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.


Bolt Pattern - Even

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.)


Bolt Pattern - Odd

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.)


Bolt Pattern Side

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"

  • How to Determine Correct Hub For Harbor Freight Trailer For 13 Inch Wheel
    Hello Andrei, There isn't an axle we can offer as there aren't any that small we have, but you may be able to get a different hub. I couldn't find the bearing sizes of that axle to find a new hub so you'll have to do a bit of measuring. For that you will need to take apart your current hub assembly and look at the bearings themselves; wipe away the grease and you should be able to see the part number stamped directly on them. If you are unable to find them, you need to use a digital caliper...

  • Recommended Replacement Axle For Axle With Obsolete L44649 and LM11949 Bearing Combination
    I have a replacement axle option for you, but unfortunately we do not carry a hub that uses inner bearing # L44649 (1-1/16") and outer bearing # LM11949 (3/4"), and I was unable to find such a hub from any other vendors. The best option is going to be replacing the axle with one that uses a more common bearing combination to make finding replacement parts now and in the future easier. Based on the bearing combination you have your axle is more than likely a 2000lb axle but you will want...

  • Are 15 Inch Wheels With a 5 on 5 Bolt Pattern Available?
    You have come to the right place, because we have a number of 15 inch wheels with a 5 on 5 bolt pattern. Other sizes are more prevalent, such as the 5 on 4-1/2 you mentioned, but there are options for you. The most popular of these we offer is the Dexstar Steel Mini Mod Trailer Wheel # AM20538DX. You can see how the Dexstar look on a trailer in the photo I've attached. If you were more interested in white spoke wheels, those are also available. The most popular of this style we offer...

  • How to Determine the Size of a Trailer Hub Assembly for Replacement
    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. You...

  • What is The Outer Diameter of The Dexter Trailer Idler Hub Assembly # 8-258BTUC1?

  • Fit of Wheel Mounting Pad on Face of Trailer Hub
    Hi, it looks like you are using a hub centric wheel with a lug-centric hub. A hub centric wheel relies on the portion of the hub that extends through the wheel's pilot hole to provide the support. In this instance, it's not super-crucial that the mounting pad of the wheel sits perfectly flat against the hub face. With a lug centric wheel, it's VERY important that the wheel sits perfectly flat. Long story short, I would NOT use that wheel on that hub. For a 12 inch wheel, I'd use something...

  • Replacement Hub for Big Max Utility Trailer
    Hi Bryce; that information narrows it down but there are still two possible hub replacements with different bearings. The # 8-258-5UC1-EZ has # L44649 inner and outer bearings with a 5 on 4-1/2 bolt pattern. The # 8-258BTUC1 has # L44643 inner and outer bearings with a 5 on 4-1/2 bolt pattern. You will need to either pull your hubs and check your bearings to see what you have, or use the serial number off the axle tag to identify it. If you have a 4 on 4 bolt patter you can use # 8-91-05UC1-EZ...

  • Correct Hub Assembly for Dexter 8-258 Hub and 13-Inch Wheels
    With axle 8-258, your bearings are either # L44643 or # L44649. # L44643 bearings have an inner diameter of 1 inch, while bearings # L44649 have an inner diameter of 1.063 inches. You can locate the bearing numbers on the bearings themselves, or you can measure the diameter using the image I've attached. We offer two hub assembly kits with # L44643 bearings. Item # 8-258BTUC1 is the standard hub assembly kit, which includes lug nuts, inner bearings and race, outer bearings and race, grease...

  • Bearings and Seal Recommendation for Dexter 3,000 lb Axle
    Thanks for the picture of the tag on your Dexter trailer axle. From that I can tell you have a 3,000 lb Dexter axle. There isn't a kit available, but I was able to find each of the components you need, which are available individually. You will need bearing # LM67048 and matching race # LM67010, along with bearing # L44649 and matching race # L44610. For a grease seal you need # 58846, along with grease cap # 21-41-1 and cotter pin # 165649. For replacement brake assemblies you'd then...

  • Replacement 5 on 4 3/4 Hub With LM67048 Inner Bearing and LM11949 Outer Bearing
    With your hub having an inner bearing # LM67048 and outer bearing # LM11949, it sounds like you have an agricultural style hub, like the Redline Trailer Hub Assembly # AH15450ECOMP. However, this will have a 4 on 5 bolt pattern and this will be the only bolt pattern this hub is offered in, unfortunately. With that being said, the best option we can recommend will be to replace your axle with something that uses more common parts. Though you will need to measure a few things, picture included,...

  • Can 15 inch Wheels be Used with a 2,000-lb Trailer Axle
    It doesn't necessarily have to do with the axle-to-wheel size as much as it does the hub-to-wheel size. Most, but not all, hubs rated for a 2,000-lb axle are compatible with smaller wheel and usually have an 8" - 12" wheel range. As you found, sometimes that is not always the case. The part # 8-258BTUC1 that you referenced is compatible with 13" - 15" wheels that have a 5 on 4-1/2" bolt pattern. If this hub fits your axle and your wheel is compatible with it then you can definitely use...

  • Idler Hub Assembly for 2,000 lb Axle With 13 Inch Wheels
    We do have a solution for you, although the Dexter Trailer Idler Hub Assembly for 2,000-lb Axles # 34822545BX does require wheels be only 8" to 12". The reason for that is there is this hub does not have a large enough flange diameter in order to to provide the necessary side-to-side support for a larger 13" wheel, so it can become loose on the hub. Instead, the hub you need for your 13" wheel is the Dexter Trailer Idler Hub Assembly for 2,000-lb Axles # 8-258BTUC1. This uses the same...

  • Replacement Bearing Kit Recommendation for a Coleman Fleetwood Santa Fe 1999 8-258 Hub
    The biggest clue for determining what bearings you need came from the last number you listed. Thank you for that! You have basically the part # 8-258BTUC1 hub and the correct bearings would be the kit part # DL21792 that comes with the correct bearings, seal, races and cap.

  • Recommended Spindle And Hub Assemblies For 1-1/2 Inch Square 2,000-Lb Axle
    The spindle that you referenced, part # TRU47FR, will work great for you. This spindle features a 4 inch long stub, and is rated for a 3,500-lb axle. I have attached a link to a product review video for this spindle you can check out. The installation of this spindle should be done by a qualified professional welder because it is important that the spindle is welded in place as square and concentric as possible. The hub assembly designed to work well with the TRU47FR spindle is part #...

  • Recommended Trailer Hub with 1-1/4 Diameter Inner Bearing and 3/4 Diameter Outer Bearing
    To recommend the correct hub drum for your application, I would need to know a little more information. First I will need to know your current hub bolt pattern. In order to determine your hub drum bolt pattern, you would need to measure center to center on bolts directly across from each other on the circle. If you have an odd number of bolts, measure from the center of any bolt to the point halfway between the two bolts directly across from it on the circle. The first number of your...

  • Replacement Hub For A Trailer With A BT8 Spindle
    For a replacement hub that uses # L44643 bearings with a 5 on 4.5 bolt pattern you'll want the Dexter Trailer Idler Hub Assembly # 8-258BTUC1. This will come as a quantity of one so you'd need two kits to do both sides of the axles. Each kit will come with the bearings, races, seal, grease cap, wheel bolts, and lug nuts included.

  • Trailer Hub that Fits 1 inch or 1-1/6 inch Diameter Spindle
    We have hubs that are designed to fit spindle diameters that you mentioned of 1 inch and 1-1/6 inch. If you have a straight spindle with a 1 inch diameter you'd have a BT8 spindle and the hub part # 8-258BTUC1 that you referenced would fit. If you have a spindle with a straight diameter of 1-1/6 inch then you'd have a BTR spindle and would want a # 8-258-50UC1. The diameter of the spindle where the seal would ride on either would be 1.25 inch. If you can verify your spindle dimensions...

    Most likely the axles/spindles on your boat trailer have are obsolete. But there is a chance you could have an agricultural hub like part # AS3000F as this has a 3/4 inch diameter portion at the very end of the spindle. To see the dimensions of the hub to compare to yours check out the picture I attached. You will want to use a dial caliper to get exact measurements of your spindle to compare to this one. Unfortunately none of the hubs we offer that would fit this spindle have a 5 on...

  • Availability Of Replacement Hub For Older Axle W/ L68149 and LM11949 Bearing Combination
    I have a replacement axle option for you, but unfortunately there are not any hubs currently produced that use inner bearing # LM67048 (1-1/4" I.D.) and outer bearing # LM11949 (3/4" I.D.) and have the 5 on 4-1/2" bolt pattern. If your current hubs are still useable I recommend just replacing the bearings and sticking with them as that will be the most cost effective, though you will need to use wheels with the 4 bolt pattern. If the hubs are damaged and cannot be removed the only option...

  • How to Remove a Hub From a Trailer Spindle
    To remove a hub from an axle, you will need to first remove the grease cap on the end of the hub. This will expose the end of the spindle. Once at this point, you will need to see if you have an EZ-Lube spindle, like # TRU77FR, or a standard spindle, like # TRU57FR. If you have the standard spindle, there will be a castle nut threaded onto the end of said spindle that is locking a fairly large washer in place. This will be locked in place by a cotter pin, like # 165649. These will all...

The easiest way to find the right replacement is to check the numbers on the hub components as noted in the attached photo. We can then find the correct hub that is designed to work with that specific bearing, race, and seal. If you are unable to find the numbers on the parts, you will want to use...

    I am almost certain that the bearings you have, if both the same, are # L44649 bearings with a 1.063 inner diameter. What I really need to know at this point is the inner diameter of the seal, not the outer. Using a set of digital or dial calipers will provide and accurate measurement. You can also measure the spindle with the calipers. I will need the measurements shown in the picture I have included.

    To positively determine if you can change your mobile home hubs with trailer hubs we will need to see if a trailer hub will fit your spindle. To determine this you will need either the bearing and seal part numbers from the bearings and seal on the spindle, or you can take some precise measurements to find the inner diameter of the bearings and seals. That being said, often times you will not be able to find replacement parts for a mobile home axle as they are designed for one time use...

If you do not have the old bearings, you will need to measure the spindle on your trailer to determine the size bearings that you will need, and what hub assembly will work.
