Design and Construction
The MOOG 515151 is built to meet or exceed OEM standards, with a design focused on performance and durability. Its solid steel construction ensures excellent strength, while the protective coating helps safeguard against corrosion and rust, especially in regions with extreme weather or salted roads.
One of the standout features is its pre-assembled nature. The unit includes both the wheel bearing and hub, making installation straightforward for both professionals and experienced DIYers. The bolt-on design eliminates the need for pressing the bearing separately, which can save both time and labor costs.
The hub’s flange is precisely machined, allowing it to mate seamlessly with the vehicle’s wheel and rotor. The ABS sensor is already integrated, which makes it compatible with vehicles that require ABS monitoring without requiring additional parts.
Performance and Functionality
When installed correctly, the MOOG 515151 delivers excellent performance in terms of stability, handling, and ride comfort. It significantly reduces wheel vibration and noise, providing a smoother and quieter driving experience.
The robust bearing construction is designed to handle high radial and axial loads, making it suitable for heavier vehicles or those that are frequently used in demanding conditions—such as towing or off-road driving. The precision engineering also ensures proper alignment, reducing tire wear and improving fuel efficiency over time.
Additionally, the integrated ABS sensor allows the vehicle’s computer to continue monitoring wheel speed for optimal brake control, which is crucial for safety during emergency braking or on slick roads.
Installation Process
The MOOG 515151 is designed with a bolt-on configuration, which simplifies the installation process. For those with mechanical experience, installation can take as little as 1–2 hours using common tools such as:
- A socket and ratchet set
- Torque wrench
- Jack and jack stands
- Breaker bar
- Anti-seize lubricant
Since the hub assembly comes preassembled, there’s no need to press in the bearing, which is often the trickiest part of replacing this kind of component. Most users find that installation requires minimal hassle, provided the vehicle’s old bearing is removed properly.
It’s recommended to follow the vehicle manufacturer’s torque specifications for safety and optimal performance.
