The "car wheel bearings" sit between a cone screwed to the wheel axle and the cup in the wheel hub. They must be properly adjusted and greased. To find out if everything is ok without taking everything apart, simply remove the wheel from the bike and turn the axle with your fingers. Everything turns nice and smooth without any play? Good, then you probably don't have to worry about anything. If the axle is stuck, very hard to turn or is very loose, you have to regrease your bearings propbably anyways. Here's how to:

Car wheel bearings support the wheel hubs on the axles. Bearings require a certain amount of pressure, otherwise referred to as preload. The specific amount of preload determines the number of bearings that support the wheel hubs at any given time. Cone flats thread onto the axles and press bearing cones against the bearings. Adjusting ina bearing cone preload prolongs the life of the bearings. With proper preload, light drag should be noticed when spinning the wheels.Wheels with quick-release levers present a challenge. Closing the lever alters the preload. Adjusting bearings on wheels that have quick-release levers may take several attempts.

The car wheel bearings sit between a cone screwed to the wheel axle and the cup in the wheel hub. They must be properly adjusted and greased. To find out if they need greasing without taking everything apart, simply remove the wheel from the bike, support the axle horizontally with your fingers, and turn the wheel slowly--try not to tilt the axle as it rotates. If the wheel does not turn smoothly or you can feel tiny bumps in your fingers, then you must dismantle the bearing assembly and service the skf bearings.

Car wheel bearings should last for years and provide you with thousands of miles of travel---but they won't last forever. In some cases they even fail completely if they haven't been maintained correctly. Part of a maintenance schedule should include replacement of wheel bearings before they fail. The procedure isn't that difficult if you have about an hour and a few small tools. Front and back wheels are similar in procedure to change bearings and only require slightly different tooling.

Car wheel bearings cost are typically located right at the spindle of the wheel hub to allow free wheel movement. By minimizing the friction that goes with metal to metal surface contacts as your car rotates, the functionality of the part is crucial to the overall performance of your vehicle. Keeping the part periodically greased or re-packed every two years, which is equivalent to 24,000-mile service, is essential to keep it in top notch working conditions. Proper greasing could also facilitate efficient flushing mechanisms to do away with any form of contaminants which can induce wearing and corrosion. Once the part fails, find immediate replacement for your wheel will not run properly without working sets of car wheel bearings.
