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"

Video Transcript for Dexter Trailer Hubs and Drums 84546UC3 Review

Today were going to review part number 84546UC3. This is the Dexter Trailer Hub and Drum Assembly for 3,500 pound axles with the 5 on 4 inch bolt pattern. This trailer hub and drum assembly will fit most 3,500 pound axles including the Dexter. The dimensions on it is 10 inches in diameter, 2 inches wide. The bolt pattern is the 5 lugs on 4 inch bolt pattern. This hub and drum assembly does come with the lug nuts, does come with the inner bearing which is part number L68149, comes with the outer bearing which is part number L44649, comes with the greased seal, part number 58846, and it also comes with the grease cap.

Now the races are included and they are already installed. You can see the outer race which is in there. If I turn it over you can see right in here the inner race. Those will come all pre-installed so the bearings will slide right in. Basically, as youll see the outer bearing will fit right in there, and the inner bearing will fit right into that race.

The seal will actually have to be installed right in there after the bearing is put in, and then the grease cap is what will go over the outer bearing. And as you can see the lug nuts, you can screw right on to the wheel studs. Again, the weight capacity on this one hub and drum assembly is 1,750 pounds so when you use this with the other one, two of them on an axle, it will have a capacity for the 3,500 pound axle. And, just to show you that measurement we had talked about. The diameter is measured inside to inside for your brake assembly so it would use a 10 inch diameter brake assembly; and then the width for the brake shoe would be measured from here to here.

So, if we put that on it would be 2 . So it will use a brake assembly that is 10 inch diameter by 2 wide. And that should do it for the review on part number 84546UC3. This is the Dexter Trailer Hub and Drum Assembly for a 3,500 pound axle.

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. Jeff Cannedy 78324

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.

With only 10days left before a 1,000mi trip with the family travel trailer, I decided to check one of the brakes for wear. To my great dismay the brakes were heavily worn. On last Friday afternoon, etrailer customer service helped me determine what parts would be needed for my application and for a little over $400, I ordered everything to make completely new again. I received completely assembled electric brakes, new wheel bearings and drums for four wheels. The items were rec'd on the following Wednesday with standard shipping. Wednesday evening I installed all new parts, which all were correct and now I am ready to roll with 6 days to spare. I would strongly recommend etrailer for your trailer needs. 52675

I ordered a complete brake kit for my 6x10 wells cargo trailer (backing plates wiring, hub assemblies, junction box). The items were not packed well and the brake wire got shredded by the hub assemblies during shipping. A quick call to eTrailer and a replacement cable was sent out right away - great customer service! Installation of this kit was a breeze thanks to the instructional videos available on the eTrailer website. All the items are of excellent quality and everything fit together perfectly. One small wish would be to include the lock washers and nuts (4 per side) that are required to mount the backing plate instead of having to order it a la carte. 189625

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. 27884

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 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. 209058

I had one drum worn on my travel trailer to beyond resurfacing due to a faulty magnet/armature operation. I went to etrailer and viewed the video on this particular model for the 3500 lb axle. The video was easy to understand which helped my confidence in doing this job. etrailer had the exact drum assembly which came with the races already pressed into the drum. The bearings and seals came separately. One stop shopping is great. I have been a customer of etrailer for many years and always was pleased with their customer service. 206835

I was pleasantly surprised when I received notice that my order from had arrived at my shipping address. Then when I came to pick it up I was delighted again to see how well it had been prepared for shipping to protect against damage in transit. I have not yet opened the packages as other business has been in the way but a peek inside made me think all is well there too. I will report further as I have time. Thanks for the speed at which you delivered the goods. I look foreward to a long association with your company. 178724

The web site it excellent and informative!!! I ordered a complete electric brake system for a new single axle trailer including controller for the truck, which all came in a timely manner and in good condition. BUT, they should have supplied the BASTARD NUTS (7/16"-20) for the two backing plates. I lost a few hours trying to locate the nuts. Also, the bearing caps are so thin that they dent with the slightest hit with a rubber hammer. 111407

Purchased 5 lug 4.5 hub and electric break assembly with controller and wiring. The Web site was easy to follow. Video demonstrations gave me enough information to place an order with confidence I was getting the correct parts. They will be installed on a 24 ft open car trailot. Shipping was fast. I would recommend your company to others. I will write a second review when I install parts and take it for a pull to the drag strip this spring. 6895

I ordered a new hub for my trailer. I was pleasantly surprised to find new lug nuts and an additional dust cap in the packaging. The whole exchange from old hub with new bearings and races plus the inner seal took about 20 minutes. I noticed the bearings were made in China (as were the original bearings!)...had the whole package been made in the USA, I would have rated my experience as excellent....still I am very satisfied. 187754

Good hub/drum assembly. Had a problem after I got them on with my wheel not wanting to fit. Still haven't figured out how a wheel that was on a 5-on-4.5 hub wouldn't fit this hub. The old wheels appeared to be off a car, maybe that was the problem. Just got some new wheels meant for trailers and they fit perfectly. The only other issue I ran into was getting the dust caps on turned out to be a painful process for some reason. 88705

What a deal, Drum, Bearings, Seal and new lug nuts. I can't say enough how I think e-trailer has the best prices out there. Drums were packaged nicely, bearings and caps, seals, nuts etc.. were packaged separately in a separate box the same box the drums came in. Drums made in America, bearings made in China, whatever, all brand new and all fit perfectly, thanks everyone at e-trailer :) 135807

I have not yet installed the new hubs/brakes on my trailer. I did open the box and inspect what was shipped. Everything ordered was there and appear to be of good quality. Shipping was fast and I found etrailer prices to be lower than most other internet dealers. Plus other dealers charge for basic shipping ($30+), making this a very cost effective way to add brakes to my trailer. 33768

I've only had my new brakes out for a short test drive, and they seem to work just fine. They arrived packaged well, no damage, and I received everything as ordered. Etrailer as an online retailer is excellent.

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. 217679

  • 10 by 2-1/4 Inch Brakes Needed for a 20 foot Boat Trailer with Brake Mounting Flanges
  • The # 23-468 and # 23-469 brake assemblies will work on an axle with a 4 bolt mounting flange that has bolt holes 2-7/8 inches on center apart. The Trailer Hub & Drum Assembly, # 84546UC3, is designed to work on trailers with spindles that accept the # L68149 inner and # L44649 outer bearing, and the # 58846 single lip seal, and with wheels that have a 5 on 4-1/2 inch bolt pattern. You should check these items to be sure you are selecting the correct parts. If your parts are different,...

  • Trailer Hub and Drum Is Stuck On Trailer and Brakes Will Not Release
  • 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. If it is and it is connected to the tow vehicle, the weight of the trailer can push in actuator and apply pressure to the brakes. Once you have the hubs removed you are going to want to inspect the inside surfaces where the pads touch and where the magnet (if electric) attaches (the armature surface)....

  • Replacement Brake Shoes for 10 x 1-3/4-inch Brakes on 22-Foot Travel Trailer with 3500-lb Axles
  • We offer replacement brake shoes for 10 x 1-1/2- and 10 x 2-1/4-inch electric drum brakes but no longer for the 1-3/4-inch width you reference. Dexter part # bp04-065 you referenced is a set of replacement brake shoes for electric trailer brakes normally seen on Dexter 2.8K axles. I was not able to find any brake part with the reference number 1530114. It does sound like an update is in order. If you want to replace your brake assemblies and hubs/drum assemblies you will need to match...

  • Recommended Hub Stud Bolts for a Hub Using L64819 and L44649 Bearings
  • If your hub uses the # L68149 and # L44649 bearings included in the # BK2-100 kit, it is most likely very similar to the # 84546UC3 hub drum assembly we offer, which has a 5 on 4-1/2 bolt pattern and works with 3500 pound axles. The # 84546UC3 hub drum would accept 1/2 inch drive-in stud kit # RG03-040, which is 1-13/16 inches long. If you find that your current studs do not match the # RG03-040 kit, I recommend looking at the rest of the drive-in studs we offer, as they come...

  • What Hubs Will Fit Redline 2-Inch x 4-Inch Round Spindle # R40484
  • The spindle you reference, Redline # R40484, is rated for use on 3500-lb axles. This spindle is compatible with both of the hubs you mentioned, parts # 84545BX, which is an idler hub; and # 84546UC3-EZ, which is a 10-inch drum brake hub intended for use with EZ-Lube spindles. The Redline spindle is not an EZ-Lube spindle but it would still work with hub # 84546UC3-EZ. If you prefer a non-EZ-Lube version of this hub you can use part # 84546UC3.

  • Trailer Brakes Lock Up When Hooked to Breakaway Battery
  • It sounds like you found out why the brakes were activated while you were towing the trailer to storage, so that solves that problem. Now we will want to figure out why the brakes are still locking up with the new breakaway switch. Even if you fried the brake magnets, the brakes should not lock up if the breakaway system is setup properly. I recommend inspecting the wiring of the breakaway system on your trailer to see why power is reaching the brake assemblies. I have attached a wiring...

  • What is the Smallest Wheel that will Fit Over a 10 inch Brake Assembly
  • The smallest rim that will fit over a 10 inch brake assembly is a 14 inch wheel. The smallest wheel and tire combo that is 14 inches in diameter and has the 5 on 4-1/2 inch bolt pattern would be the Karrier ST205/75R14 Radial Trailer Tire with 14 inch White Wheel # AM32153. This tire has a capacity of 1,760 lbs at 50 psi and has a speed rating of 65 mph. I attached a couple FAQ articles that you might find informative as well.

  • How to Add Trailer Brakes to a Home Made Trailer
  • If your trailer axle has spindles with mounting flanges, # R20384EZ, on them then the conversion to electric trailer brakes should be fairly easy. You will need electric brake assemblies, # 23-26, sized properly for the trailers gross weight loaded and ready to travel. You will also need trailer hub and drum assemblies, # 84546UC3, sized properly to match the trailer spindles, wheel bolt pattern and the brake assembly selected. If your spindles do not have mounting flanges you will need...

  • Replacement Hub for Hammer Blow Hub Part HB732 on Old Trailer
  • My online research did not turn up any direct replacement parts for the HB732 hub you referenced. However, we can help you select new replacement hubs. The things you need to know in order to select replacement hubs are: the bolt pattern on your current hubs (and wheels); the bearing numbers from your inner and outer bearings; the grease seal number; and the axle's weight rating. For example, Dexter Hub # 84546UC3 has a 5 on 4-1/2 bolt pattern, works with inner bearing # L68149 and outer...

  • Replacement 10 Inch 5-on-5 Bolt Pattern Brake Drums for Old Car Trailer
  • I did a Google search on the information you found on your brake drums and wasn't able to find anything conclusive regarding a replacement. We offer one 10 x 2-1/4 inch brake drum with a 5 on 5 bolt pattern, part # 84556UC3 for a standard or # 84556UC3-EZ for an EZ-Lube spindle. If your existing hub uses an #L68149 inner and an # L44649 outer wheel bearing, either of these hubs would be compatible. The hubs include the bearings, races, seal, grease cap, wheel bolts and lug nuts. If...

  • How Do I Determine Which Electric Brakes will Fit my 3500 Pound Axle
  • If you do not have drums already but have standard idler hubs, we would first need to select a drum, then make sure the brake assembly will fit inside that drum. As you guessed, the way to do that is pull apart the hub and bearing numbers. For example, we can say you pull the hub apart and find you have the L68149 inner and L44649 outer bearing configuration, and your wheels are 5 on 4-1/2 lug pattern. With that information we know that you need the Dexter drum assembly, part # 84546UC3....

  • Axle and Brake Compatibilty for a UTV Trailer
  • Dexter is one of the largest suppliers of OEM trailer axles, suspensions, and hubs. Their parts, including brakes, are available across the country. Since we do not carry the Rockwell American brand, I am unfamiliar with their products and can not speak for their availability. When it comes to adding brakes to a Dexter axle, you would just need the left and right brake assemblies and the hub/drum assemblies. For the brakes, I recommend the Nev-R-Adjust Electric Brake Assembly, left...

  • Replacement Hub for Single-Axle Trailer with 5-on-4-1/2 Bolt Pattern Using L44649/L68149 Bearings
  • Since your trailer is used and you may not know the level of routine maintenance it received from the previous owner I do suggest you replace your hubs, bearings, races and seals to ensure that everything is new and in good working order. This will prevent the awful possibility of having to pull things apart in the near future because one item has suddenly decided to fail. If everything is new you know you have a good service life ahead of you. If you do want to replace just your inner...

  • Hub And Drum Recommendation For 3500 Lb Axle On Enclosed Trailer
  • The Trailer Hub & Drum Assembly # 84546UC3-EZ, is designed to work with EZ Lube spindles, but will work on a non EZ Lube system as well. The cap that is included with this assembly has a rubber plug that when removed will give you access to the zerk fitting on the EZ lube spindles. This hub assembly has a 5 on 4-1/2 bolt pattern and is designed for 3,500 lb axles, and fits bearings # L68149 and # L44649.

  • How to Add Brakes to a Shorelander Boat Trailer
  • You gave me a lot of info on your trailer, but what I really need first is the dimensions of the spindle on your trailer so that we can determine what hub/drums you would need. You also will need to know if you have brake mounting flanges on your current spindles as well. I attached a help article that will walk you through the entire process of adding brakes to your trailer as well. I wasn't sure if you planned to add disc or drum brakes so I attached articles for both. In order to...

  • Does the Dexter Trailer Hub and Drum Assembly # 84546UC3 Come Fully Assembled
  • The Dexter Trailer Hub and Drum Assembly, part # 84546UC3, is a trailer hub and drum with the lug nuts, bearings, bearing races, grease cap and grease seal included. It is designed to fit 3,500-lb axles. After removing your old drum and cleaning the spindle you will need to install the hub and drum with the included parts to your spindle. The hub will have the bearing races installed but the inner bearing will need to be greased and installed in the hub and drum along with the grease...

  • 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.

  • Which Hub Drums and Brake Assemblies for 3500lb Axle on Utility Trailer
  • It sounds like you have a pretty good handle on what you need. If your existing hubs use the 5 lug on 4-1/2 inch bolt circle, and the surface of your spindle where the grease seal rides is around 1.719 inches, the # 84546UC3 is the proper hub/drum. You can go with standard brake assemblies, like # 23-26 for the left side and # 23-27 for the right. However, I'd recommend going with Nev-R-Adjust assemblies like part # 23-469 or the right sided and # 23-468 for the right. As the brake...

  • What Size Wheel Center Pilot Hole Will Fit the Trailer Hub and Drum Assembly # 84546UC3
  • I went out to the warehouse to measure the outside diameter of the center of the hub # 84546UC3. I used a set of digital dial calipers to take the measurement and came up with 2.6 inches in diameter at the widest point. 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).
