Trailer hub includes lug nuts, inner bearing (L68149) and race, outer bearing (L44649) and race, grease cap and grease seal. Fits 3,500-lb axles.
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 84545BX this is the Dexter Trailer Hub Assembly with the 5 on 4-1/2-inch bolt pattern. This application will fit most 3500-lb axles including Dexter. This trailer hub will include the five 1/2-inch cone seat lug nuts. It will include the inner bearing, part number L68149, the outer bearing part number L44649. It will include the grease cap and the grease seal, part number 58846. Now the bearing races are also included but they are preinstalled already into the hub.
As you can see the outer bearing race is right there and on the back youll see the inner bearing race right there. Usually all of our hub assemblies will include the bearing races already preinstalled installed into the assembly. This does have a capacity of 1750 lbs so when used with another hub assembly on the other side of the axle would give you your maximum of 3500 lbs. This does have a bolt pattern of 5 on 4-1/2-inch dimension and basically the way you can measure that is on a bolt pattern that would be an odd number lugs like in this case five, if you would just measure from the center of one wheel stud to the center of the wheel stud right next to it either way and that would be 2-5/8 inches and that would determine that this a 5 on 4-1/2-inch bolt pattern. Basically if you go to the product page for this part number at the bottom of the page will have a chart list that will show you when you measure the spacing between two side by side lug wheel studs that when its 2-5/8 that will mean its a 5 on 4-1/2 inch bolt pattern.
And that should do it for our review on part number 84545BX.

I ordered 2 complete hubs, plus Bearing Buddies, wheel and tire, winch and a fender on Monday. Monday night received an email that all had shipped, had it on my front porch on Thursday via UPS ground. Everything arrived complete and in good order. The website is worth its weight in gold for a DIY er like me as it contains a ton of info on how to measure, videos on what is included and great installation videos. Helps your confidence when you only do this kind of job once every ten years! My boat trailer is a 2002 venture V-2200.60872

This was my second order from etrailer and they are first on my list for future purchases. The products are of good quality and as described, no hype. The real test for me was the promptness of getting my questions answered after the purchase. Their web-sight provides enough information to make good product selections the first time out.27228

Everything fit perfectly except the grease cap. The bearings,rear seal and hub went together without a problem. I destroyed one cap trying to get it on and dented the other. Way too tight of a fit.9920
