Installation Notes and Tips

Verify bore, outside diameter, width, and race dimensions before installation to confirm proper fitment. Inspect the axle shaft, housing, and mating surfaces for wear or damage, and replace any components that could affect bearing alignment or seating. Clean all contact surfaces thoroughly so the bearing installs squarely and operates smoothly.
