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"

Couldnt be happier with these hubs! First one I pulled out of the box, I just verified that the races were seated, and installed after packing the bearings. One hub out of the four had a damaged bearing and seal, but it was due to packing. No biggie, was able to "coerce" the bearing and seal to look "normal". Had all four corners done and back on the road in less than 4 hours, which included uninstall of old hubs, cleaning, packing and installing new parts. Quick shipping as well. eTrailer is a great place to shop!

Pleasantly surprised that it came with bearings, seals, races, and lug nuts

I used 42655UC1 hubs on mobile home axles just required different size seal to fit spindle, great product & you guys were very helpful with helping find a hub that would fit,very pleased with this product and service.

Good ExperieneWebsite laid out good, when ordering, it showed me what products went together instead of searching to find out like which hub goes to what axle and vise versa. Fast shipping and good products. Recommend them to anyone and everyone looking for trailer parts.

  • How To Determine Axle Capacity of Trailer with 4 Lug Hubs with Brakes
    The only way to know for sure is to check your bearings. That being said, the most common 4-bolt configuration is a 4 on 4 bolt pattern, which are typically found on 2,000 lb to 2,700 lb trailer axles. The only 4 on 4 bolt pattern hub and drum assemblies we carry are for 2,200 lb axles and use # L44649 inner/outer bearings. See below. Compatible with 7 inch x 1-1/4 inch electric and hydraulic brakes # 8-173-16UC3 - Includes bearings, races, grease seal, standard grease cap and lug nuts. #...

  • Axle Weight Capacity for a Trailer Using 31.75mm and 27mm Bearings
    We do not have any hubs that take a 31.75mm inner bearing and 27mm outer bearing so we will have to figure it out another way. If you have a round axle you can measure the diameter of the axle. Typical Axle Diameters Based on Axle Capacity: 1,000-lb - 2,000-lb Axles: 1-1/2" - 1-3/4" diameter 3,500-lb Axles: 2-3/8" diameter (Can have a 3-1/2" diameter, but rarely) 6,000-lb - 7,200-lb Axles: 3" diameter 8,000-lb Axles: 3-1/2" diameter 9,000-lb Axles: 4" diameter 10,000-lb Or more axles:...

  • How are Trailer Axles Typically Identified
    Your axles should have a sticker or plate on them that identifies them with the capacity listed. Or you can use the diameter of the axle to get an idea: Typical Axle Diameters Based on Axle Capacity - 1,000-lb - 2,000-lb Axles: 1-1/2 inch - 1-3/4 inch diameter - 3,500-lb Axles: 2-3/8 inch diameter - 6,000-lb - 7,200-lb Axles: 3 inch diameter - 8,000-lb Axles: 3-1/2 inch diameter - 9,000-lb Axles: 4 inch diameter - 10,000-lb Or more axles: 5 inch diameter

  • How To Determine the GVWR of a Two Horse Trailer from the 70s
    The best option you have to determine the gross vehicle weight rating (GVWR) of your horse trailer is contact the manufacturer with your VIN. There is no way to accurately determine the gross vehicle weight rating (GVWR) of a trailer otherwise if it is not printed on the trailer itself. The term gross vehicle weight rating (GVWR) represents the most the trailer can weigh fully loaded which includes the weight of the trailer. Unfortunately, this trailer was made before VIN's became standardized...

  • Does a Trailer with Two 3,500 Pound Axles have a Gross Capacity of 7,000 Pounds
    Most likely, the trailer would be rated for 7,000 pounds gross if it has two 3,500 pound axles. But there should be a sticker or plate somewhere on the frame near the front of the trailer that lists its official capacity. Also, the trailer can only be rated as high as the lowest rated component. So for example if the coupler is only rated for 6,000 pounds and everything else is rated at 7,000 then you have to go by the 6,000 pound amount.

  • Replacement Brake Assemblies for 1997 Fleetwood Mallard
    Your 1997 Fleetwood Mallard uses standard brake assemblies and hubs. To remove the hub, you will need to remove the spindle nut and then pull the hub/drum assembly off the spindle to access the brake assembly. If the hubs have been on for a long time sometimes using a rubber mallet around the edges of the drum will help get it to move more easily. If you have 12 inch diameter brake assemblies, then you will want assembly # AKEBRK-7-SA. If you have 10 inch diameter assemblies you will...

  • Trailer Capacity for Axles with 5 Lugs
    Technically, a trailer rated for 10,000 lbs can have 5 lug hubs. They are most common on 3,500 lb axles but can be used on the rare 4,000 lb axles as well. You could have a gooseneck or 5th wheel trailer with the 10,000 lb capacity and tandem axle 5 lug axles because the tongue weight can carry the rest. If you have a triple axle trailer, it is far more likely to have that capacity. Most trailers rated for that capacity will have larger tandem axles and require a 6 on 5-1/2 inch bolt...

  • How to Determine the Weight Capacity of a Dexter Hub and Axle
    Based on your bearing dimensions, I think Dexter meant to say that the replacement hub for you is a 6-lug hub rated for a 5,200 lb axle, not that it is a 5,200 lb hub. Your axle is likely rated for 5,200 lbs, especially since the axle tubing has a 3-1/2 inch diameter. I have not heard of a hub with a 6-lug bolt pattern for a 10,000 lb axle or a 10,000 lb axle with 3-1/2 inch diameter tubing. The Dexter Hub Assembly, # 42655UC1, that you referenced is likely going to be the hub that you...

The etrailer.com Easy Grease Trailer Hub and Drum Assembly for 3.5K Axles - 10" - 6 on 5-1/2 - Pre-Greased # AKHD-655-35-EZ-K will use the inner bearing # L68149 and outer bearing # L44649, which is a good idea to verify, but should be a direct replacement for your axle.

  • Recommended Replacement Brake Assembly for Old Trailer With Wide 5 lug Brake Flange
    Although we might have a solution for you, we don't sell any brake assemblies that would be compatible with the brake mounting flange shown in your photo. You've got a few options. • You could remove the existing brake flanges if possible and replace them with modern 5 bolt. The mounting flange you need would depend on the diameter of your axle beam. • You could also replace the spindles with an axle stub that has an integrated brake flange and uses modern, easily available bearing...

  • Should I Buy a Horse Trailer with Torsion Axles or Straight Axles with Leaf Springs
    I trust regular axles with leaf spring suspension more than torsion axles only because I can see what is going on with the suspension and can fix any issues should they arise. With a torsion axle though there really isn't any maintenance you have to do so it does have its benefits. Torsion axles can also come in more configurations than straight axles in terms of where and how they mount and ride height. Going with the torsion axles wouldn't be a bad idea but I think you would be happy...

  • Parts Needed to Install a 7-Way and Brake Controller in a 2002 freightliner Sprinter
    First you will need to start with a 4-way. For that you would want the part # C59496. See installation instructions and install video I attached. That will give you a 4-way that you can then convert into a 7-way. For everything needed to convert your 4-way to a 7-way and install your brake controller you would need the part # ETBC7. I attached installation instructions and an install video for you to check out for this as well.

  • Is There Advantage to Going with Trailer Axle with More than Needed Weight Capacity
    As long as the axle has the needed capacity for the trailer there isn't an advantage to going with a heavier duty axle than needed. It's definitely better to have more axle capacity than needed, but all that really means is that the axle is not going to be the weakest link in the setup. I also attached a link to a page with all of the axles we carry. The two dimensions in the picture I attached too are what you need to pick out a replacement. Basically you need to know the spring seat...

  • Determining Weight Capacity of Square Axle Trailer
    Square axles are harder to identify weight capacity as they don't have standard diameters that match a specific capacity like round axles do. So what you can do is first check the VIN plate of the trailer up near the coupler to see if the capacity is listed there. You can also check the axle to see if there's a tag there that would have the capacity listed. Otherwise we have to pull off a hub and identify it so we can determine it's capacity. Once you have the hub off you can get me the...

  • Determining Axle Capacity for 2 inch Square Axles

  • Replacement Axle For Dexter 3500lb SLR Axle

Based on the information you provided my contact at Dexter was able to confirm that you have a 3500lb axle with a 94.5" hub face to hub face measurement and an 81" spring center to spring center measurement. For a replacement I recommend the Dexter Trailer Axle w/ Electric Brakes - E-Z Lube - 5 on 4-1/2 Bolt Pattern - 95" - 3,500 lbs # 7359765-EB which will be stick out 1/4" further on each side so you won't have any issues, but the spring seats are slightly...

  • Trailer Axle Weight Rating for 2 Inch Square Axle
    The 2x2 inch square axle is likely 3,500 lbs or less capacity. I would need more spindle dimensions or bearing numbers to assist. If you pull a hub and measure at the spindle where the bearings and seal ride using the digital caliper like # PTW80157 I may be able to give you a more specific capacity based on the spindle measurements.

  • Upgrading Underrated Axles on 31-4BH Coleman Lantern Travel Trailer
    If I'm reading you correctly, your travel trailer has a GVWR of 10K, but has two 3500 axles? If that's the case, your axles are horrifically overloaded and should be upgraded. Installing 12 inch brake assemblies (which likely wouldn't work because the available 12 inch drums would use a different bearing set than a 3500 lb axle) would provide better braking, but wouldn't fix the fact that the axles are underrated. Your best course of action would be to replace your current axles with 5200...

The spring center to spring center measurement is 74" so you would need to move the spring seats using part # TRSS238. The axle measures 89" long.
