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 recently upgraded my 43 year old small boat trailer with parts from ETRAILER. New hubs, bearings, Bearing Buddy's, wheels and tires. Natalie L spent quite a bit of time on the phone with me to figure out what I needed and when it arrived everything was perfect. This is the first time I have replaced the hubs and wheels in 43 years. Timely service, great prices and I could not be more pleased.


I have an old trailer with this type hub. Was easy to install and being prelubed was great too! Solid kit!


Great product. This was an extremely hard part to find until I learned about etrailer. I replaced the hubs on a boat trailer that has been sitting since the 80's. Hubs were greased and ready to go out of the box. Great packaging that is easy to keep one as a spare in a trailer.

Tell you more after I get but now good


Good hub with bearings,seal, and lug bolts, packed with grease, and ready to put on axle.


I received 2 new 4 lug hubs and bearing buddy. All came in great condition the lugs were in special plastic cases to protect them. I replaced but hubs with ZERO problems from the new units. Great results when I wasn't sure what would happen. Very easy to replace the old bearings and being already packed with grease made it a lot cleaner.


The hub was pregreased and ready to install. The hub arrived on time and the instructions and video where very helpful. I have pulled the trailer on several occasions and the hub preformed as promised. I am very pleased and would encourage any one looking for quality trailer parts to shop at

I am very satisfied with the hubs. I have taken the trailer on a couple of 500 mile round trips on top of a lot short fishing trips. The hubs are holding up very well.

Great Product. Great Service. It's hard to get excited about spending the day replacing bearings. But it would of been a lot worse if there were any problems with etrailer's products, and there was NOT.


Good product


Excellent and fast service. Had an issue with one factory sealed box containing the wrong part - not etrailer's fault. Erica and the etrailer team got me the correct part shipped the same day I called. And they checked the box to make sure there was not another factory mistake. Really nice people to trade with.


They are great


I have a 75 tilt trailer and wasn’t sure if I could find new ones and bam there they were CE13100. Super easy to install as well. Thanks to the people at etrailer for getting me what I ordered to me fast.


Received in a timely manner (3 days after ordering) and I couldn't be happier. This is in its own carry case and comes greased with everything you need to slide it on, put the castle nut on and drop a cotter pin in. I am planning to make a longer trip up to Northern Wisconsin this coming weekend and wanted to have a spare hub for quick repair if something went wrong.This is the ticket for a reasonable price. Hopefully I wont need it but if I do I have it ready to go.


Perfectly fit as a replacement for a boat trailer made in the 1960's.

Thanks for the feedback. We would love to see photos of your restoration work on your trailer.
-- Etrailer Expert Rachael H - 06/23/2017


Product specs were listed clearly and helped to make an easy decision. They shipped quickly and arrived with everything I ordered. Have not yet tried them on my application but if they don't work it will not be etrailer's fault. Couldn't find these hubs anywhere else and wanted to put the same thing back on the trailer that I will be taking off.


Donna was very helpful, answered all my questions and the product was well made and fit like a glove ! I will use etrailer in the future for all my trailer parts and it was a great price !


I am very satisfied with the hub and the service is great. If I ever need any more parts I will get them from etrailer.comb


Everything is great and the shipping was fast. Always good to deal with you guys. Thanks.


Excellent replacement for my old boat trailer hub


Product was shipped within hours of order being placed and arrived in in great shape. Great job done by etrailer!!


Good service,Good products


Once again customer service was of the best quality.. These people are extreamely knowledgable about their product... if you have the right information and or know for sure you know what you want you will get the right part every time

  • Measuring the Bolt Pattern of a Trailer Hub and is there a 4 on 3 Inch Bolt Pattern
    Are you measuring from one bolt to the next or from one across the hub to the opposite one? Because on a 4 on 4 hub if you measure from one to the next you will get about 2.8 inches. But if you measure across it is 4 inches like in the picture I have included. If you can tell me the inner and outer bearing numbers of the hubs you have I can make some recommendations for new hubs.

  • Replacement Hub Recommendation for Trailer with .99 inch Bearing ID Surface Dimension
    Based on the dimensions that you listed your trailer has the BT8 spindle on it. That would mean that the hub part # CE13100 that you referenced would fit it and work well.

  • Can I Leave Brake Flange On When Replacing Wheels and Tires
    It sounds like you are asking if you can switch out the tires and wheels with the brake flange still on the spindle and yes you can. However it looks like your trailer is larger and you may consider adding braking assemblies to it. If you let me know the diameter of the old braking assembly I can recommend brakes for you.

  • Equivalent Hub Assembly to CE Smith Trailer Hub Assembly # CE13100 with Lug Bolts Built In
    The equivalent hub assembly to CE Smith Trailer Hub Assembly # CE13100 that has lug bolts built in is part # CE13110. The Inner and outer bearings (L44643) and races, and grease seal are all pre-packed in this fully assembled hub with marine-grade grease.

  • Hub length of CE Smith Trailer 13110 and 13100
    I went out to the warehouse and found that the CE Smith Trailer Hub Assembly # CE13100 measured about 4-1/4" but that was with the plastic still wrapped around it. If you took the plastic away it would probably measure closed to 4-1/8". The assembly # CE13110 that you referenced is the same exact hub with the only difference being that it uses wheels studs and the part # CE13100 uses wheel bolts.

  • What is the Pilot Diameter of the CE Smith Trailer Hub Assembly # CE13100
    On the CE Smith Trailer Hub Assembly # CE13100 the base of the side that your wheel will fit measured about 2-3/4 inches as demonstrated in the attached picture. Keep in mind that this hub has a 4 on 4 inch bolt pattern and the wheel with the maximum diameter that will fit it is 12 inches. This would work perfectly with a wheel like the Aluminum HWT Series S5 Trailer Wheel # AM22318HWTB.

  • Trailer Hub Replacement Recommendation that Uses Wheel Bolts and Bearings # L44643
    The easiest solution is the part # CE13100 that you referenced as it fits as a replacement and your current wheels will work great with it. If you convert to a wheel stud style hub though you are going to have to get new wheels too as the wheels you have are designed for the wheel bolts. If that's still something you want to do let me know what tire size you have so I can pick out the correct wheel/tire combo you need.

  • Replacement Idler Hub For 1964 Holsclaw Boat Trailer With 1" Diameter Spindle
    It sounds like you are needing the CE Smith Trailer Hub Assembly # CE13100. This hub fits on a 1" spindle and has the same 4 bolt lug pattern with the threaded bolts that screw into the hub. The grease seal used has the same 1.249" inner diameter as the 47370 that you have on your current hub. It is designed to fit a BT8 Spindle # TRU94FR that is 4-1/4" long on the 1" diameter portion of the spindle.

  • Comparing CE Smith Trailer Hub Assemblies CE13100 and CE13110
    Yes, the CE Smith Trailer Hub Assemblies # CE13100 and # CE13110 will both fit on a BT8 Spindle # TRU94FR. The only difference between these 2 hubs is the Hub Assembly # CE13100 is threaded for wheel bolts and the Hub Assembly # CE13110 has wheel studs and lug nuts.

  • Recommended Grease for Repacking Bearings on CE Smith Trailer Hub Assembly # CE13100
    I spoke with my contact at CE Smith regarding the Trailer Hub Assembly # CE13100 that you reference. She stated that they use an NLGI # 2 red grease like the LubriMatic LMX Industrial Strength Grease # L11390. This will be compatible with the grease currently in the hub, but I do still recommend removing as much grease from the hubs as you can when repacking, as it's possible that the old grease may be contaminated from moisture. I have attached a great article on repacking trailer bearings...

  • How To Determine Which Spare Hub Assembly Is Correct For Spartan Sport Boat Trailer
    I would be happy to help! Unfortunately we do not have a breakdown of the specific components for your Spartan Sport Trailer, so you will need to remove one of your hub assemblies. With the hub assembly removed you will need to look on the face of both the inner and outer bearings for the bearing number. This will be stamped in the face of the bearings as shown in the included picture of the # L44649. If your bearing numbers are not readable you will need to use digital calipers # PTW80157...

  • Is a 16 Oz. Can of Grease Enough to Repack Four Wheels on a Car Trailer
    When repacking your bearings it takes very little grease, so a 14 oz. cartridge or 16 oz. can will be more than enough for your four wheels. If you aren't sure which grease to buy, I recommend the LubriMatic LMX Industrial Strength Grease # L11390. This is heavy-duty, premium grease for the toughest lubricating jobs on the biggest, heaviest equipment. It performs better under higher pressures and temperatures than standard multi-purpose grease, and it resists water better. If you don't...

The Bearing Buddy Bearing Protectors - Model 1980A w/ Auto Check - Chrome Plated # BB1980A fit 1.98 inch hub bores and work with several bearing models including the L44643.

  • Selecting New Hub to Replace Old Hub That Used Bolts
    Strictly speaking you could change your hubs by installing threaded studs that would accept lug nuts in place of the bolts that currently secure your wheels. But honestly, I would just replace the hubs since yours are fairly old at this point. The keys to selecting new hubs for your boat trailer are 1) matching up their weight rating to the axle rating; 2) matching the wheel bolt pattern, in this case 4-on-4; and 3) matching up the bearings used in the old and new hubs. A new hub has...

    For your utility trailer, I recommend the Trailer Idler Hub Assembly for 2,000-lb Axles - 5 on 4-1/2 - Galvanized # AKIHUB-545-2-G-1K since you use it for boat launching. This assembly will include all of your bearings, races, and grease seal. Your current bearing buddy caps will work with these hubs.
