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"

We install these hubs on our trailers for years and they have worked well without any problems.


Over all it is great but beware using the rubber caps for easy lube axles as they are not water tight.


Knowledgeable sales person, quick shipping and product worked as it should

Great. Easy replacement, perfect fit
Hershel - 10/15/2022


One year later, still happy with my hubs. Great price, easy installation for a first-timer. etrailer has outstanding instructions and support.


The hubs I ordered were a exact match. They worked out very well. Highly recommend!


Excellent service. Quick response to my questions


They worked well


The product was fine, other than the fact that the packaging was poorly prepared for a long ride with, UPS. Upon arrival there were two black boxes, taped together with no extra tape holding the ends. One box came open and lost all its contents before arriving to me!
Again, good product but poor packaging.
I was not able to attach the pictures, did that through the email option.

Customer Service will reach out to you.

You guys are awesome!!! Thank You.


Great service looks to be well made. Customer service was very helpful .


Products arrived as stated, however when the package as opened, there were 4 of 5 lugnuts, and one was an un-threaded standard nut. Although there was a QC signature on the package, QC was not done here. Contacted customer service and they sent out the replacement lug nut same day, got it 4 days later. Overall, very satisfied.


Trailer hub kit fit well.


Needed a nut washer.


Excellent service and products.




Packaged very nice, great product.




Great product

  • Which etrailer Trailer Hub with 5 on 4-1/2 inch Bolt Pattern Fits 1-1/16 inch Diameter Spindle
    The big difference between those two part numbers is the spindle size they are designed to fit. The part # AKIHUB-545-2-LF-2K that you referenced is the correct fit for your spindle since you have a 1-1/16 inch diameter spindle whereas the # AKIHUB-545-2-LF-1K is the correct fit for spindles that are 1 inch in diameter.

  • Parts Needed to Go From a 4-Bolt Hub to a 5-Bolt Hub on a Dexter 1,800 lb. Axle
    For your Dexter axle you will use either the Trailer Idler Hub Assembly # AKIHUB-545-2-LF-2K (for bearing size L44649) or the Trailer Idler Hub Assembly # AKIHUB-545-2-LF-1K (for bearing size L44643). You would just want to pull off your current hub and check which bearing you have. I have linked our selection of 13" wheels and tires that will fit either of the above hub assemblies.

  • Will Trailer Idler Hub Assembly # AKIHUB-545-2-LF-2K Fit 2,200 lb Axle
    Yes, the trailer hub part # AKIHUB-545-2-LF-2K that you referenced will work on a 2,200 lb axle as the bearings are the same between the two axle capacities.

  • Replacement Hub for 2022 ShoreLandr Boat Trailer
    Thank you for providing that information. According to ShoreLandr your current hub uses # L44649 inner and outer bearings. That means you can use the Trailer Idler Hub Assembly for 2K Axles - 13" to 15" Wheels - 5 on 4-1/2 - Pre-Greased # AKIHUB-545-2-LF-2K. However, it does look like they use a different seal with an inner diameter of 1.063". I recommend measuring your current grease seal to verify this information. If that is the case, you can still use this hub but you will need to...

  • Idler Hub for 13-Inch Trailer Wheel That Uses L44649 Bearings
    The Trailer Idler Hub Assembly # AKIHUB-545-2-2K you referenced is compatible with wheel diameters from 8-inches up to 12-inches. It is not usable with your 13s. For a similar idler hub that uses the same bearings (meaning it will fit on the same spindle as the other part) you can use one of the hubs shown on the linked page. All items shown use the same L44649 bearings, work with 13-inch wheels and have the same 5-on-4-1/2-inch wheel bolt pattern as the part you referenced. All of these...

  • Recommended Hubs for Small Trailer with 5 on 4-1/2 Bolt Pattern
    Since you provided the bolt pattern and bearing numbers we won't be needing the pictures. The hub assembly I suggest is the idler hubs # AKIHUB-545-2-LFEZ-2K. These are rated for 2,000 pounds and include the bearings, races, seal, grease cap, and lug nuts. For the same kit for standard spindles instead of the E-Z Lube use # AKIHUB-545-2-LF-2K.

  • Grease Seal Inner Diameter that Comes with Trailer Hub # AKIHUB-545-2-LF-2K
    I wish we offered a grease seal that has the correct inner diameter for your spindle and would fit the hub you referenced but nothing we offer matches that. You seem to have a spindle with the bearing surfaces of a BTR (1.06 inch) and the grease seal dimensions of a BT8 spindle (1.25 inch.) I'd recommend using a caliper like part # PTW80157 to measure the spindle where the seals and bearings ride to confirm this.

  • Spindle Nut for Use with Trailer Hub # AKIHUB-545-2-LF-2K
    For a spindle nut to use with the hub # AKIHUB-545-2-LF-2K that you referenced the part # 165686 would be a great replacement. You'd also need a cotter pin if you didn't have one as well with # 165649.

  • How To Measure Bearings For A 55 Chevy Spindle
    When it comes to finding replacement hub and drums on your trailer we will first need to know what your current inner and outer bearing numbers are on your current 55 Chevy Spindle. Most bearings have engraved numbers on them. You will have to give them a hot water soap bath. If you're unable to see the number you can taking measurements of the bearings with a digital caliper # PTW80157.

  • What Spindle Does Trailer Hub # AKIHUB-545-2-LF-2K Fit
    The hubs you have part # AKIHUB-545-2-LF-2K need to fit a BTR spindle like the # TRU44FR. Sounds like you have the STUB style of spindle which is shorter like you have found. To pick out an axle I'd need to know the length of your current one from hub face to hub face and from spring seat center to center.

  • Recommended Replacements for Dexter 8-257 Trailer Hubs
    An 8-257 hub is a 5 on 4-1/2 hub for 2,000 pound axles. They fit onto a BTR spindle which uses # L44649 for both the inner and outer bearings which have an inner diameter of 1.063 inches. If any of this doesn't match what you have let me know. If you just need the idler hubs and not the hub and drum assemblies we have # AKIHUB-545-2-LFEZ-2K that are for E-Z Lube spindles. Or use # AKIHUB-545-2-LF-2K for standard spindles. If your spindles have a zerk fitting on the end of them then...

  • How to Determine Correct Replacement Hub for Coleman Pop-Up Camper
    I can absolutely understand not wanting to take your hub apart to find the right replacement hub, but unfortunately that is the only option as the numbers you referenced are not any type of indicator of a replacement. So, to determine the correct hub you will need to take apart your current hub assembly and look at the bearings; wipe away the grease and you should be able to see the part number stamped directly on them. If you are unable to find them, you need to use Digital Caliper #...

  • Looking for 5 on 4-3/4 Inch Bolt Pattern Idler Hub Compatible with L44649 Inner and Outer Bearings
    The L44649 bearing is compatible with a 1.062 inch (1-1/16 inch) spindle which is used on 2000, 2200, 2500 and 2700 lb axles. A 5 on 4-3/4 inch bolt pattern hub is found on hubs compatible with a 3500 lb axle, and uses different bearings (L68149 inner and L44649 outer), so we unfortunately don't offer a hub with that bolt pattern that's compatible with your current spindles.

In order to make sure you choose the right hub assembly you are still going to need to look at your bearings and identify them.

  • What Is The Max Wheel Size For a 7 Inch Diameter Hub/Drum
    I do have an option for you but the largest wheel you can use with a 7" diameter hub/drum has a 12" diameter. The reason for this is that there is not enough surface area on the hub/drum to support that large of a wheel therefore I cannot recommend you use a 15" diameter wheel on a 7" diameter hub/drum. In order to use a 15" diameter wheel you have two options. You can either remove the brakes and use an idler hub like the Trailer Idler Hub Assembly part # AKIHUB-545-2-LF-2K or you can...

  • Should I Stay With 13" Wheels Or Upgrade To 14 Wheels?
    I will start by sating that the wheels/tires on the trailer you are looking at do look kind of undersized. So you definitely can stay with a 13" set up like the Kenda Karrier ST185/80R13 Radial Trailer Tire - Load Range D # AM10208 and Dexstar Steel Mini Mod Trailer Wheel - 13" x 4-1/2" Rim - 4 on 4 # AM20242, which will give you 1,660 pounds of capacity (the wheel is rated lower than the tire in this case).

  • Can a 1-1/16 Inch Trailer Axle Spindle Handle Speeds of 75 Miles Per Hour
    Spindles typically do not have a speed rating. Traditionally, the component that limits the trailer speed is the tire. My contact at our spindle manufacturer confirmed that the spindle will perform well when the tire speed is complied with. I also recommend servicing your trailer often if you are driving at speeds upward of 75 mph. You will want to ensure the bearings are properly lubricated and red grease, like # L11390, will work well. I've attached a help article on trailer maintenance...

The L44649 inner/outer bearings, L44610 races, 10-9 grease seal, dust caps for standard or EZ lube spindles and lug nuts are included.
