Detailed Description

InMotion WA513011K is manufactured for precise hub replacement where correct bearing support, wheel mounting geometry, and pilot dimensions matter. The assembly is built to match OE measurements so it installs in the designated applications without altering the original suspension or hub interface. This makes it a practical choice for front hub service on Buick Century, Chevrolet Celebrity, Oldsmobile Cutlass Ciera, Pontiac 6000, and similar platforms, as well as rear service on Pontiac Fiero.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Wheel bearing noise from a worn hub assembly
• Excessive wheel play or looseness at the hub
• Uneven wheel mounting caused by damaged pilot surfaces
• Vibration related to hub wear or incorrect hub geometry
• Service replacement needs on front or rear hub applications

Installation Notes and Tips

Verify the vehicle position before ordering, since WA513011K is listed for both front and rear applications depending on model. Confirm spline count, bolt circle diameter, flange offset, and pilot diameters against the original part before installation. Because the ABS sensor is not included, reuse or source the sensor separately when the vehicle application requires one.

For best results, inspect related components such as bearings, seals, knuckles, and axle interfaces during service. Proper torque procedures and clean mounting surfaces help maintain hub alignment and bearing life.

Quality Assurance

InMotion manufactures this hub assembly using strict quality-control criteria and OE-based measurements to support consistent fitment and long-term service in the specified applications. WA513011K is built as a direct replacement part for the listed vehicles.
