Installation Notes and Tips

Confirm shaft diameter, housing bore, and width before installation. Clean the sealing surface thoroughly and inspect the shaft or mating surface for scoring, corrosion, or burrs that could affect sealing performance. Use the vehicle’s service procedure for proper seating and alignment, especially on applications such as Mitsubishi Eclipse, Hyundai Sonata, and Kia Optima.
