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"

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




by:

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.




by:

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.

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.

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 etrailer.com 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!


Comments
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.
This
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




by:

I purchased a brake assembly and hub kit for my travel trailer. I had a 100% positive experience with etrailer. Very helpful in placing my order.
All parts were correct and fit perfectly.
The only minor problems I encountered were as follows. The printed instructions included with the hubs were copies, that had been recopied about 3000 times. Practically illegible. One of the brake assemblies arrived without the small plastic clip that secures the wires for the brake magnet to the backing plate. Both of these small problems were "in the box" from Dexter and not the fault of etrailer
I will have no hesitation dealing with etrailer in the future.

Great quality product, that’s why I get all my trailering equipment from etrailer.

Brakes still work like the day I put them on!

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.




by:

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.


Comments
The brakes work great! Im really happy that I took the time to install them.
Jonathan - 08/23/2016


by:

This trailer drum kit seems to work well as a direct replacement for the original equipment on my trailer. Reason for the 1 star deduction is that this kit does not include the axle washer with the notch that was on the original assembly and the packaging appears inadequate for small pack carrier shipping. (2 of 4 hub kits arrived with issues - one box was torn in transit resulting in missing pieces and a second arrived with a dented bearing race). Overall, a good quality product and if the manufacturer addresses the packaging issues to ensure everything arrives intact, it can be even better!

I will have our customer service team reach out to you. We do have the castle nut available separately if needed. If you have a one inch spindle it is part # 165686

The brake drum/hubs are excellent. The plastic bag with the bearings and other hardware didn’t survive shipping in 3 out of 4 instances. The included bearings are Chinese and would probably work fine, however I installed Timken bearings and races.




by:

Overall a direct replacement of my previous hub, only issue was that the new lug nuts provided in the kit were too large for the hub, had to use my old rusty ones instead.




by:

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.




by:

Everything arrived but I was surprised that small parts weren't lost because one cardboard box (brake drum) had split open and the inner bag (lug nuts, etc) was ripped.. I would encourage the packers to make sure packages are sturdy enough for the trip.




by:

Fit and finish was great as these are the same OEM brand That my trailer was build with

Easily installed bearings and hardware




by:

Fit was perfect and easy. One side arrived without hardware, folks at etrailer were quick to ship out 2 replacements.




by:

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?




by:

Parts were easy to order online, arrived quickly are OEM replacements pats.

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.




by:

Great drums, easy to install. Instructions were thorough. I'm taking away one star only because one of the bearing seals was slightly bent when it arrived. I was able to gently bend it back with a small wood block (used a small wood handled wire brush) and gentle hammer taps. Used Red RTV as directed to make sure the seal stayed tight over the years. The seal went in the same as the undamaged one and appears to have an effective fit. I think this was just a one-off issue since it only happened with 1 of the 4 I ordered. Overall easy installation of the kits. 2011 Dual Axel Wells Cargo utility trailer.




by:

Hub worked out fine for my 2012 Coachman Catalina travel trailer. Missed a 5-star rating because the cap was bent on receipt - was able to straighten out and use.




by:

Shipping was fast. Everything came without any issues and I was able to get my trailer repaired within 2 days of ordering parts.




by:

It took awhile to get the correct part numbers, but when done, the product installed nicely! Highly recommended.




by:

The brake kits (2) wheels, were great, It was so much easier to replace everything (drum, shoes, bearings seals etc). The self adjusting brakes work great too, had to play with it a little to get it wright, but that’s easy on a small trailer (Casita). Let me tell you, if you go to a RV shop and have them replace brake shoes and check all other components, you will pay way much more than just replacing everything with new yourself. Oh, the bearing races are preset in the drum, so you don’t have to remove and replace the baring races (that can save a lot of time and effort and special tools).

  • Difference Between Dexter Hub and Drum Assembly 84546UC3-EZ and 84546UC3
    The # 84546UC3 and # 84546UC3 -EZ Dexter Trailer Hub and Drum Assembly are identical with the exception of the grease cap. Each is a single hub with an integrated drum. They use the same bearings, races, and grease seals. The # 84546UC3-EZ has an EZ-Lube compatible grease cap designed to use with E-Z Lube trailer axles. The # 84546UC3 has the standard grease cap. I have attached a video review for both that you may reference.

  • Solution for Getting Trailer to Drop 2 inches to Fit Through Barn Garage Door
    The smallest wheels we offer that will fit over a 10 inch drum are 13 inches. I wish we had a smaller wheel that would fit. If it's just a garage door that you are trying to get past you could deflate the tires to the point where the trailer loses 2 inches in height, move the trailer past the door, and then reinflate the tires. Be sure to remember to do the same thing to get the trailer out!

  • Which Axle of Tandem Axle Trailer Usually has Brakes Installed on It
    The rule of thumb is that you want to put the brakes on the axle that is going to see more weight. For boat trailers where the motors (most of the weight) are at the rear of the trailer you will see the rear axle with the brakes. For utility trailers where most of the weight is in front of the axles the front axle is used. I attached a couple help artilces on adding brakes to trailer axles for you to check out as well.

  • Should Trailer Brakes be Put On the Front or Rear Axle of a Tandem Axle Trailer
    You would put the brakes on the forward axle of a tandem axle trailer and not the rear axle if you had to choose one axle. If you are referring to the video, that particular trailer did not have brake mounting flanges on the forward axle or it could be the one we worked on that only needed new parts on the rear axle. Either way traditionally you would put the brakes on the forward axle.

    The factory brake controllers such as the one in your 2015 Ram 3500 may need to be set up first before they will work as well as they can. On the 2015 Rams the factory controller also has an electric over hydraulic mode and if you are in that mode it may not work as well with regular electric brakes.

    Using too small of wire to carry the brake circuit can cause a number of problems ranging from poor brake performance to the wires melting. I would recommend you replace your current wiring with the recommended gauge wire. We typically recommend 10 gauge wire. You should note that locking up trailer wheels is not an effective way to slow down a trailer. You would want your trailer brakes to brake hard enough that they would almost lock up but never lock up. There are several other reasons...

  • Will Trailer Hub and Drum # 84546UC3-EZ Fit an ALKO 3500 Pound Axle
    I read through the other question you sent and I can clear some things up for you. First, the ALKO axle brake mounting flanges have a different bolt pattern than do Dexter or similar assemblies when you go up to a 12 inch brake assembly and that is why they will not fit ALKO axles. The top mounting holes on an ALKO mounting flange are wider than they are on a Dexter. But on a 10x2-1/4 inch brake assembly the 4 bolt pattern should be the same. So you can use other 10x2-1/4 inch assemblies...

Next thing I would do is try adjusting the brakes again, this time tighten them till you can't turn the assemblies by hand and then back it off 10 clicks.

If you are dead set on going this route I would recommend letting the trailer dry for several minutes before plugging the trailer connector back in. A better route that...
