• Uneven wheel-end rotation caused by bearing wear
• Front-end looseness or roughness at the hub

Installation Notes and Tips

Confirm vehicle fitment by year, model, position, and the Non Mexico Built Vehicle note before ordering. Verify spline count, bolt circle diameter, flange dimensions, and pilot diameters against the original part to ensure correct installation on your Mazda CX-3 or Mazda 3. Inspect related suspension and brake components during replacement so the new hub assembly is installed on a clean, properly prepared mounting surface.
