Detailed Product Description

The BCA WE61544 wheel bearing and hub assembly is a critical driveline component designed for driven axle configurations on vehicles such as the Buick Enclave, Chevrolet Traverse, GMC Acadia, and Saturn Outlook. Its 33-spline interface ensures a precise connection to the axle shaft, while the 6 M14x1.5 wheel studs provide a secure mounting surface for wheels. The modified triangle flange shape with 3 bolt holes and a 132 mm bolt circle diameter offers a stable and accurate fit to the vehicle’s knuckle, which features a 121 mm bolt circle diameter and M12x1.75 bolt hole size. The dual measurements for wheel and brake pilot diameters guarantee proper centering of both the wheel and brake rotor, reducing vibration and uneven wear. This assembly does not include an ABS sensor, making it suitable for non-ABS equipped models within the specified fitment range.

Compatible Vehicles and Applications

• Buick Enclave (driven axle models)
• Chevrolet Traverse (driven axle models)
• GMC Acadia and Acadia Limited (driven axle models)
• Saturn Outlook (driven axle models)

This wheel bearing and hub assembly addresses common driveline issues such as wheel bearing noise, vibration, and wheel hub looseness, helping restore vehicle handling and safety.

• Eliminates wheel bearing noise and roughness
• Resolves wheel hub looseness and play
• Corrects uneven brake rotor wear due to misalignment
• Improves wheel centering and reduces vibration
• Restores proper flange offset for driveline geometry

Installation Notes and Tips

Ensure the vehicle is securely lifted and supported before beginning installation. Verify the spline count and bolt pattern match the vehicle’s axle and knuckle. Clean mounting surfaces thoroughly to prevent contamination. Torque all bolts to manufacturer specifications to maintain proper flange offset and secure fitment. Since this assembly does not include an ABS sensor, confirm compatibility with the vehicle’s braking system prior to installation.
