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"

  • Pre-Greased Replacement 5-on-5 Hub for 3500-lb Dexter Axle
    You can confirm the weight rating of your Dexter axle by removing one hub and pulling its bearings. The included photo shows how part numbers usually appear on bearings. The specific bearings used will tell you the axle's weight rating. Just refer to the linked article that lists the bearings commonly used for various axle weight ratings. A new hub must use the same bearings as the original hub in order to fit on your spindles. A 3500-lb axle commonly uses bearings # L68149 and # L44649...

  • Recommended Timbren Axle-Less System with 5 on 5 Bolt Pattern Hubs for Overland Trailer
    I have a solution for you, and it sounds like you're looking for a Timbren system that can be used with 5 on 5 hubs that would allow you to use Jeep wheels. Unfortunately the Timbren # ASR1200S03 spindle does not have any hubs with that bolt pattern, so instead you would need to use the Timbren Heavy-Duty Axle-Less Trailer Suspension - Straight Spindle - Regular Tires - 2,000 lbs # ASR2KHDS01. If you're looking for a lifted system, the Timbren Heavy-Duty Axle-Less Trailer Suspension - 4"...

  • Trailer Axle Solution for Military Trailer with Jeep Wrangler Bolt Pattern
    For a hub that has a 5 on 5 inch bolt pattern to fit the spindles of the Timbren axle less kit part # ASR2KHDS03 which is great for applications like yours you would want the Trailer Hub part # 84550BX that you mentioned as well. This hub includes the bearings that the Timbren you referenced is designed to fit. This setup has a 4 inch lift and the hubs have the 5 on 5 inch Jeep bolt pattern.

  • Recommendation for Converting Fleetwood Neon Pop-Up to Axle-Less Suspension System with Jeep Tires
    To convert your offroad trailer to the Timbren Axle-Less Trailer Suspension System - 4" Lift Spindle w/ Brake Flange - 5,200 lbs # TASR5200S03 you will either use a crossbrace for your trailer frame at the axle location or you will add a 2 inch square tube between the assemblies (not included) into the integrated holes of the assemblies. This will give you much more ground clearance than a standard axle and will also include the suspension needed. Unfortunately that 5,200 lb Timbren...

  • Replacement Axle Spindle for Dexter P21-SLR with 76 Inch Spring Seats and 44649 and 68149 Bearings
    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. Since we can't match the spring seat to spring seat dimensions if you want to replace your axle I recommend using...

  • Trailer Hub Availability with 5 on 4-1/2 inch Bolt Pattern
    The trailer hub part # 84550BX has a 5 on 5 inch bolt pattern, for a hub that would fit the same spindle that has the 5 on 4-1/2 inch bolt pattern you would want the part # 84545BX. See review video. I attached a page that has all of the trailer rims and tires we offer that fit hubs with 5 on 4-1/2 inch bolt patterns.

  • How to Choose Correct Idler Hub Replacement for Dexter Axle 8-256 Hub
    We have a few different options for the Dexter 8-256 hub. They all use the same # L68149 inner and # L44649 bearings, you just need to verify what bolt pattern you have and then order based off of that: - 5 on 4-1/2 # 84545BX - 5 on 4-3/4" # 845475UC1 - 5 on 5" # 84550BX - 5 on 5-1/2" t # 84555UC1 To verify the bolt pattern on a hub with 5 bolts you'll measure from the center of one bolt to the far end of either bolt that's opposite of that bolt.

  • What Type Of Grease Comes With the Dexter Trailer Idler Hub Assembly 84550BX
    The Dexter Trailer Idler Hub Assembly part # 84550BX comes with a lithium complex based (NGLI #2) wheel bearing grease so as long as the grease you are wanting to use has the same base then you will be fine. The LubriMatic LMX Industrial Strength Grease part # L11390 will work well with this hub.

  • Differences Between Trailer Idler Hubs With a 5 on 5 Bolt Pattern
    Each of the trailer idler hubs with a 5 on 5" bolt pattern are a fit for 3,500 lb axles and use inner bearing # L68149 (1.378" inner diameter), outer bearing # L44649 (1.063" inner diameter), and grease seal # 58846 (1.719" inner diameter) so you will want to make sure those are the correct bearings and seal for you. You can do this by taking apart your current hub and looking at the bearing numbers, or by using Digital Caliper # 301-17068 and measure your spindle to the thousandths of...

  • What Size Spindle do Bearings L68149 and L44649 fit on
    Yes, you are going to want a spindle that has the 1.063" and 1.378" measurements. This is commonly known as a #84 spindle and can be found on our site with a few variances. For example, the TruRyde EZ Lube Spindle # TRU74FR comes with a brake mounting flange and a grease zerk fitting while the Redline Spindle # TRU64FR does not come with the flange or a zerk fitting. These fit the typical round applications but we also have one for a square application with part # TRU47FR. Any of these...

  • Replacement Hub Needed for Dexter Axle 8-256
    Your Dexter Axle hub 8-256 should use an # L68149 inner bearing and an # L44649 outer bearing which means you have a #84 spindle and you'll use one of the following hubs: 5 on 4-1/2" - part # 84545BX 5 on 4-3/4" - part # 845475UC1 5 on 5" - part # 84550BX 5 on 5-1/2" - part # 84555UC1 Just match up the bolt pattern and you'll be good to go!

  • Timbren Axle Less System Recommendation for Off Road Trailer with 5 on 5 inch Bolt Pattern
    We don't have a ton of hubs with a 5 on 5 inch bolt pattern, but if you went with a 3,500 lb Timbren system like part # ASR3500S06 you could use the part # 84556UC3 for a hub/drum or part # 84550BX for just a hub. The # ASR3500S06 has a 4 inch lift built into it so it would be great for an offroad trailer.

  • Can 17" Jeep Wheels W/ 5 on 5" Bolt Pattern Be Used On Off-Road Trailer?
    I have another option for you, but at this time we do not offer a hub with the 5 on 5" bolt pattern that is rated for 17" wheels. For example the Trailer Idler Hub Assembly for 3,500-lb Axles - 5 on 5 - Pre-Greased # 84550BX you were looking at are only rated for up to 15" wheels. The reason for this is the size of the hub will not give enough support for a 17" wheels and could cause a catastrophic failure like a wheel braking off if you hit something hard like a curb, or a bike rock while...
