Installation Notes

Verify shaft and housing dimensions before installation: 45.000 mm shaft and 62.000 mm housing bore. Inspect the sealing surface for scoring, corrosion, or wear before pressing the seal into place. Clean the bore thoroughly and install the seal squarely to avoid distortion. Confirm the vehicle position matches the listed front application for your specific year and model, including Hyundai Santa Fe, Kia Sedona, and Genesis G70/G80/G90 front fitments.
