Wheel bearings have an average lifespan of 136,000 to 160,000 km (approximately 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.

This question could have a multitude of answers, with none of them really providing good news. Cars tend to make a grinding noise when something is wrong. How wrong will depend on a number of circumstances, but we'll take a look at some of the major culprits below with some suggestions as to what may need to be fixed in each instance.

If the grinding sound does not happen when you are braking but when taking a fairly tight turn, this could be caused by a failing joint on a front wheel drive car. Specifically, the constant-velocity joint. This sort of grinding should not be taken lightly, as it is going to affect the way in which the car drives. If this sound is ignored for long enough, your front wheel drive car will become a one wheel drive car, which in most cases just won't go. Calling your garage and booking a service at this point is vital.

If your car makes a grinding noise under braking, it is likely that you have worn brake pads that may be in need of replacement. A squealing or whining sound is usually the first sign that brakes are on the way out, so if before the grinding started you were met with this high-pitched sound then it’s likely that is the cause. The grinding, in this case, is caused by the metal backing plate where your brake pad used to be clamping directly onto the disc. This reduces the braking ability of the car, making driving dangerous. It is imperative that you get the brakes repaired at this point, but by ignoring the squealing sound before it is likely that the entire job is going to be more expensive due to the cost of having the brake discs replaced as well as the pads.

Having said that, it is best to avoid driving with a worn wheel bearing for any length of time. As we’ve already seen, the wheel bearing is essential for connecting your wheel to your car, and any weakness in this connection could have severe consequences for your drive-axle and steering assembly – as well as for your safety.

When replacing your wheel bearings, it is essential to look for high quality parts. MOOG offers a complete range of easy to install, premium quality, long-lasting wheel end bearings that are engineered, manufactured, tested and validated to OEM standards for maximum performance and durability.

Despite the fact that modern wheel bearings are easier to install than previous generations, correct installation, the usage of appropriate tools and respecting the specified torque values are still essential for maximum performance, durability and safety. Therefore, we recommend having your wheel bearings fitted by a professional mechanic that has the skills and the tools to do the job.

Of course, unless you are confident in car servicing, it’s always advisable to call in to seek professional assistance. Our years of experience tell us that a considerable amount of work carried out by mechanics involves fixing jobs completed by enthusiastic but unskilled amateurs. Your safety is at risk if you attempt a job that you are unsure about completing.

Potentially less serious causes of grinding, which will happen on a far more intermittent basis, include having a pebble lodged between the brake pad and disc. Similarly, a failing alternator or bearings could also cause a car to make grinding noises when it is moving. The main message here is that if your car is making a grinding noise, the smart thing to do is to get it checked out as soon as possible. If you feel as though your car is not performing optimally, why not call into your local Protyre garage, or book a free vehicle safety check using the button below.

Wheel bearings are low maintenance parts, but that doesn’t mean they last forever. So, what does a wheel bearing actually do? How long does it last? And how can you help extend its lifespan?

A wheel bearing is a crucial part of the wheel assembly that connects the wheel and the axle. It is a set of steel balls (ball bearings) or tapers (tapered bearings), held together by a metal ring. It enables the wheel to rotate smoothly with a minimum of friction. Wheel bearings are safety critical components designed to sustain radial and axial loads caused by gravitation, acceleration, breaking & cornering forces, so they need to be replaced when they stop working properly.
