Installation Notes and Tips

Verify rear fitment by year, model, and position before installation. Confirm the 30-spline count, 5-stud wheel pattern, and sensor connection match the original assembly on the vehicle. Inspect the mating surfaces, axle components, and brake hardware for wear before pressing or bolting in the new hub assembly. Proper torque procedures and alignment checks should be followed during reassembly.
