Bearing, Race, and Seal Information

- Inner race: L44610
- Outer race: L44610
- Grease seal (included): 34823

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.
- 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.

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.

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.

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.

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: Catherine Thompson09/12/2013
You guys are the best! Excellent service and I couldn't be happier! Thank you!
by: Norm04/22/2015
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: Uncle Joe11/04/2014
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: Kevin C.09/08/2017
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: Kevin04/27/2016
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: becky07/12/2013
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!!!

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: Warren06/01/2018
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: Billy D03/29/2011
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: George03/05/2018
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: Dennis D03/17/2015
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: Greg03/07/2013
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: Brent 08/23/2022
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: Raven 01/09/2014
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: timbo05/16/2013
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: Gerry R.06/26/2015
Just what I needed. these will be used on a trailer that will be pulled by a Jeep Wrangler TJ Sahara.
THANKS GEORGE
by: L. Lane09/04/2014
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.

- 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.

view full answer... - How to Pick Out Bearings for a TrailerI really wish there was a way to determine what bearings a trailer needed without actually pulling the wheel off and checking, but there isn't. The only two solution I have for you would be to remove the hubs and get the numbers that are stamped on the bearing or for you to remove the hubs and use a digital or dial caliper to measure where the bearings and seal ride (see pic). With that info I can help you figure out what you need. The best grease to use in a hub assembly is the "red"...

- Availability Of Replacement Hub For Older Axle W/ L68149 and LM11949 Bearing CombinationI 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...

- Idler Hub Assembly for 2,000 lb Axle With 13 Inch WheelsWe 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...
view full answer... - Can 15 inch Wheels be Used with a 2,000-lb Trailer AxleIt 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...
view full answer... - Hub Availability to Fit Spindle with 1 inch Diameter Where Bearings RideCan you verify the diameter of the spindle where the seals ride too? If that diameter is 1.24 inches combined with your bearings both having inner diameters of 1 inch we would have hubs that would fit. The part # 8-258BTUC1 would give you a 5 on 4-1/4 inch bolt pattern hub that fits.

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...

Since the hubs we offer can vary per the bearings and races and seals they fit you will want to make sure you get the correct replacement.

- Correct Hub Assembly for Dexter 8-258 Hub and 13-Inch WheelsWith 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...

- How to Remove a Hub From a Trailer SpindleTo 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...
view full answer... - Recommended Spindle And Hub Assemblies For 1-1/2 Inch Square 2,000-Lb AxleThe 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 #...
view full answer... - How to Determine Correct Replacement Hub for R-Vision TrailerI can tell you how to determine the correct replacement hub for your 2010 R-Vision Trail-Lite Crossover TLX170T, though based on the photos I looked up, this is a tandem axle trailer so it won't have 3,500 lb axles, and it is far more likely you have 2,000 lb axles. To determine the correct replacement hub you will need to know what bearings your current hub has. You will need to take apart your current hub assembly and look at the bearings themselves; wipe away the grease and you should...

- Replacement 5 on 4 3/4 Hub With LM67048 Inner Bearing and LM11949 Outer BearingWith 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,...

- Recommended Trailer Hub with 1-1/4 Diameter Inner Bearing and 3/4 Diameter Outer BearingTo 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...
view full answer... - Why Couldnt Hub Centric Wheel Fit in Place of Lug Centric Wheel on TrailerIt 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.

For # L44649 inner and outer bearings you need part # 8-258-5UC1 while you will need part # 8-258BTUC1 if you have # L44643 inner and outer bearings. Since these hubs are already compatible with a 15" wheel and they have a 5 on 4-1/2" bolt pattern (which is the most common) you actually have a variety of choices when it comes to wheel/tire combos.

- Will 2K Dexter Trailer Idler Hub Replace Hub Using L44643 BearingsYes it sure will; since both your inner and outer hub use # L44643 bearings, so long as your axle is a 2,000 axle to meet the rating of the hub, you can use the following Dexter hub as a replacement: - Dexter Trailer Idler Hub Assembly for 2,000 lb Axles - 5 on 4-1/2 # 8-258BTUC1
