Product Details
Trailer Axle Grease Seal – 1.68" ID × 2.33" OD – UFP / Ranger Boat Trailer
Part Numbers: 168233 • 32372 • AD2527E
This trailer axle grease seal is commonly used on UFP and Ranger boat trailer axles rated up to approximately 4,200 lb capacity. The double-lip seal design helps retain grease and prevent contamination from water and debris.
This seal is often found on Trailer Buddy hubs and UFP straight spindle axles using the #84 spindle configuration (S-1377X2).
R&P Knowledge Hub
Trailer grease seals are installed in the hub behind the inner bearing to retain lubrication and protect bearings from dirt and water intrusion. Boat trailers in particular rely on proper sealing to prevent water contamination when launching.
Always verify both the inner diameter (spindle size) and outer diameter (hub bore size) when replacing seals. Many 3,500 lb and 4,200 lb axles may appear similar but use different seal sizes depending on spindle design.
