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 wish it came with a new axle nut and washer, but i was able to use my originals so no big deal. good product, fit perfect

We do have the spindle nut for the one inch spindle as separate part, part # 165686
Trailer Spindle Nut 1"
. The matching washer would be part # SW1000

-- Etrailer Expert Jenny N - 05/03/2022


The parts were all the right ones and most were Dexter oem parts. The only problem I had was putting the bolts in the frame end of the spring perch. It was easier to take the spring loose from the axle, put the bolt in ,then bolt it back to the axle. I intend to buy all of my future trailer parts from etrailer.


Great experience. Only problem...the carrier delivered it to my neighbors house. Guess they can't read the address label:)


was exactly as I ordered and quick ship ping


Very good price for authentic made in the usa parts, cant beat that


Thanks for the great service. Everything was delivered on time and fit perfectly.


Etrailer makes shopping for easy, great pictures and descriptions make it easy to find the right part. This drum was an exact fit for our Dexter brake system on an older tri-axle. We replaced all 6 and they look and fit as the original.


They are a perfect replacement for the 2x12 dexter utility. You are better off going with these rather than the cheaper ones.


It was exactly what I needed. Easy to find on the internet, easy to order. The price was good and the shipping was quick and free. Thank you.


This is an awesome sight. My purchase was correct and timely. I will definitely be ordering from etrailer in the future. Excellent job.


Perfect fit! Very easy to install. Delivery was also very fast. We'll done etrailer.


great hub. Fit exactly like it should will order again if another one goes bad


Excellent service, fast ,great product


item was right the only I had trouble with was the seal after getting it in it keep popping out had to buy different one , Angie was a great help I would definitely use them again


Fit perfectly. All the parts were there all I had to was add grease. Thanks so much for the speedy and free shipping. Love you guys!!!



not many of these hubs around...looks good like the original hub....thanks...

  • Replacement Hubs for a Hudson Bros. Trailer with 5-Spoke Utility Hubs
    Dexter hub # 8-174-5UC3 uses the 5-spoke utility bolt pattern so it is uncommon just like the hub you have. If your existing hub uses inner bearing 25580 and outer bearing 15123 with a seal inner diameter of 2-1/8 inches then this hub is a likely fit. The bearing numbers and seal are key.

  • What to Inspect on Trailer Brakes, Drums, and Bearings
    Starting with the brakes if the pads on the shoes are cracked or if the wear indicators are showing then they should be replaced. If there are no wear indicators and you notice weak braking with the brakes adjusted out then they would need to be replaced. For magnets if you can see the copper windings coming through the magnets will need to be replaced. For the drums look for any discoloration, scoring, cuts, scrapes, gashes, and things like that. If present then the drums should be replaced....

  • How to Pick Out Replacement Hub for Trailers
    In order to pick out the correct hub assembly for a trailer you are going to need know a few key pieces of information. The first thing you will need to know is the bolt pattern of your hubs. This is so you get a hub that is compatible with your wheels. I attached an FAQ article on determining bolt pattern for you to check out. Next thing you will need to know is what spindle you have on your trailer. In order to do that you can either get the inner and outer bearing numbers from a hub...

  • Removing Broken Studs in Hubs on a Mobile Home Hub Assembly and Replacement Parts Information Needed
    According to my technical contact at Dexter Axle the studs on a mobile home axle are a screw in style of stud. To remove and extract the stud without damaging the existing threads for the studs would be very difficult. It is possible to drill out the studs and use a tap system, but make sure not to damage the existing stud threads on the hub. If the threads are damaged then using replacement studs would not be a realistic solution. Their recommendation would be replace the entire hub...

  • Mounting 5 Spoke # 8-174-5UC3 Trailer Hub to Rim
    Typically the hub would be dropped into the rim from the rear until it seats on the lip that runs around the inside of the rim. The rim clamps would then be put in place, and evenly tightened to secure the hub to the rim. If the hub is not seated fully against the rim, and if the clamps were unevenly tightened it would explain the oscillation or wobble you are experiencing. It is also possible that your rim is warped or bent, which would also cause the problem.

  • How To Determine if 5 Spoke Utility Hub 8-174-5UC3 would Fit Trailer Spindle
    The part # 8-174-5UC3 could fit your spindle but you have to check the bearing numbers that are in your current hub or measure the spindle where the bearings ride. The bearing numbers that you'd need would be 25580 and 15123 and the dimensions are 1.750 inch and 1.250 inch.

  • One Out of Four Trailer Hubs or Wheels Causes Tire to Rub against Trailer
    It probably isn't the drum that is the problem. It is probably the wheel. Some wheels have an offset meaning the mounting surface of the wheel is not right at the center. In this case the mounting surface would be further away from the trailer which moves the tire closer. You can determine if it is the wheel by taking it off the trailer and comparing it to one of the other wheels. To do this lie the wheels face down on the ground. Lay a flat board or yardstick across the tire on each of...

  • Replacing Wheels on a Trailer with 5 Spoke Utility Hubs and 8-14.5 Size Tires
    What you have on your trailer is called a 5 spoke utility hub, like part # 8-174-5UC3. They're pretty common on mobile homes so I'm guessing this is where your axle came from. This is also evidenced by your 8-14.5 tires since they're often on mobile homes as well. In order to replace the rims with a different bolt pattern you need to replace the hubs. Mobile home axles are often hard to find replacement parts for so there may not be anything available without replaing the entire axle....

  • What is Bolt Pattern of 5 Spoke Utility Hub 8-174-5UC3
    The hub # 8-174-5UC3 has a bolt pattern of 5 on 10-1/8" which is not a bolt pattern we have wheels for. This is because this bolt pattern is most commonly associated with mobile home wheels.

  • Standard Style of Trailer Hub To Replace Dexter 8-174 on Mobile Home Axle
    We have the part # 8-174-5UC3 which is an exact replacement for your hub, for a more standard style of hub/drum that will fit the spindle you instead would want the part # 8-201-9UC3-EZ which has the very common bolt pattern of 6 on 5-1/2 inch.

  • Would the Hub and Drum # 8-174-5UC3 Fit My Mobile Home Axle
    Typically mobile home axles use spindles that are very hard to fit hub/drums to because they are designed for one time use. To determine if the # 8-174-5UC3 would fit you would need to remove your current hubs and get some exact measurement of the spindle. Where the seal rides needs to be 2-1/8 or 2-1/4 inches in diameter. Where the inner bearing rides needs to be 1.750 inches and where the outer bearing rides needs to be 1.25 inches. If all of these measurements check out the # 8-174-5UC3...

  • How To Remove Broken Wheel Stud on the Dexter Trailer Hub & Drum Assembly # 8-174-5UC3
    On the Dexter Trailer Hub & Drum Assembly, part # 8-174-5UC3, the wheel studs are a screw-in stud. The wheel stud would be the Trailer Hub Wheel Stud, part # 25-11. This is a 9/16 inch stud that has a total length of 3 inches.

  • Type and Size of Wheel Studs Used on Dexter Hub/Drum # 8-174-5UC3
    The Dexter Hub/ Drum Assembly you referenced, part # 8-174-5UC3 uses 9/16 x 3 screw-in wheel studs, like part # 25-11. We do not offer a 1/2 x 3 screw-in wheel stud, nor do our suppliers offer one. To remove the wheel studs, you would use two lug nuts jammed together, like a reverse of the procedure shown in the video I will link you to.

  • What Bolts are Needed to Mount Dexstar Vintage Trailer Wheel # AM20501
    The Dexstar Vintage Wheel you mentioned, part # AM20501 is typically lug-centric, which means that it would mount to a hub that has wheel studs and would use lug nuts, not lug bolts. The wheel usually goes on a hub like part # 8-174-5UC3, which also uses clamps to join the hub to the rim. If for some reason your existing hubs use lug bolts, you'd need to determine the length and diameter of the bolt needed as well as the thread pitch of the bolt. Since in my experience, these hubs usually...

  • Replacement Rim Clamps and Wheel Bolts for 5 Spoke Utility Hub
    By 'blocks', I'm assuming you're speaking of rim clamps, which we sell individually as part # 15-2. The 5 spoke utility rims we offer, part # 8-174-5UC3 use wheel studs, not bolts. To determine if we carry a wheel bolt that would work for you, I'd need to know the diameter, whether the existing bolts use a fine or a coarse thread and the length of the wheel bolts currently used with your hubs. I've linked you to our selection of wheel bolts, you can compare your bolts to these or simply...

  • Dimensions of Grease Seal Included in Dexter Utility Hub Kit 8-174-5UC3
    The Dexter Utility Trailer Hub and Drum Assembly # 8-174-5UC3 includes a grease seal with an inner diameter of 2.125-inches. This is noted in the bearing/race/seal information that appears on the hub's page under the specs. The seal outer diameter, which matches the hub's bore, is 3.376-inches. Seal dimensions must be very precise and should be taken to the nearest thousandth of an inch, such as 2.125-inches, by using a precision caliper like # PTW80157.

  • Are There Different Size Wheel Clamps # 15-2
    We only carry the Redline Wheel Rim Clamp # 15-2 which is specifically made for the Dexter Axle Hub and Drum Assembly # 8-174-5UC3. I suppose if you have different hub and drum assemblies then it is possible that they would use different clamps but that would depend on their design. Do your axles have the same weight rating or are they completely different? If this is the case then you really need to change them out so that they match. If they are different weight ratings then that means...
