Good To Know
Q: What causes a seal like this to fail? A: Typical causes are hardened rubber due to age, misalignment of the shaft, or contamination from metal debris. Replacing the seal and checking the shaft surface for scoring ensures a long-lasting fix.
Q: Should I replace both seals at the same time? A: If you are already disassembled to this level, it is common practice to replace all accessible oil seals to avoid future downtime. This seal is identical in function to the original on both sides of the axle or transmission.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
