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.
If D = 2-5/8", then the bolt pattern is 5 on 4-1/2"
If D = 2-3/4", then the bolt pattern is 5 on 4-3/4"
If D = 3", then the bolt pattern is 5 on 5"
If D = 3-1/4", then the bolt pattern is 5 on 5-1/2"

Video Transcript for Dexter Trailer Hubs and Drums 8-258-5UC1 Review
Today were going to review part number 8-258-BUC1 this is the Dexter Trailer Hub Assembly for 12-inch to 15-inch wheels with the 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 the inner and outer bearing both the same part number of L44649. It will include the grease cap and the grease seal, part number 10-9 and the bearing races are already installed in the hub assembly. There is the outer bearing race. Theres the inner bearing race.
Most all our hub assemblies we do preinstall the bearing races in them. The application on this hub assembly is 2000-lb axles. The capacity on this hub assembly is 1250 lbs so when this is paired with one on the other side of the axle would give you your maximum weight capacity of 2500 lbs. This does have a bolt pattern of 5 on 4-1/2. Now it also has a hub flange, which is this whole section here, the diameter of it is 6-1/2 inches.
So that will allow you to use 12-inch to 15-inch wheels with this hub assembly. Now when I mentioned the bolt pattern, the way to measure that on a bolt pattern that has an odd number of lugs which in this case would be five, is you would measure from the center of one wheel stud to the center of a wheel stud right next to it. That would be 2-5/8 inches and that would make this a 5 on 4-1/2 inch bolt pattern. The way you can tell that is if you go to the product page for this part number at the bottom of the page will have a table that will show you when take this measurement from stud to stud across from each other, if its 2-5/8 it will mean its a 5 on 4-1/2-inch bolt pattern. Now some axles that are rated at 2000 lbs like this one will require a different seal and bearings.
Be sure that the bearings in the hub youre replacing have the L44643 stamped on them. If they dont, if they have the L44643 then you need to use a different like part number hub assembly which would be 8-258-BTUC1. That should do it for our review on part number 8-258-BUC1.

Acceptable quality, fit my trailer just fine, easier than trying to get the original bearing races out of my old rusty hub. Comes with the bearings, seal, and lug nuts, but no cotter pin. Seems like that would be obvious and it could cause an unexpected trip to the hardware store if you don't have some available.80095
I rec my hubs today and installed same. Thank you for such quick delivery. I like the 'tracking' as well--makes it ez to plan ahead.
Installation tip: I had trouble installing the cups,so I inserted the cup backwards in the old hub,then placed open cup against new hub and tapped w/ hammer and it went right in,no problem because equal pressure all around!! :)) I used the old hub as a tool.59829
Price was reasonable and they fit and perform well. I used these to upgrade an oddball 5 on 4.25 bolt pattern 2000lb axle to the more common 5 on 4.5 pattern. The hubs essentially paid for themselves in the decreased cost of replacement tires and wheels (would have to have had tires mounted/balanced locally which greatly increased the price).49186
The hubs installed in about an hour for both sides. Everything was included and races already installed. The only thing I wish the kit provided was a tang washer. I'll be buying another to keep as a spare on the trailer.36839
I received the replacement hubs in a timely manner. They appear to be well made. The etrailer web site was easy to use and the check out process is better than others I have used. I will shop at this website again.34426
A great product at a great price! The additional material explaining the right way to choose the right drawbar was very helpful. Fast delivery helped me get back on the road. Super Customer Service!20559
Hubs are in nice shape, I like the fact that they dont come greased as I would have no clue what grease was used in them. Please take note however if you are replacing marine hubs like I was that you will need to order two seperate double lip seals. I actually had to order a second time because I noticed that I couldnt hold any hub pressure on my ezlube hubs. Note that I knew from the get go that I needed different caps.
I would like to see this same hub offered in a marine package or a warning that this is only a single lip seal.
Its however not a deal breaker, I will order a third knowing what I know now to have a travel backup.70663
Sent two different seals both of which were the wrong size. One of the seals was too dented to use even if it had been the correct size. One set of bearings was the wrong size. Packaging was very unprofessional with the bearings, seals, lug nuts, and dust caps taped to the hub with packaging tape. Package did arrive on time but could not be used. Customer service was good and we are awaiting a refund.70421
Trailer hubs have two bearings, one is referred to as the inner bearing, closer to the trailer. The outer bearing is the one furthest from the trailer. If we have both of these bearing numbers we can identify which spindle or hub is needed.
So far you have L44649 as your outer bearing and L44610 as your outer race. We carry 8 hubs that use outer bearing L44649. Your inner bearing should either be another L44649 or an L68149. Once you provide us with the second bearing number, I can provide yo view full answer...
You have already done the hard part, which is getting the bearing numbers. With those numbers and the bolt pattern you have provided, we have 2 possible hubs that could work as replacements, depending on the trailer wheel size.
If your trailer has 12 inch to 15 inch wheels, then you can use the Trailer Hub Assembly, # 8-258-5UC1, that you have referenced.
If your trailer has 8 to 10 inch wheels, you will need Trailer Hub Assembly # 8-259-5UC1. view full answer...
The best way to determine which hub assembly you will need is by the bearing numbers. The item you selected, Trailer Hub Assembly, part # 8-258-5UC1, is a replacement hub which uses Inner and Outer Bearing # L44649. The bearing numbers will be stamped or lasered onto the flat back side of the bearings.
The other things you will need to determine are the bolt pattern, the size of your trailer wheel, and the axle capacity. Part # 8-258-5UC, is compatible with a 5 on 4-1/2 bolt pattern. I have l view full answer...
For an idler hub I would recommend that you get a Trailer Hub Assembly, part # 84545BX. This hub has the same inner/outer bearings and seal size as your current hub so it would work well for you.
For a brake hub I would recommend that you get a Trailer Hub & Drum Assembly, part # 84557UC3.
Both these drum assemblies use the same bearing and seal size that came off of your old hub, so this will work on your spindle perfectly. view full answer...
It sounds like you might have an older agricultural hub and spindle on your trailer based on the LM11749 bearing that you referenced as I can not find any information on hubs with that bearing number.
I am going to send you a separate email that is going to have a picture of a spindle with measurements on it. If you could use a dial caliper and give me those measurements I would be able to know for sure if there is a hub that I could recommend for you. view full answer...
The best way to determine the correct replacement hub assemblies for your trailer is to retrieve the bearing numbers stamped into the metal of both the inner and outer bearings. With those numbers, we can find which hubs would be a correct fit. I am including a link to a video that will show you how to remove, inspect, and reinstall trailer bearings, races, and seals.
I have the Dexter Trailer Hub Assembly, part # 8-91-05UC1 which has a 4 on 4 bolt pattern. It uses the TruRyde Bearing, part # view full answer...
For your inner bearings and grease seals, if the reference number cannot be located, having an accurate measurement of both the inner and outer diameter of the bearing and seal will be very helpful in finding a replacement. A digital caliper is called for, as a ruler or tape measure will not give an accurate enough measurement.
If you can reply with the measurements, I will find replacements for you.

For a hub with a 5 on 4-1/2 inch bolt pattern you would want a Trailer Hub Assembly # 84545UC1-EZ. This hub uses a # L68149 as an inner and a # L44649 as an outer.
For a hub with a 6 on 5-1/2 inch bolt pattern you would want a Trailer Hub Assembly # 84655UC1. This hub uses a # L68149 as an inner and a # L44649 as an outer.

The bearing races on a trailer hub, like the Trailer Hub Assembly, part # 8-258-5UC1, are removable, they are not built into the hub. I am including a link to a FAQ page on wheel bearings, races, and seals. Also, a link to a video of removing and reinstalling bearings, races, and seals. It will show, starting at the 2 minute and 5 second mark, how to remove a bearing race.
You might also try to rent from an auto parts store a bearing/race removal and installation tool, or you might see if the view full answer...
To determine if we have a wheel bearing that will be compatible, you will need to use a digital caliper and take some measurements of your existing spindles. If you reply with the B, C and D dimensions you find (as shown in the diagram I provided), I would be happy to try to find hubs that would be compatible with your bearings. view full answer...
To find the correct hub for you, I will need to know the wheel bearing numbers or an accurate measurement of the spindle with a digital caliper. I will also need to know the bolt pattern of the hubs you are replacing.
The cages that the wheel bearings sit in should have a reference number stamped on the back of them (see diagram). I will also provide you a diagram showing where on the spindle the measurements need to be taken.
You will also want to make sure that your spindles are still in view full answer...
We offer two different 5 lug 4-1/2 bolt circle idler hubs for 2000 lb axles, one that uses the L44649 bearing that has a 1.063 inside diameter and the other uses the L44643 bearing that has a 1 inch inside diameter.
The # 8-258-5UC1 hub you are using has the L44649 bearings, which have a 1.063 inside diameter, you would need the # 8-258BTUC1 hub. Unfortunately, the bearings are NOT interchangeable between the two hubs and you will need to replace the hubs with the # 8-258BTUC1. view full answer...
On some wheel and hubs the center pilot hole has to be the exact size of outer hub bore. This is because the wheels are hub centric meaning they center on the hub rather than the lug holes. Hub centric wheels and hubs will use wheel bolts and not lug nuts.
If the wheel centers on the hub using lug nuts (the studs are mounted in the hub) then having a larger pilot hole on the wheel is fine. view full answer...
We have several trailer hub options with the 5 on 4-1/2 bolt pattern and bearings L68149 and L44649. For an idler hub there are 2 options. We have a standard hub, # 84545BX, which includes the bearings, races, seal, grease cap, and lug nuts.
There is also an EZ lube version of the same hub if you have an EZ lube axle. It is # 84545UC1-EZ. It also includes the bearings, races, seal, grease cap, and lug nuts. view full answer...
Since your existing wheels use lug bolts instead of lug nuts, we refer to them a hub-centric rather than lug centric. A lug centric wheel is supported the wheel studs, which means that the studs not only function to keep the wheels in place, but they also bear the vertical load of the trailer.
In contrast, with a hub-centric wheel, the lug bolts hold the wheel in place, but the vertical load of the trailer is primarily supported by the portion of the hub that passes through the pilot hole of view full answer...
From what you describe, you might very well use the # 8-258-5UC1 hub you referenced, but we will need to be absolutely sure. In order to suggest the correct hub, we will need some additional information from you.
- Bolt pattern of your existing hubs (see FAQ article to determine your bolt circle dimension)
- Since your bearing reference numbers are unobtainable, you will need to take some accurate measurements from your spindle using a dial or digital caliper at the inner bearing surface, ou view full answer...
To determine the size of the hub assembly you need to purchase you have to determine which bearings are in the old assembly. If the old assembly has L44649 inner bearings, you would use the hub you chose # 8-258-5UC1. If the inner bearings are marked L44643, you will need # 8-258BTUC1. If you do not have the old bearings, you need to measure the inner bearing surface on the spindle to determine if the 1.063 inch dimension or 1.00 inch dimension will be needed to accept the bearing.
