Wheel bearings play a critical role in keeping your vehicle safe, smooth and on the road. Wheel bearings are typically located at the spindle of the wheel hub to allow free wheel movement. Wheel bearings are designed to support the weight of the vehicle and allow it to roll with minimal force while withstanding the loads from high speed cornering and hard acceleration and braking. Wheel bearings must withstand outrageous temperatures and conditions, if contaminated with mud, dirt, rain or snow they can and will deteriorate quickly. Wheel Bearings need regular service; the bearings should be greased and or cleaned and repacked every two years or every 24,000 miles for maximum longevity. Wheel bearing problems and failures can be hard to detect so have them checked regularly. Noise is a clue that something is wrong. The noise from a bad wheel bearing will change pitch as the wheel speeds up and slows down when turning from one direction to the other, and most times the noise will transfer to the opposite wheel. When the weight is increased on a bad or worn bearing the noise increases. While turning the inside tire always rotates at a lower rpm than the outside tire. When the outside wheel has the bad bearing, the noise will become worse because that wheel is turning faster. Another possible indicator of a faulty or worn wheel bearing is a decrease in bearing noise level when applying the breaks.
