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

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
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

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
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

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

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

I purchased some product on Monday and had it on Wednesday. I had also called with some questions while completing my pepair project and they were VERY HELPFUL with my questions. I would HIGHLY RECOMMEND ETRAILER.COM!!!!! 27215
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
Complete kit exact replacement This drum replaced the worn out one on my '95 Jayco perfectly. Came with everything I needed. One note, the bearings are not pre-packed. 2963

My 17 year old hubs were badly damaged from contact with the worn electromagnets. This kit made it very easy to swap out the hubs with all new components. 37424
