AURLTD105 Diagnose and repair light vehicle suspension systems Fill in the Missing Words 64. Place the missing words to complete the following statement about wheel bearings using the following words. Missing Words: axle, bad, commonly, front, housing, hub, maintenance, shaft, Tapered, wheel The purpose of all bearings is to allow a shaft to rotate smoothly in a Housing or to allow the housing to rotate smoothly around a shaft. Wheel and Axle bearings do this for a vehicle’s wheels. Typically, on driving axles, the Hub is mounted to the hub of an axle shaft and the Axle rotates within a housing on an axle bearing. Wheel bearings are used on non-driving axles. The wheel’s Hub rotates on a shaft called the spindle. Axle bearings are typically serviced with the drive axle. Tapered roller wheel bearings, however, require periodic Maintenance and are often serviced with suspension and brake work. Although there is a distinction between axle and wheel bearings, the bearings for the Front wheels on a FWD and 4WD vehicle are Commonly called wheel bearings. Regardless of what they are called, Bad bearings can cause noise, vibration, handling, and tire wear problems. True or False question 65. A weak suspension spring can affect the wheel alignment.
