Trailer hub assembly includes lug nuts, inner bearing (L44643) and race, outer bearing (L44643) and race, grease cap and grease seal. Fits 2,000-lb axles.
Dexter 8-259 should be stamped on back of hub
Note: Some axles rated at 2,000 lbs require a different seal and bearings. Be sure that the bearings in the hub being replaced have L44643 stamped on them. If the bearings have L44649 stamped on them, use #8-259-5UC1 trailer hub.
Note: Trailer wheels that are smaller than 15" and have 5 bolts, have a 5 on 4-1/2" bolt pattern.
Determining the Bolt Pattern
The first number in the bolt pattern is the number of bolt holes. The second number denotes the diameter, in inches, of the circle on which the bolt holes sit.
On wheels with an even number of bolt holes, measure from the center of one bolt hole to the center of the hole directly across from it. (Example: 8 on 6-1/2 means 8 bolt holes with 6-1/2" from the center of one hole to the center of another on the opposite side.)
To determine the bolt-circle diameter on wheels with an odd number of bolt holes, measure from the center of any bolt hole to the point halfway between the two bolt holes directly across from the first. (Example: 5 on 4-1/2 means 5 bolt holes with 4-1/2" measured to a point halfway between the opposite bolt holes.)
Measuring the distance (D) from the center of one bolt hole on the wheel to the center of a bolt hole right next to it can also help to determine the bolt pattern.

Today were going to review part number 34822545BX this is the Dexter Trailer Hub Assembly for 8-inch to 10-inch wheels with a 5 on 4-1/2-inch bolt pattern. This trailer hub assembly will include five of the 1/2-inch cone seat lug nuts. It will include both the inner and outer bearing with the same part number of L44643. It will include the grease cap and the grease seal. This hub assembly will fit 2000-lb axles. It does have a bolt pattern of 5 on 4-1/2.
The capacity on this hub assembly is 1250 lbs so when paired with another one of the same on the other side of the axle would give you a maximum of 2500 lbs. Now this hub assembly does have a diameter hub flange, in other words if I drew a circle around this whole hub assembly and measured the diameter of it, its going to be about 5-1/2 inches and that means then you can use it for 8-inch to 10-inch wheel assemblies. Now some axles that are rated at 2000 lbs will require a different seal and bearing. What you want to do is be sure that the bearings in your hub being replaced with this one will have the L44643 stamped on them because if the bearings are different like part number L44649 on them you would need to use a different trailer hub which would be the part number 8-259-5UC1. Now another thing to look at is on this hub assembly and on the one you have.
If you look, its pretty hard to see, but right in there it will be stamped 8-259. Thats stamped on the back of the hub assembly. That will mean that this one uses the L44643 inner and outer bearings. Now I also need to mention the bearing races are also included and they are preinstalled in the hub assembly. Heres the outer bearing race and as you can see, heres the inner bearing race.
Most all our hub assemblies will come with the bearing races already preinstalled on them. Last things I want to mention, this is a 5 on 4-1/2 inch bolt pattern, so basically when you have a wheel that has an odd number of lug holes like in this case five, the way to measure the bolt pattern will be just to measure from the center of one wheel stud to the stud right next to it, either way. So if you measure and it reads 2-5/8 inches that will determine this is a 5 on 4-1/2 inch bolt pattern. If you go to this product page for this part number at the bottom of the product page, therell be a table that will list when you measure the wheel stud to wheel stud across from each other measurement, it will tell you what the bolt pattern is. In this case it will be the 5 on 4-1/2 inch.
That should do it for our review on part number 34822545BX.
