• The inner race fits onto the axle shaft, which is not directly part of the wheel bearing, but connects to the wheel hub. The axle shaft transmits power from the differential to the wheel.
• Ball bearings, shown as small, evenly spaced metal spheres, are situated between the inner and outer races. These bearings allow the wheel to rotate smoothly with minimal friction.
• A grease seal, typically made of rubber or a synthetic material, is visible on both sides of the bearing. These seals prevent contaminants, such as dirt, water, and debris, from entering the bearing and damaging the ball bearings, while also retaining the grease that lubricates the bearing.
• A bearing retainer or cage, a thin metal or plastic component, keeps the ball bearings properly spaced within the bearing assembly. This prevents the bearings from bunching together and ensures even distribution of load.
• The hub assembly also includes a wheel speed sensor (if applicable), which monitors wheel rotation speed for the vehicle’s anti-lock braking system (ABS) and other electronic systems. This sensor is typically mounted near the bearing and reads a tone ring or reluctor ring on the axle or hub.
• The illustration shows the brake rotor, which is bolted to the wheel hub. The brake caliper, which houses the brake pads, clamps onto the rotor to slow or stop the vehicle.

Proper Use of a Bearing Puller Tool

The correct use of a bearing puller is essential for safely and effectively removing a wheel bearing. This illustration focuses on the proper setup and execution of the bearing removal process.The illustration shows a bearing puller tool in use on a Can-Am Defender wheel bearing assembly. The puller is specifically designed for this task, ensuring that the force is applied directly to the bearing’s inner or outer race, avoiding damage to other components.

• The illustration showcases the wheel hub assembly, which has been removed from the vehicle. The brake rotor is still attached for clarity.
• The bearing puller consists of several key parts: a forcing screw, a bearing separator (also called a “claw”), a puller body, and adaptors. The specific components may vary depending on the puller design.
• The bearing separator is positioned behind the bearing race that is being extracted, ensuring that the force is applied directly to the race. The separator is adjusted to securely grip the bearing race.
• The puller body is connected to the bearing separator, providing a framework for the forcing screw.
• The forcing screw is threaded through the puller body and is turned with a wrench or other tool. As the screw is tightened, it pushes against the axle shaft, pulling the bearing out of the hub.
• Adaptors may be used to customize the puller to fit different bearing sizes and configurations. These adaptors are inserted between the forcing screw and the axle shaft to provide a solid point of contact.
• The illustration also depicts the importance of applying penetrating oil to the bearing and hub before using the puller. This reduces friction and makes the removal process easier.
• The illustration highlights the use of a protective sleeve to prevent damage to the axle shaft threads.

This illustration emphasizes the importance of proper tool usage to prevent damage to the wheel hub or other vehicle components.

Correct Method for Applying Grease to a Wheel Bearing

Proper lubrication is crucial for wheel bearing longevity. This illustration details the correct method for applying grease, maximizing its effectiveness.The illustration demonstrates the process of applying grease to a wheel bearing, either during initial assembly or as part of a maintenance procedure. The focus is on ensuring the grease reaches all critical bearing surfaces.

• The illustration shows a disassembled wheel bearing assembly. The wheel bearing is removed from the hub and is visible.
• A grease gun is being used to apply grease. The grease gun is loaded with the appropriate type of grease, specifically designed for wheel bearing applications.
• The illustration shows the grease being applied directly to the ball bearings and the races within the wheel bearing. The grease gun nozzle is carefully positioned to ensure the grease penetrates all areas.
• The illustration shows the bearing being packed with grease. The grease is worked into the bearing by hand, ensuring all surfaces are coated. This is especially important for new bearings.
• The illustration also highlights the importance of filling the bearing cavity with the correct amount of grease. Too much grease can cause heat buildup, while too little will not provide adequate lubrication. A general guideline is to fill the bearing cavity approximately two-thirds full.
• The illustration includes a close-up view of the grease application process, emphasizing the importance of even distribution and complete coverage.
• The illustration also shows the proper method for cleaning the wheel hub and related components before reassembly, ensuring a clean environment for the new grease.
