Front Wheel Bearings

By having smooth metal balls or rollers, bearings minimise friction, and a smooth inside and outside metal surface for the balls to roll on. Such balls or rollers carry the load, which helps the tool to spin smoothly. Such bearings use elements like balls or rollers to avoid contact with slides. The usual practise is to provide two more or less cylindrical housings or races, the inside of which fits into and rotates with the shaft while the outer race fits into the fixed or non-rotating portion. The balls or rollers of the rolling member run freely between the two species. The rolling components of ball bearings in general are spheres of high-quality, hardened and polished alloy steel, rolling inside and out in hardened alloy steel. Such bearings are mounted in the car's knuckle assembly which is on a car's front side. Instead, a drive shaft is threaded through the wheel bearing, after the brake disc is mounted and the calliper tightens the drive shaft's key bolt and the wheel is fitted. If the front wheel bearing is poor it will make noise as the gas pedal is pressed when driving this noise is high. Lubrication is important to a ball bearing's long life. This takes heat away from bearings which are heavily loaded and avoids corrosion. Fat and oil are ideal for ball bearing lubricants. The wheel seal is supposed to fit very securely in the wheel assembly and protects the wheel bearings against dirt, water and other debris which can cause damage. There is an enormous amount of grease inside the wheel bearing which keeps the bearings running smoothly, coolly and secure. Nevertheless, the grease can and often does escape from the wheel bearing when the seal of the wheel is loose. This could weaken the bearing of the wheel, and might even stop the vehicle.
