Moog Wheel Bearing and Hub Assembly
A worn hub bearing changes the way a vehicle sounds, steers, and tracks, so choosing the right Moog wheel bearing and hub assembly matters before you spend time under the vehicle. The decision usually comes down to application fit, whether the replacement is a one-piece unit, and how the part is installed. Because front and rear positions can use different designs, the same name may cover several assemblies. Understanding that difference helps you avoid buying a part that looks right but does not match the knuckle or axle.
The direct answer
A Moog wheel bearing and hub assembly is generally chosen as a service replacement when the original bearing is noisy, loose, or generating an ABS fault linked to the tone ring. The direct answer is to confirm the application using the vehicle year, driven axle, and position, because a front unit often differs from a rear unit in flange shape, sensor provisions, and mounting pattern. If the vehicle uses a bolt-on cartridge design, the assembly replaces the bearing, hub flange, and sometimes the wheel speed sensor ring as one preassembled part.
Part numbers such as 515036, 515096, 513179, and 515081 illustrate why position-specific confirmation is important. A front wheel bearing hub assembly may include a different ABS lead length or sensor indexing than a rear piece, while the mounting fasteners and hub bore must match the original. When viewing a listing, treat the number as a starting point, not proof of fit. A quick cross-check against the existing hub or the vehicle application data is the most practical way to avoid installing a unit with the right brand but wrong fitment.
