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"

Video Transcript for Dexter Trailer Hub and Drum Assembly Installation

Today we're gonna take a look at the Dexter Trailer Hub and Drum Assemblies.Now, there are several reasons why someone would want to change the hubs on their trailer. Either age, they're getting very old, the trailer's been sitting for a long time, moisture got inside, caused corrosion that way. Maybe the brake assembly itself locked up on you, it overheated that drum and we've got hot spots or cracking in it. Or you can have these machines where it can turn the drums, and you've just had it done so much that it's expanded too far, so where it's beyond the specification.Now, these drums are going work for 12-inch by two-inch brake assemblies. They're going be from the 52-hundred- up to the 7,000-pound axle, each one, and bearing kits rated for 35 hundred pounds. So a total of 7,000.Now, Dexter provides us with just about everything we're going to need.

We've got new lug nuts for our half-inch wheel studs. You got the new dust cap here and the easy-lube plug. Also, going to have two new bearings, inner and outer. And you're going to have your seal. So all in all, this is a way to completely replace all of these components, get it right back to factory fresh, and you'll have no problems with it heading down the road.Something else that I like, it's going to come with the eight lug nuts that we need, so we're not going to have to worry about our old ones if those we're cross threaded, if we had any kind of issues.

Everything's going to be fresh.Now, these offer heavy-duty iron construction. As you're putting them on, you can feel the weight and the density of them. And they're going to be designed to work with both the electric or hydraulic braking systems. And, as we can see right here, these are made right here in the United States.Now, to begin our replacement process, we're going to need to gather a few simple tools. Basically, we'll want a dead-blow hammer, a pair of channel locks, and needle-nose pliers.

These are really all we're going to need to get this replacement done.The first thing we need to do is get rid of our grease cap here on the end. Generally, we're going to tap outward. You can see that gap staring to increase. It'll pop off.Once that's out of the way, we've got a Cotter pin located right here. Get our Cotter pin out of there.Now, with our channel locks, we need to get ahold of this large nut here and get it removed.Now, as we take this apart, we want to salvage this washer right here.

This is our, kind of our thrust bearing there. And that's the only thing that doesn't come with our new drum assembly. We got new lug nuts, we've got a new cap, new bearings, new seals. This is that one component we want to be sure to hang on to when we put it back together.Now, we're just going to start working our hub assembly off. You see that old bearing. We're going to get rid of that.The brakes are kind of hanging up a little bit. We're going to be replacing those too, so I'm not too worried about them. So I'm just kind of using a pry bar just to get them worked off of here. And we'll slide it off.Now, as you can see, we've got all the grease off that spindle, got rid of all the old stuff. And this is our time to inspect it.We need to ensure, basically, that three main areas are in good shape. You got this ara here. This is going to be where the inner bearing rides. Nice and smooth, no issues there. Same thing out here, where our outer bearing goes.And then right in here on this wider area, you can see where it's real shiny there, that's where our seal is going to ride as it goes around. So we're just going to kind of rub our finger around there and make sure there's no nicks or dents or scratches or anything like that. What happens if we have that here is we fill this with grease, it's going to expand into our brakes, and that's not what we want.This one looks really good. If you have any discolored areas where it looks like it got hot, if you have any cracks that are running down through here, or if it looks like it's kind of been turned where the bearings have come apart and they're going to cause some issues, might be a candidate for replacement rather than just putting on hubs and drums.Now, the first step in getting our hub installed is going to be to pack our bearings. Now, you can do this by hand by just putting a big wad of grease in your hand there and then capturing it, forcing it in through here until it comes out of this upper portion. Or you can use a bearing packer, like what we've got here.Now, this we're going to put our cone down in the middle, and then we're going to force it down until grease comes through. You can see those red driplets all the way around here indicate we've got the grease all the way through.This is going to be our outer bearing. It's going to be closest to the outside. The larger bearing is going to be our inner bearing. Just get both of those full.Now, the larger inner bearing, we want to drop this in the back of our hub assembly. Now, we'll grab our seal and a dead-blow hammer. Now, if you don't have a dead-blow hammer, you can use a four-by-four block and a regular hammer. We just don't want to hit this with a metal hammer. It will probably deform it on us.We want to get that centered really well. We need to knock it down in. We want it to sit flush all the way around, just like that.Now, we're ready to grab our hub, and that's going to get slid right onto our spindle there. Just like that.Now, what I like to do is take our grease gun now, and we're going to pump that inside full. You can see these are not easy-lube spindles. These are standard spindles, but we wanted that double-lip grease seal back there. So now we'll just fill this interior cavity full.Now, we just going to slowly fill that up all the way around. It's going to get rid of any air pockets in there, make sure we don't have moisture that builds up, causes us corrosion issues.Now, I'll take our packed outer bearing. Let me get that slid up on there.We've got our washer. Remember we saved that from our removal process. And that's a new nut that comes with our axle kit.Now, we're going to use our channel locks. We're going to tighten this all the way up.Now, we're going to tighten this down. We're trying to compress everything, get everything seated properly. And we want to tighten that down to about 50 foot pounds.Once we get it there, without rotating our hub, we're going to loosen it back up and then just run it in finger tight.At that point, we've got our keeper. That's going to slide over. Just like that. And that'll keep that nut from backing off.Now, we've got our dust cap. We want to align that on the end of the hub, and with the dead-blow again, we're going . And we'll drive it in until it seats right down against the hub face. Like that.Then we've got our plug. That's going to go right on the end there. All right.And that's the same thing we're going to do for all four positions, depending on how many hubs you're changing.Now, to get these on properly, we want to tighten this in a star pattern. So we'll go from this on to the one opposite of it, come down to this one, and go to the one opposite of it. And you'll want to use a 21-millimeter socket. Once you get them down to the ground, torque them to specification.And that's going to complete our look at the Dexter Trailer Hub and Drum Assemblies.

Was great that the trailer hub and drum included new pressed in races with bearings, grease seal, nut and keeper. The convenience of having everything in one package saves you the hassle trying to look up and order these components separately. Likewise, the trailer brake assemblies. take old assy off, put new one on w 5 bolts. Glad the instructions included proper torque spec. Else - how would you know? Had to lightly sand slight bevel (1/64 ") at outer edge of each brake shoe. Drum fit quite tight or wouldn't fit at all w/o slight edge bevel to allow you to get it started. 717775

You just can’t beat etrailer’s support. They have full knowledge of the products they sell and are great to work with. I put together my wish list to upgrade my fifth wheel wheels and hubs, Steve went through the list piece by piece to ensure the proper fit and compatibility of each item. I felt much better after the call knowing I had all the correct parts. I also called back with a question during the installation phase, I worked with a very knowledgable technician, very helpful. Thanks to all in etrailer. 646685

I ordered this as spare hub assembly for my 5th Wheel RV. We are leaving next month on a 5000+ mile, 3 month trip. I figure if I have a bearing go bad I can swap out the whole hub and be back on the road in no time. The hub is the same Dexter hub that I have on my rig now. Shipping was fast and free, Helen was great, helping me find the part numbers of some of the other accessories that I needed to have spares of. Speaking of shipping I had checked other places for the hub and while the price was similar the freight charges were half the price of the hub. I will definitely be giving trailer my business going forward. 605388

I purchased these to upgrade my Fifth wheel from Six lug to 8 Lug. It is a quality Dexter part and fit my alko hayes T52 axel perfectly. I got these parts in two day! My only complaint is that the bearings and seals are packager in plastic bag. This allows them to band around during shipment. I had a pretty good dent in one of the bearing cages. It was cosmetic, but bearings are a precision part and should be treated better! 495476

Ask the Experts about this Dexter Axle Trailer Hubs and Drums

  • Dexter 7,000 lb Axle Hub and Brake Assembly Recommendation
    Does the spindle look damaged at all? Sometimes bearings can be a pretty tight fit to the spindle but there should be enough clearance to allow the bearing to slip on without needing too much effort. For Dexter 7k axles the bearing surfaces should measure 1.74 and 1.25. You'd want to make sure your spindle matches those diameters. Chances are the spindle may have gotten deformed from overheating and now it's not perfectly round.

  • How to Find Correct Replacement Hub for 7,000 lb Axle
    In order to find the correct replacement hubs for your 2016 Keystone Raptor, since you already know the weight rating of your axle, you need to know what bearings your current hub has. You will need to take apart your current hub assembly and look at the bearings themselves; wipe away the grease and you should be able to see the part number stamped directly on them. If you get back to me with that information I'd be happy to try and find the correct hub for you. If you are unable to...

  • Lug Nuts for 7K Dexter Axle
    We have many styles and sizes of trailer wheel lug nuts shown on the linked page. These are offered in either 60-degree or 90-degree coned profile, in zinc, chrome or stainless and for four different wheel stud diameters. Just click on the feature to see the products with that attribute. Most 7K hubs like Dexter # 42866UC3-EZ do use 1/2-inch wheel studs but we have lug nuts for 9/16-inch studs too, like # 6-53.

  • Can Dexter 7K Axle Electric Trailer Brake Assemblies be Used on 6K Axles
    You could use Dexter brakes # 23-464-465 for 7K axles but they will be a little more aggressive than ones specifically for 6K axles. What I recommend is etrailer brake set # AKEBRK-7-SA because they will work on Dexter axles, they are also self-adjusting, the cost less, and the shoe pad material is actually physically cut to the proper size rather than snapped off of a long sheet like other brakes (which leads to cracks and chips at the edges of the pad material).

  • Can 6,000 Pound Dexter Hubs be Replaced with Hubs that Have Different Bolt Pattern
    I reached out to my contact at Dexter and with the information you provided (thank you!) she was able to determine that you currently have the Dexter Trailer Hub and Drum Assemblies # 8-201-9UC3-EZ mounted to the 6,000 pound axles. This particular hub uses the # 25580 inner bearing and # 15123 outer bearing.

Both bearings are compatible with a different race or bearing cone. The races have a different outside diameter, so you wouldn't be able to simply swap out the race to change to the other bearing. Both bearings are also rated for a different weight capacity. The # 14125A bearing is rated for a 7000 lb axle, while the # LM67048 is rated for a 5200 or 6000...

  • Replacement Hub/Drum and Brake Assemblies Needed for a Hub/Drum Part # 92865
    From previous customer questions it sounds like the hub you have is similar to the Dexter Trailer Hub and Drum Assembly # 42866UC3-EZ. This is compatible with 5.2K - 7K trailer axles. They fit with 12" x 2" brake assemblies and have an 8 on 6-1/2" bolt pattern. You can verify that this is the correct replacement by measuring the locations on your spindle where your bearings and grease seal fits. If the measurements are 1.75" for the inner bearing, 1.25" for the outer bearing, and 2.25"...

  • Does Trailer Wheel Hub/Brake Drum Need to Be Replaced if Inside Surface is Grooved
    Because the face of the magnet rides against the armature (inside) surface of the brake drum, any grooves that had previously been worn into the armature surface will cause the magnet to wear unevenly. For optimal braking performance, you want maximum contact between the face of the magnet and the armature surface of the brake drum. If the drum itself got too hot, you might see some blue discoloration on the armature surface. In extreme cases, the armature surface can warp. It might...

  • How Tight Should the Spindle Nut be on a Trailer Hub
    When installing the castle nut on the end of the spindle, there is no specific torque rating but it sounds like your might be a little too loose. The nut is ran down until there is no side to side play in the hub, and then backed off to the next notch in the castle nut so the tang washer or cotter pin can secure the nut. Over-tightening the castle nut can damage the bearings, races and spindle. If you click on the video link I provided, and fast forward to the 4:45 minute mark, you...

  • Replacement Studs for a Trailer Hub and Drum Assembly # 42866UC3-EZ
    The replacement wheel stud you would need for your Trailer Hub & Drum Assembly # 42866UC3-EZ would be a Wheel Stud # 165995. Also, when you install the wheels onto your hubs you will want to torque them down to spec and then after 50-100 miles you will want to re-tighten them to the specified torque rating to prevent having the studs break in the future.

  • Rubbing Noise After Hub/Drum Install
    Thank you for the feedback, we sure do appreciate it! It's hard to say what the rubbing noise you are hearing is but I suspect the shoes on the backing plate are coming into contact with the drum which is completely normal but don't forget to adjust them prior to towing. I would then start with lubrication. In addition to packing each of the bearings before assembly you will also need to fill them with the right amount of grease.

  • How Tight Should Trailer Bearings Be When Installing on a Spindle
    Trailer bearings can fit pretty tight to the spindle, but they would not ever need to get pressed on. They should not be so tight that you have to really pound on them to fit but they can require a little bit of effort to get them to slide onto the spindle. When installed there should be no play between the inner surface of the bearing and the spindle. I have attached a link to a video that shows how to remove and reinstall trailer hub components you can check out.

  • Greasing Bearings and Hub for Dexter EZ Lube Hub and Drum for 5.2K to 7K Axles, 8 on 6-1/2
    If you have EZ lube axles then the hubs most likely use a double lip seal (which is what comes with hub # 42866UC3-EZ) that is going to be able to handle the use of a grease gun. But make sure to use a manual grease gun because the powered models do create much more pressure and can blow a grease seal. Make sure the grease used in the grease gun is the same as the grease used to pack the bearings or, if different, make sure they two greases are compatible. I have included a link to a...

  • Replacement Axles for a 2010 Jayco Designer 5th Wheel Trailer
    I do have an option for you but we do not have a standard axle that would work on your 2010 Jayco Designer 5th wheel trailer. Instead, you would want to look into one of our Timbren Axle-Less Trailer Suspension Systems like part # TASR7KS01. This system will actually replace the leaf springs on your trailer with a set of aeon springs that will work to absorb road shock and support the trailer's load better than the traditional leaf springs would. In order to add brakes you can use the...

  • Will Dexter E-Z Lube Trailer Hub Assembly Work on Non E-Z Lube Spindle
    As long as the spindles on your trailer use the # 25580 inner bearing and the # 14125A outer bearing, the Dexter Trailer Hub and Drum Assembly # 42866UC3-EZ will work perfectly whether or not you have E-Z Lube spindles. The only difference between this EZ Lube hub and a non E-Z Lube hub is that this hub will have a removable rubber seal on the cap that allows easy access to a grease fitting that would be on E-Z Lube Spindles. You can absolutely use this on your standard spindles, though....

  • Replacement Hubs and Brake Assemblies for 7k Liberty Axles
    There's a chance we have what you need. If you measure the inner diameter of the bearing marked 14183A and it turns out to be 1.25 inches the hub # 42866UC3-EZ would fit it. Then for brake assemblies the part # 23-464-465 would be what you'd need.

  • How to Determine Correct Hub Replacement For Hubs With 25580 and 14125A Bearings
    Thanks for that information, and I can tell you that the 1.750 bearing is # 25580 and the 1.250 bearing is most likely # 14125A. While that is most of the information needed, you also need to know your axle capacity as well as the grease seal, or it's inner diameter. If you don't have this you can measure the spindle where the seal rides to find out. The most likely hubs for you are the Dexter Trailer Hub and Drum Assembly - 5,200-lb to 7,000-lb E-Z Lube Axles # 42866UC3-EZ or the...

  • How to Select the Correct Hub and Drum for Trailer
    I am attaching a picture that you can use to see where you will need to measure your spindle.

Once you know the size of your spindle you can then pick our a hub and drum assembly that uses the correct bearing and seal sizes that you will need.

  • Bearings for 7,000 lb Dexter Axle and is Press Needed to Install
    For a 7,000 lb axle with a hub such as Dexter Trailer Hub and Drum Assembly # 42866UC3-EZ you need Inner Bearing # 25580, Inner Race # 25520, Outer Bearing # 14125A and Outer Race # 14276. You will also need Grease Seal # GS-2125DL (2.125" inner diameter) or # GS-2250DL (2.250" inner diameter) though the only way to know this for certain is to check the part number on the seal itself or use Digital Calipers # 301-17068 to measure your spindle where the seal rides. A press isn't necessary...

  • How to Pick Out New Hubs for a Construction Trailer
    In order to pick out the correct hub assembly for a trailer we are going to need know a few key pieces of information. The first thing you will need to know is the bolt pattern of your hubs. This is so you get a hub that is compatible with your wheels. I attached an FAQ article on determining bolt pattern for you to check out. If you are looking for a different bolt pattern this step can be skipped for now. Next thing we will need to know is what spindle you have on your trailer. In...

  • Should Grease Be Added to EZ Lube Trailer Hubs if the Bearings were Manually Packed with Grease
    On EZ lube hubs and axles you would want to add grease until it is full (when you see it flow out). When that happens it indicates that the proper amount of grease is in the hub. Having the bearings packed and the little bit of grease you have added is probably fine but it is better to be safe and fill 'em up!

  • Spare Hub Recommendation for 2016 Keystone Outback with 5,200 lb Axles
    Since you have the EZ lube spindles the correct hub you'd need is the part # 42866UC3-EZ. The agricultural 42 spindle has the same dimensions as the non-agricultural spindle so either way this is the correct fit.
