What Are Front Wheel Bearings?
A front wheel bearing is a set of steel balls held together in a metal ring, called a race. At the center of the wheels, there is a hollow piece of metal, called a hub. The wheel bearings fit tightly inside this hub, and ride on a metal axle shaft, helping reduce friction when the wheel spins.
Types Of Front Wheel Bearings
- Ball Bearings - Easily the most common type of wheel bearing, the ball bearing is also the most versatile. Ball bearings have the ability to absorb both radial and thrust loads. Radial load is the amount of weight put on a wheel. The thrust load is cornering pressure. Ball bearings can be found in wheels as small as those on roller skates to tires as large as those on automobiles.
- Roller Bearings - Roller bearings are also commonly used wheel bearings; however, they do not have the versatility of ball bearings. They handle the radial load well but do not hold up under thrust. This makes them virtually unusable in wheels that have to corner with even moderate amounts of speed.
- Tapered Roller Bearings - Tapered roller bearings are most often used in standard cars and trucks and wheels. The cone shape allows for the reduction of friction during cornering when thrust load is at its greatest. When a car turns, the wheels angle to varying degrees. Tapered roller bearings allow for this to keep shifting parts from grinding.
Important Features Of Front Wheel Bearings
Bearings reduce friction, they support the weight of the vehicle, they withstand the lateral forces at corners, bearings are sealed tightly to prevent dust and water contamination, wheel bearings are durable, Wheel bearings are made using high-quality steel.
How Does Front Wheel Bearings Works?
A steering knuckle is a stub axle that is used as a connection point between the tie rod and wheel. Steering knuckles also connect the lower and suspension upper ball joints. Disk-brake systems use steering knuckles as a brake-caliper mount. The front wheel bearing is fitted in the knuckle assembly of the car which is on the front side of a car. A drive flange is then pressed from outside of the bearing. A drive shaft is then inserted through the drive flange, after assembling of the brake disk and the caliper the main bolt of the drive shaft is tightened and the wheel is then fitted. When the drive shaft moves the drive flange moves due to the bearing in it, allowing the wheel to move.
Frequent Problems With Front Wheel Bearings
If the front wheel bearing is bad it will make noise, If seals get damaged it can lose its grease and dust and water contamination can damage the bearing, Over tight bearing can make noise, Snapping, clicking or popping noise, Grinding noise when the vehicle is in motion, Knocking or clunking noise, Wheel vibration and wobbling of wheel, Shudder, shimmy or vibration at a constant speed, Abnormal side pull when brakes are applied are some of the problems.

Once the car is raised, position a jack stand under the car for stability. Remove the bolts that secure the wheel and remove the wheel. Remove the front right brake caliper assembly; Remove the dust cover, cotter pin, and castle nut of the drive shaft. Remove the drive flange, remove the knuckle assembly. Inside the knuckle assembly, you would find wheel bearing, remove the wheel bearing. Take new wheel bearing and fit it in knuckle assembly and reverse the process as removed.
