Service intervals can also be performed yearly rather than every six months. This halves the number of technicians and site visits required for maintenance, while improving turbine uptime – a particularly valuable benefit for offshore wind farms.

Technicians can check for wheel wobble by putting the vehicle on a lift and manually checking for wheel movement. Typically, it would be impossible to shake the wheel and tire. However, if it moves, the hub assembly needs immediate attention. The tire and wheel can literally come off the vehicle at any time, at any speed, if you don’t repair your vehicle.

Driving with bad wheel bearings impacts the safety of a vehicle, and it could cause a serious car accident. We do not advise driving on them when they fail and recommend getting them checked out as soon as possible. Bad wheel bearings can damage things like your hub, the vehicle’s constant velocity joint (CV joint), or the automatic transmission.

The typical sounds of worn-out wheel bearings are squealing and/or growling. The sound intensifies as vehicle speed increases. Try to pinpoint the location of the noise because it will identify the location of the worn-out bearings.

A key performance indicator of the wind energy industry is the so-called LCoE (Levelized Cost of Electricity). It represents the unit-cost of electricity today, considering the full life of the asset. Moreover, it is the basis for the decision to invest or not in a wind farm. The lower the LCoE, the cheaper wind power is compared to fossil energy. Successfully reducing LCoE depends not on manufacturing cheap turbines, but on creating larger turbines with much higher performance. Advanced-technology lubricants can help massive bearings to work reliably with the same precision as the small bearings in an electric motor – contributing to making wind energy more competitive.

In response, Klüber Lubrication has developed a very comprehensive portfolio of high-performance gear oils to accommodate high loads in wind turbine gears. It enables long oil change intervals, has lower power losses and provides higher plant yield – by up to several thousand euros over the service life of a wind turbine. It offers excellent antifoaming characteristics and protection against micropitting. It also contains no additives that might promote residue formation; only those that protect against micropitting, scuffing and white etching cracks (WECs). Due to its high shear stability, the product’s viscosity remains consistent.

Our environmentally-friendly strategy is complemented by our biodegradable products, which exceed current environmental legislation.

The original equipment bearings on your vehicle are engineered for specific loads. Those bigger and wider tires look cool, as do tires with lower tread walls. But they place higher loads on the wheel bearings, possibly resulting in accelerated wear. That could present a safety issue if your wheel bearings fail.

Klüberplex BEM 41-141 meets, and even exceeds, today’s requirements of bearing and wind turbine OEMs and operators. It has excellent false brinelling behaviour for wind turbine applications. The lubricant’s wide service temperature range, its good pumpability and precise metering in centralised lubricating systems as well as good grease distribution and oil release ensure trouble-free operation of the wind power plant.

Klüber Lubrication performs high-quality analyses of both oils and greases for wind applications. We can analyse a customer’s lubricants and advise on contaminants and evidence of bearing wear. We can advise on optimum lubricant quantities, lubrication intervals and lubrication methods. This helps our customers to minimise maintenance costs, especially by detecting potential damage before it occurs.

Wheel bearingreplacement cost

Wheel bearings are theoretically engineered to last the life of the vehicle. There is no maintenance schedule for replacing wheel bearings, and there is no constant source of lubrication. However, they can be damaged, leading to failure.

Badwheel bearingsymptoms

Imagine driving on the freeway when the left front tire and wheel suddenly break off, sending your out-of-control vehicle skidding across several lanes of 65 mph traffic. This is not an exaggeration. This is reality, and can happen if you fail to notice the signs the wheel bearings are deteriorating and need immediate repairs. Your wheel bearing might be bad if you hear unusual sounds like humming, squeaking, or clicking. Some experts say a bad wheel bearing can sound like a bird chirping. Also, if your car wobbles or pulls to one side, you will want to get it checked.

We will keep you informed on news regarding speciality lubricants – on new products as well as on events and trade fairs where you can meet us personally.

Specialty lubricants for wind turbines represent a minor investment but can bring tremendous benefits. Our flushing greases deliver up to 40 per cent less downtime in generators and we offer a universal maintenance grease that’s suitable for all bearings. Our high-performance gear oils offer a good load-carrying capacity and ageing resistance as well as low friction. Furthermore, specialty greases are available for main bearings, blade bearings, generator bearings and yaw bearings.

As wind turbines grow ever larger, their gears are subjected to higher stresses. This can challenge conventional oils’ ability to provide fretting wear protection for ball bearings, resist the formation of micropitting, foam and residues, and ensure viscosity stability.

Our service is particularly valuable because of our extensive experience with wind farm applications, and accuracy in interpreting results.

As a global market leader for wind turbine lubricants, we lubricate the major share of the world’s wind turbines, and could find an optimum solution for you, too.

Sound of wheel bearing failurewhile driving

Hardesty cautions that if you think something is wrong, don’t wait to get it diagnosed: “The longer you wait, the more it will cost as other components may be damaged by a wheel bearing.”

Wind turbines are frequently located in extreme environments whether floating or fixed and are constantly subjected to high loads. Under these harsh conditions gearboxes and bearings face continuous and intense strain, which can have a significant impact on the reliability of the turbines. Trouble-free operation is crucial to wind plant operators, but maintenance is an arduous task and only performed when necessary. For this reason, wind power plant operators need specialty lubricants which perform reliably, protect components and provide extended maintenance intervals.

“The good news is most of the time, a vehicle will let you know way before a failure ever happens,” said Gary Hardesty, Kelley Blue Book’s in-house service and maintenance expert and an A.S.E. certified master technician. “The key is to listen to your car. Most times, a failing wheel bearing will exhibit a growling type of noise that changes with vehicle speed. The faster the car (goes), the faster the frequency of the growl.”

Most vehicles today use sealed hub bearing assemblies that contain roller bearings. While we don’t address these, older cars used tapered roller bearings, which required servicing and preload adjusting to ensure the right amount of end play or axial clearance.

Many turbines complete 20 years or more of service life. Operators could benefit considerably in both continued availability and reduced capital costs if they could run these turbines for another 10 years. Klüber Lubrication specialty lubricants can facilitate this by doubling lubricant lifetime.

Bad wheel bearings can cause the steering wheel to vibrate. The intensity increases as the vehicle speed increases and the vehicle turns to the left or right. However, the vibration could be linked to an out-of-round tire (there could be a flat spot on the tire) or a tire that is no longer balanced. Another cause is damaged or worn suspension components.

If one tire wears out faster than the others, it could be a sign that the wheel bearings are worn. However, it also could be a sign the tire is improperly inflated (too much air pressure or not enough), the tires are improperly aligned, or the vehicle has damaged or worn suspension components.

Wind power plant operators may have inventory issues as many bearing manufacturers recommend different lubricants for each bearing. We developed Klüberplex BEM 41-141, a single lubricating grease for the main, generator, yaw and blade bearings, which outperformed all the other greases compared in standardised tests. This greatly simplifies lubricant purchasing, transport logistics and storage.

The bearings are tightly packed in a grease-filled, waterproof, sealed metal ring. This housing, called a race, is located inside the hub, and each wheel has one. Wheel bearings have a Herculean responsibility: They are engineered to support the vehicle’s entire weight.

If there is excessive play in the steering, meaning the steering seems less responsive or less precise than normal, worn bearings could be causing the problem. Also, this could be a sign the vehicle needs a wheel alignment. If you have any of the signs listed above, visit a dealer service or auto repair shop.

In this story, we’ll tell you quick facts to know, such as what causes a bad wheel bearing, how long you can drive on one, and the estimated replacement cost of a wheel bearing as you maintain your vehicle.

The most easily identifiable and common symptom of bad wheel bearings is audible. But it can be confusing. For example, the source of a humming noise can be linked to other issues, such as tires and the CV joint.

Your vehicle will signal that it’s time to replace a failed wheel bearing. For example, if you hear unusual sounds like humming or clicking, then your bearing might be bad. Watch out and listen for these signs and symptoms:

Worn bearings may cause a vehicle to pull to the left or right when brakes are applied. The direction the vehicle pulls signals where the worn bearings are located, on the left or right side of the vehicle. However, this can also signal brake rotor or brake caliper problems.

Both the demand for energy and the wind resources are distributed around the globe. Therefore, low-emission logistics opens up further potential for wind energy. Klüber Lubrication products, manufactured in many countries around the world, comply with local legislation and help you to save transport costs and CO2 emissions.

The anti-lock warning light may illuminate if the ring, tire, and wheel wobble, the wheel’s speed sensor is no longer operating properly, and the ABS may operate sporadically or not at all. See a professional for repair.

The cost to replace one front-wheel hub assembly varies widely. Among the variables are the vehicle brand and model, the garage’s labor rate, and the cost of parts. The average out-the-door wheel bearing replacement cost without taxes is about $350 per wheel.

The operational demands placed on modern wind turbines are extreme to say the least! Components must continue to operate in all environments, which is why lubricants for wind-turbines play a crucial role. For the smooth operation of wind-turbine power generation plants the selection of the right lubricant is critical to ensure the maintenance of components and reliability of your wind farm.

If you hear a clicking sound that increases in frequency as the vehicle accelerates, there could be a problem with the wheel hub assembly.

Our flushing greases allow bearings to be cleaned during operation, by removing residues while also providing effective lubrication and good protection against fretting wear and corrosion. Bearing life is extended while maintenance downtime is reduced.

Wheel bearings connect a car’s wheels to the axles. They allow wheels to turn with minimal friction. Though wheel bearings are low-maintenance parts, they are important safety components of a vehicle’s braking, steering, and suspension systems. The one-piece hub assembly, between the drive axle and the brake disc or drums, incorporates the hub, wheel bearings, ABS (anti-lock braking system) wheel speed sensor, and mounting flange.
