Thoroughly Tested for Safety

This hub-and-drum assembly meets the requirements for certification by the Canadian Standards Association (CSA). The CSA creates standards, which when complied with ensure a safe and quality product. This assembly underwent extensive testing to measure stopping distances when braking. This assembly has also been tested by QAI for braking performance in a complete automotive setup and under real-world conditions to provide the most realistic scenario for the everyday driver.

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"

Install this hub-and-drum assembly on your trailer. Compatible with electric or hydraulic brakes. Fits 2,000-lb axles. Inner bearing (L44649) and race, outer bearing (L44649) and race, grease seal, grease cap, and lug nuts included.


As other reviewers have stated: getting hubs without this mystery grease would be better. All that the item description page says is that its "Lithium complex, multipurpose grease", which means that it has additives, and it's those very additives that cause problems when two incompatible greases are mixed. Consequently either that same grease has to be used for the life of the hubs or they and their bearings have got to be cleaned out so that a known grease can be used. Since calls (plural) to etrailer only produce speculation as to what grease might be compatible then that junk has to come out, with the best time to expend the non-trivial effort and dollars to remove and replace it being at installation.


Fit perfectly.


It was just what I needed and everything was included!


After one year still the trailer working good. I took my vintage HiPoint fiberglass Motocross, and added an additional pair of brakes. 2 axles, just one set of brakes from the factory as the trailer was so light, as the other axle had the mounting plate, for back up I figured it was a good insurance. Everything fit, bearings backing plates, and the drums tracked correctly behind the originals. Also added vents on both sides as there were none in it.

Working stopping without fail for the past 3 years. Good stuff.
Paul G - 06/14/2019


straight foward install, no complaints, and remember when applying the dust cap, light pressure, i dented this one :-)


They had the wrong grease seal

I will have our customer service team reach out to you. The grease seal that is included with this hub is part # 10-9
Grease Seal
which has an inner diameter of 1.50 inches and the outer diameter of 1.987 inches.
-- Etrailer Expert Jenny N - 01/25/2022


I cracked a wheel hub changing bearings and races on my pop up camper. It's a smaller hub so nowhere in town had one. I called etrailer with the dimensions and it was a perfect fit. Excellent customer service from beginning to end. Within a few days of ordering we were back on the road. Thanks etrailer!


The part was perfect and was what I ordered and delivered way before I expected…. Great service


Product arrived in excellent condition and clean. I was eligible for free shipping. Order was placed on sunday afternoon and received north of NY state on next friday. I would definitely consider buying from etrailer again.


Perfect fit


Good prices, fast shipping. Saved our t rip.


Excellent fit! I put these on my 2001 Coleman Taos pop up camper and they have worked great. And you can't beat the price!


Good quality would definitely use trailer again


5 star rating for sure , great people to deal with, and wonderful customer service...




Great price! Great shipping - free and fast - got the next day!

  • Replacement Hub/Drum that Fits 2008 Fleetwood Pegasus Ultralight Sport 718FQ
    Thanks for mentioning the axle capacity of your 2008 Fleetwood Pegasus Ultralight Sport 718FQ being 2,000 lbs. Based on that the hub/drum part # AKHD-545-2-2K is correct for it.

  • How To Add Brakes to a 2009 Forest River Flagstaff MAC 208
    The 2009 Forest River Flagstaff MAC 208 did not come from the factory with electric brakes as standard equipment. In order to add some you'd likely need the Electric Trailer Brake Kit part # AKEBRK-2 and Trailer Hub and Drum Assembly part # AKHD-545-2-1K for L44643 (1") bearings or part # AKHD-545-2-2K for L44649 ("1.063) bearings. If you don't know which bearings you have you'll need to pop off the hub and measure. In order to complete the swap you'll also need the etrailer Trailer Wiring...

  • Recommended Replacements for Dexter 8-257 Trailer Hubs
    An 8-257 hub is a 5 on 4-1/2 hub for 2,000 pound axles. They fit onto a BTR spindle which uses # L44649 for both the inner and outer bearings which have an inner diameter of 1.063 inches. If any of this doesn't match what you have let me know. If you just need the idler hubs and not the hub and drum assemblies we have # AKIHUB-545-2-LFEZ-2K that are for E-Z Lube spindles. Or use # AKIHUB-545-2-LF-2K for standard spindles. If your spindles have a zerk fitting on the end of them then...

    The nuts and lock washers needed to install a 7 inch brake assembly to the brake mounting flange is part # BRKH7 which includes enough hardware for 2 brake assemblies. I'm not certain what you mean by 'drum without a hub'. If you're talking electric drum brakes, the 7 inch hub drums we offer are one integrated piece like # AKHD-545-2-2K which uses the L44649 inner/outer bearing or # AKHD-545-2-1K which is compatible with the L44643 inner/outer bearing.

  • Replacement Hub Assemblies for Trailer with L44649 Bearings and 5 on 4-1/2 Bolt Pattern
    Both of your bearings are # L44649 and your axle is likely rated for 2,000 pounds. The correct hub and drum assembly for your trailer is # AKHD-545-2-2K. We don't carry any hubs that have a zerk fitting however you can use the standard hubs with a Bearing Buddy to make greasing them easier. I've linked our selection of Bearing Buddies for you. If you don't need the brake drum and only want the idler hub use # AKIHUB-545-2-2K instead.

  • Replacement Hubs for Boat Trailer with L44549 Inner and Outer Bearings
    I'm guessing you actually have bearings # L44649 and you either mistyped or the bearing number is difficult to read. Having # L44649 as both the inner and outer is a very popular combination on 2,000 pound axles. If you need to verify to be sure this is what you have measure the inner diameter of the bearings with a digital caliper, like part # PTW80157. It should meaure 1.063 inches. I've also done some research and found that bearing L44549 has the same dimensions as # L44649 so it...

    The Electric Trailer Brake Kit - 7" - Left and Right Hand Assemblies - 2,000 lbs # AKEBRK-2 mounts to a 4 bolt brake flange and would have a maximum amp draw of roughly 3.2 amps. These brakes do not come with brake mounting hardware so you'd want to use the Mounting Hardware for 7" Brake Assemblies # BRKH7 These brakes are compatible with the # AKHD-545-2-2K you were looking at as well.

    Seven inch trailer brake assembly # AKEBRK-2L and the matching right side # AKEBRK-2R will fit hub and drum assembly # AKHD-545-2-2K or 8-257-5UC3-EZ. Since the brakes are AxleTek I recommend sticking with the matching drums # AKHD-545-2-2K.

  • Can Trailer Brakes Rated for 2K be Used on an Axle Rated for 2.2K
    You can most certainly use the Electric Trailer Brake Kit # AKEBRK-2 with your 2,200 lb axle. Even if you are at the 2,200 lb weight capacity of your axle you will be just fine. You will also need to swap out your idler hubs for hub and drum assemblies. If you have an EZ Lube spindle use part # AKHD-545-2-EZ-2K but if you would like the standard grease cap use part # AKHD-545-2-2K instead.

    The Electric Trailer Brake Kit # AKEBRK-2 along with the Hub # AKHD-545-2-2K and Axle # ASR2000S01 will all give the 10"-13" wheel size as those are the wheel and tire sizes that have the similar weight ratings for the components. By using larger wheels and tires that have higher weight capacities the tires are to stiff and rather than absorbing road shock it transfers that to shock to the hub and spindle.

You'll also want to examine the armature surface of the brake drums where the brake magnet rides. If this surface is pitted and/or has grooves worn in it, you'll want to replace the drums as well.
