A. The high temperatures produced by modern equipment have required increasing the heat resistance of ordinary soap-thickened greases. As a result, “complex” soap greases were developed. The dropping point of a complex grease is at least 38 °C higher than its normal soap-thickened counterpart, and its maximum usable temperature is around 177 °C. Complex soap greases are limited to this temperature because mineral oil can flash, evaporate or burn above this temperature. In general, complex greases have good all-round properties and can be used in multi-purpose applications. Complex greases for extreme operating conditions are often produced with solid lubricants and more highly refined or synthetic oils are used.

No, you should never drive with faulty wheel bearings. We would always recommend replacing a wheel bearing that is showing signs of wear as soon as possible because a worn bearing could fail at any time.

Besides normal wear and tear, hitting curbs with your tyres or driving over potholes can all be held responsible for damaging the wheel bearings. When it's time to get your wheel bearings changed you will notice a number of warning signs, such as:

Fluid Lubricants Fluid lubricants used to formulate grease are normally petroleum or synthetic oils. In general, petroleum oils; Naphthenic oils tend to mix better chemically with soaps and additives and form stronger structures than paraffinic oils. Synthetic oils have a higher initial cost but are effective in high temperature and extremely low temperature conditions. With increasing environmental concerns, vegetable oils and some synthetic oils are also used in applications requiring non-toxic or biodegradable grease. The base oil chosen to formulate the grease must have the same properties as when lubricating the equipment with oil. For example, lower viscosity base oils are used for grease applications at lower temperatures or high speeds and light loads, while higher viscosity base oils are used for higher temperatures or low speed and heavy load applications. Soap Thickeners

It is uncommon for the wheel bearings to fail straight away after noticing the first few symptoms related to wheel bearing failure. However, it’s better to avoid driving with worn wheel bearings because we have covered it’s a vital part of kit for your car, and can result in dire consequences for your drive-axle and steering assembly.

If something is wrong with the wheel bearing, then you cannot get the wheel bearing repaired or refurbished. The whole assembly will need to be replaced by a mechanic.

The soap thickener dispersed in the base liquid gives the grease its physical character. Soap thickeners not only provide the consistency of the grease, but also affect desirable properties such as water and heat resistance and pumpability. They can affect the amount of additives, such as rust inhibitors, required to achieve the desired quality. Soap affects how grease flows, changes shape, and wears when mechanically operated and in extreme temperatures. Each type of soap adds its own characteristic properties to the grease. The soap concentration can be varied to obtain different grease thicknesses. Additionally, the viscosity of the base oil also affects the thickness. Since the qualities of soap are also determined by the fatty acid from which the soap is prepared, not all greases made from soaps containing the same metals are the same. The name of the soap thickener refers to the metal (calcium, lithium, etc.) from which the soap is prepared. Complex Soap

Over time, your wheel bearings can become worn. If you hear any unusual noises coming from your wheels, they're likely damaged. To keep your wheels moving smoothly and safely, you may need to get your wheel bearings replaced.

Car modifications, such as fitting larger or wider rims, tyres with lower thread walls, stiffer shock absorbers and suspension springs cause higher loads on the wheel bearing and hasted wear

An unusual grinding or grating noise which worsens as you accelerate – be cautious as it can sound similar to damaged tyres

If your wheel bearings are making a noise, or you feel your car vibrate at speed, then it’s time to get them changed because they can affect alignment and steering.

The function of grease is to remain in contact with and lubricate moving surfaces without leaking under gravity or centrifugal action or compressing under pressure. Its main practical requirement is that it retains its properties under shear at all temperatures to which it is exposed during use. At the same time, grease must be able to flow into the bearing and from point to point in the lubricated machine via grease guns when necessary, but must not contribute significantly to the power required to start the machine, especially during start-up.

Looking for specialists near you to change your wheel bearings? You will find the best wheel bearing fitting mechanics and garages in your area below.

A front or rear wheel bearing replacement isn’t a time intensive job for a garage, but with that said, it is still fairly complex and can take more time when parts need to be removed to gain access to your wheel bearing. Garages will have the specialist equipment and training to do the job safely, and therefore wheel bearing replacement should only be carried out by a professional mechanic.

The wheel bearing is an important part of wheel assembly, connecting the wheel to its axle. When wheel bearings wear, they make a rumbling noise that worsens until the bearing fails. That's why it's really important to get it changed when it does get damaged, as its role is to ensure the wheel is able to rotate smoothly and with minimum friction, keeping you on the road safely.

Grease is a semi-liquid to solid mixture of liquid lubricant, thickener and additives. The liquid lubricant that performs the actual lubrication can be petroleum (mineral) oil, synthetic oil or vegetable oil. The thickener gives grease its characteristic consistency and is sometimes thought of as the "three-dimensional fibrous network" or "sponge" that holds the grease in place. Common thickeners are soaps and organic or inorganic non-soap thickeners. The majority of greases on the market consist of mineral oils mixed with soap thickener. Additives improve performance and protect grease and lubricated surfaces. Grease is defined as a temperature-regulated feeding device: When the lubricant film between wear surfaces is thinned, the resulting heat softens the adjacent grease, which expands and releases the oil to restore film thickness. Function

They are used on a variety of other automobiles from cars, airplanes and bikes. In cars, the wheel bearing rides on a metal axle shaft and fits securely inside the wheel hub.

B. A "complexing agent" made from a salt of said metal is an additional ingredient in forming a complex grease. A complex soap is formed when a fatty acid and alkali react to form a soap, and the alkali simultaneously reacts with a short-chain organic or inorganic acid to form a metallic salt (complexing agent). Basically, a complex grease is obtained when a complex soap is formed in the presence of a base oil. Common organic acids are acetic or lactic, while common inorganic acids are carbonates or chlorides. Additives

B. Combining greases consisting of different base oils may produce a liquid component that does not provide a continuous lubricating film. When greases containing different additives are mixed, the additives may be diluted. Blended greases may become less resistant to heat or have lower shear stability. If a new brand of grease must be used, the component part should be disassembled and thoroughly cleaned to completely remove the old grease. If this is not practical, new grease should be injected until all traces of the previous product have been removed. Additionally, initial grease changes should be made more frequently than normally planned.

Wheel bearings have an average lifespan of approximately 85,000 to 100,000 miles. This is only guidance though, and not the case for every car. The true lifespan will depend on the quality of the wheel bearing part, and also, the driving conditions that the car goes through.

Compare wheel bearing replacement costs from garages near you. We found on average, when you book your wheel bearing replacement with FixMyCar, prices vary but an average figure is of around £257.63.

The car’s wheel bearings are a series of steel balls secured together on a metal ring called a race. Each wheel of your car has a wheel bearing, which supports the weight of your car. Its function is to let your wheels move and turn with as little friction as possible.

When your car feels loose when driving it, or, when your steering seems less responsive to turns and feels less precise than normal.

If you want the full package of wheel alignment, then this is the service for you. Wheel alignment is needed for stability and to ensure the four wheels of your car are tracking straight. If your vehicle veers to the left or right whilst driving or your tyre treads are wearing unevenly, your car may need a wheel alignment.

Wheel bearings have an average lifespan of 85,000 to 100,000 miles. This is only a rule of thumb though, the actual lifespan of a wheel bearing depends on the quality of the wheel bearing and the operating conditions

Yes, wheel bearings are a vital part of your car, and should you leave them in a bad condition, it can affect other car parts and ultimately be very dangerous too. Complete failure of the wheel bearing can result in the wheel seizing up entirely, making your car undriveable.

Grease and oil are not interchangeable. Grease is used when it is not practical or convenient to use oil. Lubricant selection for a particular application is determined by matching machine design and operating conditions with the desired lubricant properties. Grease is commonly used for:

A. Greases are considered incompatible when the physical or performance properties of the blended grease fall below the original specifications. In general, greases with different chemical composition should not be mixed. Mixing greases with different thickeners can create a mixture that is too hard to provide adequate lubrication or, more commonly, a mixture that is too soft to stay in place.

There are applications where surface-protecting and performance-enhancing additives are used that can effectively increase the overall performance of a grease. Solid lubricants such as molybdenum disulfide and graphite are added to grease in certain applications at high temperatures (above 315 °C) and extremely high pressure applications. Adding solid additives requires frequent grease changes to prevent solids buildup (and the resultant wear) in components. Dyes are also available that improve the appearance of grease and are used for identification purposes. Types of Grease
