If you're hearing a humming noise, feeling vibration in the steering wheel, or your ABS light is on, it might be time for a new wheel bearing hub. This ECCPP assembly is a direct replacement for OEM part #513121 (also fits other numbers like 713121, WB13187, etc.). It's a 5-lug front hub with ABS, made from high-quality materials for durability and reduced noise. The flange diameter is 5.80 inches, bolt size is M10x1.25, and flange offset is 2.007 inches. It fits a ton of GM vehicles from the late '90s to early 2010s—like Chevrolet Impala, Buick Century, Cadillac DeVille, Pontiac Grand Prix, Oldsmobile Aurora, and many more (check the full list in the description to be sure). The hub supports your vehicle's weight, allows smooth wheel rotation, and keeps everything securely attached. Installation involves removing the wheel, caliper, brake pads, and axle nut, then swapping in the new bearing. Always double-check compatibility with your specific year, make, and model before ordering. Keep your ride safe and smooth with a reliable hub assembly.
