Good To Know
Q: Can this oil seal work for both front and rear applications?A: Yes, as long as the shaft diameter and housing bore match the seal dimensions. Confirm your specific location and measure before ordering.
Q: What causes oil seals to fail early?A: Misalignment, a scored shaft, or installing with the lip facing the wrong direction. Always inspect the shaft surface and install with the sealing lip toward the oil side.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
