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"

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 L44649 stamped on them. If the bearings have L44643 stamped on them, use 8-258BTUC1 trailer hub.

Note: Trailer wheels that are smaller than 15" and have 5 bolts, have a 5 on 4-1/2" bolt pattern.

Very happy with etrailer, they where very easy to work with and stand behind there parts, will always use them for all my trailer parts, had a piece missing and they called me right back and solved the problem fast, love that,thank you etrailer


Good product and fast shipping. Customer support was great, I couldn't find what I was looking for made a call to etrailer and they found what I was looking for.


Purchased for spare hud, matches perfect


perfect fit, now the boat can get to the lake again!!! dont forget to order the castle nut kit parts came in when they said they would, will be my go to guys for trailer stuff in the future


Was rebuilding a jet ski trailer to carry a kayak. I order several parts to include these new hubs. The hubs were great, but the seals were to large for my spindles. Talked to customer service and they shipped me new seals for no additional charge!



The product is great. Customer service was incredibly helpful making sure I got the right equipment. Ive had it over a year and it is functioning perfectly.


I bought a bearing kit for my utility trailer. Parts arrived on time and the cost was considerably expensive than what I found locally. After a year of use, all is well! The trailer is used continuously and I have had zero problems with the new bearings.



Still going strong! The past last year has a typo that I should have caught. The product was considerably LESS expensive from Etrailer than what I found locally. Sorry


This hub assembly was exactly what I needed to update/upgrade my trailer. No missing pieces, which is always a plus. This assembly and some axle grease lengthened the life of the trailer. Another DIY project completed and in use.

I used the trailer w/new hubs for about 5 months. I then had a person interested in the trailer, for the right price, so I sold it.Thank you for the inquiry.


Came with surface rust on the bearing races. Polished them up we will see how the last. Great customer service and delivery.


My original hub cracked after I tried to install a replacement wheel bolt. Went up to E trailer and found the replacement hub VERY easily. Their tutorial video also clarified which wheel bearing I should have since the same hub is used in two different weight classes.

UPS ground package came in two days, way ahead of what I was expecting.

It was easier and faster than trying to locate in my area that could order it for me.

This is the second time I have purchased items from E trailer and have nothing but praise for their efforts.


Hi I’m happy with the product not happy with the packing you guys just through the hubs in the box no packing to stop them bouncing around The metal covers they go on the outside of the hub or bent so I’m over here trying to bend them back to get them on the hub

I will have our customer service team reach out to you.


The item was exactly what I ordered. My only concern was that the tires I had on my trailer were 13", and the hubs are labeled as for only 8 to 12" wheels. It didn't make any difference. It was the exact part and replacement that I needed using the old part number scribed into the back of the old hub. Thanks for a great match!


received the Dexter Hub ready for complete installation. Seems like a good value but havent installed it long enough to make any comment about the quality. The original hub stripped 4 of the 5 wheel studs when I tried to remove the wheel , and had to grind the back of the studs off to get the wheel seperated from the hub.


I bought a bearing kit for my utility trailer. Parts arrived on time and the cost was considerably expensive than what I found locally. After a year of use, all is well! The trailer is used continuously and I have had zero problems with the new bearings and hubs.


I have a relatively lengthy trip coming up and wanted to have a spare hub with me should a problem develop in route. The offering was comprehensive but I did elect to remove an existing hub to be assured that I knew the actual bearing ID's. That done, selecting the right hub was easy. The price appeared appropriate and I placed an order. The hub was delivered ahead of schedule and in good condition. My only concern is that the hub and bearings were delivered without having been pre packed with grease. Not a deal breaker but it would have been nice. I will likely buy another hub in the spring.


Fit my seadoo boat trailer perfectly. The video on the page was very helpful and the parts a great quality. Dust cap was un useable because it was damaged (possibly from shipping ) the only thing that would make this kit better is if it was pre greased and came with a new pin.
Overall I'm very happy with it. Shipping came exactly the day they said even in a rain storm. Had updates along the way .
Will definitely use them again in the future for all my trailer needs !


Hub fit perfect and it was nice that both race's were already installed in the hub. Replacement went smoothly. Bearings fit my axle smoothly unlike a set of bearing I purchased at an automotive store.


i was impressed with the speed that my order arrived. The tech was very helpful when the order was placed. I was disappointed that the bearing buddy was only a metal cylinder and did not contain a spring and zert fitting for continuous greasing. One of the packages was missing a black dust cover. One of the so called bearing buddies was bent. One of the spindles had a three eights inch area that was not polished. It looks like a tool broke during manufacturing or a possible defect during the pouring process.


Product looks good, shipping was very fast. etrailer was very easy to work with. The instruction video lacked a bit of detail regarding how hard to tap in the inner grease seal (first hub I've ever replaced). I'm still a bit unclear on this...


This was my second order with etrailer. Ultimately pleased with the product on both occasions, however, one of the bearing shipped looked like someone smashed it with a hammer.

I'm sure etrailer would have taken care of me had I made a complaint, but I just used an old bearing from the original hub. Problem solved.


Hub itself is well made. Accompanying bearings are made in China. Races pre-installed. One race had a rusty nodule and left a rusty pit when removed. Out with the crap and in with Timkens. Price is great, but I suspect some would be willing to pay more if it came w/ Timken or SKF bearings.


Product was delivered on time with no defects. But the best thing was the technical support that was provided. I have made many more purchases after this one and will always be the first place that I shop for trailer parts


Trailer Hub Assembly's and wheel tire combo's were shipped extremely fast and everything looks perfect to replace badly rusted and worn parts on my snowmobile trailer.


I recently needed tires for my snowmobile trailer. The selection I found at Etrailer was excellent with great prices. I ordered the tires on Saturday night and was amazed to see the tires show up on Tuesday morning. The communication was great too. This is a great company to deal with. I look forward to another purchase.


Excellent delivery time, hubs and accessories fit perfect. Installed and been using the set for a year with no issues. Thanks for the service with your company!!!!


Ordered idler hubs on a Wednesday and they were on my porch Thursday afternoon. Tim M upgraded my shipping at no extra charge. Parts fit great, I won’t have to worry about bearings anymore.

  • Bearing Reference Number or Spindle Dimensions Needed to Choose Replacement Hub
    The best way to provide the correct hub for your spindles is to compare the bearing numbers. Check your existing inner and outer bearings for their reference numbers (see photo). With those numbers, I can recommend the correct idler hub for you. If you cannot find the bearing number, we can still recommend the correct hub if you supply us with some precise measurements of the bearing and seal surface of your spindle. See picture.

  • How to Select Hubs That Are Compatible with Trailer Spindle
    To choose a compatible hub assembly for any spindle the key is knowing the inner and outer bearing part numbers, or if they are not available, precise dimensions of the spindle at the points where the bearings and grease seal ride. These points on the spindle are noted on the diagram I linked for you. Once you know the bearings this will tell you which hubs will fit properly. You also need to select hubs based on the weight load that will be put on them. It appears you have a fabricated...

  • Where To Find Numbers For Replacement Bearings On Utility Trailer
    Since the axle you have is a Dexter Model 8259 you can choose one of the hub assemblies we offer from the attached product page. If you have an EZ-Lube axle on your trailer you may want to check out part # 8-259-5UC1-EZ, or part # 8-259-50UC1-EZ. If you do not have an EZ-Lube axle take a look at part # 8-259-5UC1 or part # 8-259-50UC1. I have attached links to some product review videos for these kits you can take a look at.

  • Replacement Trailer Hub for Dexter 8-259 Idler Hub
    We will need to go by the bearings used in your current hub. If your bearings are L44649 inner and outer then you can use hub # 8-258-5UC1-EZ. It and hub # 8-259-5UC1-EZ use the same bearings, both have a 5 on 4-1/2 bolt pattern, and both are for 2,000 pound axles.

  • Hubs for 13 Inch Tire with 5-1/2 Hub Flange Diameter
    I spoke with an engineer from our hub manufacturer, Dexter, and they do not recommend using a hub for 8-12 inch wheels with a 13 inch wheel. However, they said that they do not make a hub for 13 inch wheels that has a hub flange diameter of smaller than 6-1/2 inches. The best option that we can recommend is to replace your wheels to fit the hubs we offer. The hub designed for smaller tires with a smaller hub flange will technically fit but, there may be no warranty support if something...

  • Measurement Of Dexter Trailer Hub Assembly # 8-258-5UC1
    The Trailer Hub Assembly # 8-258-5UC1 measures 4-1/4 inches from front to back. As long as you have the length on your spindle, you won't have any issue. That measurement is not including the grease cap, it is just the hub from edge to edge. There is 2 inches on either side of the hub face which is 1/4 inch thick.

  • Which Hub to Use for 2,200 lb Dexter Axle 8-258 or 8-259
    Thanks for the pictures. Either part number hub is going to fit your hub since they both have the same bolt pattern and bearings. The difference is going to be based on the diameter of your trailer wheels. If you have 13-14 inch diameter rims you would want the part # 8-258-5UC1. If you have smaller wheels that are 10-12 inch you would want the # 8-259-5UC1-EZ. The difference is the size of the wheel mounting flange.

  • Determining Which Replacement Hub Needed for 2001 Yacht Club Pontoon Boat Trailer
    In order to recommend the correct replacement, I'll need to know whether you're looking for an idler hub (no brakes) or a hub/drum. I'll also need to know the reference numbers from the inner and outer wheel bearing. If you can't find the reference numbers or if they aren't readable, you'll need to use a highly accurate measuring device to measure the journal surfaces of the spindle where the inside diameter of the bearings ride. For instance, the # 8-259-5UC1-EZ idler hub is compatible...

  • Adding Larger Wheels to Trailer Hub Assembly with Same Bolt Pattern
    You can add larger wheels to a trailer as long as you have the same bolt pattern and enough room for the larger size. The main clearance issues we find when putting larger wheels on a trailer is from the top of the tire to the fender and from the inside wall of the tire to the trailer wall/frame. Also you will want to keep the weight capacity in mind. Larger tires will typically have a higher weight rating. Tires with a higher weight rating will not increase the load carrying capacity...

  • How to Pick Out Replacement Hubs for a Trailer with 1980 Bearing Buddy
    The 1.980 Bearing Buddy is very common on hubs that have L44649 bearings inner and outer like the part # 8-259-5UC1-EZ for a 5 on 4-1/2 inch bolt pattern hub or part # 8-91-05UC1-EZ for a 4 on 4 inch bolt patter. However, your best option would be to remove the hubs and use a digital or dial caliper to measure where the bearings ride. If that dimension is 1.063 then either of the hubs I mentioned would work well for you as that would mean you have the BTR spindle.

  • What is the Largest Size Can I Upgrade My Trailer Tires To?
    When upgrading a tire size you always want to consider tire clearance. The actual distance between the inside of a tire and the frame rail depends a lot on the setup of the trailer. But as long as the tire and the frame don't touch you would be fine. You should have at least 2-3 inches from the sidewall to the trailer and at least 4 inches from the tread to the underside of the fender. You will need to take the measurements of the larger tires to measure and compare in order to ensure you...

  • How to Determine Correct Trailer Hub
    It's possible we have a hub for your TeeNee trailer, though we don't have any way of knowing off-hand or cross-referencing what hubs you need. So in order to find the correct hubs 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 and measure your spindle where the bearings ride, like in the...

    Based on the C and D dimensions you listed you have a BTR spindle. The correct idler hub with a 5 on 4-1/2 inch bolt pattern that you would need would be the Trailer Hub Assembly # 8-259-5UC1-EZ. If you needed a hub and drum assembly for your spindle you would need the Trailer Hub and Drum Assembly # 8-257-5UC3. The # 34822545BX would not work on your spindle dimensions.

Then if you need a 5 on 4-1/2 inch bolt pattern instead you'd want the part # 8-259-5UC1-EZ.
