Detailed Product Description

The Dorman 951-023 wheel bearing and hub assembly is designed to meet the exacting standards required for driveline and axle components. Its 26 spline count ensures a secure connection to the axle shaft, while the included flange with a triangular shape and three bolt holes provides a stable mounting surface. The assembly features four 12 mm wheel studs, which are included for convenience, and precise pilot diameters for the wheel (57 mm), brake (58.3 mm), and hub (73.45 mm) to maintain proper alignment and fitment.

This assembly is compatible with a range of General Motors vehicles, including Buick Achieva, Cadillac Cimarron, Chevrolet Cavalier, Corsica, and Oldsmobile Cutlass Calais, among others. The flange offset of 44.3 mm and bolt circle diameter of 125 mm ensure the hub fits correctly within the wheel assembly. While the assembly includes a tone ring for the anti-lock braking system, it does not come with an ABS sensor or flange bolts.

Common Applications and Problem Resolution

• Replacement for worn or damaged wheel bearings causing noise or vibration

Installation Notes and Tips

Ensure the vehicle is securely lifted and supported before beginning installation. Verify that the wheel pilot, brake pilot, and hub pilot diameters match the vehicle specifications.
