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"

Initially ordered the wrong diameter hub assembly. Return was quick. Ordered the correct assembly. Greased the bearing, applied seal and installed Hub and drum assembly. Thanks to the FAQ on giving instructions how to order the correct bearings. Assembly is torqued and ready for the road.

Great product would never shop anywhere else. I never need to worry about this product failing. We went over the Rockies twice with our open car hauler.

I just took the whole assembly off to regrease and check for wear. Awesome results after a year of heavy and frequent use.

Tows like a dream. With the trailer attached is just like driving with no trailer at all. Brakes are responsive and smooth. Just on additional note: I replaced all 4 of the electric drum brakes with Dexter Electric Trailer Brake Kits. All bought from etrailer, all fit perfectly. No problems! Very happy with the product and the results.

I got these drums in to replace some old ones. the only thing I miss is the adjustment hole. But being an over cautious tower I inspect my trailer brakes often. Installed yesterday and they worked great. Ordered on a Sunday and received on Tuesday - but I live in the same shipping -zone I believe - got some great LED trailer lights as well. Image shows product installed.



by:

Great product and price . Next time I'll buy complete kit , brake shoes,magnets, drums etc.
I bought everything separately .all in one is cheaper . Brakes on my airstream are better than new!
Picture is old brakes and magnets I replaced at same time with new drums and bearings.

Good so far but havent been out much yet.



by:

Did a complete 4-wheel brake replacement on my 2010 Springdale 26', 5th-wheel. OEM Dexter drums and OEM Dexter Never-Adjust Electric Brake Kit. Spoke with etrailer rep and confirmed correct parts for my rig. Ordering was easy and delivered free in 4 days. Used the 4-days to remove old parts, clean under rig, maintenance to slide-out, etc. much easier with tires out of the way. Parts arrived and about 8 hours of work, it's all back together. Can't tell you if it works because we have not taken a trip yet. COVID19 puts a damper on traveling. But a good time to do deferred maintenance.

Perfect product for our fleet of traile rs

These hub drum assemblies came pre-rusted for me as you can see from the photos. Even with a desiccant pack in the box it didn’t help. If it were only on the braking surfaces I wouldn’t have an issue but it’s within the bearing portion of the hub also. The other issue is the thin small plastic bag that the bearings, seals, lug nuts and grease cap are supposed to be in is flimsy and tears open allowing the bearings to bounce around all over the inside of the box. A better bag would solve the problem. A quick call to Etrailer and new drums are on the way. They said they would verify no rust this time. I’m confident they will be fine this time as Etrailer has always been great to do business with in the past!



by:

Wow ! Great prices and fast shipping. Saved a ton.
I wish I had found you last year when I had to rebuild my othe Pace Shadow GT Trailer after some 150,000 towing miles. This open trailer has had a tougher life and maybe 50,000 miles.
We turned around while working on the trailer and there he was. The local turtle thinks he found a new girlfriend !!LOL Gues he likes your drums.

Perfect fit for my 6x12 dump trailer. Good price and fast shipping. Had 1 inner bearing damaged in box, appeared to be a shipping issue. etrailer replaced it immediately.

I have been using these replacement hubs and breaks for a year now. Other than routine inspection they have been perfect, quality parts.

These Dexter drum kits we’re awesome. It came with everything except a new cotter key. Maybe they will start adding a cotter key to the kit in the future.



by:

Let me mention that I have always had great service and no issues from etrailer until this Dexter order. The package arrived mostly damaged, I should have taken a photo but i opened it and everything looked ok mostly at first glance. The drums were loose inside a box that was too big. When I went to install the drums I first notice an issue with rust, if it wasnt inside the bearing area then i wouldnt have cared but i spent 20 mins cleaning the non preserved drums. then i went to install the seal and noticed it was damaged. I opened the other bag of hardware and same deal, both seals damaged. I then looked at the bearings and noticed an outer bearing was damaged. At this point im in need of drums and had to buy all new drums with seals and bearings from a local farm store, but i had to buy all new drums and hardware as a kit. So now i have these Dexter drums with damaged hardware. I could not wait for replacements etc.

Thanks to Dianna A. at E Trailer the Dexter brake kit recommended for my trailer axel was a perfect fit. The Dexter brake kit is top quality and every thing needed for easy replacement was in the kit.
E Trailer's video's and installation instructions helped guarantee the installation went smoothly

Couldn’t have got it any faster. Communication was great. Don’t think I will be shopping anywhere else going forward.

I Installed two sets on my 14 foot Trailer. In the mountains of NC, brakes dont seem to last on the truck. I use the truck and trailer for pick up and delivery of Ventracs, that weigh in at around 1500LBS. The trailer empty will actually stop the truck now. (I use the Redarc trailer brake controller).
Not having to constantly adjust them is a major plus also. I did wire both axles indepentanly of each other to the junction box. If I happen to have a wire get torn loose, I will only lose braking on one axle and not both.
They were a little expensive, but will save me from replacing the brakes on my truck twice a year.
Over all, I am glad I got the two sets.



by:

To anyone who is putting brakes on a trailer I got a set of electric brakes hubs bearing and seal and cap from e-trailer and everything
fit perfect. They even arrived 2 days earlier than I thought. I would recommend e-trailer over anyone else. They have the best quality
product for less and made in USA. For me if I need any trailer parts I wouldn't look any more. They have very friendly service and has someone there that not only works in office but understands and knows bearings and when you ask questions knows exactly what you are talking about. I am completely 100% satisfied with their product and service.

I was replacing a damaged OEM hub on my trailer's Dexter 3500lb. axle. This hub appeared in every way to be a direct replacement. It was great to have the included set of new bearings so I didn't have to worry about the condition of the old bearings. Bearings and hub install was straightforward and adjusting the bearing play was straightforward.

The hub and drum assembly I purchased is still working well a year later. No problems to report.



by:

Helpfully on time delivery one seal bacon arrival otherwise great service.



by:

Recieved the parts in a timely manner. They are large heavy items and do move around the shipping box, however no damage occured. Had to purchase the nuts & lock washers to attach the backing plate to the axle. Other than that everything was included.
I used a double10Ga. wire. Brakes went on like a dream......my wife greased the bearings so that is probably why. Immediately left Michigan for Florida with a farm tractor on the trailor, checked the hub temp at every stop and experanced no problems.
"Great Stuff" Sorry no pics.

Still doing the trick..



by:

I wasted a lot of time and effort with auto parts stores trying to find replacement studs for my 1991 7000 lb trailer. But once I figured out that Drexel Axel was the manufacturer and doesn't sell replacement studs, just a whole hub kit, I found etrailer.com and their generic replacement kit is significantly lower cost. It arrived in 2 days with std shipping and fits just fine. The installation instructions that came with the part made the installation easy.

Its working



by:

I had to replace the brake drums and brake shoes and magnets on my fifth wheel. It was cheaper to buy the completely assembled backing plates along with the drums then to replace the individual parts. Etrailer had the best price of all. They were very helpful when ordering and the parts arrived in two days. The parts fit perfect and the job was easy thanks to Etrailer.

    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.

  • How to Find New Hubs for Mobile Home Axle
    We won't have a kit, but there's a chance we might have parts to piece something together for you. I'll need to know the inner and outer wheel bearing reference number, the bolt pattern and size of your current wheels. Hopefully, we'll have a hub that is compatible with the wheel bearings you spindles use. Mobile home axles are designed for one-time use in moving a mobile home, and are meant to be discarded after that. Using mobile home axles and wheels seems like a great idea at the time...

  • Troubleshooting Stuck Bearing on Spindle
    Bearings can fit pretty tight on axle spindles. What you can do is apply some penetrating oil like WD40 to the portion of the bearing that is stuck on your spindle and then let it sit for a few minutes. Using a punch or a wedge you can carefully apply force on the outside of the bearings to get them off. You will want to work around the entire bearing so that the force is applied evenly. Be careful not to damage the spindle in the process.

  • Will Adding Trailer Brakes to One Axle of a Trailer Make the Wheels Stick Out Further
    Installing brakes on one axle will not make the wheels stick out any further than the idler axle.

I attached a help article that will walk you through the process of adding brakes to your trailer for you to check out.

    First thing to check is to make sure the brake assembly ground wire is connected properly. It's very possible the ground is bad and now the brakes just aren't applying.

  • Can 10 inch Brake Drums be Used with 13 inch Trailer Wheels
    There are exceptions to some rules, generally speaking 13 inch trailer wheels will not work with 10 inch hub and drums. Your wheels might be manufactured differently than most and there isn't a clearance issue like on most. I would imagine the clearance between the hub and the rim is pretty tight. I am glad your setup is working well and we appreciate your feedback.

    If you have electric brakes, disconnect the electrical connection from the tow vehicle. If they are hydraulic brakes make sure the trailer is not positioned so that it is pointed down a hill.

The pilot hole on your trailer wheel would need to be 2,6 inches (or larger if the wheel is centered on the hub using lug nuts).
