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 bought an older used boat and trailer. Checked the hun seals which had bee leainfg and saw some pitting on bearings. Bougth these new hubs and bearings. Everything fit perfectly and I we done in less than a hour. thankyou etrailer for coming through for me AGAIN!


The wheel bearings on my utility trailer gave out and the local Les Schwab wanted an arm and a leg to replace them. They also noted the tires were at the local tread limit and needed to be replaced. So I went searching for lower cost alternatives.

I found on a google search and was impressed by their selection, low pricing and expert help on their website. I ended up ordering two Kenda 5.30-12 Bias Trailer Tire with 12" Galvanized Wheel - 5 on 4-1/2 - Load Range C and two Trailer Idler Hub Assembly for 2,000-lb Axles - 5 on 4-1/2 - Galvanized from etrailer, and also a set of Reese Towpower 74177 Wheel Bearing Protectors from Amazon. My total cost was LESS THAN the price Les Swhwab quoted me for bearing replacements for the two wheels.

They are all on my trailer and and look great. I am really impressed by the quality of parts from etrailer and also their great pricing. Give them a try!

Tires and wheels are holding up well, very satisfied with my purchase. Will buy again from eTrailer and also recommend to my friends.
Mike J - 10/26/2017


I purchased 2 galvanized wheels and 2 galvanized hubs. The box they shipped the items in was sealed well with staples and was robust, but the items weren't separate well at all. Whomever packaged the order placed a few pieces of packing paper inside. All the items were tossed around and dinged up. The threaded wheel lugs on the hub were dented and needed to be filed and thread chased. Other than that, the products seem nice, but time will tell.


So, I've have a lot of lesson learnt in the rebuilding of my Boston Whaler trailer, most importantly, measure twice and order once, not the other way around! etrailer has been great at helping me get the correct parts for the project. Finally finished - Many thanks!


Do NOT be in a rush to receive the correct product. I ordered this hub on 12-2-2021. Received the order on 12-7-2021, not too bad. However, the hub I received was a 4 bolt and not a 5 on 4 1/2. Called etrailer, sent them pics to prove and verify I received wrong item. I was told to send wrong one back with a prepaid shipping label. Today (12-17-2021) the correct one (I hope) arrived. Took so long to receive it that I used a different hub for now. Hopefully when I use this one it works properly. 15 days from order date to receive what appears to be the correct item. Not acceptable in opinion.


First and foremost, etrailer is the sh*t. Not only do they have awesome customer service and helpful info, but they also have an awesome tracking system. And the best of all, the BEST prices and deals. I couldn't find hub deals this cheap anywhere and ontop of that the quality is awesome and their galvanized. Etrailer is the best.


Wonderful hubs! Fits perfectly on the old axle and is a significant upgrade from what it replaced.


I order a cast hub the first of the week , two days later a reply was sent, received your order waiting for a shipment to come from Dexter. E-trailer rep said they had a galvanized hub the correct size in stock they could sent right away if I preferred. I said to send the AKIHUB-545-2-G-1K hub. Received in three days even with Covid 19 problem we have today. Good communications, hub fit great.
Thanks E-trailer. Kenneth W.


Fast shipping.Came the day they said it would. Fits perfectly and works great.


Exactly as pictured! The only thing better than the product is the customer service! Shipped well on time and shipped in a quality box. etrailer is THE place to go for what you need. Very helpful and are now on my "go to" list!

I really havent had much use out of them yet but did get everything put on without any problems. Appreciate your concern.
John M - 09/01/2018


Excellent service & fast delivery! Finish my little project!


Ordered two wheels with tires and two hubs. Everything arrived just as described. Can't beat the price, and free shipping too! Everything fit on the trailer perfectly and is ready to go.


Everything needed to replace a hub except the grease and a new cotter pin. High quality parts and everything went together flawlessly. I was looking at a Dexter hub, but they were out of stock. The friendly sales assistant on the phone suggested this one and the price was half as much to boot! Sold! Fast shipping, friendly service.


My order arrived in the time frame projected. I was kept well informed of the shipment status. The items are very good quality and well packaged. I will order from etrailer again.


I little confusing which parts to buy but after a lot of research And your help I was fortunate to order the right parts first time. Moderately easy to assemble.


Great products!


Only needed one but I replace both glad I did easy job well worth the price wouldn't hesitate to do again



Have not had any issues.

  • Can Trailer Hub AKIHUB-545-2-G-1K Replace Hub that Used Wheel Bolts
    Aside from the wheel bolt/lug nut difference the trailer hub part # AKIHUB-545-2-G-1K is exactly the same as your current hub. This has the same 5 on 4-1/2 inch bolt pattern and uses the same bearings L44643 for inner and outer. Now what you might run into is an issue attaching your wheels to this hub. Since your old hub used wheel bolts your current wheel may not have the taper where the lug nuts would install so you might need new wheels which if you got me what size wheel you have...

  • How To Choose Correct Replacement Hubs for 2005 Wesco Boat Trailer
    In order to choose the correct replacement hubs for a trailer you'll need to know the axle capacity. The make and model of the trailer is usually irreverent as we don't have any way to look up part numbers from this. The axle capacity can be found on the axle tube itself. The smaller trailers with an axle capacity of 2,000 lbs use the Trailer Idler Hub Assembly part # AKIHUB-545-2-G-1K which has L44643 bearings. I have attached a full list of trailer hub options which you will need to...

    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.

  • 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 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. For a smaller trailer like yours, you...

    There are two different bearing combinations commonly used on 2000lb trailer axles, so determine which hub assembly will be correct for your trailer you will need to confirm which bearing combination your trailer has. The easiest way to do this is to remove one of your current hubs and look for the bearing number stamped in the face of the bearing as shown in the picture of the # L44649.
