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 Trailer Idler Hub Assembly Review

Speaker 1: Today we're going to be taking a look at the etrailer idler hub assemblies for 2,000 pound axles. Now to determine what size bearing you're going to need, we're going to remove the tire here. We're going to take you through the whole installation process, so you know how to get the old stuff off, and how to get your new stuff on.First thing we need to do is get our tire out of the way here. Now we can take the cap off of the end. Now, your cap can look a little bit different. This is not an easy lube axle, so it has a solid cap on it.

An easy lube will have a black plug there on the end so you can get to that greaser. Regardless of what type it is, we're going to use a soft hammer here, just tap it around, eventually it's going to come off.Now depending on your application, the next thing we'll need to do is remove, in this application we've got a cotter pin, or you might have a keeper that just slides over the nut. In either case, let's get that removed. So if you have a cotter pin, you just straighten it out, and then pull on your rounded side there. At that point, you can take off the nut.

Now traditionally, there's going to be a flat washer. You can see this one doesn't have it, but traditionally there'd be a flat washer that sits behind there. If you have that, you want to hang on to that and your nut. Just going to pull it on off there. That's going to take out our inner seal, our inner bearing, and our outer bearing along with the hub all at the same time.Now we'll just clean that spindle up really well, get off all the old grease, then we can start to inspect it.

Now this is what your spindle should look like once you get it cleaned up. What you're looking for is a nice smooth surface. Our outer bearing is going to ride here. Our inner bearing is going to ride here. You want to make sure there's no rust, you want to make sure there's no pitting or any areas of concern that might cause damage to those bearings.And then the larger area here is going to be your grease seal.

We also want to make sure that that's really nice and clean. We want to make sure that we don't have any pitting, that we don't have any gaps because anything like that will just allow your grease to escape out of the back. Now if you have had bearing failure on your axle, you're typically going to see some cracking here on the spindle, or you're going to see discoloration where it's turned to a purple or kind of a green. It almost looks like it's been hardened. If that's the case, you need an axle replacement. There's no sense in putting good parts on a bad axle. It's just going to wear out very rapidly. So if it looks like this, you're good to move ahead. If it doesn't look like this, you're going to need an axle replacement.Now when determining which of the two bearing kits that you're going to need, it's either going to be the kit that ends in 1K or the kit that ends in 2K. We need to determine the diameter of our spindle. Now this is either going to be one inch or one inch and 1/16. So it's very hard to determine with just a tape measure. We can't really measure the end here because those threads are smaller. That's going to be about an inch if this is an inch and 16ths. So your best bet, again, that dial caliper will bring it down, set it right on that bearing surface, 1.06. That indicates that we need the 649. If that was one flat, 1.00, we'd need the 643 bearing kit.Next issue's going to be whether it's an easy lube or a standard. This is a standard. You can see the end of the spindle's flush with the no grease inaudible 00:04:05 sticking out of it. And if you do have a grease inaudible 00:04:07 sticking out, you want to go with the easy lube style.Now there are a couple other choices that you'll have with these hubs designed for the 2,000 pound axles. One of those things are going to be the bolt pattern. Basically, you're either going to have four lugs or you're going to have five. With the four lug pattern, they're going to call this a four on four. And you can verify that. Basically you just want to measure it from the center of one stud to the center of the opposite stud. You can see that's giving us right at four inches. Once we get into the five bolt pattern, you can see this is going to be called a five on 4 1/2. So you're going to have five wheel studs that stick out. And we'll measure from the outside of one to the center of the opposing one.It's a little bit different than measuring one that's symmetrical, but you'll see that's going to give us the 4 1/2. So that'll help you to confirm that you've got the five on 4 1/2 inch bolt pattern. Now in these hubs with the five on 4 1/2, they come in two sizes. One's going to be about 5 1/4 inches in diameter. The other one's going to be 6 1/4 inches in diameter. So you want to measure from this outside edge to this outside edge to make sure you're getting the right one. Now the smaller one here that's 5 1/4, this is going to work for eight inch all the way up to your 15 inch tires.This one's what they call the large flange. This one's designed more for the 13 to 15 inch tires. And the last thing you're going to decide is what finish you want. The black ones that we have here, these are just going to be a standard paint finish. So what you're typically going to see on your utility trailers, things of that nature. The galvanized hub, which is the one that's silver here, has a galvanized coating on it. It's designed to really resist corrosion much better than just plain steel. These you're going to see a lot of times in a marine application, so your jet ski, wave runner, Jon boat kind of applications.Now in each kit, you're going to have everything that you need with the exception of the washer and the nut, and of course the keeper that comes with the nut. That's all supplied with the axle. In the hub kit, you're going to have the appropriate bearings. We've showed you how to measure that. Both bearings are going to be the same in your kit. The inner and outer, there's not really a difference between. The biggest difference is this inside diameter liked we talked how to measure the spindle.You're going to have your seal. These are all going to be the same, and this is going to fit in the backside of the hub. We'll show you how to install that. And you're going to have new lug nuts that are designed to fit the new studs. Now if you have a four on four, of course you're going to get four lug nuts. If you have the five on 4 1/2, it will come with five. And then you're going to have one of the two caps here. So we said if you have an easy lube style, that's what your cap's going to look like. It's going to allow you to remove that cap and get to the grease circuit inside, where this is going to be for the standard spindle, kind of like what we have here. This is just going to go on and cover it.Now for the grease that's going to go in your hub, you need to choose one that's going to be right for your application. For a marine style application, you want to use a marine grease. This is going to have all the lubricants we need to make sure our bearings stay in good shape. It also is going to have corrosion inhibitors. That way we're not going to have to worry about excess corrosion. For utility trailers, like the one we're working on here today, a good standard red grease or a high speed high load grease is what you're looking for. This is the ultra lube. It's available on our website, but any high temp high load grease is going to work out well for you.Now we're going to be packing all of the bearings at once. We're going to have grease all over our hands. You can use a bearing factor if you've already got one or if you want to purchase one, it could be a little bit cleaner through this process. We've got several available on our website, but the general principle of what we're going to do here. Gonna take a good amount of grease, want to get it formed into your hand pretty well, and we're going to be shoving that in between the inner portion of the bearing. You can see this little bit of a wide gap right here. We're going to shove it through there until it comes out of the top. So just use that to capture a little bit, push it in, just continue with that until it comes out of the top.We look right there on that top edge, you can see where some of it started to come up through. We want to do that all the way around on all four of our bearings. Now we're ready to get our inner bearing and seal installed. So we're going to do that from the back side of the hub. This would be the face of it. We're going to take one of our pre-greased bearings, going to drop it down in. Now there's a taper to it. We want that taper, the narrower part to be in. Going to drop it in, get it seated properly. At this point, we're going to get our seal installed. So we're going to place that on the back side of the hub, place that down and on. Use our hammer to tap it into place.The idea here is you want the seal to sit flush with the back of the hub, just like that. You see it's nice and flush all the way around. Now if you decide you don't want to purchase the seal driver tool, a lot of times you'll see a guy use a block of wood similar to this. Place that down on, and then drive it like that. Now we're going to load the hub full of grease. We want plenty in there, just don't want there to be any space between the spindle and the hub so you don't have to worry about any moisture or corrosion, things like that. inaudible 00:09:54 kind of what we're left with. You can see we've got it. Now we'll slide our hub right onto the spindle. You want to make sure it seats all the way in, and our seal goes up on that wire area.Time for us to place our outer bearing in. Now I'm going to take my washer and place it back on. You remember when we disassembled, we didn't have one of these. We want to be sure that we do. That part number is SW1000. Got that in place. Now we can thread on our nut. And if you had any damage to yours, you can replace that. Tighten that down, it's almost going to lock your hub. Back that off just a touch. Want that to be nice and free spinning, but we don't want any end play, which means we don't want to be able to move this in or out. End play would look like that.Now we'll place our cotter pin through the end of the hub there. And then we can fold each side of that pin over. Now we replaced our cotter pins. Ours we're getting pretty old, and again, those are available on our website. Part number is 165649. No end play, everything's working nice and smooth. Now we'll place our cap on there squarely. We'll just start tapping around the edge to get it in place. Put tire back on, and we'll secure that with our new lug nuts. Now we just want to head over to our other side. Going to do the same thing there, and when we get the trailer down on the ground, be sure to torque your lug nuts down to the appropriate specification. And that'll complete our look at the etrailer idler hub assemblies for 2,000 pound axles.

Fits perfect!!!!! I should have done this first instead of buying bearings and unable to remove the old bad race. While trying to remove the old race I cracked the hub and destroyed it. Then to make matters worse went to the local farm store and got what seemed like the right thing...but it was wrong too. Would have saved myself a lot of aggravation had I did my research on etrailer.com and got the right thing first. The Q&A section got me right what I needed. 10 min on the site I had ordered exectly what I needed. It arrived in two days. Almost faster than the farm store. I have spent more than two days returning parts. I will go with etrailer.com from now on. 381730

Do you have a question about this Trailer Hubs and Drum?


  • Trailer Idler Hub for 2,000 Pound Axle and 13 Inch Tires
  • There isn't enough surface area on hub # AKIHUB-545-2-1K to safely mount and use a 13 inch wheel. The hub would have to be larger to properly support a 13 inch wheel. For a hub that uses the same bearings, can take a 13 inch wheel, and also has a 5 on 4-1/2 bolt pattern we have # AKIHUB-545-2-LFEZ-1K for EZ Lube axles or # AKIHUB-545-2-LF-1K for regular axles.

  • Replacement Hubs For Trailer With 3/4 Inch Outer Diameter Spindle That Is Straight
  • The only hub we have that is currently available for a 3/4 inch spindle is Item # AH15450ECOMP. This is an agricultural hub that fits 3,000 lbs axles for 4 on 5 inch bolt pattern. It takes an inner bearing, Item # LM67048, and outer bearing, Item # LM11949. It is meant to be used for low speed (less than 20 mph) agricultural applications. It is designed for a spindle like Item # AS1500E. If you can find the actual bearing number on your old bearings and seal or can send me a bearing...

  • Replace Hub Assemblies With Bearing Buddies For A 2,000 Lb. Trailer Axle
  • Our 2,000 lb. trailer axles use both 1" and 1.06" diameter spindles. In order to determine you are receiving the correct hub assembly, you will want to use a digital caliper like part # PTW80157 to ensure you have an exact measurement. If the spindle on your trailer measures out to be 1" in diameter, then you have a 2,000 lb. axle that uses the L44643 bearing. For a 5 on 4-1/2" hub assembly designed to be used with a 2,000 lb. axle and L44643 bearings, I recommend using the Trailer...

  • The Redline Spindle # R104BT8 and our Trailer Idler Hub Assembly # AKIHUB-545-2-2K are not compatible, but you could use the Redline EZ Lube Spindle # R104BTREZ instead as it has the correct spindle measurements. For a hub that will work with the Redline Spindle # R104BT8 you can use part # AKIHUB-545-2-1K.

  • New Spindles, Hubs, Tires, and Wheels for a Canoga Concrete Mixer/Trailer
  • The LM67048 is a pretty large bearing for a trailer that only weighs 400 pounds. So there isn't a hub that uses that bearing as both the inner and the outer. But if you are willing to remove the old spindles and have new ones welded on then I do have a solution for you. First for the spindles: I recommend a BT8 spindle # SP204BT8 for a square stub or # R104BT8 for a round stub. These spindles are usually found on 2,000 pound axles so they have plenty of capacity for your cement mixer...

  • How to Determine if Trailer Can Switch to 5-Lug Hubs
  • To do this you would need to switch your hubs from the current ones that have a 4-bolt pattern to ones with a 5-bolt pattern. This may be possible but you need to know the weight rating of your axle, and also what bearings the current hub has. You will need to take apart the 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.

These are perfect for solutions where EZ Lube spindles aren't in place as they provide a grease zerk fitting as well as a way to see when you have pumped enough grease into your hub space (see...

  • To select a set of replacement idler hubs for your Fleetwood Destiny trailer you want to match up a few characteristics from your originals.

  • How to Select Replacement 5-on-4-1/2 Boat Trailer Hub Using Bearing Parts Numbers

On the page are filters you can click on to choose your required features. You want to match up the hub weight rating to your axle's capacity to ensure it can handle the weight on it.

  • Replacement Hub and Bearing Buddy for 1 inch Spindles with 5 on 4-1/2 Inch Bolt Pattern
  • Since you have a 1 inch spindle, you will want the Trailer Idler Hub Assembly for 2,000-lb Axles - 8" to 12" Wheels - 5 on 4-1/2 # AKIHUB-545-2-1K and then you will want the Bearing Buddy Grease caps that have the grease zerk. For those caps I recommend the Chrome # BB1980A or Stainless Steel # BB1980A-SS. These grease caps are spring loaded to help you get the right amount of grease and make sure the spindle and bearings are well maintained. Unfortunately that fitting correctly means...

  • Recommended Trailer Hub Assemblies to Replace Wheels with Integrated Hubs
  • Thanks for the picture. It looks like you have a spindle welded onto a frame and you just need the hub assembly. If this is like most small snowmobile trailers, then you most likely have a 1 inch straight spindle. If this is the case, I recommend the Trailer Idler Hub Assembly for 2,000-lb Axles - 8" to 12" Wheels - 5 on 4-1/2 # AKIHUB-545-2-1K. This would allow you to use standard wheels like the Kenda Karrier S-Trail ST145/R12 Radial Tire w/ 12" Galvanized Spoke Wheel - 5 on 4-1/2...

  • Selecting Replacement Idler Hubs, Wheels and Tires for Sailboat Trailer
  • For your trailer that has a 1-inch spindle and which requires hubs with part # L44643 as inner and outer bearings, we do have options shown on the linked page. These include both idler hubs like part # AKIHUB-545-2-1K that you referenced and hub/drums like # AKHD-545-2-EZ-1K. These items and the others shown have the 5-on-4-1/2-inch wheel bolt pattern. You will want to confirm your axle weight rating (on the sticker or plate that is usually attached to the axle beam itself) so that you...

  • Replacement Hubs and Springs for a Continental WC7E20 Boat Trailer
  • I called Continental and they informed me that your Continental WC7E20 boat trailer had three different spindle sizes. I have listed the spindle options for your below along with the corresponding replacement hubs. In order to determine which ones you have you will need to measure the inner and outer bearing seats on the spindle using a digital caliper like part # PTW80157. There may also be a sequences of 7 characters starting with "22-" that is stamped into the axle which can be used...

  • Would the Trailer Idler Hub # AKIHUB-545-2-1K Fit Harbor Freight Trailer Spindle
  • You would need to measure the spindle to be certain. If the spindle measures exactly .99 inch then yes the Trailer Idler Hub # AKIHUB-545-2-1K is going to fit. Where the seal rides needs to be 1.24 inches as well. 25 mm is right at .984 inches which is pretty darn close. Try measuring with a dial or digital caliper # 36554 to get an exact dimension.

  • How to Determine Correct Replacement Bearings for Older Calkins Boat Trailer
  • Oh how we wish, almost every day, that all trailer makers maintained detailed records of the components used in the fabrication of their trailers, but sadly, we do not live in that world. So, you will need to pull a wheel and hub, and check the numbers on the bearings and grease seal. I linked a photo that shows the typical placement and appearance of bearing and seal part numbers. With those part numbers in hand you can directly check our site for those parts by entering each number...

  • Trailer Idler Hub with 5 on 4-1/2 Bolt Pattern that Fits a 1 Inch Diameter Straight Spindle
  • To find the right replacement hub for a trailer you will need the inner and outer bearing numbers stamped into the sides of the bearings or the measurements of the spindle to 3 decimal places. The measurements have to be as accurate as possible so I recommend using digital calipers # PTW80157. I included a picture that shows where to measure. If the spindle diameter is 1 inch the whole length where the bearings ride then hub # AKIHUB-545-35-K will not fit. It takes 2 different bearing...

  • Fitment of etrailer Trailer Idler Hub Assemblies AKIHUB-545-2-1K My Inner and Outer Bearings L44643
  • Yes, the etrailer # AKIHUB-545-2-1K trailer idler hub assemblies will fit your spindle as long as all your measurements match the components included. Your bearings are a match so the only item you didn't specify was the grease seal. If this matches up with the 34823 (inner diameter of 1.249 inches and outer 1.983 inches) then these will work great for you. I have included a diagram to help you identify the part numbers or diameter of the seals for your convenience. We recommend using...

  • How to Select Replacement Hubs for Utility Trailer

The linked photo shows you the usual placement and appearance of bearing part numbers. Once you pull a hub and note the bearing numbers you can refer to the replacement hub page I linked for you. Just click on your inner and outer bearings to see all the hubs that use those same bearings and that will fit...

  • Finding Correct Trailer Wheels to Match Hubs for a BT8 Spindle
  • You're correct that all of the 8 inch rims we carry have a pilot hole that's in the range of 2.8 inches. Not nearly as large as the 3.275 inches you need. The best solution I recommend is replacing the hubs, unfortunately. I recommend part # AKIHUB-545-2-1K for standard spindles or part # AKIHUB-545-2-EZ-1K for EZ Lube spindles. I don't recommend boring out the pilot hole of the rim or grinding down the hub. It will very likely compromise the integrity of either part.
