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.

After toasting a set of bearings in my old hubs on a light boat trailer, I decided to go ahead and replace the whole set. My old hubs didn't have studs / lugnuts, so this was a great upgrade. Everything worked fine replacing on a BT8 spindle, except I had to replace the washer between the outer bearing and castle nut with a thinner washer. The SW1000 washer was too thick and wouldn't allow cotter pin to be installed. Would recommend to a friend! 464284

We purchase literally hundreds of these hub assemblies. We are a manufacturer of turf renovation machinery. We purchase the best equipment we can find at a competitive price. These units are consistently quality hubs, never a single unit that had any defects. You can easily spend twice the money and not gain anything for the extra money spent. Nice to have quality products, quick delivery and reasonable pricing consistently. 563766

Great products and prices. These 3,500 lb brake drum/hubs appear to be well made and will be used to complete a new axle I've had a few years to construct a tandem axle trailer. I plan to order more of these for other axles as well. The 4 lug X 4" BC hubs are also well made and will be used on a hydraulic log splitter and small yard waste dump trailer to replace one-piece wheel hubs. This will allow me to use some surplus 8" tires on 4 lug wheels I have left over from some small trailer projects. 463326

The products were perfect and brought my 25 year old trailer back to new! The most wonderful part of the repair was talking to Carla at the help desk. I could not reach a comfort level as to which bearing/seal/hub kit to buy and she was exceedingly patient in having me measure mic clearances and direct me to etrailer's appropriate web sites so we could both see and talk about the same thing. Then, when I was 99% sure of the right kit, I expressed concern about one measurement that HAD to be correct or I would be shipping it all back. This was not available in the product description so she offered to go find the kit, get the measurement and call me back! Measurement confirmed! I ordered and have now installed. Carla went above and beyond.......thank you Carla and thank you etrailer! Joe in Oregon 573939

This was everything I needed to replace the bearings and hubs on a 4X8 utility trailer except the grease and cotter-pin. No issues with quality; no issues with parts not fitting. Everything I needed was in the box, and etrailer even had a useful video to show me how to replace it all. Total time to replace the hubs was about an hour, and most of that was packing the new bearings and cleaning off 30 years of grease from my trailer axles. No issues/ no problems. First rate product at an unbeatable price. 571289

This hub kit was perfect. The hub design, the bearings, the grease seal, the cap and the lug nuts all fit together. The cap was a little tight to get on but otherwise it all went together very good. I'm very happy with my purchase. Also very happy with the etrailer assistant, Susan H. She walked me through each step to make sure I ordered all the right parts. 569483

Had a cracked hub on a kayak trailer build. Heard about e trailer and wow. What I needed I also had to pay shipping but even then the hubs was 20 a piece cheaper online and 30 a piece cheaper than local. These hubs was upgrade so I don’t have to fight bolts when putting wheel on. Great price and product. I am hooked on getting all my stuff from them in the future. They even threw in the quicker shipping with no additional cost to me. You can see what I had and got in the pictures 539155

I ordered and installed a pair of Trailer Hub Assemblies from etrailer to replace the failed and rusted hub assemblies on my motorcycle trailer. The new parts fit perfectly and the job was easy to complete thanks to the provided instructions. The sales person at etrailer was very helpful in finding the correct hub assemblies for my particular trailer and the new assemblies were mailed within 24 hours of my order. I also appreciated the tremendous value, I spent much less than what I expected to pay for a hub assembly. Thanks etrailer, I will use you again! 359031

Excellent product - received hub, bearings and seals in super fast time. We were able to get our old boat trailer up and running in no time. The service reps at etrailer are super helpful in making sure you get the correct product. Great pricing, too! 572685

The kit worked very well for my small trailer. All parts were exact and the fit was perfect. This complete hub kit was less expensive from etrailer than just the bearings and race from my local auto parts store. For less than $100 I got two kits with a new tire and rim. My main concern with this axle project was pressing in the new race into the old hub. With this kit the race is pressed in when you receive it. This was a very good value and saved considerable time. And the shipping was quicker than anticipated. 401149

Overall product quality is pretty good for the price , no issues with casting or bearings which is what counts . Dust covers are the usual stamped steel so there is a pretty good burr lip that needs a bevel to help start it inside the hub bore - just be aware of it and it makes the job much easier . I used these hubs to do a conversion on a garden tractor - going from very small lightweight ball bearing stamped style 1" inside flanged push-in type to trailer hubs and 8" - 4 bolt trailer rims - can't say enough about how much better this upgrade works and much more serviceable on my old Wheel Horse . For those running a loader on the larger garden tractors this upgrade is a must unless you like buying new wheel bearings constantly - this conversion will last a lifetime if cared for properly . E-Trailer is always great at answering questions and will help with dimensions if you ask - that is priceless in today's world of non-support retailers , wish other outlets would handle customer service like E-Trailer . I won't hesitate for a second to buy needed parts from these guys - good pricing , fast shipping and details that others won't take the time to include with product listings . Got my trailer brake controllers for both trucks , several other build parts to wire my trailer for a full 7-wire system including fused power feed and reverse lights - thrilled with everything I've ever bought from them . Will be back in the future , that's for sure . Sarge 320096

Everything went perfect with this purchase, delivery and installation. The online video was extremely helpful and made the work go easy when I did the installation. I agree with other reviews Do Not Toss your old dust caps, never could get the new ones on, but that was minor in grand scheme of things. I would recommend getting cotter pins while ordering hubs for those attempting this with as little skill as I have. This project went very smooth with all the Etrailer information 501276

For those who has the Harbor Freight 62645 (40-1/2? x 48?) utility trailer that has the .98**" shaft and 1.181" (30mm) seal shaft . Yes this is your hub, just need to replace the kit seal with a National 473426 seal. For my purpose, changing from the 4.80-12 4 ply to a 145R12 10 ply tires I used 1" 4"x4" wheel spacers. The wheel studs was to long, so I purchased and installed the (K12WB169) Kodiak Wheel Bolt - 1/2 Diameter X 1-7/10 Long. Perfect fit! This kit has a little bit heavier bearings, so the castle nut may have to filed a little bit to get the cotter in, due to the so called Chinese precision notches. No one locally have a replacement castles nuts. I will replace these a later when I find better quality ones. 471218

Hub and associated parts arrived quickly and were packaged well. No issues at all. The site as a whole is great and has many good Q &A areas that helped me ensure I was ordering the right part for my needs. Great hub for the price and the races being already installed into the hub was a nice touch. This is THE place to get your trailer parts from. I am using these hubs to rebuild a small utility trailer and to convert the tires from the 8" tires to ATV tires. The hubs that were on the trailer were the old style with the lug nuts that screw into the hub. Since I was going to need an adapter from 4 on 4 to 4 on 4 - 110 I needed the conventional hubs to allow the adapters to bolt up and at the same time, replace the probably 15 yr old hubs that were on the trailer. 269342

Bought an old boat trailer that had serious wheel hub issues. Measured the spindle and checked all my local resources including 2 auto parts stores. No go. Called and talked to Samantha and she said these will work. Much to my surprise, they worked awesome. Great kit with all you need except the castle nut and cotter pin (save your old ones). Easy to install and should last a long time with some basic maintenance. Price was great for what I received. Give Etrailer a call and let them find what's going to work for you. 499073

This hub assembly is for a spindle 4 inches in length. Etrailer has done a fantastic job of putting all the specs for this product on the product webpage expect the spindle length. If you have an older trailer, you may have a 3 inch spindle. Double check your spindle length before you order. This product ships un-assembled and without grease. Bearings and hubs that have been greased and assembled in preparation for installation are non-refundable if it does not fit the spindle. Don't make my mistakes. 651734

These were the perfect fix for my friends old boat trailer. His axles were getting pitted where the grease seal rides so I fixed that with Speedi-sleeves.

The 4 bolt hubs arrived very timely and were packed well. I've already assembled them and they seem to be very good quality. The prices are some of the lowest. Very pleased. One helpful hint for putting on the grease caps is to use a 2" piece of conduit over the cap that fits on the ridge of the cap to hammer (tap) them in. Do not use a hammer on the top of the cap. I will use etrailer.com again. 633437

Cheap price. Lightning fast shipping. Great product. The only thing that could make it better is if it came with the outer washer an cotter pin but no biggie. They're like 80 cents each so I could just run to the hardware storev an grab some. Fitment was spot on thanks dust cap was a little tough to get on but I just slbent the sides a little an she went right on. 615075

Nice hubs, but the dust covers are flimsy. I couldn’t tap them into the hubs without distorting them, rendering them useless. I cleaned up an old set of Bearing Buddies to cap them. 582872

I needed a few things. A hitch, wiring and accessories for my new Mustang on one order, and a hub kit with bearings and seals and tires for my small utility trailer on another. etrailer had it all, the site is easy to negotiate, prices are OK, quality is good, delivery time was excellent and everything was in stock. The hitch was poking out of the box when it arrived so a little touch up paint on the points fixed that, my only gripe. Their helpful hints section is also very welcome. Next time I need anything towing related, etrailer will be my first go-to place. 580005

  • How to Tell if Trailer has a BT8 or BTR Spindle Installed
  • A BT8 spindle would have a diameter of .99 of an inch where the bearings would both install and would have a diameter of 1.24 where the great seal would ride. That would require a hub part # 8-91-05UC1 for an idler hub. A BTR spindle would have dimensions of 1.06 inch for outer and inner bearing plus 1.50 inch where grease seal would install. That would require an idler hub part # AKIHUB-545-2-G-2K.

  • What Does BTR and BT8 Mean when Picking Out Replacement Trailer Hub
  • BTR and BT8 are the reference numbers for a standard trailer spindle size. When picking out a hub for a trailer you have to make sure that the hub is designed to fit the spindle. What you will need to do is measure spindles on your trailer where the bearings ride and with the info we will be able to tell what hubs will fit. If the spindles are .99 inch and .99 inch where the bearings ride you have a BT8 spindle and would need # AKIHUB-440-2-1K. If the spindles are 1.06 and 1.06 inch...

  • Replacement Hub for Old Boat Trailer with 07100 Bearing
  • The 07100 bearing number you referenced is an older bearing that has the same dimensions as # L44643. If both the inner and outer bearings on your existing trailer are the 07100/ # L44643, and the hub has a 4 on 4 inch bolt pattern, the correct replacement hub will be the etrailer.com # AKIHUB-440-2-1K. This hub assembly is designed for 2,000 pound axles and will fit wheel sizes of 8 inches to 12 inches. The bearings, races and seal are all included. I have attached a short video...

  • How to Find the Correct Replacement Hub
  • There is a way to find the correct replacement hub, but not by the size of the hub face. In order to find the correct replacement hubs for your trailer, you need to first know what bearings your current hub has; you should be able to see the part number stamped directly on them. If you are unable to find them, you need to use a digital caliper such as # 301-17068 and measure your spindle to the thousandths of an inch where the bearings and grease seal ride. You can use the photo I've attached...

  • Trailer Hubs and Bearing Buddies for Trailer Spindles with 1 Inch Diameter
  • It sounds like your spindle uses L44643 bearings, There are a lot of hubs that use those bearings and have a 4 on 4 bolt pattern such as # AKIHUB-440-2-1K. However, the 1968 Bearing Buddies are designed to fit a hub that uses outer bearing M-12649 or 07100 which are not common. The hubs that fit your spindle take the 1.98 Bearing Buddies such as # BB1980A-SS or # BB1980A.

  • Replacement Hubs with L44649 Bearings and Replacement Hubs with L44643 Bearings
  • If the spindle is 1 inch in diameter exactly at both bearing locations then they are L44643 bearings. If it is slightly over 1 inch then they are L44649 bearings. You can also measure the inner diameter of the bearing and that will help. And if you can email me a picture I might be able to make it out. I have seen a lot of bearings over the years! If you do end up having L44649 bearings AND the spindles have grease fittings on the ends then you can use hub # 8-91-05UC1-EZ. If they are...

  • Selecting New Hub to Replace Old Hub That Used Bolts
  • Strictly speaking you could change your hubs by installing threaded studs that would accept lug nuts in place of the bolts that currently secure your wheels. But honestly, I would just replace the hubs since yours are fairly old at this point. The keys to selecting new hubs for your boat trailer are 1) matching up their weight rating to the axle rating; 2) matching the wheel bolt pattern, in this case 4-on-4; and 3) matching up the bearings used in the old and new hubs. A new hub...

  • Finding Replacement Hubs for 1998 Triton XT Snowmobile Trailer
  • In order to choose the correct replacement hubs for your 1998 Triton XT Trailer, you will first want to pull the existing hubs on the trailer to check for the bearing numbers. These should be stamped onto the bearings themselves. If you cannot locate the numbers, you can also take a few measurements along the trailer spindle where the bearings will sit. I have attached an image that points out where these measurements should be taken. I recommend using a digital caliper like # PTW80157,...

  • What Is the Difference Between a BTR and BT8 Spindle
  • The BTR and BT8 denotations refer to the spindle, not the trailer hub. The difference between a BTR and BT8 spindle is that the BTR spindle uses a 1.063" diameter L44649 bearing and the BT8 spindle uses a 0.99" diameter L44643 bearing. In order to find out which you have you will need to pull the hub and either measure the spindle or look for the bearing numbers on the bearing. If you have BTR spindles then you can use part # AKIHUB-440-2-2K but if you have BT8 spindles then you will...

  • Determining BT8 or BTR Spindle on Trailer
  • The easiest way will be to pull off a trailer wheel and hub and then use a caliper like # PTW80157 to measure the spindle diameter where the bearings ride. If the diameter is .99 then you have the BT8 spindle or if it's 1.06 you have the BTR. The trailer hub # AKIHUB-440-2-1K you referenced would be what you'd need if you have the BT8. If instead you have the BTR you'd want the part # AKIHUB-440-2-2K.

  • 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...

  • 4-on-4 Bolt Pattern Hub/Drum for Use on 2K-Rated Axle
  • Matching up new hub/drum assemblies to your Dexter P-11 axle just requires matching up the bearings used in the original hubs and confirming the axle weight rating. New hubs have to use the same bearings in order to fit on your spindles and your new pair of hubs need to be rated for the capacity of your axle. Usually a plate or sticker on the axle itself (or the trailer) will tell you this. I see that you selected 7-inch brake assemblies for a 2K axle. For 4-bolt hub/drums you can use...

  • Can Trailer Spindle # SP204BT8 Be Used with Trailer Hub # 34822BX
  • Yes, you can use hub # AKIHUB-440-2-1K with spindle # SP204BT8. These two parts are compatible. Spindles get welded onto the ends of an axle. This is a precision job because it has to be perfectly straight and concentric or the trailer will ride poorly and you will have faster tire wear and faster wear on the suspension. I strongly recommend having a qualified professional with experiencing working on trailers install the spindles. The other option is to get a whole new axle with the...

  • Replacement for Dexter 8-91A Hub
  • I did some research and there is no direct replacement for your hub due to how old it is. So in order to find the correct replacement, you will need to know the bearing numbers of your current hub because the information you gave is irrelevant. If you are unable to find them, you would need to use a digital caliper such as # PTW80157 and measure your spindle to the thousandths of an inch where the bearings ride. You can use the photo I've attached to see exactly where you need to measure. There...

  • Trailer Hub Recommendation for Spindle that Measures 1 inch and 1.25 inch
  • Your spindle dimensions match the BT8 spindle so for a replacement hub the # AKIHUB-440-2-1K will fit if you have a 4 on 4 inch bolt pattern or the part # AKIHUB-545-2-1K for a hub with a 5 on 4-1/2 inch bolt pattern.

  • 4 Lug Hub Replacement for Hub Marked BT100
  • From previous customers with your hub we have found the BT100 hub to be one that has bearing numbers L44643 for the inner and outer bearings. So for a hub that will fit and has the right bolt pattern you'd need the part # AKIHUB-440-2-1K.

  • Recommended Replacement Hub For Older Boat Trailer With 07100 Bearings
  • We may have a replacement hub that will work for you. The 07100 bearing you mentioned has an inner diameter of 1 inch. The bearing we offer that has the same inner diameter is part # L44643. The trailer hub assembly I recommend is the Trailer Idler Hub Assembly, part # AKIHUB-440-2-1K. This hub includes bearings, races, seal, grease cap, wheel bolts and lug nuts, and is designed for 2,000-lb axles. The hub has a 4 on 4 wheel bolt pattern.

  • Replacement Spindles and Hubs for Trailer with L44643 Bearings
  • In most cases it's easier and less money/headache to just replace the entire axle. Welding on spindles is a specialized job that only certain welders have equipment for and by time you go that route it's just easier to replace the axle. But that being said square axles are harder to find as that's not the common shape. You'd have to find a local trailer shop to you who can order you in custom axles though as we don't have what you are looking for. For new hubs though the part #...
