With the wheel bearing replacement cost in mind, you may be wondering if you can drive with a bad wheel bearing. A bad wheel bearing needs to be changed as soon as possible. There is no lubrication on a bad wheel bearing. Consequently, as you drive with a bad wheel bearing, you run the risk of the wheel bearing completely failing and breaking apart, which can cause massive stability problems when driving, even a crash. If you’re in the middle of nowhere and you need to drive a short way to get help to prevent this scenario, you should drive at a slower speed so that your wheel remains intact for a couple more hours.

There are many different varieties of production system, each of which has its own advantages and disadvantages. MinebeaMitsumi decided to introduce this vertically integrated manufacturing system so that it could focus uncompromisingly on its pursuit of ultra precision and ensure a steady supply of its products as a bearings manufacturer. All aspects of production, from design and development to the manufacture of each component, the production of jigs and tools to make those components, right through to the assembly of components, are performed in-house. It is thanks to this system that MinebeaMitsumi has been able to achieve its ultra-precision machining and mass production technologies. Every single process in the manufacture of ball bearings is imbued with MinebeaMitsumi's passion for ultra precision.

Rear wheel bearings today are usually no different than fronts in terms of a complete hub bearing or pressed-on units. In the vast majority of cases here, a complete unit is used and unbolted / bolted to the rear transaxle (2WD vehicles) or independent rear axle.

Wheel bearings live a tough life. Most of a vehicle's weight rides on the wheel bearings at the 4 corners of your vehicle. Once these bearings begin to deteriorate, a humming noise becomes noticeable. It's easiest to hear at speed when you turn the wheel slightly from side to side. When a rear wheel bearing goes out, the humming or grinding noise is usually constant. Back in the old days, wheel bearings were composed of 2 cone bearings on each front side. When removing the brake rotors (or drums) these more old-fashioned bearings could be serviced by packing the bearings with grease. While some vehicles still retain this style of bearing, it is rare. Today, aside from rear-wheel drive vehicles that use a solid axle (like trucks), most vehicles use a hub bearing. These consist of a bearing and flange surface that is bolted directly to the steering knuckle or rear transaxle. The bearing then has a hub face, with the wheel studs and tire-mounting surface. Often, an axle (often one with a CV joint) also passes through this bearing via a splined surface and has a large hub nut (called a spindle nut) that secures it at the bearing. This design makes up most bearings on vehicles today. There are some vehicles that still use a pressed-in hub bearing, where you re-use the original wheel hub, but this is becoming rare.

The classic symptom of a bad wheel bearing is typically a cyclic chirping, squealing or growling noise that changes in proportion to vehicle speed.

MinebeaMitsumi started its life as Japan's first specialised manufacturer of miniature ball bearings in 1951, and bearings have remained a primary focus of its business ever since. Our bearings are tiny components of just a few dozen millimeters in size, but they represent an aggregation of the technology and know-how that MinebeaMitsumi has cultivated for more than half a century.

All moving machines have rotating axes. Those axes are supported by bearings. Of a wide variety of bearings available, MinebeaMitsumi's greatest strength lies in miniature ball bearings with external diameters up to 22mm. Ball bearings use the low-friction rolling of balls to realize the smooth rotation of the shaft and the efficient transmission of kinetic energy to the various parts of the machine. This contributes to energy savings, longer life and reduction of breakdowns for the machinery. A precision of the bearings is linked directly to a precision of the machinery.

Next, if movement is present, inspect the lower ball joint (and upper if applicable) and see if the movement is coming from a worn ball joint. If ball joints are tight, then the wheel bearing is suspect.

How are bearings made

Without getting under the car, grab each wheel at the top and bottom with both hands. You bottom hand should reach under the tire to the backside. Your top hand should grab the front top portion of the tire. Now, try to rock the tire back and forth by pulling outward with the bottom hand, and inward with the top hand, then reversing the motion.

You can lower your wheel bearing replacement cost by changing them yourself. You should be able to do this in your own garage. However, it will require some specialized tools. Make sure to reference your vehicle’s service manual or seek out online information and determine the kind of wheel bearing your car or truck is geared up with prior to starting the repair work. Keep in mind that AutoZone rents all the specialized tools you will need to replace your wheel bearing and does so for free! Learn more about Loan-A-Tool here.

Traditional cone or roller bearings in older 2WD vehicles are often serviced when removing the rotors during a brake job. These bearings can easily be replaced, are less expensive to buy, and generally cost around $6-20.00 per unit, and $80-100.00 to service, along with the cost of replacing the rotor usually, as the bearing race is pressed in. All in, labor and rotor, most vehicles will run around $150.00 to replace and go up depending on rotor cost. In many cases, it’s cheaper to replace the rotor than it is to remove and press in a new bearing race.

Ball bearings consist of four components – an outer and inner ring, a retainer, and the balls. The outer and inner rings support the rotational motion, the balls reduce the friction from that rotational motion, and the retainer keeps the balls in place. Lubricant is also added to make the movement even smoother, and some form of shielding is applied to prevent the lubricant from leaking.

The smooth rolling motion of bearings is highly dependent on the precision of the balls. Balls that may look smooth at first glance can be found to have rough surfaces when examined with a microscope. To minimize frictional resistance to the greatest extent possible, MinebeaMitsumi bearings are fitted only with ultra high-precision balls that have been polished to the nano-level Ra (surface roughness).

World's smallest steel ball bearing capable of being mass produced was born of MinebeaMitsumi's passion for ultra precision. Although it is tiny, its precision and performance are comparable with other bearings. These bearings are being installed in Japan's finest mechanical watches, and we expect their applications to expand into a variety of fields and products in the future.

Today, aside from rear-wheel drive vehicles that use a solid axle (like trucks), most vehicles use a hub bearing. These consist of a bearing and flange surface that is bolted directly to the steering knuckle or rear transaxle. The bearing then has a hub face, with the wheel studs and tire-mounting surface.

These vehicles up until very recently still used hub systems that house roller bearings or cone style. While these bearings themselves are often as cheap as 2WD vehicles, the process of removing them and disassembling the hub is often a little more time-intensive. Expect to pay for 1-1.5 hours of labor per side, which is usually $80-160.00, plus the bearings to replace. Keep in mind if the race is damaged in the hub, it will need to be pressed out, and a new race pressed in, leading to more time.

Bearing manufacturing Machine

This production system, which was established as a result of MinebeaMitsumi's efforts in the manufacture of ball bearings, has contributed greatly to the company's expansion overseas. MinebeaMitsumi has installed the same equipment used at its parent plant in Karuizawa in its other production centers. This means that, when local employees of MinebeaMitsumi's overseas plants return home from training at the Karuizawa parent plant, they can quickly and smoothly engage in their work, and any improvements that are made at the Karuizawa plant can be immediately extended to the overseas plants. It also means that MinebeaMitsumi's overseas plants do not just support the company's production in Japan; however, they have been able to establish themselves as major, stand-alone production centers that help to underpin MinebeaMitsumi's mass production system. MinebeaMitsumi has also extended the systems that it has cultivated in the course of the development and manufacture of ball bearings to the company's other businesses, where they have made major contributions to the development and manufacture of products other than ball bearings. That know-how has become a major driving force in MinebeaMitsumi's current globalization and business diversification efforts. MinebeaMitsumi's single-minded dedication to the ultra-precision has given the company its major strengths of ultra-precision machining technologies and mass production capabilities, while at the same time, the dedication to ultra-precision continues to underpin the global manufacturing industry.

With MinebeaMitsumi's vertically integrated production system, all processes, from design and development through to assembly and testing, are conducted in-house.

Once again, these are all just approximations. However, they are a great indication of what you can anticipate paying. Fortunately, wheel bearings last a long time, so you won’t need to change them very frequently.

As of March 2016, MinebeaMitsumi has an external sales target of an astounding 180 million ball bearings a month. Taking an example of our 22-mm diameter product, if that many ball bearings were stacked one on top of the other, it would produce a column of around 3,960 km in height. That is high enough to extend beyond the earth and reach out into the space. This ability to produce ball bearings and supply them to the global manufacturing industry in such astonishing quantities is one of MinebeaMitsumi's major strengths.

The vast majority of vehicles today use a complete-unit hub bearing. Here, the cost of the bearing is usually the bulk of the expense, as most hub bearings run between $80.00 to $300.00. Many of these have ABS sensors built into them. These bearings are unbolted from the steering knuckle, and a new bearing bolted on. Expect to pay for 1-2 hours of labor to replace per side, usually between $80-200.00.

Be sure to consult your owner’s manual, a repair guide, an AutoZoner at a store near you, or a licensed, professional mechanic for vehicle-specific repair information. Refer to the service manual for specific diagnostic, repair and tool information for your particular vehicle. Always chock your wheels prior to lifting a vehicle. Always disconnect the negative battery cable before servicing an electrical application on the vehicle to protect its electrical circuits in the event that a wire is accidentally pierced or grounded. Use caution when working with automotive batteries. Sulfuric acid is caustic and can burn clothing and skin or cause blindness. Always wear gloves and safety glasses and other personal protection equipment, and work in a well-ventilated area. Should electrolyte get on your body or clothing, neutralize it immediately with a solution of baking soda and water. Do not wear ties or loose clothing when working on your vehicle.

"You can't go wrong with MinebeaMitsumi products." Although we possess world-class technology and know-how in the machining of miniature & small sized ball bearings, our pursuit of precision is not the only thing that makes this kind of favorable reputation possible. For example, if a defect occurs in any of our products, we are able to analyze it at the metallic structure and composition level and deal with the problem promptly. This is one of our company's strengths, which we have been able to achieve precisely because we manufacture all our own components in-house and because we have such an uncompromising attitude towards even the raw materials with which they are made. We offer product proposals that are not only precise, but that are suitable for our customers' applications. Our success in securing such a strong position in the industry is due to our ability to offer a steady supply of those products and to respond to any after-sales concerns with a sense of responsibility. One element that has given MinebeaMitsumi that strength is communication. In all processes, from design through to machining, assembly, and testing, communication among various departments is essential. We also travel to our overseas plants often, so we feel very close to the local employees over there as well. In some ways, Thailand feels less far away to me than traveling within Japan. It is precisely because close communication is maintained that, in each process, we can design and develop our products efficiently without waste, and offer a steady supply of quality products. Miniature & small sized ball bearings represent the company's foundations and they are the source of MinebeaMitsumi as it is today. We will continue to support those foundations and to be a presence in the company that embodies the strengths of MinebeaMitsumi.

A humming or rumbling noise while driving is usually the prime indication of a worn wheel bearing. This sound will get louder if you take the wheel and lightly turn one direction of the other at speed or go on a slight curve in the road at speed. Driving on a damaged wheel bearing can be dangerous, considering that the wheel bearing is not sufficiently lubed and friction is extremely high at this point. This friction generates heat, which will eventually disintegrate the bearing more, when can lead to complete failure, wheel off, or loss of control of the vehicle.  This can occur anytime you are driving.

Along with its ultra-precision machining technologies, another of MinebeaMitsumi's strengths lies in its mass-production capabilities. Even if a company is able to make the most high-precision products, unless it can provide a steady supply of those products to the market, it will be unable to support the manufacturing industry. In particular, with numerous ball bearings often used in a single piece of machinery, the ability to mass-produce this "staple of the industries" is essential. Ultra-precision machining and mass production technologies have been cultivated by the development and manufacture of ball bearings.

Popular in German and Japanese vehicles, these units are the sealed roller bearing that you see on the back of the complete unit. In these cases, the entire steering knuckle must often be removed from the vehicle, and the bearing pressed out, and the new one pressed in. While the cost of the bearing drastically diminishes (usually these run between $25.00-50.00) the labor involved to replace the bearing goes up, usually to the tune of 2-4 hours to replace ($160-400.00).

For MinebeaMitsumi to create systems for ultra-precision machining and mass production of ball bearings, it was vital to ensure that it would made improvements at the component and production equipment levels. While it is common for manufacturers to purchase various components from external suppliers, MinebeaMitsumi, in its quest for precision of its product parts, moved to in-house manufacture of all its components. It also made its own modifications and innovations to purchased production equipment and jigs to achieve efficient mass production. This process of trial and error fostered a culture of in-house manufacture in MinebeaMitsumi, as well as its vertically integrated manufacturing system, which controls all processes from development through to manufacture and testing.

Spin the wheel/tire by hand and listen carefully. You should hear a soft rubbing sound which is just the brake pads gliding over the rotor. A grinding sound centered in the very middle of the wheel is a dead giveaway for a failing wheel bearing. It’s important to note that when wheel bearings first start to go, it will normally be difficult to hear and tell. Usually only a road test under the weight of the vehicle will reveal that the bearing is going out.

In the case of most vans and trucks today, along with older RWD cars, the rear wheel bearings are housed inside the solid axle, and are usually pressed into the axle tube, or pressed onto the drive axle itself. In either case, the cost of the bearing is usually between $25.00-50.00, whereas the labor to remove and press in a new bearing runs between 1-4 hours.
