Installation Notes and Tips

Confirm the seal dimensions, radial shaft seal design AW/B, and dust-lip configuration before installation. Clean the sealing bore and shaft surface thoroughly, and inspect the mating surface for wear, scoring, or corrosion that could affect sealing performance. For Mercedes-Benz 300E, 300TE, S320, and related applications, verify the exact axle location against the vehicle’s service information before ordering.
