The wheel hub - the part that the wheel bolts to - is held in place by the hub-nut, which prevents the wheel and hub from coming off the axle.

Wheel bearings are considered a standard wear and tear item on a car. Depending on the number of miles you drive and how long you keep a car, you should expect to have to replace them at some point.

Modern wheel bearings are often made into modular units that bolt on and off the car for easy maintenance. Older cars, and some new ones, require powerful hydraulic presses to force out the old bearings and ‘press in’ the new ones.

If you hear an unfamiliar noise when drifting to the left, there may be a problem with your right wheel bearing. If the noise occurs when you drift right, the left wheel bearing may be faulty.

Lincoln Automatic Hammer Grease Pump This unique Automatic Hammer Grease Pump protects your Critical Breakers / Hammers. The pump attaches directly to your hammer, gripper or crusher and is connected to the hydraulic power supplier of the carrier. Your operator, with the push of a pedal, automatically sends a single shot of grease to lubricate the bearing points. When the operator’s foot comes off the pedal and hydraulic fluid pressure is removed from the hammer, the drop in pressure releases the spring in the pump and recharges it so it is ready to lubricate again the next time the device is activated. Installed directly on the hammer, the pump travels with your hammer, not your machine.

You can estimate your wheel bearing cost depending on the type you buy. Here’s a quick overview of the different price brackets:

Not only can this cause a wayward steering feel, but it can also wear out your front tyres faster. If your car feels like this when steering and shows other signs of a worn bearing, get it checked as soon as possible.

Bearing failure resulting from improper greasing is a major cause of equipment downtime and significant unnecessary maintenance costs to major construction, road building, aggregate, forestry and mining companies. The majority of failures are caused by: contamination of bushings by dust, dirt and moisture; inadequate amounts of grease applied to bearings; or over-greasing of key pivot points.

Auto lube systems for heavy equipment

Be careful when touching any part of the wheels as they can become very hot depending on the severity of the bearing issue and if you have been braking hard. But if one wheel is slightly warmer, this could indicate a bearing problem.

Direct costs resulting from inadequate greasing can include: replacement bearings; labor to repair or replace bearings; lost time and its impact on productivity. Indirect, but very real costs of inadequate greasing include: wasted grease, environmental issues, safety or housekeeping issues, and higher labour costs related to inefficient manual greasing practices.

FLO Greasing Systems are designed for the extreme weather conditions and severe job requirements often faced in Canada, using components from Lincoln Lubrication. Completely reliable and fully automatic, a FLO System will increase your component life and overall productivity.

While a mechanic will be best placed to properly diagnose your wheel bearing issues, there are some symptoms to look out for. Here are four signs drivers need to know:

As bearings wear, they create more noise. The noise from a wheel bearing will be a constant droning or scraping noise and is the best way to tell if there is a problem.

Bearings are absolutely everywhere in machinery and vehicles. Anything with moving parts will always have a bearing of some kind. Car wheels require strong and precise bearings to cope with the large forces of bumps and turns.

However, life expectancy depends on how often you drive and the condition of the roads you drive on. This may mean wheel bearings need replacing sooner or later, but they won’t need replacing regularly.

Asphalt Silo Gate Automatic Greasers At an asphalt plant, a truck drives underneath the silo so hot asphalt can be deposited into the truck body, and then trucked to where the Paving crew is laying it down. The silo has a door or “gate” at the bottom, which has to be able to open and close repeatedly as the Plant fills the trucks. The hinges or bearings on these gates must be properly lubricated, because a seized gate can be catastrophic. The FLO Silo Gate Automatic Greaser lubricates the four main points of the gate and helps to eliminate the seized gate scenario. For more information, see our Silo Gate Autogreasing Systems Solutions page.

Wheel bearings are a small yet mighty part of your car vital to movement and safety. If they’re not functioning properly, you must replace them immediately.

Obviously, this is an extremely dangerous situation. It can cause a complete loss of control and a high chance of injury.

This can start to happen because the wheel bearing ensures the wheels are rotating in a single plane and not moving side to side when the bearing wears out.

The traditional construction of a bearing is two rings, called races, and small balls. When assembled the balls transmit the load between the inner and outer races whilst allowing rotation and retaining their position laterally (side to side).

When doing an MOT, the tester will lift your car and firmly pull on the wheels in various directions. Excess movement in the wheel, when pulled from the top or bottom, is usually a symptom of a failing wheel bearing.

Because a bearing's job is to reduce friction, when they’re not working as they should, more friction and therefore heat is generated. This can often be felt on the wheel after a long drive.

Whilst wheel bearings can take a while to get to the replacement point, it’s still important to have the bearing checked as soon as you notice a new noise or feel any symptoms. Hopefully, this guide has introduced you to wheel bearing replacement costs and answered some questions you may have had. When in doubt, consult a professional mechanic or work with a garage to achieve a safe solution.

If you can hear a new noise, particularly a droning that increases in volume and frequency with speed, there's a good chance you have a failing wheel bearing.

Another determining factor is when the noise is present; if, when braking, the noise gets louder, this usually means that one of the front bearings is worn out. This is because the action of the weight of the car shifts more to the front wheels when decelerating.

Wire Rope Lubrication System This system replaces manual cleaning and lubrication of wire ropes. Using your Wire Rope Lube System, the old lubricant and grit are mechanically scraped from the grooves and surfaces of the wire ropes. Simultaneously, new lubricant is uniformly applied to the cleaned wire rope surface and injected into the inner core of the wire. The new lubricant reduces wear between individual strands of wire by replacing the trapped moisture in the wire rope. This eliminates a major cause of corrosion. The system will help provide you peace of mind in the safe operation of your wire rope and extends its working life.

When a bearing completely fails, the hub nut can no longer stop the outer bearing race, hub and wheel from sliding off the axle. In short, the wheel can literally fall off the car.

Because they support the road wheels, wheel bearing noise depends on speed. If you notice a noise that stays the same volume and pitch when doing 30mph or 70mph, it’s probably not a wheel bearing.

So, if you’re wondering if wheel bearings are expensive, the price ultimately comes down to which specific parts your car needs.

The Autogreaser dispenses small measured amounts of grease at frequent intervals while your equipment is operating, maintaining a consistent grease seal to prevent dirt and contaminants from migrating into your bearings. It will help keep your loaders, pavers, excavators, graders, mining and other heavy equipment out on the job and reduce your labor costs when compared to the traditional method of point-by-point manual greasing.

Joseph has been writing about cars for over seven years and writing for Bumper for over two, blending his passion for automobiles with a talent for storytelling.

If it's too difficult to tell, especially with how well sound-insulated modern cars are, a passenger can try listening to the noise from the front and then rear seats.

However, determining which one is at fault takes a little more investigation. See below for instructions on how to examine wheel bearing problems.

Wheel bearing replacement is a common issue, so the parts are relatively cheap, and any competent garage well understands the process. Typical parts prices range from £30 to £250, but then you have to include the labour costs as well.

Typically it is cheaper to replace a bearing on a non-driven axle, as there are fewer components to remove, with most cars being front-wheel drive (except for many BMW and Mercedes cars) this means the rear bearings are cheaper.

Now you’ve figured out roughly where the offending bearing is, it should be pretty easy to determine which side is at fault:

Not sure what to look at, or hear for when they might need replacing? Worried about the cost of wheel bearings? Or simply want to understand a bit more about how wheel bearings work?
