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"

Parts fit perfect. I just wish the kit included a cotter pin.
The old hubs were frozen in place and the grease inside was completely dried, including the bearings. I opted to replace entire hub as I new I would damage something trying to get the old races out of the old hubs. Clean up the spindles and proceed with the install. It was fast and easy.



by:

I thought the hubs and bearings looked good and the install went OK. Took the boat out for one fishing trip and get back home to see both sides are trashed. The left side completely pushed my bearing buddy out and looks like it may have been riding on the axle spindle. I don't know if the outer races weren't completely seated in the hub when they were shipped or if the bearings are absolute junk. If they are going to ship the hubs with the races pre-installed they should be seated properly if you ask me.



by:

Great replacement for Hobie Kayak trailer used in saltwater... hubs look like they will hold up better being galvanized. Great bearing and seal replacement.... great fit.

Shipping was very fast and parts were spot on.



by:

Just as described. Nicely packaged. Quality parts at a great price. It would be nice if a cotter pin was included. Because if your not a mechanic like me and have some. You are going to have to make a trip to the parts store to complete your project. Other than that I highly recommend getting your parts here. I used these hub to convert a log splitter to a hub and wheel assembly instead of the one piece. Worked perfectly.



by:

Parts arrived as shown and were easily installed. They were used on my boat trailer so the galvanized hubs were a perfect fit. Etrailer is easy to work with and communicates the progress of your order via email.



by:

Great price. However, after tightening the bearings down so the wheel moves freely, there seems to be a little bit of a grinding noise. If I loosen it too much, then there's some wobble in the hub. Will know the next time I take the boat out. If I hear any grinding and if the hub gets warm, we'll have to contact customer service. For the price, if I get 2 years out of the bearings I'd be happy. I would have preferred a better bearings that were smooth, maybe higher quality like a timken.



by:

Seems in this day and age something always comes up. Not with thease hubs and bearings. Everything was as described and fit like a glove. I'm really looking forward to getting my boat out now.



by:

Had a strange hub that used lug studs and one of the threads stripped. This item was cheap, shipped quick, and put my utility trailer back in service. No complaints, would buy again.



by:

Good part. Unfortunately the grease seals didn't hold up. Need to replace them.



by:

Great product! Made quick work of rebuilding my axle.



by:

As always e.trailer delivered quickly and everything was well packaged. I've been using e.trailer a lot recently and they are on top of their game.



by:

You can’t beat Etrailer for service and availability of parts.



by:

I purchased this a pair of these hubs for my huskee 20 ton log splitter. I got tired of taking the bearings out when I needed to fix a flat or replace the tire. Kit included everything listed and I got replacement cotter pins from the local hardware store. The upgrade was easier than expected with everything fitting right down to the rear bearing seal!!

I purchased 2 tires and rims (item number AM30040) to match up to the new hubs. They are OEM tires and an upgrade to load rating that originally came with the splitter.

I would highly recommend this upgrade! product came nicely boxed up and came a few days earlier than expected.

one star taken off rating because I don't know how long they will last but they are excellent so far



by:

Excellent hub for my utility trailer at a most reasonable price. Shipped quickly, seems to be a quality hub!



by:

The packing job was as bad as it gets. Spindles, hubs, and a tin of grease just chucked into the middle of the box between two wheels without a care in the world. That level of "I don't give a $#!+" from the warehouse crew is highly irritating. Otherwise would have left a better review as the products and service from etrailer are usually quite good. All it takes is for one link in the chain to break and it ruins the whole experience.



by:

I should have known but I didn't read reviews. No Cotter pin! That is such an easy thing to add but they don't. It requires a trip to the store making this a pain in the rear. Would be a cool bonus to add a new nut as well. I think the instructions are not very in depth either but still a good product.



by:

I received the parts earlier than I expected and they were the correct ones. When I ordered them I was not sure exactly what I needed. I am very pleased with the service and the product.
Thank you. Dale C



by:

Well done, professional and prompt. Thank you very much. Looking forward to doing business with you again.

Fits perfect.Easy installation.

Great place to do business with. Correct product, good price and fast shipping.

Great thank you.



by:

I really appreciate the customer service, I received from Madison H she was very helpful, much respect for her!



by:

I ordered hubs with 4 lug on 4" center and received hubs 5 lug on 41/2" center.

The order was correct, the picker grabbed the wrong items and no one appears to have checked their work.


Not happy at all. This completely tanks my departure plans.

  • Hub with 4 Lug Bolt Pattern that Uses Bearing Numbers L44649
    The two bearings you mentioned have different inner diameters. The # L44643 has an inner diameter that is exactly 1 inch and the # L44649 is 1.06 inch. This may not seem like a lot but it's a big enough difference to prevent the hub you have now from fitting your spindle (you may already know this). The seals are slightly different diameters too. Since you wouldn't be able to swap out the bearings of your current hub to the correct size you need (the hub won't match), the only solution...

  • 4 On 4" Lug Pattern Idler Hubs Galvanized That Use L44643 Bearings For 2,000LB Boat Trailer Axle
    You are needing our Trailer Idler Hub Assembly # AKIHUB-440-2-G-1K. It is identical to the Trailer Idler Hub Assembly # AKIHUB-440-2-G-2K that you have on hold only it has the # L44643 Bearings that you need.

  • Overall Length of Trailer Idler Hub Assembly for 2,000 lb Axles
    By "oal" I believe you are asking about the overall length; I measured the Trailer Idler Hub Assembly # AKIHUB-440-2-G-1K and found it was 4-1/4" long.

  • Lug Nut Torque Specification with Trailer Idler Hub Assembly AKIHUB-440-2-G-1K
    The # AKIHUB-440-2-G-1K uses a 1/2 inch wheel stud. 90-95 ft lbs of torque is probably about right for the lug nuts. If you check out the lug nut torque chart that I attached you will see that nearly all the torque specs are that and higher. The wheel material also affects torque ratings, so it is lower for aluminum and higher for steel.

    For a 1 inch spindle on a boat trailer, I recommend the Trailer Idler Hub Assembly for 2,000-lb Axles - 5 on 4-1/2 - Galvanized # AKIHUB-545-2-G-1K or the Trailer Idler Hub Assembly for 2,000-lb Axles - 4 on 4 - Galvanized # AKIHUB-440-2-G-1K.

  • Can a 5-Lug Trailer Hub Replace a 4-Lug if the Bearings and Seals are the Same
    Yes, you can go with hub # AKIHUB-545-2-G-1K since it uses the same bearings and seal size as your regular hub # AKIHUB-440-2-G-1K. Keep in mind that you will also have to switch to wheels with the 5 on 4-1/2 bolt pattern. I would assume you are wanting to go with 12 inch tires which is the largest either of these hubs can take. I have included a link to all of the wheel and tire and wheel combos we have in the 12 inch size with 5 on 4-1/2 bolt pattern.

  • 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...

    Yes, we do have a couple of hubs that will fit a 1" diameter spindle. Both will work with a spindle that uses a # L44643 inner and outer bearing. You will just want to confirm what lug pattern you currently have before purchasing so you do not have to change your wheels. I have listed them below along with an installation video. For a 5 on 4-1/2 lug nut pattern you will want the etrailer Idler Hub Assembly for 2K Axles item # AKIHUB-545-2-1K. For a 4 on 4 lug nut pattern you will want...

  • Trailer Hub With 4 on 4 Bolt Pattern & L44643 Bearings
    Thank you for that detailed info it was super helpful and we do have hubs with a 4 on 4" bolt pattern that use # L44643 bearings. You can go with either a galvanized or non-galvanized option, whichever you prefer: - Galvanized: Trailer Idler Hub Assembly # AKIHUB-440-2-G-1K - Non-Galvanized: Trailer Idler Hub Assembly # AKIHUB-440-2-1K These do include the bearings, races, and seal as well so you don't have to purchase anything separately.

  • Recommended Replacement Hubs For 1950s Boat Trailer
    The best way to fid replacement hubs for your boat trailer is to find the number stamped on the bearings in the hub you have. I have attached a drawing that shows where the numbers can be found. If you can not find the bearing numbers, you can use a digital caliper like part # PTW80157 and measure the spindle in the noted locations. The trailer hub assembly I recommend for a 1.25 inch straight spindle is the Trailer Idler Hub Assembly, part # AKIHUB-440-2-1K. This assembly is designed...

  • Measurements Needed to Find Replacement Hubs
    There are a number of measurements you'll need in order to find the correct hubs, and you'll need to use a digital caliper to measure your spindle to the thousandths of an inch where the bearings and grease seal ride, like in the photo I added. You will also need to know your axle capacity (which should be stamped on the axle itself) and wheel bolt pattern. If you aren't sure what your wheel bolt pattern is I have linked a help article below which details how to find it. For example,...

  • Trailer Hub For BT8 Spindle With 4 on 4 Bolt Pattern For Boat Trailer
    Thank you for that information, and we do have a hub that fits a BT8 spindle and has a 4 on 4 bolt pattern. This hub is for a 2,000 lb axle, and is galvanized to protect it from corrosion, which is what you'll need for a boat trailer. The correct hub that fits a BT8 spindle with a 4 on 4 bolt pattern is the following: - Trailer Idler Hub Assembly for 2,000-lb Axles - 4 on 4 - Galvanized # AKIHUB-440-2-G-1K If you don't have a bearing packer I recommend the Bearing Packer # PTW1218.

  • Replacement 4 Bolt Idler Hub For 1" Spindle
    Based on the measurements of your spindle you provided the most likely replacement hub is the Trailer Idler Hub Assembly for 2,000-lb Axles # AKIHUB-440-2-G-1K which uses Inner and Outer Bearing # L44643 which is 1" I.D and uses the 4 on 4 bolt pattern. The reason I say most likely is that the most common 4 lug bolt pattern is 4 on 4, but there is a 4 on 5 option. To confirm your bolt pattern you will need to measure the distance between the holes in your wheels according to the article...

  • Replacement Hubs with 4 on 4 Bolt Pattern for 1" Non-Tapered Spindle on Boat Trailer with 12" Wheels
    A non-tapered spindle with a 1.00" diameter will use an # L44643 inner and outer bearing, so you'll want to use the Trailer Idler Hub Assembly for 2,000-lb Axles - 4 on 4 - Galvanized # AKIHUB-440-2-G-1K, which have a 4 on 4 bolt pattern and work with 12" wheels. These hubs are galvanized so they're ideal for boat trailers, have a 2000-lbs capacity and are the only available capacity that will fit on those spindles. I've linked a short review video of these for you to have a look at.

  • Picking Out Replacement Hub for 1,000 lb Motorcycle Trailer
    To pick out correct hub for your trailer we would need more info. We would need to know the wheel bolt pattern, the current bearing numbers OR diameter of the spindle where the bearings rides or axle brand and capacity. I would be willing to bet your trailer needs a 2,000 lb axle hub like the part # AKIHUB-545-2-G-2K for a 5 bolt hub or part # AKIHUB-440-2-G-1K for a 4 bolt.

  • Recommended Hub for a Boat Trailer w/ L44649 Inner and Outer Bearings
    The bearings that go on a 1.06" spindle are item # L44649. These are found in this configuration on 2,000 lbs - 2,700 lbs axles. If you can find it there is typically an axle tag or engraving somewhere on the axle that'll have a serial number or even the capacity on it. To replace the hub you will need one of the following depending on your bolt pattern: 4 on 4 - Galvanized - item # AKIHUB-440-2-G-2K 5 on 4-1/2 - Galvanized - Item # CE13315 Feel free to email me back with any additional...

  • Replacement Hub for Spindle With 1" Inner Diameter Bearings
    The # AKIHUB-545-2-G-2K uses # L44649 bearings with an inner diameter of 1.063" and also has a 5 on 4-1/2 bolt pattern. Since you need # L44643 bearings with an ID of 1" and a 4 on 4 bolt pattern the correct part would be the Trailer Idler Hub Assembly for 2,000-lb Axles - 4 on 4 - Galvanized # AKIHUB-440-2-G-1K. If you have an easy grease/EZ Lube axle then you would need the Easy Grease Trailer Idler Hub Assembly for 2K Axles - 4 on 4 - Galvanized # AKIHUB-440-2-G-EZ-1K instead.
