Trailer hub includes lug nuts, inner bearing (L68149) and race, outer bearing (L44649) and race, grease cap and grease seal. Fits 3,500-lb axles.
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.
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.)
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.)
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.

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

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. 209058

Excellent! As Expected. Most important, staff very helpful. I ordered parts and some did not fit but staff very helpful with return and then with identifying correct parts and then filling out the order. Next time when I'm uncertain of ordering correct part, I'll call and ask staff to help me identify the correct part before placing an order. 217587
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

These drums came with everything needed as well as both style grease caps, the standard and the greaseable ones, and went together as smooth as silk... adjusted up easy and worked perfect. going to buy another set for the other axle.... already recommended to others. 151007

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. 86236

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
Got these brake assembly's in and installed on my trailer they work great you can't beat the price and the quality. Etrailer is awesome 223978

made axle service a snap. 231031
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

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 etrailer.com 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

Added trailer brakes to factory Stratos boat trailer and these work great. Boat/trailer combo is 2006 model 275 Pro XL. I used the bearings that came with the assembly and both sides run cool. No complaints. Just FYI, the first set I purchased several years ago came with single lip seals. This most recent set purchased early 2016 came with double lip seals. Would be a good idea to check for sure if you are looking for double lip seals. For boat trailers, I would not use anything but a double lip. 328246

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. 292322

I use my boat (and subsequently the trailer) in the salt water here in the Pacific Northwest. As one knows, salt water takes a toll on exposed metal. These hubs have held up well and i don't see any signs of deterioration. I also installed stainless brakes with a fresh water flush system to ensure the inside gets a generous flush following each use. These parts are easy to install and I believe they will hold up to the harsh environment. 275598

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
by: George R.06/08/2016
Good product, happy they're made in America (Paid the extra $5 each because of that.). The included regular grease caps were not good, and started coming off. Had to use the others with the removable rubber plugs. One of those started walking off after about 300 miles. May have to swap some Bearing Buddies in place. Caps made in China, go figure... E Trailer is very good at getting products out the door and to you quickly. 258877
by: Steve S.06/16/2014
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
by: Dennis C.03/13/2012
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. They've always gotten my orders exactly right, their fulfillment/shipping timing is outstanding, and their online resources, such as instruction videos, are extremely helpful. 194044

Simply Exceptional Service! I wanted to make certain I ordered the correct parts to add brakes to a trailer and phoned their sales dept at 7:30 p.m. on a Wednesday evening. I then placed the order online after that. When I arrived home on Thursday the entire order was on my doorstep. And best of all the shipping was free. Great price, great customer service. 9675
by: Frank L.10/10/2014
I'm very satisfied with the drums I purchased. Looks like quality stuff. Love that the race is already pressed in. Everything fit on perfect. Also you can't beat the price. Drums, race, bearings, nuts, and cap all in/as one package. And I caught the free shipping! I must admit I haven't driven the trailer yet but foresee no problems. Thank You e Trailer. 155505
by: Archie A.09/29/2015
I was concerned about the condition of the 4 brake drums and related bearings when I opened the box and found everything piled up at the bottom. Fortunately everything was A-OK. The drums and bearings seem to be of good quality. Will install them on my trailer in a few days. Thank you for the fast delivery. 228436
it was what it said it was and shipping was fast like bunny.. and the price wasnt bad either. the info that this web site that helps you get the right part is the best part. it explained how to know which lugnut pattern and measure ments to go by.. all true story.. im am not a paid spokesmen... ? 313841
by: Rick B08/04/2012
This was the easiest brake job ever! from start to finish, from jacking up, taking off wheels and old hubs, installing backing plates, new bearings and hubs, and wiring took only 1 hour. They work perfectly! Super fast shipping and great customer service! Thank you! 50573
Great prices, fast & free shipping, exceeded my expectations 145263

A year ago I ordered 4 trailer brake assembly sets, brake drums and bearings. They arrived quickly and in good condition. Everything fit well and I had no problems when I towed my trailer across the country. I would definitely buy from Etrailer again. 343048

ZOOM!!! The order was accurately packed up, shipped across three states, and waiting for local delivery in less than 24 hours! The parts appear to be quality and direct bolt-in. My surge to electric brake conversion will soon be complete! 224660
by: Mike K.05/15/2015
I received the order in only 2 days! I had to repair wiring on 2 of the 4 brake assemblies, but it sounds like this is a Dexter parts problem. Easy repair of insulation on exposed wires right by the plastic grommets, and all is great! 193431
by: Randy Helms08/31/2016
The way you handle my order was very good I got it sooner than we talk about and everything was box up great and in good shape when I got it. I think you did a great job and I will use you again and tell all my friends about you. 289508

Product arrived sooner that expected and packaged extremely well. I liked seeing that "Built in the USA" stamped on the brake drum! Girls Michelle and Lexus very knowledgeable too! Thanks for good experience. 216435

We bought bearings,seals,brakes and brake drums for our horse trailer as we travel around with are furry pet.We give a A+ for quality,service and price .will use trailer for all are future needs. Thank you 304548
by: Chuck K.12/31/2015
Everything was great, except for the grease cap. The fit was a little tight and it was too thin to withstand the force of pressing it into place. I may need to use the old caps with are more substantial. 234607
Great customer service from etrailer. Hubs arrived very quickly. Hubs are excellent quality as you would expect from Dexter products. These hubs were an excellent replacement for my old 494 style hubs. 148300
by: Dave N.08/13/2014
I found it very easy to find the right product I needed. Received everything on time and packaged neatly. I would definitely recommend etrailer.com to everyone . I will definitely shop here again! 146503
The shipment arrived in one day. Installed the same afternoon with no problems. The only hardware not included was the locknuts for the backing plates. I'm overall pleased with the service. 104161
Hub fit like the original. The brakes did drag on the same location on the hub making me feel the hub was manufactured out of round. Does not come with the nut, washer or cotter pin. 72821

I purchase backing plates and drum for my trailer. The products fit and as advertised, very happy. Also the shipping was fast and a map showed the location during shipment. 205906

These have been amazing! I used this set to replace the odd lug spacing on my military m101 CDN trailer and it worked perfect. A lot easier too install than I expected too! 323834
