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"

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




by:

High quality stuff, really impressed




by:

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!




by:

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.




by:

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.




by:

Product as expected, delivery sooner than expected, overall very good. Replaced old hubs on moblie home axles. Very easy to do. Great service.




by:

PACKING IN BOX WAS A LITTLE LITE BUT PARTS WERE OK




by:

Always my go to for trailer parts.

Great service and fast shipping - Ricky was a big help making sure that everything fit together - thanks a lot!

  • Can I Guess or Estimate Axle Weight Capacity By Number of Lug Nuts
    I do have a few easier options for you to determine the weight capacity of an axle other than using the bolt pattern or the number of lug nuts. The problem with using the bolt pattern to tell the axle capacity is that an axle may have the a bolt pattern that could be more than one weight capacity. The easiest would be to look on the trailer VIN plate or sticker that lists the VIN number. The weight rating of the axle should be listed on that same plate or sticker. Also, the axle could...

  • How to Identify the Axle Manufacturer on a 1991 International 18 Foot Trailer
    To determine the manufacturer of your axle you will need to look on the axle itself to see if there is a plate or sticker that would indicate the manufacturer or a part number. The other way is to contact the International dealer and give them the vehicle identification number (VIN) number of the trailer to see if they can determine the brand of axle you would have. If you need to determine the weight capacity of the axle that can be done by measuring the diameter of the axle. A 3,500-lb....

  • Comparing Leaf Spring Axles, Torsion Axles, Dexter and Hayes/AL-KO
    I personally would not have any reservations about using a torsion axle. Dexter is a leader in the industry but Hayes/AL-KO are quality as well. It seems to be easier to get parts for Dexter axles and they tend to cost less. On a torsion axle you will want to be cautious not to overload it (of course this goes with leaf spring axles too). The suspension components on leaf spring axles are easier to replace as well but a torsion axle is going to give you good performance provided you keep...

  • How to Determine the Axle Capacity of Axles on a 1977 Dilly Tandem Axle Trailer
    I can tell you with relatively high accuracy what the axle capacities probably are based on the inner and out bearing numbers. If you can tell me what the numbers are on the bearings are by pulling a hub I can give you a more definitive answer. A 5 on 4-1/2 hub can be found on everything from 2,000 to 3,500 pound axles so know the bearing numbers is important. I have included a link to a video that will help you with this project.

  • Determining Axle Weight Capacity of 3 inch Axles
    Typically axles with a 3 inch diameter have a range of weight capacity ranging from 5,200 to 7,200 pounds. This is the weight capacity of each axle. Therefore, you camper trailer axles could have a combined weight capacity ranging from 10,400 to 14,400 pounds. Please keep in mind that this is an approximate weight axle range and your specific trailer axles may be different, especially considering the age of your trailer. I have also included some helpful articles that might of beneficial...

  • Boat Trailer Tires are Wearing On the Inside Tread
    Generally when tires bow out at the bottom, in at the top, that indicates that the trailer is overloaded. If you are within the 2,000 pound capacity though this should not be happening. If the axle was ever flipped upside down, like to gain more height, that can cause this same issue. Axles should not be flipped because they have a bow in them. A flipped axle will have the bow facing the wrong way and it diminishes the capacity of the axle. Also, worn suspension components can cause...

  • Determining Corsley 6 x 20 Flat Bed Trailer Axle Rating
    Typically, the axle diameter will provide a clue to the capacity. I am assuming you have a tandem axle trailer. If the axles are 3 inches in diameter, chances are you have 6,000 to 7,200 lb axles. The fact that you have an 8 lug hub tends to further confirm this, but if you can provide the reference numbers from your bearings, I can definitively confirm it.

  • How to Determine The Weight Capacity of a 3 inch Diameter Axle
    Three inch diameter axles could have a weight capacity as low as 3500 lbs and as high as 7200 lbs. For your situation the best way to determine your axle weight capacity is by using the part numbers of the inner and outer bearings in the hub. I attached a photo that shows you where you can locate the part number on your bearings. With this information we can give you a more accurate weight capacity.

  • Axle Placement When Building A Three Axle Trailer
    In order to calculate where the axles would go on your trailer, there are several things that need to be taken into consideration. You will have to mock up the trailer with the suspension and axles to get the weights needed to determine where the axles need to be positioned. I have attached a photo that shows you the formulas needed to determine the correct position of the axles. To help you determine what components you will need, I have linked you to a help article for trailer suspension,...

  • Replacement Hub Recommendation for a Calkins Boat Trailer
    The bolt pattern is helpful information for picking out the correct replacement hub, but you need more info. You will want to remove your current hub to get the bearing numbers off of the bearings in your hub. With that info I can help you pick out the correct hubs. If you cannot see the part numbers on the bearings or grease seal, then you can take a few measurements on your spindles. I recommend using a precise measuring tool such as a dial caliper because these measurements will need...

  • How to Determine the Weight Capacity of a 5x8 Tilt Trailer
    Probably nothing too crazy, but in order to determine what the weight capacity would be for the 5x8 trailer you are considering you will need to contact the manufacturer. It might also be listed in the owners manual that is included with the trailer. Without knowing any information about the trailer like brand or part number there's really no way I could supply you with that information.

  • Boat Trailer Tires Showing Uneven Wear and Blowing Out on1995 Skeeter Trailer
    There are several possibilities for the tire wear and blowouts you're having with your 1995 Skeeter boat trailer. When a tire wears more on the inside edge than the outside edge this can indicate that the suspension (and axle) are overloaded. If the axle is bent (either from being overloaded or from damage) this too could cause the uneven wear. Since the trailer is about 20 years old it is entirely possible that suspension components could simply be worn out and are no longer maintaining...

  • How to Determine Unknown Capacity of Axle
    From what you've described, it sounds like what you have might be a Torflex torsion camper axle, likely a 6K axle that's been de-rated to 5200 lbs by the spring seat location. Be aware, this is just an educated guess on my part, your actual capacity might be lower. Without knowing the exact reference numbers from the bearings, this is about as close as I can get you. Closely examine your axles, there might be an ID plate on them listing the manufacturer and a serial number. With that information,...

  • Can Axles be Added to Trailers to Increase the Trailers' Capacities
    Possibly, but there are other factors that give a trailer its capacity. The axles are the main thing but the suspension, wheels and tires, and the actual construction and frame of the trailer. Adding another axle would increase the capacity but by how much would be hard to figure out unless the manufacturer can tell you just what the frame is rated for. A lot of travel trailers will have a gross weight that exceeds the axle(s) capacity. The reason, they say, is because the tow vehicle...

  • Add an Axle to a Boat Trailer to Increase Capacity or Replace Trailer Recommendation
    Honestly your best option will be to replace the trailer. Trying to upgrade a trailer to a higher overall capacity is pretty difficult and it can never be verified if you did actually upgrade the trailers capacity. While axle capacity is a huge factor in determining the overall capacity of a trailer you also have to figure in the weight the trailer frame and coupler was rated to carry. Since that information can be hard to determine a much easier option that will give you some peace of...

  • Troubleshooting a Torsion Axle Trailer that is Rubbing the Fenders
    If your tires are rubbing the fenders of your trailer that has 6,000 lb torsion axles it would seem that your trailer is overloaded. I would check to make sure you aren't overloading your trailer's capacities. Or it could be that you don't have proper trailer fender clearance and would need to raise the fenders on your trailer.

  • Axle Capacity for a 2-3/4 inch Diameter Trailer Axle
    Based on the 8-3/4 inch circumference you listed (and a little algebra), I was able to determine that your axle diameter is 2-3/4 inches. Which is an interesting size considering most 2-3/8 inch axles are 3,500 capacity axles and most 3 inch axles are 6k to 7k capacity. 2-3/4 inch diameter axles aren't standard size axles. I would err on the side of caution and say they are most likely around 3,500 lb capacities.

  • How To Determine Weight Capacity Of Trailer
    We have no way of knowing the weight capacity of the trailer frame you are working with unless you are able to provide some specific information. You will have to pull the bearings and seals and use a precision instrument like a digital caliper to know what size spindle you have on your trailer. If you cannot read the numbers on the bearings you can use the caliper to measure the spindle as shown in the attached drawing. Once you get those measurements, let me know and I will be happy...

  • How to Find Axle Capacity by the Diameter of a Trailer Axle
    First you should know that mobile home axles are designed for one time use only even though people do use them to make trailers. I bring this up because the fact that they are designed for one time use means that replacement parts are hard to come by. With that said single axle trailers come in all sorts of capacities. What matters is the axle capacity. To determine the capacity there are a couple of things I can look at. First you can measure the axle diameter. Usually, but not always,...

  • How to Find Weight Capacity on 2-1/4 x 3-Inch Boat Trailer Axle
    Axles usually have a sticker or plate attached that indicates weight rating. Axle dimensions can provide a general clue about capacity but are not always a reliable way to determine exactly how much weight the axle can handle. As examples, a 2-3/8-inch diameter round axle is typically rated for 3500-lbs; a 3-inch round axle is usually rated for 6000- to 7200-lbs; and a 3-1/2-inch round axle will often be rated for 8K. Since your hubs are 6-lug types chances are that your axle is rated in...

  • Gross Trailer Weight Capacity is 15,000 Pounds but Axles are Rated for 7,000 Pounds Each
    It looks like the axles are rated for 7,000 pounds. I am assuming it is a tandem axle trailer. It is not uncommon to see the combined axle rating lower than the gross trailer weight capacity. This is because the trailer manufacturer is counting the rest of the weight as tongue weight carried by the vehicle.

  • How to Determine Axle Capacity on a 12 Foot Tandem Axle Utility Trailer
    With 5 lug hubs the capacity per axle could be any where from 2,000 to 3,500 pounds. It is likely that they are 3,500 pound axles but I would have to know the inner and outer bearing numbers stamped into the metal of the bearings to know for sure. This is going to be the best way to determine the axle capacity. Diameter of a round axle can help but isn't always definitive: 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:...
