There are several mechanical problems that can also display similar symptoms including over or under inflated tires, worn out CV joints, damaged shocks or struts, and suspension out of alignment. In many cases, this leads to excessive tire wear on the inside or outside edge of the tires. If the wheel bearing is damaged, it displays a few warning signs or symptoms that alert the vehicle owner to replace the wheel bearings as opposed to simply cleaning and repacking them.ДЄbnormal tire wear: When the wheel bearing is loose or worn out, it causes the tire and wheel not to align on the hub properly. When the wheel bearing fails, it's often due to the loss of lubricity inside the wheel bearing housing.

The interior of the wheel bearing is attached to the drive shaft (on front wheel, rear wheel and four-wheel drive vehicles) or spins freely on a non-drive axle. The wheel bearings are inserted inside the wheel hub, which secures the wheel and tire to the vehicle. When a wheel bearing is properly packed with grease, it spins freely and without developing excess heat. Part 1 of 3: Determining the symptoms of a dirty or worn out wheel bearings

It's also a good idea to purchase a service manual for your vehicle to learn the precise steps for locating and replacing this component on your vehicle, as it can vary based on individual vehicles. If you notice any of these symptoms, it is recommended to replace the bearings as opposed to simply cleaning the old ones. In the sections below, we will articulate the symptoms of a worn out wheel bearing.

We will address the general instructions for cleaning and repacking wheel bearings that are not worn out. It's also very common for dirt and debris to seep into the wheel bearing housing either due to brake dust or other contaminants near the wheel hub. The reason for this is that eventually grease loses a lot of its lubricity due to age and heat. Most automotive manufacturers agree that wheel bearing repacking and cleaning should be completed every 30,000 miles or once every other year. 'Maintenance free' single wheel bearings designed to extend the life of wheel bearings without having to be serviced eventually took over.ДЄlthough many of the vehicles on the road have this new style of wheel bearing, older vehicles still need them serviced, which includes cleaning and repacking the wheel bearing with fresh grease.

If they break entirely, it causes a wheel/tire combination to fall off the car while driving, a very dangerous situation.Д«efore 1997, most vehicles sold in the United States were designed with an inner and outer bearing on each wheel usually serviced every 30,000 miles. If they are not cleaned and repacked, they wear out and need to be replaced. Wheel bearings are designed to last a long time eventually, however, they lose their lubricity due to excess heat or debris that somehow finds its way into the center of the wheel hub where they are located. Although the construction, design and materials used today are quite different than in years past, the basic concept of needing proper lubrication in order to work efficiently remains. Since the invention of the modern vehicle, wheel bearings have been used in some capacity to allow the tires and wheels to spin freely as the vehicle moves forward or in reverse.
