Specifications of  Hub Wheel Bearing DAC38740036/33

A wheel bearing is exactly what it sounds like: a bearing for a wheel. What's a bearing? It's a set of steel balls, held together by a metal ring called a race. There are many different styles of bearings but they are all very similar and all do the same job: they help something spin with very little friction. Like a wheel, a turbine, or a carnival ride.

Wheel bearings are used on all kinds of vehicles from bicycles to aircraft, and they all perform the same job: they allow the wheel to spin freely. Most wheel bearings are hardened steel and will withstand a lot of abuse. A wheel bearing's worst two enemies are heat and water. Heat caused by lack of lubrication can destroy a wheel bearing. Water that penetrates a sealed bearing will also destroy it.

Most wheel bearings manufactured today are sealed bearings. They come from the factory pressed together as an assembly: front race, bearing set, center race, bearing set, and outer race, with seals on both the front and rear race. Seals protect bearings from the elements, water, and debris, and they also also seal in the high-temperature grease the bearing needs. When the seal is broken or damaged, the wheel bearing will fail and start making noise.

When the seal on the wheel bearing is broken or damaged, the noise starts out very faint and becomes louder over time. Within a month, it will be very noticeable, increasing at higher speeds.

The noise is something like the noise that your tires make when hitting a rumble strip on the highway, just not quite as loud: a rhythmic rotating noise. It's something like the sound of playing cards flapping against your your bicycle spokes, remember that noise? In the video below I compare it to the whirring of a helicopter.

The only fix for a damaged wheel bearing is to replace it. If a bearing is noisy, repacking it with grease will not make the noise go away.
