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"

Hubs arrived poorly packed, which resulted in the bearings being damaged in the box. Etrailer sent new bearings out however this still caused me to have to wait even longer to get my trailer back together. All of this could have been fixed by proper packaging before shipping.


Threads were flattened on some of the studs from the hubs tumbling around in the box. Brown packaging paper was in the bottom of the box but offered no protection. Hubs could have been rapped with the brown paper to prevent metal to metal damage. Just saying what it is...


Exactly what I needed to renew an older trailer.


Hubs are well built with races already pressed into place. Lugnuts included. Galvanized to keep them rust free for years. One thing that could be better is package of bearings. They were in a bag with lugnuts, grease cap, and seal. Bearings might get damaged but overall great product.


I feel very comfortable having put these on my Jet Ski Trailer. Races already installed, greased everything up and it rolls like a champ. I did have to change the seals on them due to my trailer needing a smaller diameter seal.


So quick and easy and helpful and they even upped my shipping time with no extra costl


Going to be used as a spare for the boat. A bearing was damaged in shipping, but customer service was awesome. Great company!


Fast and accurate service, even was delivered a day early


Product was exactly as described and was packaged well. The race sleeve was already installed which made assembly very easy.
Would purchase again.


Good setvice. Just what I ordered.


Will at etrailer was very helpful in determining what parts I needed on an old and not maintained jet ski trailer. The hub, bearings etc got here a day or two earlier than I thought I would get them. Installed them the following morning and everything fit perfectly.
I will use again and definitely would recommend.



Still working great.


I will always get my trailer needs here it's easy and convenient


Dust covers do not fit hub. They are to wide at the base to fit into the supplied hub. I tried sanding them down and also gently using a rubber mallet while rotating around the cover to try and get it in. Still do not fit, I'm a pretty experienced shop worker as well.

Kenny, Thank you for your review. The grease caps that come with this hub are designed to fit a 1.980 hub bore. Sometimes it can be a tight fit. If you tried tapping them in with a rubber mallet and it did not work, you may want to measure the diameter of the grease cap.

Etrailer Expert



Looks like the diameter is the right size. I think the spindles are just a little to long/deep for the cap.


Delivered timely and product as specified. Not the first time I've ordered from e-trailer and as always they are good to their word


The hubs and bearings were all mfg'd in China and seem to be just fine. They went together nicely and went onto the old groaty spindles with only a little persuasion. I think it might be worth saying that the "galvanized" finish on the hubs is really not traditional hot dipped galvanizing. . .perhaps some sort of electro plating. However, plain uncoated black iron hubs will last 20 years or more trailering into salt water, so it's certainly not an issue. The big takeaway here ought to be how great the customer service and delivery are, always, at etrailer. In this case it was Pamela who helped me work my way through what would be the right bearings and hubs. . .lovely lady who took good care of my confusion and uncertainty. And George let me know they'd shipped the morning after I ordered them at bedtime. Talk about quick! And they got to Seattle a day before promised. What's not to like!!?


etrailer is the best, I placed a order for two hub assemblies, and two wheels with tires. shortly after ordering, they quickly informed me that the hubs were, out of stock, they recommended a suitable replacement, they changed my order to reflect and everything show up just two days later. quality parts, everything fit and functioned correctly. was able to get snowmobile trailer all ready for winter much cheaper and quicker then I anticipated. thank you etrailer, would order form again and again. fast response, knowledgeable, respectful and great products!.


Bought a used homemade utility trailer and the hubs were in such a neglected shape that I gave up on them. I got the galvanized hub kits and it was a snap to get the trailer going. I had already spent about 3 hours (in a hot storage building) on the old ones. With the hub kits it only took me about 11/2 hours from start to finish. It was worth every cent for the new ones. The ordering process made it very easy to get the correct parts.
Donald H.


Hubs are ok, were sent with cheap Chinese bearings, which I refuse to use on a trailer for a $50,000 boat. Had to order USA bearings from another supplier


These fit perfect

They allowed me
to bolt on some nice American racing rims with the Ford bolt pattern

The boat trailer looks so much better now

Thank you for a good quality product and fast shipping


The fit, quality and finish on the hubs and bearings seems OK.

When tapping the first dust cover in with a rubber mallet it dented. The second was too large and I was not able to install it. The thickness of the covers is so thin I think I could crush them with my hands. I ended up using the old ones.

This does not help my expectation for the life of the bearings.




Perfect match to replace a set of rusted-out originals and everything I needed was there. Very pleased with the site with all of the information to help make the right selection. Definitely raising the bar for on line shopping for replacement parts!


Good product. Used in high salinity bay (saltwater use) has held up to corrosion.
Unfortunately I had to purchase separate size seals due to my trailer's axle size is different than what came with the kit.


Short one lug nut, other than that all products look good.
Can't give you 5 stars.



Well I can say I dont like the Chinese wheel bearings so much had one go out. First time i had a wheel bearing ever go out. It was the front one that didnt make sense. Had to leave the boat along side the Road and i didnt like that to much.


Solid replacements to the old, rusted out hubs that were on the trailer from previous lack of care... Look forward to many years of use with these, especially after treating them with FluidFilm

  • Looking For Grease Seal With 2.32" OD And 1.5" ID
    Hello Paul. We do have one grease seal that matches the specs you provided. Take a look at the Timken Grease Seal # TMK89ZR. This one has a 2.332" OD and a 1.5" ID so it appears this is the seal you are looking for.

  • 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.

  • 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,...

  • Replacement 5 On 4-1/2 Bolt Pattern Boat Trailer Hub for 1 Inch Spindle
    Before proceeding, I'd take a moment to confirm the spindle diameter, because there are two different bearing sets that are very close in dimension, so you'll want to be absolutely sure of the measurement you get. We recommend using a digital caliper like part # PTW80157. When dealing with specifying spindle/bearing ID dimensions a ruler or measuring tape typically won't provide enough accuracy which is why using a caliper is preferred. If your spindle measures 1 inch, your hub uses...

  • 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 # AKIHUB-440-2-1K 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.

  • How to Select Replacement Hub for Harbor Freight Trailer
    For a replacement hub to fit on a spindle it must use the same bearings as the original hub. Sometimes bargain trailers use odd sizes of bearings that are not readily available and so it can be tough to find suitable hubs, but you can check by pulling one of your existing hubs and removing its bearings. You can refer to the linked photo for an example of how bearing part numbers usually appear on such parts. With your bearing numbers in hand you can use the linked page to check for available...

    That number doesn't give me a cross-reference. To get a replacement you will need to pull the bearings out of the hub and on the face of both the inner and outer bearing there will be a number printed on the bearing face. If you can give me those numbers I likely can help you out with the correct replacement. I also will need to know the bolt pattern of your hub if you want to keep the same wheels. If you can't determine the bearing numbers, then you can use a digital caliper like...

    I do have hub and tire/wheel options for your application but unfortunately the dimensions you're needing for your boat trailer axle aren't close to standard measurements so you're looking at a custom order through your local trailer shop.
