Includes OE SKF wheel bearing and hub assemblies along with required replacement screws, an ideal solution for servicing both front wheel bearings

A failing wheel bearing will make a lot of tell tale sounds. A good example of this is a humming sound at highway speeds. Additionally, a bad wheel bearing will also make groaning or clunking sounds while turning. If your BMW's wheel bearings are making this noise we highly recommend immediate replacement.

Please note: Wheel bearing bolts must be replaced when installing the new wheel hub assemblies. BMW TIS torque specs for the M12 bolts are 80Nm (~59 ft lbs) + 90 °. The axle nuts must be torqued to 420Nm (310 ft lbs).

NTN is an OEM Wheel Hub Assembly manufacturer for BMW.

NTN/BCA Wheel Hub Assembly

Application-Specific Engineering Design to ensure the correct fit, function and high performance of the hub unit.

Each BCA hub assembly is engineered to the OE design and specification for its make & model. Then, each hub goes through rigorous testing to ensure that the part performs to BCA's exacting standards.

Application-Specific, OE-Style ABS Plugs & Sensors to ensure proper connection & performance. Each sensor on BCA hubs is verified with the OE specs to ensure proper functionality of the ABS module on the vehicle. Components Made with Premium Quality Materials to ensure that our customers receive a robust, durable product. These components include forged steel rings, seals, precision cages, rolling elements, grease and hub bolts.

Features and Benefits:

• Forged Steel in the inner and outer rings must meet BCA's stringent steel quality specifications, which optimizes bearing life.
• Seals are customized for each BCA hub based on application-specific materials & design requirements to minimize the chance of contamination and maximize bearing life.

Installation Note: Some bearings contain active wheel sensors. These wheel sensors normally work together with magnetic ABS sensor rings. These sensor rings have a magnetic north and south poles lying next to each other in its circumference. These magnetic poles must always lie opposite the wheel sensor. If, the wheel bearing is installed improperly, the system wheel sensor and magnetic sensor gear cannot supply a signal making the ABS system inoperable.

The ATE Test Card for Magnetic Sensor Gears will assist in prevention of these errors. PN# 760130 ATE
