Hearing a humming or grinding noise from your rear wheel? It might be time for a new wheel bearing hub. This ECCPP set includes TWO complete rear hub assemblies, complete with the ABS sensor already built in (part number matches OE 512269). They're 5-lug hubs designed for specific vehicles. Please double-check fitment! It's listed for models like the 2000-2003 Mazda Protege (with 4-wheel ABS and rear disc brakes), 2000-2006 Mazda MPV, 2001-2002 Mazda Millenia, and some Dodge and Mitsubishi models (see full list). Replacing a worn hub restores quiet, smooth driving and ensures your ABS system works correctly for safer braking.
