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"

CE Smith Trailer Idler Hub Assembly w/ Case for 3.5K Axles - 5 on 4-1/2 - Galvanized - Pre-Greased - CE13515

Average Customer Rating:  4.6 out of 5 stars   (52 Customer Reviews)

Pre-greased, marine-grade hub is built for trailer idler axles. Fits 3.5K axles with #84 spindles. Inner bearing (L68149) and race, outer bearing (L44649) and race, grease seal, cap, lug nuts, and cotter pin included. For 13" to 15" wheels.


The parts were shipped quickly and packaged well. There were no instructions included with the package and when I assembled all of the parts I did not realize that the inner and outer bearing races were already pressed into place in the hub that I bought. I attempted to install the bearings in the new wheel hub and when I went to put it on the trailer it would not fit. I kept thinking I was doing something wrong and ended up ruining two grease seals before I figured out that the bearing race was already pressed into place and was not needed. That is entirely my error ( I am not a mechanic…) but it would’ve been nice if it was indicated somehow that the bearing race is already installed in the hubs I bought from etrailer and that the ones that shipped with the hub package are extras for another application.


Well greased when it was received and performs well quick and easy installation. I added the bearing buddys on the front I don’t want any problems


Very good quality, value and design. I like the pregreased idea. One installation recomendation I have is to install and hold the large washer in place on the outside bearing as you slide the idler hub onto the axle. That will help keep the bearing in place and prevent grease from oozing out as you push the hub assembly on the axle.


Worked great for my change in bolt pattern on my trailer project.


I am sure this is an OK product, but when a product says Made in USA, the customer should expect the product to be Made 100% in the USA. The CE Smith sticker on the box states Made In China. The bearings inside this hub state CHINA. I can find nothing but websites that state this is Made in the USA. The better statement could be assembled proudly in the USA using parts from China.

The hub is made in the USA, but other components, like the bearings, are sourced globally.

I open the box which look in good shape pickup plastic box and open hub and lug nuts pin dust cap look went to check second hub box the top was busted and just fell off the hub was there but no package of lug nuts pin or dust cap do not know if hub is ok it looks like parts are there I called they said they would see about sending a new one

Sorry to hear about this. I see in your account that we have already shipped out a replacement.

Item as advertised good quality prompt shipping


Outstanding service and phenomenaldelivery time! The CE Smith hub kit is excellent and fit perfectly.


Ordering was easy!! The kit arrived already assembled and greased. I pulled it out of the wrapper and slid it onto the axle! Super easy and a great product!!


Working great snow trailer so made trip from PA to upper Michigan last year getting ready to head out again still doing well.


I couldn’t be happier, easy to install, and one year in working like new. We make tons of lake trips every year and holding up great, so far fresh water only!


Perfect fit. Installed bearing buddies and loaded them up, seals don't leak.


Products and company representatives are outstanding!


Great product!


Product is nice. I am disappoint in the stud length. After going through the galvanized hub there is slightly over 1” exposed. Solves my hub and bearing issue but my rims still do not fit. I still need longer studs.


Great buy and perfectly suited for a saltwater trailer. Pre-greased for easy installation.


Perfect fit, fast shipping and a fair p rice.


A well packaged and prepared assembly.


delivered in very good time customer service very good found the right part i neededI will continue to order from them when I need some thing else


On time and exactly what I ordered.


ordered hub kits for my boat trailer and products installed and worked as intended. Only problem was kits were not in stock and had to be ordered so that's reason for 4 stars but no worries I wasn't in a big rush. Good thing is etrailer kept me updated with emails and packages arrived when they said they would.


Perfect replacement hubs for my 30 year old boat trailer. Each hub comes in a handy plastic carrying case. I threw away the cases but I may buy another hub to keep in case of a roadside emergency on long trips. The case would make that a no-brainer.


Very easy to install. Be sure to save your existing spindle nut and washer.


Great product bought it to replace a seized drum brake hub for my Ezloader boat trailer , Danielle was really helpful on the phone for choosing the right hub.
Choose a galvanized hub which is better for saltwater
Fits perfectly


This hub worked out perfect for me, could not be happier.. Hub came fully assembled and pre greased in a plastic carrying case, ..I needed to use it right away but outstanding if you kept as a backup for an emergency,everything included except spindle nut and washer,

  • Spare Hub for Boat Trailer with Bearing Dimensions of 1-3/8 inch and 1-1/16 inch
    Based on your bearing dimensions you do have a 3,500 lb axle. The CE Smith Trailer Idler Hub Assembly w/ Case for 3.5K Axles - 5 on 4-1/2 - Galvanized - Pre-Greased # CE13515 that you referenced would be a really great option as it has the correct wheel bolt pattern as well as comes pre-greased, comes with a carrying case, and is galvanized to help fight corrosion which is really important for boat trailers like yours.

  • What Type of Grease is Recommended with CE Smith Trailer Idler Hub Assembly # CE13515
    LMX red grease like the # L11390 is what the CE Smith Trailer Idler Hub Assembly # CE13515 typically comes with and is the best all-around grease for trailer hubs so it's what I recommend. This will also be compatible with non-red grease if you were to find that your hub didn't have that color.

  • Availability Of Pre-Greased and Assembled 3500lb Idler Hub with 5 on 4-1/2 Bolt Pattern
    I have another option for you, but we do not offer the Trailer Hub for 3,500-lb Axles - 5 on 4-1/2 # 84545BX you were looking at pre-greased and assembled. The reason for this is the pre-greased and assembled hubs come that way from the manufacturer and that is not something Dexter offers. Instead I recommend the CE Smith Trailer Idler Hub Assembly w/ Case for 3.5K Axles - 5 on 4-1/2 - Galvanized - Pre-Greased # CE13515 which is the exact same hub as the Dexter option, but comes pre-greased...

Bearing Buddies are perfect for keeping the hubs greased and preventing water from seeping in which could cause issues issues down the road.

  • Determining Which Idler Hub Assemblies Will Replace Hub and Drum Assemblies On 19' Boat Trailer

  • What Hub do You Recommend for My 2005 Karavan BW-2350-74-ST Boat Trailer?
    From my research on your 2005 Karavan model BW-2350-74-st, you most likely have a 3500 pound axle on your boat trailer.

  • Replacement Bearing Set for Freedom Axle 45264 3500 lb Idler Hub
    If you're just needing replacement bearings, races and grease seals, you'll need the following per hub: • # L44649 Outer Bearing • # L68149 Inner Bearing • # L44610 Outer Race • # L68111 Inner Race • # 168255TB Grease Seal If you're wanting to replace the entire hub, you'd use # CE13515 for a galvanized hub or # CE13511 for black powder coated.

  • Replacement Hub for 2005 Eagle Boat Trailer
    In order to determine which hubs you're going to need as a replacement you will need to pull the hubs to see what bearings will fit on your spindle; the bolt pattern is only part of the equation, but still helpful to know. To accomplish this you can either check the numbers that are stamped on the backs of the existing bearings, or measure the spindles where the bearings sit using a digital calipers like the # PTW80157. The Dexter 10" Hub-and-Rotor # K08-435-05 is designed for use with...

    Thanks for all of the information! The products you were looking at are all compatible. Starting with the Timbren Axle-Less Suspension I would go ahead and use the # A35RD545 as it has the 3500lb rating which will be perfect for your intended trailer weight, and already includes the 5 on 4-1/2" bolt pattern hubs that you were wanting. The # ASR3500S04 is the exact same spindle just without hubs, and would work perfectly with the # CE13515 you mentioned, but there is not really much of...
