R&P Knowledge Hub
Trailer axle grease seals are dimension-specific. The inner diameter must match the spindle seal journal, and the outer diameter must match the hub bore. Even small measurement differences can cause leakage or improper fit.
The 10-225 seal is commonly used on post-1998 5.2K–8K axles, but axle configuration should always be confirmed by measurement before ordering.
