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 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. 774400

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. 433323

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. 377648

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. 371170

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. 347098

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 etrailer.com 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! 292438

Tires and wheels are holding up well, very satisfied with my purchase. Will buy again from eTrailer and also recommend to my friends.

  • 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...

  • Recommending a Hub Assembly for a 4 x 8 Trailer
    Thank you for taking the time to make all those measurements, it is a big help. Based on the info you provided, you will need the Trailer Idler Hub Assembly for 2,000-lb Axles # AKIHUB-545-2-G-1K. This assembly has a galvanized finish and can fit 8 inch to 12 inch wheels to accommodate your 4 x 8 trailer.

  • Trailer Spindle and Hub That Uses Grease Seal 12407 and Bearings L44643
    Based on what you mentioned the correct hub you need is the # AKIHUB-545-2-G-1K as it has same bearing, seal, and bolt pattern info. The spindle you need is a BT8 like the part # TRU97FR which is for a square application.

  • 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.
