that noise?

7. Indication LEDsBright LEDs indicate the system operation. Green LEDs show the remaining lubrication cycles for the filling, while a bright red LED starts flashing when an error occurs or the batteries are running low. The LEDs also indicate the backpressure of the system after each lubrication cycle.

Reducing customers’ operational costs and at the same time increasing uptime, productivity, efficiency and safety of their vehicles and machines. That is what it’s all about at Groeneveld-BEKA.

Note that tires that are “chopped” or “scalloped” (worn in patches) also make a rhythmic noise that increases in speed. This sounds very similar to a bad wheel bearing. Look at your tires as well if you hear this kind of noise.

2. Protective coverThe BEKA ONE has a protective cover to make sure the system is protected from dirt, dust and liquids. Due to the IP-rating of the system, you don’t have to worry about cleaning with a high pressure washer.

There are two versions of the BEKA ONE, one with a grease cartridge and one with a refillable reservoir. Whether you need to lubricate with oil or grease, the BEKA ONE can do it. It’s an environmental friendly and economical solution, easy to install wherever lubrication is necessary.

Does your car feel loose? When you hear professional drivers talk about a “loose” car, you may not know what that means. It often refers to the steering of the vehicle, which can include wheel bearings. Wheel looseness, or also called wheel play, is another common symptom of a bad wheel bearing. As the bearing begins to wear down, they become loose inside the wheel hub and spindle, which makes your vehicle feel loose while steering.

What about your tires? We all know the importance of rotating your tires to promote even wear, but did you know a broken wheel bearing can lead to uneven tire wear too? The looseness of the wheel and the vibration that reverberates through the wheel causes your tyres to wear unevenly, meaning you are more likely to have to invest in new tyres sooner.

Most wheel bearings manufactured today are sealed. They come from the factory pressed together as an assembly: front race, bearing set, centre race, bearing set, and outer race, with seals on both the front and rear. Seals protect bearings from the elements, water, and debris, and they also seal in the high-temperature grease the bearing needs. When a seal is broken or damaged, the wheel bearing will fail and start making noise.

4. Lubricant reservoirThe refillable version of the BEKA ONE is equipped with a 120 ml reservoir, suitable for oil and grease. The reservoir can easily and quickly be refilled with a grease gun or oil press, using the grease fitting. Replacement of the reservoir is not necessary. Because the grease fitting is located behind the cover it’s protected from dirt, dust and liquids, preventing contamination of the lubricant during refilling.
