A worn wheel bearing can cause a howling noise. If you’re also hearing a rumbling noise when turning, then it’s likely a bad wheel bearing.

If you’re still not sure whether the issue lies in the tires or one of the wheel bearings, check out the most common symptoms of each issue:

What do you do when a customer brings you a vehicle with a roaring or howling noise coming from a wheel? In most cases, it can be coming from a worn tire, or a worn bearing. It is not easy to tell, but there are ways to determine what is causing the problem.

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.

The noise may be the result of an under-inflated tire or improperly aligned tires. These issues cause part of the tires (or one tire) to be scrubbing on the pavement. That causes a squealing noise.

If the problem is a worn wheel bearing, then you’re hearing a knocking noise because the bearing isn’t rotating as freely as it should. A bad tire can cause a knocking or thumping noise, too. To be more specific:

If you’re hearing this noise, the issue may be a bad wheel bearing. To confirm it, change the speed of the vehicle. If the noise becomes worse the faster you drive, then it’s almost certainly a bad wheel bearing. If the noise remains the same, then the issue may be the tires instead.

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.

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.

In extreme cases, a failed wheel bearing can cause abnormal tire wear. When that happens, the noise you’re hearing is caused by both a bad wheel bearing and a worn tire.

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.

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.

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.

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.

You may also trace this noise to a loose pinion-bearing preload. It’s likely the case when you only hear the noise when decelerating.

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.

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.

If the issue is a worn wheel bearing, you’d typically hear this noise while cornering or making sharp turns with moderate speed. A bad CV joint can be heard at low speeds with the steering wheel all the way to one side or the other. It can’t hurt to check both the wheel bearings and CV joint(s).

If you’re replacing a bad wheel hub bearing, you want to make sure that your techs use high quality replacement parts. Using high quality replacement parts:

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.

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.

The best way to figure out the cause of this noise is to check the tires first. If the tires look good, then check the wheel bearings.

It can be hard to figure out if the noise is caused by a wheel bearing or a tire. There’s something you can try, though. Turn the steering wheel slightly to the left or right. If the noise gets worse, then it’s likely one of the wheel bearings.

If the noise is more “growly”, then the issue is likely a bad wheel bearing. The noise may become louder the faster you drive.

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.

If the wheel bearing and tires look good, you may want to check the drivetrain. Sometimes a humming or growling noise is a sign of an issue within the drivetrain.

We put together this noise guide to save you some labor time. You can have your technicians find the noise that best describes what they’re hearing in the list below. From there, they may be able to figure out what the issue is.

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.
