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"

They work as advertised. I have no complaints. I use this trailer to pull two kayaks and have taken it from Oklahoma to Little Rock twice, to Mississippi twice and back and forth to local lakes with no issues.

Still have no issues. Lube a couple times a year, depending on use. I am happy with the purchase!

Great fit on our old trailer. We were worried we'd never find the right hubs for our '95 Haulin' wagon. These slipped right on and we're ready to roll again! Arrived in perfect condition and record time.


Easy to install


good replacement for old hub that got messed up from bearing going out

Still working fine

I was struggling to find the correct hub kit for my boat trailer because etrailer has a large inventory of products. I decided to call and the salesperson Mellissa found the correct part in minutes and had it shipped to my house in less than 24 hours. It’s is nice to know that etrailer still believes in great customer service and the human element of customer service.


Hub assemblies worked great and flawlessly on my boat trailer. Will definitely recommend etrailer for any trailer related items!!


All parts arrived as expected and fit on my trailer as expected. The install video on the website was a great resource for a first time bearing packer and installer, such as myself.

After a year, the hubs and bearings are still working flawlessly. I guess I installed them correctly Excellent product!

I received both my HUBS yesterday and installed just the LH side unit for now. The LH side Hub was the one where both bearings had come apart for not keeping them "LUBED" and a worn out inner seal. I really thought I was going to have to trash my trailer. On a trip back to the house the HUB had been running on its axel shaft, but "THANK GOD NOT FOR A LONG TIME". I had a little bit of a problem getting the inner bearing to slid on the axel shaft but that was because of the old HUB had marked up the axel shaft and needed a little sanding down for it to slip on. Everything went on as planned and today I'll be taken her for another load of Top Soil. Let me tell U, etrailer has been my source for everything I've needed and the help in ordering the right stuff and prices are "EXCELLENT".


Excellent product. This assembly is a great value, I installed it on my seadoo trailer. The only thing that did not fit was the grease seal. The one that comes with the kit was too big, I had to order a smaller size to fit my spindle. I totally missed that when I ordered it. Highly recommend this product! Thanks for the great customer service.


I bought these hubs as replacements on a 1992 Coleman tent trailer. Although I purchased them a year ago, they weren't installed until a couple of months ago. My son took the trailer camping in the mountains last month, and his trip went well. I'm very happy with these hubs!


Had to get my 20lb sledge to "tap" it onto straight axle. She sits on there fine now! Cotter pins slightly too large to fit all the way through hole but those should be easy to find. Trailer people very nice but made me take the opposite side hub off and apart to get code numbers on bearings as they could not identify the hub size on my 5x8 TarterTrailer that I bought a few years ago at Home Depot. Home Depot would not help as Tarter no longer makes trailers.


I bougat a pair of trailer hubs front etrailer. The precise measurements on the bearings and seals given on the Web site made it very easy to select the correct part. During installation they fit like a glove. Shipping was prompt. I recommend etrailer for your trailer needs.


The hub kit came all pre-assembled and greased ready to go. All I had to do was clean off my spindle, put the new hub with bearings on, washer, castle nut and cotter pin and I was done. One of the easiest projects I've done and a very quality product at that!


After installation on my snowmobile trailer, and use for 2 seasons now, the product is still going strong. Good build quality and excellent value, I expect these hubs to last the remaining life of the trailer! I will continue to do business with etrailer. Thank you!


good service. my second order I ordered the wrong size hub. talked to sam on the phone and he figured out what I needed and I reordered and got what I needed. he sent me info on how to return my wrong one and everything went good. I had recently bought a hub and bearings like this from a parts store for $59.00 and this one from e-trailer I think was xxx dollars. very good place to buy.


Kind of early to review since I just installed them and haven't actually tested the product out yet but seems ok so far, $ for hubs is a greeat price and comparing the hub I took off I can't see much difference

Just a suggestion, go ahead and throw in .20 cents worth of cotter pins to complete the set, would have paid a few dollars more not to have to run to the hardware store for a cotter pin


I have a trailer company few towns away but decided to use e trailer very happy with my experience, great selection of parts and prices will definitely recommend E trailer to anyone looking for great products at fair prices and extremely fast shipping thank you.


Although I just received them today it looks like it's what I wanted


Everything fit as expected. I wish it came with the spindle nut and washer both were damaged from prior bearing failure. Other than that they worked like a charm.


One year review? Wow! My memory is shakey from one week ago. I do recall however that the products I ordered came and performed as expected and I would recommend etrailer products to anyone.


Great price, quick delivery. Super easy install, 10 minutes with a beer. Glad I bought the pre greased ones.
You gotta really hit the dust caps hard to get them on.
Look great with my new tires and wheels.


Correct parts arrived very fast, prices are great, customer service second to none. I don't believe I'll be shopping for trailer parts anywhere else. You guys hit it out of the park! Thank you


Just replaced it yesterday. No problems. Your site and info on replacing it was spot on for someone that has never replaced one. Thanks. It would have been 5 stars but you don't provide a new outer washer. No bigy, used the old one.


Super service, good products

They are going great, thank you. Would like to buy more soon.
Don - 10/17/2017


Great price. Wrong size grease seal for my 1995 fleetwood popup. Upgraded me to 2 day shipping without charging day after I bought it. Will be a repeat customer.

  • Idler Hub for 13-Inch Trailer Wheel That Uses L44649 Bearings
    The Trailer Idler Hub Assembly # AKIHUB-545-2-2K you referenced is compatible with wheel diameters from 8-inches up to 12-inches. It is not usable with your 13s. For a similar idler hub that uses the same bearings (meaning it will fit on the same spindle as the other part) you can use one of the hubs shown on the linked page. All items shown use the same L44649 bearings, work with 13-inch wheels and have the same 5-on-4-1/2-inch wheel bolt pattern as the part you referenced. All of these...

  • Trailer Hub that Can Fit on 2,000 lb Axle with 5 on 4-1/2 inch Bolt Pattern
    Are you sure the diameter of the spindle is 1.25 inches where both bearings ride? That's not typical for a 2,000 lb axle but if instead the diameter is 1.06 inch then you could use the hub part # AKIHUB-545-2-2K which has the 5 on 4-1/2 bolt pattern you need as well. If instead the spindle measures .99 instead you'd want the part # AKIHUB-545-2-1K.

  • Troubleshooting Replacement Hubs Not Fitting Over Detail K2 Utility Trailer
    I believe the Trailer Idler Hub Assembly # AKIHUB-545-2-2K is the correct hub for your Detail K2 Utility Trailer, however it looks like the problem is that the inner cones from the old bearings are stuck to the spindle. Most likely the hub wasn't lubricated quite enough, or they got too hot for some reason, and the excess heat caused these components to lodge into the spindle. When you removed the hub these pieces stayed behind. This is specifically the cone/lip you see on the outer portion...

    If the axle of your trailer has a 2,000 lb capacity there is a great chance the part # AKIHUB-545-2-2K will fit and work well as a replacement since this hub fits most axles of the capacity. What you can do to be sure is to pull the bearings out of the hub and get the numbers that are stamped on them. If they are both L44649 this hub will fit. The other way to tell is to measure the diameter of the spindle where the bearing rides. If both bearing surfaces measure 1.06 inch on the spindle...

  • Replacement Idler Hubs for 4 x 7 Tarter Utility Trailer
    A 2000 lb axle uses a straight spindle, with both the inner and outer bearing being the same size. The hubs needed will depend on the number of lugs your current hubs have and which inner/outer wheel bearings are used. I'll give you a run-down on the possibilities below. If you have a 4 lug wheels, and a L44643 inner and outer bearing, you'd use # AKIHUB-440-2-1K for 5 lug wheels, use # AKIHUB-545-2-1K. Both fit wheels from 8 to 12 inches.

  • Replacement Hubs for Axle Spindle with 1.06 Inch Diameter
    The best way to match hubs to an axle/spindle is going to be by finding a hub with the same size bearings as the ones that you removed; you can usually find numbers stamped on the backs of the bearings that designate their size. The Trailer Idler Hub # AKIHUB-440-2-1K you were looking at uses an # L44643 inner and outer bearing, which has a 1.00" I.D., so it's going to be just a tad too small, but we do have a solution for you.
