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"

  • Availability of Dexter Axle Brake Assemblies K23-026-00 and K23-027-00
    We do have the regular Dexter Axle brakes and their Nev-R-Adjust equivalents. The regular (manually adjusted) brakes that you are wanting are listed as part # 23-26 for the Left Hand side and part # 23-27 for the Right Hand side. Their Nev-R-Adjust equivalents are parts # 23-468 and # 23-469 respectively. The Dexter Axle hub and drum assemblies that we have for a 3,500 lb axle use the Inner Bearing # L68149 and Outer Bearing # L44649. If you have a 5 on 4-1/2" bolt pattern then you want...

  • Replacement Hub Components for Hub 9606020
    While the # L68149 most likely corresponds to the inner bearing number of your hubs. If this is the case, you have either a 3.5k or a 4.4k axle. In order to know absolutely sure, you need to know the corresponding outer bearing number or the inner and outer diameter of the grease seal. You most likely need to wipe away the grease in order to reveal the outer bearing number. In order to accomplish this, I recommend using calipers like the 4" Carbon Fiber Digital Caliper # PTW80157.

  • Brake Mounting Flange Recommendation for Dexter 3,500 lb Axle
    Looks like you have a 3,500 lb Dexter axle without brake flanges. The correct brake flanges for that style of axle is the part # 4-35. Welding a mounting flange, possible item # 4-35, is a very precise installation. The flanges need to be installed square and concentric to the hub and drum assembly and each other. If the flange is installed incorrectly rapid brake lining wear, improper braking, trailer dog legging, bearing failure, rapid tire wear and, worst of all, weakening of the axle...

  • How to Determine the Correct Hub for My MacGregor Sailboat Trailer
    Determining the correct wheel bearings, seals or hubs for a trailer is normally done by using the existing inner and outer wheel bearing part numbers and grease seal part number. This is the only way to be sure that the correct parts are ordered. The bearing part numbers will ensure that you get the proper size and weight capacity parts for your application. When replacing the hub you will also need to be sure that you measure the wheel bolt pattern (see link) and, if the axle capacity...

  • How to Add Electric Drum Brakes to a Top Hat Econo Angle Utility Trailer
    In order to install electric drum brakes on your Top Hat Econo Angle Utility Trailer you will need braking assemblies, hub/drums, a breakaway kit, and trailer wiring. For the braking assemblies, I recommend using the Dexter Nev-R-Adjust Electric Trailer Brake Kit part # 23-468-469 because they are self-adjusting which means you don't need to make continual adjustments for even pad wear. For the hubs/drums, I recommend using the Dexter Trailer Hub and Drum Assembly part # 84546UC3 because...

  • Parts Needed to Install Trailer Brakes on a Load Rite Trailer Model UT6512
    Looks like your Load Rite trailer UT6512 has a 3,500 lb axle. Most likely it's a standard 3,500 lb trailer axle but first you have to check to see if the axle has brake mounting flanges. If you can get back to me with whether or not you have brake flanges and the brand of your axle (most likely Lippert or Dexter) I can see which kit we have that may work. Check out the link I attached to see a guide to use for adding brakes to your trailer.

  • How To Remove the Brake Drum If the Brakes Are Locked On a Reinell Boat Trailer
    A trailer hub and brake drum should be able to be removed by just sliding off the spindle after the castle nut is removed. The castle nut is located underneath the grease cap. The trailer brake should not be activated. If the brake is locked that must mean that there is pressure on that wheel cylinder keeping the brake shoes against the brake drum. I would first checked the surge coupler on your trailer to see if the master cylinder is stuck or if anything is wrong with the coupler that...

    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.

  • Is Brake Controller Needed to Stop Trailer with Electric Brakes
    We have everything you'll need to add brakes to your cargo trailer but since we don't know exactly what axles you have you'll have to check out your setup and take a few measurements to determine what exactly you'd need to install everything. We actually have a guide that walks you through this entire process as well that I have attached to this page. You will need a brake controller to activate the trailer brakes like you mentioned.

  • Parts Needed to Upgrade Trailer with 10 inch Hydraulic Brakes to 10 inch Electric Brakes
    The brake assemblies that will fit your axle and also are what I recommend is the kit part # AKEBRK-35-SA which are self adjusting and the correct size and rating. Your current drums will not need to be replaced. You can keep using your current coupler by either running a bolt through the sliding portion or welding it so that it no longer moves. To upgrade the 4-way of your trailer to a 7-way you'd want the upgrade kit part # HS381-9000 plus 10 gauge wire for the brake assemblies like...

    I reached out to Dexter and they no longer make that axle. I can confirm based on the bearing sizes you gave that you have a 3,500 lb capacity. If you determine you just want to replace the hub, I recommend the Trailer Hub and Drum Assembly for 3,500-lb Axles - 10" Diameter - 5 on 4-1/2 # 84546UC3 or # AKHD-545-35-EZ-K if you have the grease zerk integrated in the spindle.

  • Torque Specs for 3500-lb 5-on-4-1/2 Dexter Hub/Drum 84546UC3
    Torque specs for wheel lug nuts will vary depending on the diameter of the lugs, type of lug nut and the wheel's material. The linked chart details the recommended torque for many combinations. Dexter Hub/Drum # 84546UC3 has 1/2-inch studs and coned lug nuts. If used with a 15- or 16-inch steel wheel the torque range is 90-120-ft-lbs. If you need a torque wrench we offer the 3/8- and 1/2-inch dual-drive wrench part # ALL944001.

  • Correct Spindle for Hub with L44610 and L68111 Races
    The numbers that you mentioned are actually for the races that pair with the inner and outer bearings in the trailer hub. The # L44610 race is commonly used with the # L68149 inner bearing while the # L68111 race is usually paired with the # L44649 outer bearing. If this is the case then you likely have a 3,500 pound hub like the Dexter # 84546UC3 that is compatible with a #84 spindle like the TruRyde #84 Spindle, part # TRU24FR.

    Hey Ed, The Easy Grease Trailer Hub/Drum Assembly # AKHD-545-35-G-EZ-K uses grease seal # 58846 and are made by AxleTek, who is not in the U.S. The Dexter Trailer Hub & Drum Assembly # 84546UC3-EZ and # 84546UC3 uses the same grease seal part number, though the hub/drums and bearings/seals are from Dexter, which is a U.S. company.

  • Can The UFP Hub/Drums HD-1377-10 Be Resurfaced Or Will They Need Replaced?
    Based on images I could find it would appear the maximum internal diameter is 10.09. This information should be stamped on the drum itself. If you do not have any dimensions stamped on your drum they should not be turned and will just need to be replaced with the Dexter Trailer Hub and Drum Assembly # 84546UC3 that you already found. We also have this hub/drum as an EZ Lube # 84546UC3-EZ if you have the grease zerk on the end of your spindles.

  • Troubleshooting Brake Assembly on Trailer Not Applying Brakes
    First thing to check is to make sure the brake assembly ground wire is connected properly. It's very possible the ground is bad and now the brakes just aren't applying. If that's good I'd recommend checking the adjustment of the brake assemblies. Behind the assembly is a star wheel you can turn to tighten. Make sure it's tight enough to apply the brakes properly. See attached video for more info on that. 4:39 mark of the video. Could also be mechanical and you'd have to take the hub off...

  • What is the Diameter of Hub/Drum 84546UC3 for a Wheel Center Pilot Hole
    The center hub diameter for assembly # 84546UC3 is actually 2.60 inches (measured with digital calipers). On trailer wheels the center pilot hole of the wheel can be larger if the wheel is held on with lug nuts instead of the exact match for the hub. Wheels that use wheel bolts instead of lug nuts do need to match because that is how the wheel centers on the hub.
