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.


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"

I ordered a set of hubs for my trailer. The package came quickly however, one of the seals was incorrect. I called etrailer and they sent a new seal out… It arrived in two days! Awesome service.



by:

Parts do fit my boat axle.

I’m restoring and upgrading a 1980’s Dilly motorcycle trailer to make a 2800 mile road trip. The Dexter hubs with new bearings and races was a no brainer. More importantly Etrailer and their stellar customer service made this project so much easier to complete.

Great service. Great product.

After ordering from parts houses and getting expensive wrong grease seals, for my boat trailer, I found a websit e trailer, I called and talked to Jennifer, she knew what I needed right away, I ordered a hub with races, bearings, grease seals and lug nuts. Jennifer placed the order for me and with end two hours I was notified by email that my order was shipped. The third day my order was delivered to my door. No damage, was packaged very good. And was right parts. I will be using etrailer again. I recommend this co to my friends.

Still working flawlessly.



by:

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.

by:

Exactly what I needed, delivered promptly and at a competitive price point. I especially appreciated the lug pattern template to ensure what I ordered would fit the wheels I had.



by:

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.



by:

You guys are the best! Excellent service and I couldn't be happier! Thank you!



by:

Good quality hub, good price, fast shipping. Came with lugs, all bearings, inner races installed, and a double lip marine type grease seal as well as a basic grease cap. The only thing I needed to provide was a cotter pin!



by:

First of all my Customer Rep Julie H, Was very helpful and gave accurate information. A real pleasure working with her. The Hub fit as design and came to me clean and ready to go. I used this hub to retro fit a older trailer, 1960 ish. The original wheels also housed the bearing.
I would recommend this change out
I also went from an 8' wheel to 12"



by:

Great product. Perfect fit and has performed without issue all summer. These were for a boat trailer so I'm dipping them in the water constantly. They just keep asking for more.

Thanks guys. You're a life saver.



by:

Fast shipping everything listed and pictured is here and in good shape. I would have given 5 stars if the kit had come complete with a cotter pin. No fault of Etrailer as it was not in the parts list. I would just like to see a kit as a complete kit. Overall no complaints its a good deal and I hope to put many miles on it.



by:

I ordered a hub for my trailer along with another part. The 2nd part was on back order which would have delayed my order. I needed the hub for a trip. George and team were great in revising and expediting my order. Hub arrived on time, good condition, fit perfectly.



by:

Installed on my 5x8 foot trailer ,it's been towed back and forth from PA. to WI. a few times had no trouble traveling 70 - 75 MPH. 1,200 miles one way



by:

First of all, I cannot say enough good things about the people who work at etrailer. I spent at least 30 minutes on the phone with them making sure I ordered the correct hub. I recieved it 4 days after I ordered it and it fit perfectly I was able to get it installed in about 15 minutes. Thanks Etrailer!!!



by:

Very happy with everything except for that after wasting a lot of time trying to get the grease caps on and still cannot! No matter what I did would not work so they are now in the trash and I need to buy new ones. That is pretty ridiculous in my opinion. Other then that I’m very satisfied but giving this a 1 because buying the complete unit it should all assemble together without problems.



by:

nuts hards to spin on, black paint already peeling off.....F paint job, packaged very poorly, bolts taped to hub. so when i pulled off tape, off went paint. bearings are rel nice



by:

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.



by:

Trailer hub came with everything needed ; dust cap did not work out - but, used old one !! Same GREAT service and material as always !! A +++



by:

Parts arrived in 2 days & look good. All components are here, bearings, nuts cap etc. Everything looks 100% correct and will see about putting them on tomorrow. I am extremly satisfied with the on-line tech, delivery timing and cost. Thank you guys.
ps: (I put a "plug" in for you on my teardrop trailer sight.)



by:

Excellent quality hub that fits perfectly. The tutorials and videos on etrailer really assisted me in picking the correct parts for my older trailer.

Excellent communications and customer service from etrailer, too! Thank you!



by:

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.



by:

Quick Delivery, went together good, except for the Dust Covers. Could not get either of those things on to save my life. Very Thin Gauge Tin. I had another Heavier Gauge set from other hubs, they went on with no problems.

  • 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...

  • How to Determine Replacement Dexter Hubs for 2,200 Pound Trailer
    It sounds like you're measuring the bolt pattern from stud to stud. If that measurement equals 2-5/8 inches then they're 5 on 4-1/2 hubs. The 4-1/2 is the diameter of the complete circle of the studs. Since you're bearings don't have any numbers on them you can measure to find the correct hub assembly. Measure your spindles where the bearings sit or the inner diameter of the bearings using a caliper. If the measurement you get is 1.00 inches then you have bearings # L44643 and need...

  • Replacement Boat Trailer Hub with Inner Bearing L44643
    Repairing your boat trailer doesn't have to be a nightmare. I will help you to make it a sweet dream instead! You really should have both bearing numbers to ensure you get the right hubs for your trailer. The good news is you have to take the hub off anyway if you are going to replace it. Both of your bearings are likely L44643 but to be sure I would like to know the outer bearing number as well. If they are indeed both L44643 then hub # 8-258BTUC1 will fit if the wheel bolt pattern...

  • Boat Trailer Hub that Uses L44610 Races and L44643 Bearings
    Are you sure about the hub in question having a 5 on 4-3/4 bolt pattern? The only idler hub we offer that uses that race/ bearing combination is part # 34822545BX for 8-10 inch wheels or # 8-258BTUC1 for 12-15 inch wheels. Determining the bolt pattern of a wheel with an odd number of bolt holes can be a bit tricky, especially when the wheel is still in place on the trailer. The easy way to determine this is to take a measurement from the center of one bolt hole to the center of the adjacent...

    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.

  • 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...

  • Are Trailer Spindle # TRU47FR, Hub Assembly # 8-258BTUC1, and Tire/Wheel Combo # AM31985 Compatible
    The TruRyde #84 Trailer Spindle, # TRU47FR, is compatible with Trailer Hub Assembly # 8-258BTUC1. The hub assembly is designed for use on a 12 to 15 inch wheel with a 5 on 4-1/2 bolt pattern. The tire and wheel combo you have selected, # AM31985, is a match. So you will be able to use all of these components together. The hub assembly comes with the bearings, races, cap, lug nuts, and seals.

  • Will Having Larger Pilot Hole Diameters Matter on New Trailer Wheels
    Having a larger pilot diameter (center hole) on a trailer wheel is only an issue if the wheels are centered onto the axle using the hub (a hub centric wheel). In this case you would need an exact fit. You know you have a hub centric wheel if your trailer uses wheel bolts to attach the wheel instead of lug nuts. If your trailer is lug centric meaning the wheel is centered on the axle using the lug nuts, then having a larger pilot hole on the wheel is not a problem.

  • Can Trailer Hubs Replace Mobile Home Hubs
    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.

  • Replacement Trailer Tire in Size 5.30-12 for Boat Trailer
    We have replacement tires in your size of 5.30-12 like the Taskmaster 5.30R12 part # TT53012C which would work really well as it has a higher speed rating of 81 mph, is a radial, and has a weight rating of 1,050 lbs at 80 psi but we don't have any wheels like you have now that can install the way you mentioned. Since your wheels have bolts and not lug nuts that means the wheel centers on the hub and not the lug nuts a wheel with a different diameter pilot hole would not work.

  • Trailer Hub Recommendation to Fit 1 inch Diameter Spindle
    If your spindle is a straight spindle that measures 1 inch where both bearings ride you have the BT8 style spindle so for a hub with a 5 on 4-1/2 inch bolt pattern you'd want the part # 8-258BTUC1 and you'd be set. The correct Bearing Buddy would then be the part # BB1980A.

  • Why Couldnt Hub Centric Wheel Fit in Place of Lug Centric Wheel on Trailer
    It won't work because the problem typically is the bolt holes on the wheel. Lug centric wheels will have the cone shape to the bolt holes so that the matching lugs will center the wheel properly and then hub-centric won't have that same shape since the wheel is already centering on the pilot hole.
