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"

Install was easy, I just wish it came with a cotter pin. I had to run to HomeDepot.


These hubs worked great. I had to add the spindle nut washers to get good engagement between the spindle nut and cotter pin. I would definitely buy these again.


Hubs not made by dexter and not made in US. No reason to pay extra for these over other Chinese hubs. Would have returned but etrailer was slow to ship and I was leaving for a trip and couldn't wait.

It looks like you may have been sent the wrong part by mistake. I am sending this along to our customer service team to make sure that they reach out to you.


There was a problem with the initial order I received and it was promptly handled by the polite and helpful customer assistant. These parts worked great for a single bike takedown trailer.


The hub was very easy to install. The only problem I had was installing the wheel bearing hubs. It took many tries to get them on.


Ordered two hubs, only one arrived. Second tracking number says it was never picked up. Now I have to wait 8 days for an investigation before I can get a replacement part. Upgraded the shipping so I could receive and work on trailer during the holiday break. No blame, just stating what happened.


I wanted to change from four lug wheels and tires to five lug type on my boat trailer. Towed trailer,loaded with fishing gear,fuel tanks, extra motor. and batteries from central Pennsylvania to Fort Peck, Montana and back. The trip was uneventful. Other than the was GREAT!
Your new hubs made my trip successful.


Made 4 800 mile trips to date with absolutely no problems. I would buy them again


Smaller, bearing on the backside came out once I open the package

Oh my goodness! I will have our Customer Service team reach out to you.


these are great hubs. my trailer had tiny 4 bolt hubs and wheels and these fit perfect on the 1" spindles and allowed me to run a much taller tire. even comes pregreased with plenty of grease


I have ordered from e-trailer twice. Both times they provide excellent service! Parts arrived amazingly fast!! One order had a damaged part, I called and got a very nice sales rep. Parts were replaced FREE. I will deffinatly order from them again. I ordered hubs, wheel and tires, and light kit for my boat trailer. All parts are good Quality.


Hubs went on without any trouble. Only tricky part was to get the caps seated into the hub to trap the grease. Haven't used the trailer yet, but don't anticipate any problems. Shipping was awesome. I ordered with standard shipping and the box was on my porch the next afternoon.


The hub I ordered for my trailer worked perfectly!!!!!! The customer service is unreal, from fast shipping to constant checks(personal emails) to see if item had arrvied on time, truly a professional company that puts their customers above all. I never write reviews put this company definetly earned it, Thanks and I will be back!!!


I initially ordered a pair of hubs from another online retailer That I has used prior and whom had mine "in stock". They didn't. After 5 days of no shipping info, they notified me they were back ordered. I cancelled the order.

I ordered a pair of these hubs from on 6/2, George notified me on 6/3 that they shipped and I received them on 6/6. That's customer service.

Price, availability and delivery. Every online retailer should strive for this level of attention..


Put on trailer brand new again hubs bearings all good fast shipping will deal with you again thanks


Not only is the product exactly what we needed (the dust caps are a little on the lightweight side) but Matthew was extremely helpful in getting me the parts I needed to fix my trailer!


I am just starting on a restoration of a 40 plus year old motorcycle sidecar and the hub and wheel that I ordered are perfect for this project. I will try to send pictures on completion, probably a few months out.


Perfect fit. Bad old trailer bearings? Buy the complete hub!


Fit perfectly


Good product fair price. Packaged well. No missing parts.


fit perfect,
great website I easily
found what I needed,
seems well made,
the outside dust cover was hard to install (I had to fiddle with it)


high quality wheel hub


Shipping was fast and install was easy...your measurement guide was very helpful to figure out my spindle size and lug stud spacing for my wheel. Thanks


Great price, fast shipping, and customer service is professional. I will continue buying from etrailer. Thanks for your business.


absolutely the best customer service ( George) and the fastest transit times - have been using them for years - never a problem

  • Replacement Hub For A Trailer With A BT8 Spindle
    For a replacement hub that uses # L44643 bearings with a 5 on 4.5 bolt pattern you'll want the Dexter Trailer Idler Hub Assembly # 8-258BTUC1. This will come as a quantity of one so you'd need two kits to do both sides of the axles. Each kit will come with the bearings, races, seal, grease cap, wheel bolts, and lug nuts included.

  • Pre-Greased Trailer Hub for Floe Pro 100 Snowmobile Trailer
    From previous customers who have the same Floe Pro 100 trailer we have determined that the correct replacement hub would be for a 2k axle like with the part # AKIHUB-545-2-1K which is pre-greased.

  • Hub Recommendations to fit a BTR Spindle with 1.06 C and D Dimensions
    Based on the C and D dimensions you listed you have a BTR spindle. The correct idler hub with a 5 on 4-1/2 inch bolt pattern that you would need would be the Trailer Hub Assembly # 8-259-5UC1-EZ. If you needed a hub and drum assembly for your spindle you would need the Trailer Hub and Drum Assembly # 8-257-5UC3. The # 34822545BX would not work on your spindle dimensions.

  • Grease Used & Bearing Buddies For 2k Dexter Idler Hub 34822545BX
    The grease for the Dexter Trailer Idler Hub Assembly for 2,000-lb Axles # 34822545BX is a lithium grease like the Dexter Multi-Purpose Lithium Grease # DX64TR. The hub comes pre-greased so you do not need at add any more when installing. Then in regards to Bearing Buddies the correct fit for this hub is the Bearing Buddy Bearing Protectors # BB1980A.

  • Replacement Idler Hubs for 2500 lb Axle With 5 on 4-1/2 Bolt Pattern
    The 2500 lb axle uses a straight spindle which is compatible with either the L44649 or L44643 inner and outer bearings. Your existing bearings will have the reference number etched into the side of the bearing cage for easy identification. We have one 5 on 4-1/2 inch bolt pattern option for each bearing set. If you have the L44649 bearings, use the Timbren # TA88545-2 which are sold in pairs only. If you have the L44643 bearings, use the CE Smith # CE13210 which is avilable individually. Either...

  • Replacement Boat Trailer Hubs with Bearing Kit and Matching Wheels and Tires
    It sounds like you have a standard 1 inch straight spindle. Because it is for a boat trailer, I recommend replacing your hubs and bearings with a galvanized hub to reduce corrosion. My recommendation is the # AKIHUB-440-2-G-EZ-1K for a 4 on 4 inch bolt pattern. The # AKIHUB-545-2-G-EZ-1K is the fit for the 5 on 4-1/2 Inch bolt pattern. I've linked the pages to the wheel and tire combinations that will work well with this bolt pattern. You will want to find the closest size to what...

  • 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...

  • What Size Hub will Work with the 215/60-8 Trailer Tire with 8 Inch Galvanized Wheel Load Range D
    The proper size hub for the 215/60-8 bias trailer tire and wheel, # AM3H325, is going to depend on the weight capacity of the trailer you are designing. This wheel and tire combination is capable of 1,165 lbs at 70 psi, so each axle in your design would need to be rated for 2,330 lbs or less. Most likely if this is the proper capacity for your design you will be using a 2,000 lb axle and the Trailer Hub Assembly, # 34822545BX, would be the proper choice if the spindle on the axle you...

  • Replacement Idler Hubs for Utility Trailer
    Thank you for the photo of your trailer idler hub and for the details about its bearings. New hubs must use the very same bearing set in order to fit on your spindles. All 6-on-5-1/2-inch idler hubs we offer are shown on the linked page. Timken bearing 15118 does indeed have an inner bore of 1.189-inches but we offer no bearing with this same bore dimension.

  • Can Jayco Pop Up Trailer with 4 Lug Hubs be Swapped to 5 Lug Hubs
    Since you have a 4 on 4 inch bolt pattern currently that would indicate that you have a 2,000 lb axle so you could swap your current hubs pretty easily with the bolt pattern you are looking for with the part # 34822545BX that you referenced. This hub comes pre-greased and ready to install as well.

  • Where to Measure on Trailer Spindle to Pick Out Replacement Hub
    Are you sure about the inner diameters of the bearings? Since you said it's a Dexter we should have a solution unless this is a mobile home axle. Typically Dexter spindles have an inner diameter of 1.38 and an outer diameter of 1.06 where spindles ride or have inner diameter that is 1.74 and outer diameter that is 1.25 inch so it seems you might be measuring wrong place. Especially since the seal diameter of the first spindle dimension set I mentions is 1.73 inches. Check out the picture...

  • How to Determine Bearing Dimensions to Select Replacement Trailer Hub
    My bearing cross reference does not include the Bower bearing numbers BT1151 and T09074 so in order to see if we have a hub that uses compatible bearings you'll want to measure your spindles at the points C and D shown in the linked image. These are the points on the spindle where the inner and outer bearings ride. You will need a precision digital caliper, so that you can measure precisely to the nearest thousandth of an inch, such as 1.234-inches. A new hub must use tapered roller bearings...

  • What Limits the Speed of a Trailer
    What limits the speed a trailer can go is the tires. Trailer tires are only rated to go 65 miles per hour. If you are traveling fast enough that bearings in good condition begin to damage themselves the trailer tires are probably already in the process of failing. Trailer tires are built with a thicker sidewall, to handle vertical loads, that get hot enough to fail when you exceed 65 miles per hour. Going to a larger diameter wheel/tire will not give you the ability to exceed the speed...

  • Difference Between Hubs Designed For 8-10 Wheels and Hubs Designed For 13-15 Wheels
    The difference between a hub that fits a 8-10" wheel like part # 34822545BX and 13-15" wheels like part # AKIHUB-545-2-LFEZ-2K is normally the hub diameter but that is not always the case. Some hubs are designed for larger wheels because the diameter of the idler hub is larger. Some manufacturers label their hubs to only be used with certain wheel sizes. The AKIHUB-545-2-LFEZ-2K hub that fits 13-15" wheels is 6.25" compared to Trailer Idler Hub Assembly for 2,000-lb E-Z Lube Axles part...

  • Trailer Hub Assembly Must be Put Together and Packed with Grease
    The trailer hub assembly, part number, 34822545BX, comes with the race attached to the hub. The seal and bearings are not attached. Those parts must be assembled and packed with grease prior to installing the cap. I have attached a FAQ sheet for wheel bearings and two videos for your review.

  • Idler Hub Assembly for 2,000 lb Axle With 13 Inch Wheels
    We do have a solution for you, although the Dexter Trailer Idler Hub Assembly for 2,000-lb Axles # 34822545BX does require wheels be only 8" to 12". The reason for that is there is this hub does not have a large enough flange diameter in order to to provide the necessary side-to-side support for a larger 13" wheel, so it can become loose on the hub. Instead, the hub you need for your 13" wheel is the Dexter Trailer Idler Hub Assembly for 2,000-lb Axles # 8-258BTUC1. This uses the same...
