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"

Holding up great. 855802

- AKIHUB-440-2-G-2K

Bought a trailer for my fishing kayak and unfortunately, the tires (and hubs) that came with it were not rated to highway use. I had a trip coming up that was several hundred miles of highway away. Ordered these hubs and they came very quickly, went on as easy as the old ones came off. I’ve pulled the trailer for around 2000 miles and everything is tight with no play. Very happy. 850684

Excellent hub for my boat trailer 798887

Every thing as promised. 797781

- AKIHUB-440-2-G-2K

Ordered new axel and hubs to replace my bent axel on older utility trailer. Instructions for ordering the correct parts was clear and easy. It was shipped the same day as ordered. Arrived in record time in great condition. Good quality. Perfect fit. 765463

- AKIHUB-440-2-G-2K

Parts worked wonderful. Easy to install and parts are still working. 653527

Excellent product. Great customer service. I needed two additional bearings and e-trailer staff was prompt in shipping the item. I am a repeat customer and will continue to buy frome-trailer. 644579

Great service 616284

- AKIHUB-440-2-G-2K

Not pretty, but good enough. 565197

They will get the job done. They are on a light duty trailer for kayaks. I wanted to use 12 inch aluminum wheels on the hubs and found that the wheels would not fit the hubs with the center caps in the wheels. The wheels fit fine without the center caps and they look good enough for me. so no problem. FYI only.

- AKIHUB-440-2-G-2K

Needed bearings for a boat trailer. For just a little more than the cost of getting bearings locally I got all new bearings and upgraded to galvanized hubs...which is a big plus for a trailer consistently backed into the water. A year later they look like new after washed. 554830

- AKIHUB-440-2-G-2K

Good quality merchandise, still as good as the day it was installed 554453

- AKIHUB-440-2-G-2K

Everything works great, good quality parts, even great customer service when I received a couple bad bearings due to ups not being careful they where on it and got replacements no problem. Recommend these hubs and business for all trailer needs 549376

- AKIHUB-440-2-G-2K

I bought a small trailer and made the mistake of not thoroughly inspecting and greasing the hubs before using it. A couple weeks later, a hub completely failed on the highway, and the internal bearings had been ground into powder. I limped home and promptly replaced both hubs with these from etrailer. The video and instructions made installation much easier, and I had both done in a couple hours (I'm not a mechanic). I upgraded the supplied outer cap with the corresponding Bearing Buddy, and this is a HUGE, very worthwhile upgrade. Etrailer should link the two together as a package! I now easily check and fill the grease every time I use it, and the hubs have been excellent. They were a great value and overall great product, and a year after purchase, they are running strong! Highly recommend. 521439

Absolutely no problems after one year. 431777

Hubs fit on my 2007 Magic Tilt Trailer. Good service and delivery time. 395871

- AKIHUB-440-2-G-2K

This is a great quality product. Prior to installation I didn't have to use wheel chocks because of gritty bearings. After installation my bearings were nicely greased making the trailer roll easy. Plus the support provided by the technical staff and the website made specification and installation very easy. Sandy J went out of her way to answer all my questions and ensure I had the best product for my application. 384162

Finished the trailer and drove from Chicago to North Carolina with a loaded trailer and no problems. 369728

- AKIHUB-440-2-G-2K

I ordered the wrong hubs at first because I made a poor assumption about my spindles. I was able to get good information both from their FAQs and from a customer service rep. I took their suggestion on the correct sized hubs and the new ones arrived a few days later. The bearings fit perfectly. Sold the wrong hubs on craigslist super fast because it would have cost too much to send them back. Thanks again for the support and accurate information! 360915

I drove the trailer from RI to Maine and back last year and the hubs were great! Cant wait for this upcoming season.

Good information and selection, very fair pricing, excellent assistance, prompt shipping. Far easier and better than driving to town and chasing down parts. 253153

  • Replacement 4-1/4 Long Idler Hub with 1 Bearings and 1.5 Grease Seal
    We do have a replacement for you with the Trailer Idler Hub Assembly # AKIHUB-440-2-G-2K. This uses inner and outer bearing # L44649 which has a 1.063" inner diameter and then a grease seal with a 1.50" inner diameter like you mentioned. From the 4 bolts in the background I'm guessing you have a 4 on 4" bolt pattern just like this hub has. The only difference is that it looks like you put bolts through your hub each time whereas this idler hub already has bolts installed. This means...

  • BTR Spindle to Fit Trailer Idler Hub for 2,000 Pound Axles

  • New Hub Assembly For Trailer With Bearings L44549
    Bearings L44549 have a 1-1/16 inch inner diameter, which is the same as the 1.063 inch inner diameter of bearings # L44649. That means the assembly you referenced, # AKIHUB-440-2-G-2K, will work. It is designed for 2,000 lb axles with BTR spindles, has a 4 on 4" bolt pattern and accommodates wheels that are 8" to 12". The assembly comes with the required bearings, races and grease seal, though for Bearing Buddies you would want # BB1980A-SS. I've added links to a video review and install...

  • How to Choose Correct Replacement Hubs for Boat Trailer with 2,200 lb Axle
    To ensure that you get the correct replacement hub assembly you need to check the part numbers on your bearings and your grease seal. If you pull the hub you should find them stamped right on the bearings and seal themselves. Luckily trailer axles have become more standardized in the recent past so I can tell you that they should be # L44649 bearings and your seal should be a 10-9 (with an inner diameter of 1.50"). If this is the case then I recommend going with galvanized hubs as they...

  • Is AxleTek Idler Hub Available Without The Race
    The # AKIHUB-440-2-G-2K idler hub is a casting that has a machine finish. This 2,000 lb hub has a galvanized finish and has a 4 on 4 wheel bolt pattern. This hub comes with the race already pressed in place and the bearings, seal, grease cap and lug nuts included. We do not carry the hub as a separate item.

  • Will Idler Hub AKIHUB-440-2-G-2K Fit on 1-Inch Spindle
    Yes, the hub you referenced, part # AKIHUB-440-2-G-2K, will fit on a 1-inch spindle since its included inner and outer bearing, part # L44649, has an inner diameter of 1.063-inches.

  • What axles go with these hubs and were do I measure old axle
    I have a solution for you. However, none of the single straight axles that we carry have any of the measurements that you have included. Our axle's mountings were wider than the 57 inches listed for the frame rails. An option that you might consider is the Timbren Axle-Less Trailer Suspension, like # A20RS4400. This axle-less system has a weight capacity of 2000 lbs and will include 4 bolt hubs with axles. This system does not use a leaf spring suspension, but a rubber AEON spring...

  • Recommended Bearing Buddy For railer Idler Hub Assembly # AKIHUB-440-2-G-2K
    The Bearing Buddy Bearing Protectors I recommend you use with the # AKIHUB-440-2-G-2K hub assembly is part # BB1980A. These protectors keep dirt and water out of the hubs and bearings and are designed to work with the # L44610 race that comes with the # AKIHUB-440-2-G-2K hub assembly.

  • Trailer Wheel Hub to Match 2,200 Pound Lippert Spindle
    We do carry the hubs and bearings that fit spindle # LC142161. The bearing kit is part # BK1-150 which uses # L44649 for both the inner and outer bearings. The hubs that fit come in either a 4 on 4 bolt pattern, like idler hub # AKIHUB-440-2-2K, or 5 on 4-1/2 bolt pattern, like part # AKIHUB-545-2-2K. We also have the same hubs galvanized; part # AKIHUB-440-2-G-2K for the 4 on 4 and part # AKIHUB-545-2-G-2K for the 5 on 4-1/2. There's also a hub and drum that fits if you need brakes...

  • 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-G-2K 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.

  • Replacement Hub and Bearing Buddys for a 2K Axle on a Boat Trailer
    Since these idler hubs will be used for a boat trailer I highly recommend going with the etrailer.com Trailer Idler Hub Assembly # AKIHUB-440-2-G-2K over the Dexter Trailer Idler Hub Assembly # 8-91-05UC1 because the eatrialer.com option has a galvanized finish that will protect it better than the powder coat finish on the Dexter option. Please note that the seals which come with these have an inner diameter of 1.500" so you will need to use part # 34823 for a grease seal instead as...

  • Recommended Trailer Hubs with 4 on 4 Inch Bolt Pattern for CE Smith Trailer Axle Beam CE33201GA
    The correct trailer hub with 4 on 4" bolt pattern to use with the CE Smith Trailer Axle Beam part # CE33201GA is the Trailer Idler Hub Assembly part # AKIHUB-440-2-G-EZ-2K. The spring seats can then be moved in 1/4" on each side to match your 47" spring center spacing. The Trailer Idler Hub Assembly part # AKIHUB-440-2-G-2K will work but you would want to use the above E-Z Lube option instead as that is what the axle has.

    The Dexter Trailer Axle with Idler Hubs - 4 on 4 Bolt Pattern - 60" Long - 2,000 lbs # 20440I-ST-60 is powder coated, but not galvanized. The best we can do to make sure it wears well with all the salt water is to instead use the same Dexter Trailer Axle Beam with Standard Spindles - 60" Long - 2,000 lbs # T20BTR-6048 but change out the assemblies.

  • Replacement Axle Tube for a Habor Freight Model 90154 Trailer
    In order to determine if we have a new axle beam that will work for you, we would first need to do some measuring. The measurements that will need to be taken are from the center of each spring seat on the axle you have now as well as the distance between the two hub faces. I have attached a photo of this for you as well. The most important measurement that you need to verify is the hub face as the spring seats can be moved. For example, if you have a hub face of 60" you can then use...

  • What is the Difference Between Trailer Hubs # AKIHUB-440-2-G-1K and # AKIHUB-440-2-G-2K
    The two hubs you mentioned, # AKIHUB-440-2-G-1K and # AKIHUB-440-2-G-2K fit different spindles. More specifically they use different bearings and seals. First, hub # AKIHUB-440-2-G-1K uses L44643, with a 1 inch inner diameter, as the inner and outer bearing, and the seal is a 34823, which has an inner diameter of 1.249 inches and outer diameter of 1.983 inches. Based on your information this sounds like the correct replacement. Check your old bearing numbers or you can take measurements...

  • How to Select Replacement Hubs for 1970s Dilly Trailer with 4-Lug Hubs
    The best way to select a new hub is to match it based on the bearing set used in the original part. New hubs must use the same bearings as your old ones in order for them to fit on your spindles, so if you can find the part numbers from your inner and outer bearings you'll be most of the way toward knowing the right replacement hubs. Please refer to the linked photo that shows the usual placement and appearance of bearing part numbers. With those part numbers you can directly search...

You will want to confirm that your existing hubs have a 5 on 4-1/2 inch wheel bolt pattern. I was unable to find any information with the 6289103 number you provided.

    Since you have the spindles with the zerk on the end, I recommend the EZ lube that you mentioned because it is designed to give you easy access to that zerk by removing the plug and not the entire cap. For this assembly, you will want the Trailer Idler Hub Assembly for 2,000-lb E-Z Lube Axles - 4 on 4 - Galvanized # AKIHUB-440-2-G-EZ-2K. If you really don't want the EZ lube access, you can use the AKIHUB-440-2-G-2K with the solid caps. We don't have any assemblies already grease packed...

  • Recommended Timbren Axle-Less System for Trailer Used for Salt Water
    The 400 lb Timbren Axle-Less Trailer Suspension System # A4WS440 has a standard black powder coat finish that does a good job protecting against the elements, but salt water will definitely be pretty harsh to this set so instead I recommend going with the kit # ASR400S02-G instead which uses a galvanized finish instead of the black powder coat. A galvanized finish will definitely hold up better to salt water and to help extend the lifespan of this kit I also recommend to spray down your...
