E-Z Lube-Compatible Assembly for Simple Lubrication

The grease cap on this hub-and-drum assembly is specially designed to work with your Dexter E-Z Lube axle to make lubricating bearings quick and easy. Just remove the plug on the grease cap, attach a grease gun to the zerk fitting on the end of the spindle, and inject the grease. It will flow easily to both inner and outer bearings. Not only does this make lubricating the bearings easy, but it also helps to prevent corrosion of the hub. This is because you can lubricate the bearings without the mess of taking apart the entire assembly.

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 was a bit intimidated by the thought of taking apart my hubs and had no idea where to start. But the etrailer live chat gave me a complete parts list based on my trailer GVWR, I watched a couple of videos on the website, and then spent about 1.5 hours on the job (honestly, at least 45 mins was me figuring out where I wanted to run the wire and strapping it in, then stopping to drink a beer and admire my work, with the actual hub work taking less than 20 mins apiece).

I was able to install the new whip, box, and run power to the hubs in about an hour afterwards. I then got in the truck, toggled to my trailer braking control, set my sensitivity, and went for a test drive. Works flawlessly!


Worked with Helen at etrailer to make sure the correct parts were ordered and supplied. Helen was a pleasure to work with and the hubs and bearings fit perfectly. A year later everything is still working great.
Thank you Helen and etrailer.


The brake parts were all correct for my application and installation was straightforward with minimal tools needed. I did take the extra step of soldering the wire connections because that is the best way to do it IMO.

Stephen at etrailer was very helpful. He made sure I had all the right parts for my application. and they were on their way very quickly.

I will say that I tried to use my local dealer first because I like to support local businesses, but unfortunately, they were having trouble finding the right parts for my trailer. When we did find them, they were 50% more expensive for the exact same parts that etrailer supplied. I would also have had to drive 80 miles round trip to get them.

The reason for the 4-star rating is because of shipping/packing. The parts were heavy in large boxes with no packing material to hold them in place. Two of the hub sets were out of their boxes and there was a crushed grease cap. So, better packing to keep things in place in the boxes or use a smaller box would be nice.

I attached a few pics of before and after also tmy very worn hubs. You can see that eh armature is worn down to the studs and the magnets are starting to show the coils. It was time. Also a short video or timelapse that I titled, Trailer Brakes in 18 seconds

I am sorry that the hubs arrived in this condition. Let me get you over to our customer service department for them to see what we can do for you.


Bought new Dexter brakes and drums to replace the original brakes on my 1995 Haulmark car trailer. The original drums and magnets were badly worn, and I wanted to replace them before going to the car cruise in Ocean City. I received an email from within hours of placing the order, stating that the order has shipped! The absolute best customer service I ever had. The parts arrived within days, and the packaging was superb. Thank you etrailer!

The Dexter parts are working great so far! Although I only used the trailer twice for about 450 miles total. Ive always had good service from etrailer. Thank you for the follow up, I appreciate it.


Installed perfectly and performed as expected.
was a switch out to a new trailer without brakes to adding Hubs & Drums with brakes. Everything worked out as planned and it was a quick change out.
Thanks for your help etrailer



Everything is still working as planned. The change out for the installation of trailer brakes is as planned. I specified these parts for the brakes but also so I could add a hand brake lever when the trailer is parked. I didnt want the possibility of it rolling. Additionally, this allowed me to drill a hole through the hand brake lever to lock it against theft. The entire parts and planning worked.


Customer service was excellent, fast shipping and perfect replacement parts.


Who doesn’t love a 20 minute hub change with bearings and grease?? I sure do and replaced all my hub bearing assemblies with these. It took about an hour and I was back on the road. I drove our TT about 150 miles over the weekend and it did great! Thanks to the staff at ETrailer for going above and beyond with the sale as well!


Got this with a 10 inch trailer brake. Everything was as expected. I had to buy a couple nylock nuts from Menards. They are 7/16 by 40 pitch. Which is a fine thread.



The brakes work great! Im really happy that I took the time to install them.


installed brakes on my 97 Rogue boat trailer. E-Trailer had everything I needed for the job. Trailer already had the 4-hole mounting plate for the backing plate. It was all bolt on, brakes work great. I have bought quite a few items from them over the past few years, including an axle assy with brakes for another boat trailer, 2 brake controllers and also a trailer hitch for our older Lexus suv. I am very satisfied with there service and quality of there merchandise.


The Dexter brakes and hubs are great - a bit pricey but far and above the no-name brands. There was one problem with the order (well 2 actually), they only shipped one brake in the package so there go my plans for installing the new hubs and brakes this weekend. This was an order for left-and-right brakes and two hubs. Mistakes happen so I'm not real upset about it. I'll update this review when I see how customer service handles this.

The second problem is the packaging. Nothing was damaged, which surprises me, but the two Drums and one brake were in their own boxes inside a bigger (huge) box with no peanuts or anything to keep them from flopping around. I lifted the box up on end so I could pick it up to carry it back to my work shed. When I did, it almost rolled out of my hands because the contents shifted so violently. When I got back there and opened the big box, the three smaller boxes were piled atop each other at one end.

FORTUNATLEY, they made it through the carrier's system, of which I am very familiar since I worked there for years. I was shocked they did. Better care when packing into larger boxes would go a long way.

Five stars for the products. Three (average) for the care in shipping the order.


Everything worked out well and are good replacements for existing drums. My only issue was the nuts and washers were too large for my spindle. Luckily my existing nut and washer were in good condition and could be reused.


I was impressed with these hubs (they cost a little more) heads and shoulders above some hubs I bought on Amazon and returned. Made in America was evident not only because its stamped on the drum but also by the quality. My recommendation if you have Dexter axles by Dexter drums


The brakes from etrailer were of excellent quality. They installed easily, and no adjustments were needed for the installation. After bleading the system, the brakes worked fine. I will definitely recommend etrailer to my friends and relatives needing trailer parts and accessories.


Really detailed helpful videos made installation a snap. I put brakes on a trailer that didn’t have them.

A word of caution. Unlike the brake kit, the drum kit only does one wheel. So if you order a brake kit and a drum kit you don’t have enough to do two wheels.


As a consumer in todays age, I look for service but also price adjusting when possible based on competition. Not the first time I ordered from Etrailer but I did find other competitors with lower pricing on the items I purchased. Comical to see that not appropriate for review is indicating anything contrary to excellent. Thus it is that pictures shown of damaged boxes may not reveal how the end product is used or affected but it is also part of the process of ordering in the future.

If asking for tips only or how to give rave reviews when the overall needs to be conveyed, then why offer it as an alternative to begin with?


Reassembly of parts went perfectly, I made the right choice with etrailer !!


Paula is the best very patient with me as I know nothing about hubs and brakes for a trailer. She walked me through everything I needed. She even called me back when I had more questions. Thanks Paula


Everything fit perfectly and there were no issues with the installation.
Working fine


We have been going camping out West snd Southwest for five years now. Pulling 2003 Jayco 12 Sd popup behind 2006 Chevrolet Express 2500. A lot of mountains. Big Mountains. I noticed that the hydraulic brakes on the camper didn't work properly. I have tried to adjust them multiple times but it didn't help. I decided to replace them with electric brakes . It looked like etrailer had exactly what I needed. I ordered the electric brakes assembly first and then hub and drum assembly. Had to take some measures for the brake plate mounting and also get part numbers of the old bearings in the hub. All parts arrived two days after order was placed. Amazing. All the parts were there. . I am not the greatest mechanic but I was able to install them fairly quickly. Installation videos on etrailer website and YouTube were very helpful. We just went on our first camping trip this year. Only two hours drive. It seems that everything works fine I can feel that new brakes actually work. Thanks to Nicole at etrailer for helping me with this order.


Appeared to be very professional and friendly but sent the wrong hubs. I specified that the original hubs has P/N Dexter 8-246 and was sent 8-247 (84546uc3-ez). 35k. I am sending them back to get the correct ones resent. (K08-426-91) 4,000k). This will be my second return. Thanks for working for me.


I just completed the install of the Timbren independent suspension system with dexter electric brakes and hubs on a 2008 TAB teardrop trailer. The was not an easy install on a 2008 TAB trailer. The original axel system bolted to a light frame and the spacing did not work with the new components. I had to build a 1/4 inch steel adapter plate shimmed out 1 inch to get the wheel clearance needed then bolt the Timbrens to the adapter plate. Now that it is all installed, the trailer runs much smoother since each wheel can step over bumps with out transferring the impact across a solid axel to the other side. The old system was an old style mechanical surge brake system which was worthless. The new electric brakes and a Tekonsha P3 controller works fine.


The trailer hub I ordered arrived early and was the correct part I needed. As a returning customer of 5 years, etrailer has earned my trust.



After a year of running my new hub and drum assembly from etrailer, Im still as satisfied as I was after replacing it a year ago. Still my go-to business for my trailer and truck needs.


Exact fit and high quality
Will definitely
purchase future items from etrailer!



Great product, after a brief brake in pun intended period where my controller needed Small adjustments, these rotor and brakes are synced to my truck perfectly. The easy lube hubs rock!

@Gary We're glad to hear that you're happy with your purchase!


I wanted to use original Dexter Axle Parts on my pop up camp trailer and that is what I received from The online process was extremely easy and when I discovered I made an error on my order I was able to quickly make the change and the parts were shipped very fast and at a good price. There are a lot of knock off parts out there claiming to be "Dexter quality" but not actual Dexter Axle Parts. Be aware! Trust when you want Original Dexter Axle Parts.



Buying high quality OEM parts provides a level of confidence that allows me to relax - NO WORRIES! The Dexter parts I received from went on easily, and now have performed like they were designed to and without problems. Dont cheap out get the best from the best at


I'm Out $[XX]+, etrailer sent wrong part. You can't return after 60 days :-(
I have a 2015 jayco jay flight Slx 145 RB. I called etrailer and ordered the brake and hub kits. The parts arrived promptly. I got covid so I didn't get to installing them right away. When I did, the hub wouldn't fit on the the axle. Now that the brakes are apart I can see that the original ones are 8-418 and etrailer sent me 8-247. My originals are 10" x 1-1/2" The ones they sent are 10"x2-1/4". Very disappointed with etrailer! You would think they could at least take them back with a restocking fee.
