Only the models, series, years, drivetrain, and six-lug configuration explicitly listed above are supported by the source.

Not confirmed: 2WD vehicles, eight-lug applications, unlisted 2500/2500HD/3500 trucks, rear-axle use, unlisted model years, or vehicles whose ABS system, connector, flange dimensions, mounting pattern, axle interface, or brake package differs.

Installation Notes

Professional installation is recommended. Confirm that the vehicle is 4WD or AWD and uses the listed six-lug front hub before disassembly. Safely support the vehicle and follow the vehicle-, drivetrain-, and brake-package-specific service procedure.

Compare the replacement hub with the original for flange diameter, hub pilot, bolt circle, stud pattern, mounting points, axle interface, ABS sensor location, connector, cable length, and routing. Clean the steering-knuckle mounting surface and remove corrosion or debris without damaging the mating face.

Inspect the axle splines, steering knuckle, CV axle, brake components, dust shield, fasteners, and ABS wiring. Replace damaged or manufacturer-designated single-use hardware as required. Use the vehicle manufacturer's tightening sequence and torque values for the hub mounting bolts, axle nut, brake components, and wheel fasteners. Incorrect axle-nut torque can damage the bearing or create wheel play.

Route the ABS lead exactly as required, secure it away from rotating, moving, or hot components, and verify the connector is fully seated. After assembly, check wheel rotation, brake operation, ABS and stability-control warning lights, wheel play, and abnormal noise. Complete an alignment check if required by the service procedure or related suspension work.
