Shipping SpecialTrailer 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.
Features:
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 8-258-5UC1 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 we're going to take a quick look at Dexter Axle's Trailer Hub Assembly for 12 inch to 15 inch wheels, part number 8-258btuc1. Now this idler hub has a capacity of 1,250 pounds, so when you pair it up with another of the same hub on the other side you'll get a total capacity of 2,500 pounds on your hubs which puts this in the range for a 2,000 pound axle. It uses a 5 on 4 1/2 bolt pattern and we can determine this by measuring from the center of one stud to the center of the stud adjacent to it and we get a measurement of 2 5/8 inches, which indicates that it's a 5 on 4 1/2. Now included with a hub you'll find the races, which are already pressed into place inside the hub. You'll also find your grease seal. In this case it's a 34823.
Your inner and outer bearings. In this case they're both L44643. As well as the grease cap and the 5 conical lug nuts for securing your wheel to the hub. And that's it for a quick look at the Dexter Axle Trailer Hub Assembly part number 8-258btuc1.

This product arrived quickly and fit well. It is of equivalent or better quality than the original hub and bearings on my Snowbear trailer, which had rusted rather badly. I like having studs and lug nuts instead of lug bolts. I also like having it ungreased so I can know what kind of grease I am putting in and not worry about compatibility (lithium vs. calcium, etc.). My only beef is that it should come with a new cotter pin and ideally, a new castle nut to truly be complete. Thanks to etrailer for listing enough dimensions that I could pick out the correct hub, since the originals had no numbers on them.50536

I was surprised to find that the hub wasn't assembled with the bearings pre-packed. An easy fix for sure, but a surprise nonetheless. 35383

Great service and product, everything exactly as advertised. The hubs are going to go on a BBQ grill that we are changing the wheel size from 8" to 15". It is unusual to find a company that provides the service and product quality level this company does, what a pleasure dealing with them.--Thank-you.28525

20/20 hindsight tells me I made a bad decision when I got a 20% discount on a display model utility trailer from a large "big box" hardware store here in the Seattle area. Many of the parts were assembled incorrectly, some of the hardware was missing, and they'd adjusted the wheel bearings too tightly which ended up frying one of them and the associated bearing races just during the trip home. The bearing races were integral with the hubs and weren't servicable, so the hub was ruined. And, unfortunately, I didn't end up using the trailer for quite a while and didn't notice all this until after well the warranty had expired. The trailer was manufactured by a Canadian company and they claimed that, due to US regulatory restrictions, they were currently unable to ship bearings or hubs to the United States. So much for our friends to the north. Fortunately, the trailer axle was American made, and etrailer.com was able to provide me with everything I needed to make the trailer roadworthy; with higher quality parts and at less cost. And the hubs had lugs, as opposed to the originals with just threaded holes; which makes installing the wheels much easier. What can I say? I'm now a fan of etrailer.com. 25203

Switched from a 4 lug rim to a 5 lug so I could run a larger tire, already had the rims but needed to change hubs. These hubs worker perfectly, they are of good quality and are well worth the price which is very reasonable. Order processing and shipment was very fast. I have no complains at all. Any parts I need in the future will be purchased from etrailer.com. Can't beat the service or product price. I highly recommend this retailer for your needs.10673

etrailer.com did a great job, I emailed a few questions and they answered quickly. I ordered the hub over the weekend receiving an email that they received the order and it was in process, The hub shipped quickly with an email notification and arrived the next day with a second email that the package was waiting in my garage. Everything fit great and the trailer is rolling real nice now.29163
