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"

I received the wheels, Spindles and bearings. I did not receive the Hubs. I received Tandem-Axle Hangers Item H248 instead. I've attached a photo of what I received. Please advise next steps to get the two hubs, Items AKIHUB-440-2-G-1K TRAILER IDLER HUB ASSEMBLY 2000 LB AXLES- 4 ON 4 GALVANIZED. Shipping was great and the parts I did receive look to be very good quality. Thank you

My goodness, that was definitely a mistake on our part. Customer Service will be touch so that we can have the hubs shipped out for you.



by:

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 fit, great customer service.



by:

I thought this came pre assembled but it did not



by:

Perfect fut!!! Got our bow fishing boast ready to hit the water!!



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:

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:

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:

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:

Hubs look good. No problems.



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:

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



by:

Made my conversion easy



by:

Great product!



by:

great product



by:

Great product! Made quick work of rebuilding my axle.



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:

Good hub, good price. Purchased for a vintage Alloy brand boat trailer. Perfect replacement . Matches the hub on the other side which I purchased from Etrailer some years ago. Nice to have this stability in the products offered. The only addition I made was to also order a double lipped grease seal at the time of purchase, since this is a boat trailer application.

Norman C.

4/30/2021

After a year of service, hub is working fine. The double lipped grease seals I added are also doing their job. No complaints!



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.

  • Recommended Bearing Buddys For 2,000-Lb Axler Idler Hub Assembly
    For your Idler Hub Assembly, part # AKIHUB-440-2-G-1K the Bearing Buddy that is designed to fit is part # BB1980A. These are chrome plated and include rubber covers. We also have the stainless steel Bearing Buddy that will also work. For those you would order part # BB1980A-SS.

  • How to Accurately Find Replacement Bearing
    There is no way to know for sure with a measurement of 15/16 of an inch what the correct bearing is. The only way to know the correct bearing is to use a digital caliper and measure your spindle to the thousandths of an inch where the bearing rides. The reason for that is because the measurements of some bearings are so similar; bearing # 1779 has a 0.938 inch inner diameter, bearing # L44643 has a 1.00 inch inner diameter and bearing # L44649 has a 1.063" inner diameter.

  • Can a 4 Lug Hub Be Swapped WIth a 5 Lug Hub
    We do not, but as long as the new lug hubs use the same bearings as the current hubs you can just swap them out. For instance, if your current hubs used the L44643 bearing you can use both the Trailer Idler Hub Assembly for 2,000-lb Axles # AKIHUB-440-2-G-1K to replace the 5 lug hub # AKIHUB-545-2-G-1K. You'll just need to also keep in mind that the wheels you currently use won't work since the bolt pattern is different.

  • Replacement Trailer Hub for Seadoo Trailer 4 on 4 Bolt Pattern
    There are 3 possible hubs for your trailer. To determine the correct hub you will need to remove one of the hubs it check for the correct bearing/spindle size. If you can read the numbers on the bearing you are looking for L44643 or L44649. If unable to read bearing numbers you can measure the spindle with a Digital Caliper # PTW80157. 1" Spindle(L44643) - # AKIHUB-440-2-G-1K for non EZ Lube Axle - # AKIHUB-440-2-G-EZ-1K for EZ Lube Axle 1.063" Spindle (L44649) - # AKIHUB-440-2-G-2K...

  • 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.

  • Seeking Replacement Galvanized Hub Fit for Boat Trailer
    To get the correct hubs for you, I need to have more information. You can either pull a hub and look at the face of the inner and outer bearing for the number printed on each bearing. If you don't want to pull the grease seal then the diameter of your axle spindles can be measured with a digital caliper like # PTW80157 at the bearing and seal locations. I've linked the page to all the 4 on 4 inch options, but if you give me measurements or bearing numbers I'll be happy to confirm the...

  • How to Determine Which Replacement Hubs for a 2000 Flying Scot Trailex Boat Trailer
    Unfortunately, we aren't able to look up the hubs used by a particular make and model trailer, although I sure wish would could as it would make life a lot easier! The good news is that it's pretty simple to determine which hubs you need. The easiest way to determine which replacement hubs would be needed would be to pull one of the hubs and get the reference number engraved/stamped/etched onto the side of the cages that hold the roller bearings.

    You can make sure new trailer wheels will fit on your trailer's hubs by matching up their dimensions and bolt pattern. The part # AM22318HWT that you referenced is a 12 x 4-inch wheel that has a 4-on-4-inch bolt pattern. These wheels fit on 1/2-inch diameter wheel studs like those on idler hub # AKIHUB-440-2-G-1K. The tire sizes that can fit on a 12 x 4 wheel like these include 4.80-12, 5.30-12 and 145/80-12. These tires will have a slightly different overall diameter when mounted on either...

  • Does a Washer go Between the Outside Bearing and the Axle Nut?
    Yes there should be a thrust bearing/washer between the outer bearing and the nut that goes on to protect the bearing. What you want is Washer For 1" Spindle part # SW1000. This will replace the missing one and get you back on the road. Keep in mind this is for the very common 1" spindle diameter which is what the hub you looked at uses if you have a different size than this let me know.

    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...

    It sounds like you are needing the Trailer Idler Hub Assembly # AKIHUB-440-2-G-1K for your trailer. This hub fits the BT8 Spindle # TRU59FR which is 1" in diameter and has a length of 4-1/4" long from the inner bearing landing to the end of the threads. The Idler Hub Assembly # AKIHUB-440-2-G-2K you found fits a BTR Spindle # TRU44FR which has a diameter of 1.063" for the hub bearings.

  • 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...

    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.

    The Dexter Trailer Idler Hub Assembly # 8-91-05UC1 comes with the Bearings # L44649. You do have the option to order 2 of the Trailer Hub Bearing # L44643 and simply use these when you install the hub as they both use the same size Race # L44610.

    So there are only a couple ways to definitively know what replacement hub you need, and this is based on a bit of necessary information. First, you need to know the weight rating of your axle, and also what bearings your current hub has, as spindle size is an indicator but doesn't have the required info. You will need to take apart your 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....

  • 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.

  • Availability Of Trailer Hubs For A Harbor Freight Trailer With A 25 mm Spindle
    I can certainly point you in the right direction. The closest thing we have to a 25 mm (0.984") spindle will be hubs that fit a 1" (25.4 mm) straight spindle. For example the Trailer Idler Hub # AKIHUB-440-2-G-1K uses a # L44643 bearing (1" inner diameter). This is a fairly common size for a 2,000 lb trailer axle, which harbor freight trailers are known to use.

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.
