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 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.


Comments
I am sincerely sorry that the wrong hub was shipped. I will have our customer service team would reach out to you.

by:

Great hub and bearing assembly. Everything fit perfect, which made the job much more affordable and easy to complete. I highly recommend this product.




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:

I have an old trailer frame I built into a yard trailer. These hubs/bearings matched the number on the old bearings and fit just fine. I hope they last many years.




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:

Exactly what I needed to the old boat trailer on the road again.. thanks




by:

always have the parts I need, fast serv ice




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.


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

Only one problem. 1 of the 8 lug nuts is smaller than the other 7.

Still working fine.

by:

First time doing bearings. Everything went great except grease/dust caps would not go on so I got bearing buddies, no problems there.


Comments
The grease caps can be challenging to install because of their tight fit. The best bet is to apply a very thin coat of grease around the inside edge of the hub bore. Have a helper hold the cap centered over the bore. Plase a small scrap of wood over the cap and drive it into place with a hammer. The scrap of wood will prevent the cap from being damaged.

by:

Got it to me right away, and on the exact day they said. Hard to find reliability these days. Thanks




by:

This kit worked perfectly to replace the old hubs on a 1960s motorcycle carrier. If anything could have been improved upon it would be to include a cotter pin with the kit and have the new hubs come pre-painted rather than bare steel. Regardless, the kit passed it's first tests carrying perhaps 1000 pounds of excavator buckets on a busy freeway with potholes and bumps and survived several trips on a very twisty paved road with cliffs on the side dropping into the South Yuba River. The kit works! It's 'ok'!




by:

Good value. I am taking a long trip and bought this as a spare just in case.




by:

Quick and easy - exactly what I needed




by:

great product with short delivery time




by:

New axle bearing hubs and jack were back ordered. etrailer helped me change to hubs and jack that could ship immediately at no additional charge. Order arrived a day early. Very pleased. Previously ordered a new trailer hitch. Very quick delivery on that one as well. Very pleased with etrailer service and support. Will order from them again!




by:

It was a perfect fit, I liked it so much that I bought a spare, I am pretty sure the other hub will fail soon and I rather be ready with a product which is guaranteed to work.




by:

3 stars out of 5 = difficult dustcap install. Hubs and bearings as advertised - appear to be good quality. Dustcaps were a nightmare to install. Yes I tried every technique and trick under the sun known to human kind. The tollerance for fitment was ridiculously tight. Plenty of persuasion, greasing, 2x4 placement with mallet whacks - about 20 seperate attempts and they fit like a glove. Plenty of negative feedback on difficulty installing dust caps in other reviews.




by:

Easy to install, quality product. Would buy again.




by:

Hub, bearings, and race were all good and looked fantastic. Fit together perfectly. But when it came time to put on the caps they seemed a hair too big and wouldn't go on perfectly. I had to pound in a couple corners of the flange to get them to fit. Otherwise those looks good and seemed to spin real smooth once installed.




by:

Needed some hubs for a log arch I'm building. These are simple, inexpensive and reasonable quality. The plating is pretty poor; these aren't going to be really suitable for salt water immersion - but they'll work nicely in the woods behind my tractor.


Comments
The hubs are working well I used the log arch to move multiple large logs around this summer. The golf cart wheels & tires Im using shield the hubs from the rain - handy in the PNW.
Bart - 12/14/2020

Excellent product, perfect fit, replaced cheep Harbor Freight parts. Use trailer to haul my 12' boat so the hubs get wet. No problems.

  • Replacement Idler Hub Recommendation For Boat Trailer With 07100 Bearings
    To find the correct hub for your boat trailer there are a couple things you need to know. First, you said the bearings you have are 07100. In my research I found that the 07100 bearing has an inner diameter of 1.000 inch. We have a bearing that matches that dimension. It is part # L44643. If your hub uses the same inner and outer bearing the hub we offer that is a match is part # AKIHUB-440-2-1K. This is an idler hub for 2000-lb axles and it has a 4 on 4 bolt pattern. The hub comes...

  • 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...

  • 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.

  • 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.

  • 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...

    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.

The galvanized metal will be corrosion resistant, so you just need to determine your bolt pattern and...

  • 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...

  • 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.

    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.

  • 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.

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....
