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 we're going to take a quick look at Dexter Axle's Trailer Hub Assembly part number 84550bx. Now this hub has a capacity of 1,750 pounds. When you pair it up with another you'll get a total capacity of 3,500 pounds, which is right where we need to be for use with a 3,500 pound axle. There are 5 studs pressed into the hub and we've got a bolt pattern of 5 on 5. If you measure from the center of one stud to the center of the next stud you'll get a 3 inch difference, which tells us it's a 5 on 5 pattern. Now, included with the hub are the races, but they're actually already pressed into place inside the hub.
You also get your 5 conical lug nuts for securing the wheel to the hub, a grease cap that's going to go over here on the front to protect the lubricated internals, your inner and outer bearing. The inner bearing in this case is an L68149. The outer bearing is an L44649. And you'll also get your grease seal that will go on the back. And that's it for a quick look at Dexter Axle's Trailer Hub Assembly part number 84550bx..
