Thoroughly Tested for Safety

This hub-and-drum assembly meets the requirements for certification by the Canadian Standards Association (CSA). The CSA creates standards, which when complied with ensure a safe and quality product. This assembly underwent extensive testing to measure stopping distances when braking. This assembly has also been tested by QAI for braking performance in a complete automotive setup and under real-world conditions to provide the most realistic scenario for the everyday driver.

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 etrailer Trailer Hub and Drum Assembly Review

Speaker 1: Today we're gonna be taking a look at etrailer line of trailer hub and drum assemblies. These are designed to work with 3,500 lb axles and offer a 10" diameter. They're available in the 5 on 4-1/2" bolt pattern with and without the easy lube hubs, the 5 on 4-3/4" bolt pattern with and without easy lube hubs, and the 5 on 5" bolt pattern.This hub and drum kit is designed to work with electric brakes. It's gonna give us the outer surface just like the brakes on a car. The shoes expand outward grabbing ahold of the drum, slowing it down through friction. To do that, it's gonna use a magnet.

You can see this machined surface that we've got here. It just floats along that surface until it's energized. When it's energized, it sticks, and that moves our lever arm on our brakes, expanding them out. You can see the quality in construction here.When deciding on the right hub, there's no huge differences in them. Basically, the only way you're really gonna be able to tell a good hub, like what we've got here, from a poor quality hub is just in the way it looks.

Their holes like we talked about aren't gonna be clean. The machined surfaces aren't gonna be as nice, and there's likely gonna be overcast on these outside edges. You can see they just didn't take the time to really get it perfect.Regardless of which bolt pattern choose, you're gonna have everything you need in the hub kit to get it put together. You can see we're gonna have brand new lug nuts. We won't have to worry if we've got some that are worn out or stripped.

No issues there. We've got new bearings we'll be able to put in. We're also gonna have a new seal. Once we get our inner bearing put in place, we're gonna have our new seal to go right down in there, keep everything in. That seals right around the spindle, keeps our grease from coming out of the back side there.There is a messy part of the job involved, and that's packing the bearings.

We recommend, if you're going to be doing a marine application, using a marine grade grease, or for non-marine applications, just a high temp. This is an LMX red. It's available on our website. There's several strategies to packing bearings. There are bearing packers available, which we do have on our website as well. I prefer just an old fashioned style. I'm just gonna take some grease, spread it around on my hand there. You'll see the bearing tapers. I like to go on the larger side here, and I'm gonna use that gap to scoop up grease. There it goes in there. Right in that gap. But if we continue to do that, the slight pressure we create on our hand will force that grease up between each of these rollers. I'm getting some to start to come out of there, so you can see it. You see right here on the top Got those little grease droplets poking through, that's where we'll know our bearing has been packed. Then we'll just turn it a little bit, continue doing that. We wanna see those start to come up all the way around the bearing. That means we've got our bearing full packed full of grease. Inner bearing's gonna be the same way. Just gonna take a little less grease because it's a little bit smaller.We'll place our outer bearing right inside the back of the hub. We'll make sure it seats in there properly. We've got our seal that's included with the kit. That's designed to fit down inside. It's kind of a pressure fit, so you will have to knock it in. We recommend using part number PTW83020. It's a seal, race, bearing driver. It's gonna help to give you a nice contact point on the back of that seal as you drive it in place. If you don't have one of these handy or if you didn't order one, you can use a 4x4 block. That's pretty common, too. Just place it on there and gently tap it down into place. The key to it is just to get it started squarely initially. You can see we're in all the way around there. Now we'll just drive it down so it's flush. You'll hear it come to a stopping point. You can see that's gonna go just inside that lip a little bit. That'll be perfect for us. We'll have to wait to put on the outside until we get it on our spindle.Something I like to do is take grease and pack it in the hub while we still have it off of the trailer. If you're using the easy lube style, then you're not gonna have to worry about doing this. You can fill it up with the grease gun after you have it on the trailer, but for the non-easy lube style, we wanna get this full so we don't have any room for moisture to get in there, which is what caused the rust on those spindles to start with. Nice and full of grease all the way around. We'll get it slid onto our spindle.Let's just get that slid on. You wanna try to keep it centered over the spindle so we don't have too much grease that we push out this way. Now, we'll place our outer bearing in. We want the taper to face in towards the hub. Get that seated in there. Then we need to replace the bearing that we removed. Then we can replace the washer. Some people call it a bushing. Put our nut back on. We'll run that down. You'll feel it begin to get tight. You see there's a little bit of resistance in our hub there. I like to just make sure that we get it fully compressed. Then what we'll do is back that off just a little bit. Wanna make sure that our hub spins pretty freely, but also you should be able to pull out and in on it and not feel any movement. We don't want any what they call end play. We don't want this to move in and out at all. Then we wanna take our cotter pin, slide that back through, and then just bend those back over. Just like that.We've got our dust cap that we can put in place. Depending on your axle, these may be a little bit different. For the standard style, you're just gonna have a solid dust cap. For these easy lube style, you have a little bit different cap that's gonna have a plug in it so you can access the grease cert. It's gonna be just like our seal. We wanna get it on. We wanna get it squarely in position, and then just tap it in a little bit at a time. We'll tap all the way around that edge until it seats all the way in and against our hub. Sometimes this cap is gonna deform. It's just part of it to get it seated in there properly.Just to make sure that our new brake assembly's gonna work out properly with our hub assembly, you can hook your vehicle up to your truck, whatever you're gonna be pulling with or if you have a trailer tester you can use that. You just want to move it. You can see we've got free movement now. Go ahead and turn the brakes on. And you see that's gonna lock up, stop our brakes from moving. That means we've got a good working system. This is gonna work well together. As we start applying our brakes during use, it's gonna automatically adjust to the proper tension for us.Now, you wanna head over to the other side of the trailer and get your hub installed there in the exact same way. Once we have both of our hubs installed, we can put our tire back on, and we'll secure that in place with the new provided lug nuts. When installing your lug nuts, you want the tapered side to face towards your wheel. Then we'll snug them up and torque them down.With everything working properly, that's gonna complete our installation of the etrailer self-adjusting 10" electric trailer brake kit.

I got this pair of brakes to install on my 16' equipment trailer yesterday and installed both on rear axle today in about 2 hours and everything works as it should. Note; every part fit perfect, my one suggestion to improve this kit would be if you added the 8 7/16" nuts and lock washers but you have a winner. 529765

I ordered drums to replace the old 4 lug 9.44 inch spacing the old drums had. It was a perfect match. My only problem was the old fiberglass travel trailer I was restoring had a wheel well that would only except a 25 inch tall tire at the most. The drums I installed were five lug with 5 in spacing. Only one rim would fit and that was a 15 inch. So naturally I freaked out! I called etrailer and spoke with Ashley. Ashley was very helpful and knowledgeable. I called some of my friends about my possibilities. I was able to find tires that were shorter then 205's etrailer is extremely helpful! 607952

Great pro-active customer support. A pleasure working with a company that knows how to actually do online business. The best I have found. I had a couple of questions before the purchase and your tech support was spot on, asking the correct questions, giving the correct information. Now to the actual product - the drums fit perfect (thanks to the questions and answers from your tech support). The bearings fit the shaft perfectly. I put your companies brake assembly onto a shaft that didn't originally have brakes. All of it lines up great. I was a bit surprised that there wasn't a keeper, a shaft nut, or the nuts for the brake bolts. But that is a small item to pick up at the local hardware store. Thanks again! 596292

  • Wheel Recommendation for Timbren Axle-Less Trailer Suspension System # A12WS545
  • After doing some research on the 2011 Jeep Wrangler, it appears the bolt pattern of the OEM wheels is 5 on 5 inches. If that is the case, they will not be compatible with the hubs that come with the Timbren Axle-Less Trailer Suspension System, # A12WS545, that you referenced in your question. The hubs and spindles included are designed for 5 on 4-1/2 bolt patterns. If you are unsure of your wheel's bolt pattern, I have included a helpful article that explains how to measure this. I do...

  • Replacement Drum Assemblies for AL-KO 8490 Hubs
  • According to my research, AL-KO 8490 references an AL-KO hub for 3,500 lb axles with a 10 x 2-1/4" drum and a 5 on 4-1/2" bolt pattern. For a drum assembly that will work with these hubs I recommend taking a look at the Electric Trailer Brake Kit part # AKEBRK-35-SA for self-adjust or part # AKEBRK-35 for manual adjust. If you would also like to replace the hub then as long as your existing AL-KO hub uses an L68149 inner bearing and an L44649 outer bearing, the Trailer Hub and Drum Assembly...

You need to take apart your old hub in order to find out if you have the same bearing numbers. If so hub and drum assembly # AKHD-550-35-K will work; for an idler hub assembly # AKIHUB-550-35-K would be the right choice. I've added a link to video reviews of these parts for you...

For traditional 5 on 4-1/2 inch bolt pattern, Trailer Hub and Drum Assembly - 3,500-lb Axles - 10" Diameter, I recommend # AKHD-545-35-K. For 5 on 5 inches, I recommend # AKHD-550-35-K. For 5 on 5-1/2 inches, I recommend the # AKHD-555-35-K. For 6 on 5-1/2 inches, I recommend the # AKHD-655-35-K. If you have...

You'll want to verify this is correct with your current bearings. If this is the case for a hub and drum assembly I recommend # AKHD-550-35-EZ-K which is for E-Z Lube axles with a zerk fitting. If you have standard axles use # AKHD-550-35-K instead. If you only need idler hubs use # AKIHUB-550-35-EZ-K with E-Z Lube axles and...

These assemblies will self-adjust to ensure you have the best braking without needing to manually adjust them every few months. Then for your 5 on 5 inch hubs, I recommend the Trailer Hub and Drum Assembly - 3,500-lb Axles - 10" Diameter - 5 on 5 # AKHD-550-35-K.

  • Adding Brakes to One Axle on a 16 Foot Parker Trailer
  • The general rule when adding brakes to a tandem axle trailer is that if the trailer has torsion axles then the brakes should go on the front axle. If the trailer has straight axles with leaf springs then they go on the rear axle. The 5 on 5 bolt pattern is not all that common. I recommend double checking just to be on the safe side. I have included a link that explains measuring bolt patterns. If you do have a 5 on 5 bolt pattern then they are likely 3500 pound axles that use L68149...

These assemblies have a 4-bolt brake mounting flange pattern. For a hub and drum I recommend part # AKHD-550-35-K.

  • Do all 3,500 lb Trailer Axles Have the Same Bearings
  • In almost all cases 3,500 lb axles will all use the same bearings. If your trailer has a Lippert or Dexter 3,500 lb axle then yeah they would be the same. But to be safe it won't hurt to pull them off and get the numbers. If you are sure you need a 5 on 5 inch bolt pattern we have the part # AKHD-550-35-K which would work and fit the spindle. This hub uses bearing numbers L68149 and L44649. I attached a help article on bolt patters for you to check out as well.

  • Adding Electric Brakes to Second Axle of Tandem Axle Carson Trailer
  • You can certainly install brake assemblies and drums on the rear axle of your tandem axle trailer, and they'll bolt right up as long as the axle has a brake mounting flange installed on it. If the rear axle uses the same bearings, and the hubs have the same wheel bolt pattern, you can use the same # AKEBRK-35R-SA and # AKEBRK-35L-SA brake assemblies and # AKHD-550-35-K hubs you used last time.

  • Can 17 Inch Diameter Wheels be Used on a 10 Inch Diameter Braking Assembly
  • There is not enough of a mating surface between the Trailer Hub and Drum Assembly part # AKHD-550-35-K and a 17" diameter trailer wheel so I cannot recommend it. It will physically fit on the hub/drum yes but as stated there is not enough contact between the two to be considered safe. Therefore, the only option I have for you to use this hub/drum would be to switch to the appropriate wheel/tire size. For this we have two options, the Provider ST205/75R15 Radial Trailer Tire with 15"...

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...
