Detailed Description

InMotion WA515018 is a front wheel hub assembly designed for heavy-duty Chevrolet and GMC 4x4 platforms, including the Chevrolet K2500, Chevrolet K3500, GMC K2500, and GMC K3500, plus K2500 Suburban applications. The assembly is manufactured with precision processes and strict quality-control standards, using OE data to match the original dimensions and mounting points required for proper front-end service. The modified-circle flange shape, 33-spline configuration, and specified pilot and bolt-circle measurements help ensure correct alignment with the vehicle’s hub and brake interface.

This part number, WA515018, is intended as a direct replacement for the original front hub assembly on the listed applications. It is a practical choice when servicing worn wheel bearings, noisy hubs, or front-end components that no longer maintain proper wheel support. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Fix

• Front wheel bearing noise or rough rotation
• Excessive wheel play at the hub
• Vibration or looseness from a worn front hub assembly
• Improper wheel support on Chevrolet K2500, Chevrolet K3500, GMC K2500, and GMC K3500 front axles
• Fitment issues caused by a damaged or incorrect replacement hub

Installation Notes and Tips

Confirm the vehicle’s front application, spline count, bolt circle, pilot diameters, and flange dimensions before installation. Because the ABS sensor is not included, reuse or source the correct sensor separately if your vehicle requires one. For best results, inspect related front-end components, clean the mounting surfaces, and torque fasteners to the vehicle manufacturer’s specifications during service.

Quality Assurance

InMotion manufactures this hub assembly using OE-based measurements and controlled production standards to support consistent fit and dependable performance on the listed Chevrolet and GMC applications.
