Is a Noisy Wheel Bearing an MoT Failure?

The noise at the rear of your car may be a sign of a bad wheel bearing. The noise will increase with every kilometer you drive. As the bearing wears out, it loses its lubrication, which makes it unbearably hot when accelerating. When this happens, the wheel bearing will no longer support the load and becomes wobbly. This is why it is important to drive at a steady speed and listen for a loud noise. If you hear one of these symptoms, it is highly likely to be a bad wheel bearing.

There are several ways to find out if your wheel bearing is bad. For starters, the type of wheel bearing you have will determine how long it will last. While most wheel bearings can live up to a hundred thousand miles, you should still inspect your wheel bearing every three to five years. The lifespan of your bearing also depends on the type of road conditions and driving style you use. If you drive fast and over bumpy terrain, the bearing could wear out sooner. Also, the quality of the wheel bearing will determine how long it lasts. A high-quality wheel bearing may last 75,000 to a hundred thousand miles, depending on the type of load your car puts on it.

To avoid spending too much money, consider purchasing remanufactured wheel bearings. These are typically half the price of OEM parts. However, the cost will vary greatly from car to car. Depending on the car model, you may want to spend a few extra dollars on a remanufactured wheel bearing. The warranty is usually good too. It’s easy to get replacement parts for wheel bearings from a 3rd party manufacturer.
