Technical Details and Specifications

The Moog 513178 wheel bearing and hub assembly features a 27-spline axle interface, ensuring a secure connection to the drivetrain. The assembly includes five wheel studs arranged on a 114.3 mm bolt circle diameter, providing a stable mounting surface for the wheel. The triangular flange shape with three bolt holes supports proper installation and load distribution. The wheel pilot diameter measures 71.4 mm, while the brake pilot diameter is slightly larger at 71.9 mm, allowing for precise fitment of brake components. The hub pilot diameter of 100.1 mm ensures accurate centering of the hub on the axle shaft. With a flange diameter of 153.5 mm and an offset of 53.8 mm, this assembly maintains correct positioning relative to the vehicle’s suspension and braking system. Note that this part does not include an anti-lock brake sensor, so it is intended for use in vehicles without ABS sensor integration at the hub.

Applications and Problem Resolution

This wheel bearing and hub assembly is specifically designed for Jeep Liberty models, providing a direct replacement for worn or damaged components. It addresses several common issues:

• Eliminates wheel bearing noise and roughness
• Resolves wheel wobble or play caused by worn hubs
• Restores proper wheel alignment and balance
• Prevents premature tire wear due to hub misalignment
• Ensures secure wheel mounting with correct stud count and bolt pattern

Installation Notes and Tips

When installing the Moog 513178 wheel bearing and hub assembly, ensure the vehicle is securely lifted and supported. Clean the mounting surface thoroughly to remove rust and debris. Verify the spline count and pilot diameters match the axle and brake components. Torque the flange bolts to manufacturer specifications to avoid premature wear or failure. Since this assembly does not include an anti-lock brake sensor, confirm compatibility with your vehicle’s ABS system before installation.
