Question:

Hello, I have a 2001 boat trailer manufactured by J.Q. TEX. Serial Number 63569 002 Axle capacity 2,500lbs GVWR and GAWR 1,900lbs The hubs are 5 bolt and are stamped UFP H-1377 I have a blown rear seal on one hub and would like to just replace both sides with new hubs that have pre packed bearings and all. These have the EZ Lube system with the rubber cap and zerk fitting out the front. Can you tell me what I need based on this info or do I need to get to the bearings and spindle? If this is a 2,500lb axle, it appears all your hubs in that class are the same specs.

We can get you what you need unfortunately you will need to take some of the measurements to make sure you get the correct bearings and seals for your trailer.

Trailer manufacturers use many different sizes when they build their systems and without precise measurements, we could not be 100 percent sure. Digital calipers are available at most tool supply stores. I have attached a drawing that shows where you can take the measurements.

We would need to know the inner diameters of the inner and outer bearing and the grease seal. These measurements will need to be as precise as possible.
