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"

Purchase a pair of hubs and leaf springs plus assorted hardware for an old trailer restoration. The pricing was great and the quality and shipping were equally as good. The trailer is a 1999 Haulin which seen it's better days. Thanks to Etrailer, I was able to order everything I needed at one time.

The hub seemed to be of very good quality. It shipped out and I received it very quickly. I have only one issue and that was the grease cap seemed a tad small and was extremely difficult to put on without damaging, but in all fairness that could be my lack of experience installing them rather than a product issue. before an after pictures attached

I recently purchased a set of hubs and bearings for my Jon Boat trailer. I purchased 4 on 4 hubs to put 4.80 X 12" tires on the trailer. Delivery was very fast. I received the hubs in two days. However, the hubs and bearings I purchased would not fit the trailer axle. I contacted etrailer.com and explained that the internal diameter of the bearings was much too small. The ID was 1" and the spindle of the axle was 1.25". They checked their inventory and could not find bearings with 1.25" ID. They agreed to allow me to return the hubs and bearings. However, after considerable looking I found that the axle is non-standard for this type of trailer and no one has hubs (4 on 4 for 4.80 X 12" tires) to fit the axle. I ended up purchasing a proper axle and installed the hubs I had purchased from etrailer.com. The people at etrailer.com were very considerate and helpful. I recommend them highly.

The hubs and bearing fit my seadoo trailer great. The reason for one star down is that the grease seals were the wrong diameter to seal on my axle and seeing as how this was a Saturday and I was 125 miles from home (trying to get this trailer road ready) I had to buy seals from a local auto parts store at $8.00 each (prices suck when your out in the country without many choices). Overall very pleased with the service and products. I would definitely visit etrailer again for my trailer needs.

The staff at e-trailer was very helpful and informative regarding their product. I learned several things about trailer equipment, in general from the staff, as well. I especially appreciated their efforts to assist me in solving a problem that arose several weeks after I had received the tires and wheels that I had ordered. The fix was to replace the existing hubs (4.5 inches) with new ones that were the standard 4.0 inch hubs.

I have a small 1200 lb Harbor Freight Tool trailer. The original bearings blew out and I had to replace the bearings, seal and hub. Went to our local Colorado Springs bearing supply house. I bought the hub, seal, bearings and cap for less that what they charged for one bearing, bought tires too - for less and better quality than what Discount Tire charged. Will be coming back

Hello, I also have a Harbor Freight trailer 1200 lb trailer. my hubs do not turn true. did you change just the bearing or the hubs too? I want to make sure these hubs fit this trailer?Jerry

Jerry M, In 2012 I replaced the spindle, bearings and tires on my Harbor Freight trailer. I had a local welder put the new spindles on the axle. Since this time, the trailer has remained true, no bearing issues, and no tire wear issues. Approx 2500 miles since then. Very happy with my decision to use eTrailer. Just wish they used FedEx and not UPS

My old trailer hubs were made of cast iron and the cup portion was machined and impossible to keep smooth. The new hubs were machined for the cups and were already installed. Next time when I need to repack the hubs and inspect the bearings I will have the option of putting in new cups and cones making them new allover. Thanks for a great product at a great price!! Bill


Comments
With almost 1500 miles on the trailer I have had no issues with the hubs or bearings. I did learn to keep a log of the miles on my trailer so I can keep track when to do maintenance on the bearings.

The actual hub is of exceptional quality as it is a cast hub and is a giant improvement over the tubular steel w/welded on lug plate I took off. Was not impressed with the fact that the MFG did not pack these in a cardboard box and just wrapped all the parts around the hub with tape, paint job on the hub was not the greatest but did not matter to me as I repainted it a different color to compliment my new wheels, the dust cap is flimsy and easy to dent unless you cut a notch the width of a hacksaw blade 1/2 way to the stop ring but again did not matter to me for anything but to keep the paint off the bearing race as I used my old bearing buddies. The hub is of automotive quality and I give it a 10 for quality, cost, fit and my hat's off to the service at Etrailer.

I am converting an old Coleman camper into a one room toy haler (model airplanes). The bearings in the wheels were shot. This pair of new hubs and bearings were cheaper then I could get the old hubs rebuilt locally. Also the old hubs had break drums I no longer needed. So the new hubs were lighter. Hubs look great and worked great. The new dust covers were not so great but my old caps worked. Shipping was unbelievable fast. All good stuff.

Ordering was fast and easy, shipping was quick. The Dexter hub kits were a good replacement for the boat trailer I put them on but the grease seals included in the hub kit were not the size I needed. I knew it when ordering so I just ordered the correct size seals at that time. I've ordered from etrailer several times......never had an issue. Good customer service and support.

Hub itself is better quality than the original hub I replaced on the trailer. I am extremely happy with the hub and it rates excellent. However the bearings, grease seal and cap are very cheap parts made in china. They rate poor in my book. What do you expect from a $3.25 China bearing? I installed the dry bearing into the race to check fit and it had flat spots and wobbled as I spun the bearing. All four bearings in 2 kits all had the same problem. I purchased 4 SKS bearings from local parts store @ about $8.50 each. They spin perfectly in the race. I upgraded the grease seal to a double lip instead of the single lip in the kit. I installed the cap with a rubber mallet and block of wood but they are thin and dented badly before they seated. They may work if you had a large socket or a collar that fit around the lip but if you contact the center of the cap in any way it will dent badly. I will replace those with a bearing buddy or better quality cap someday. What is the point of an assembly if you have to replace the substandard parts within it? Cheap bearing and single lip grease seal may work fine with light duty local hauling but I plan to run several hundred miles and believe I need better bearings and seals to handle the long miles without trouble. I did a 220 mile test trip yesterday and the hubs did not build any heat at all after the parts upgrades. I am not telling people to not buy this hub because the hub is excelent quality but I am telling people to plan on upgrading the bearings, seals and caps if they need a top quality trouble free assembly. Now let me tell you the good news. The price of the assmebly from Etrailer is good enough that even after the upgrades, the price is better than other hubs I found locally or on the web. Buy it but upgade it for the best possible hub assembly. I plan to purchase one more assembly from etailer as a back up. I do not want to be several hundred miles from home without a replacement I can install on the road if needed. Best $35 "insurance" I ever spent.

I needed to replace the hubs on my jon boat trailer. Etrailer had the exact hubs I needed, in stock. The description in their shopping cart made it easy to order the right part. They shipped promptly and I received the order within a few days. The hubs were well packed. Their quality is first rate. They even included bearings, seals, races which came installed in the hubs saving me some time (thank you!), and lug nuts at a price that was less than the bearings and seals alone were going to cost me at a local auto supply store. A diagram on their web site showed me how to install the innards and I installed both hubs on my trailer in a little over an hour. Thanks again, Etrailer.

    I did some research and there is no direct replacement for your hub due to how old it is. So in order to find the correct replacement, you will need to know the bearing numbers of your current hub because the information you gave is irrelevant. If you are unable to find them, you would need to use a digital caliper such as # PTW80157 and measure your spindle to the thousandths of an inch where the bearings ride. You can use the photo I've attached to see exactly where you need to measure. There...

  • Can L44643 Bearings and L44649 Bearings Be Exchanged

  • Recommended Replacement Hub for Dexter 8-91A
    I reached out to my contact at Dexter regarding the numbers you gave. They couldn't match anything and suggested that you most likely have a 8-91A, which is a 4 on 4 bolt pattern. That is a very basic trailer hub assembly and the replacement part is # 8-91-05UC1. This assembly comes with the L44643 bearings, the grease seal, the lugs and the grease cap. I'd suggest a bearing packer like # PTW1218 and the Industrial Strength Grease # L11390.

  • Correct Replacement Hub for a Trailer with Dexter L44649 Bearings
    In order to determine which is the correct hub for your trailer you will need to take some measurements of the spindle using dial or digital calipers for the most accurate measurement. I have included a picture that shows what measurements are needed. The difference between bearing L44649 and L44643 is only 0.063 inches but for bearings, it is critical to get the correct size. This is also why you cannot measure using a ruler or tape measure. It has to be dial or digital calipers.

  • How to Tell if Trailer has a BT8 or BTR Spindle Installed
    A BT8 spindle would have a diameter of .99 of an inch where the bearings would both install and would have a diameter of 1.24 where the great seal would ride. That would require a hub part # 8-91-05UC1 for an idler hub. A BTR spindle would have dimensions of 1.06 inch for outer and inner bearing plus 1.50 inch where grease seal would install. That would require an idler hub part # AKIHUB-545-2-G-2K.

  • Does a Trailer Wheel Center Hole and a Hub Bore have to Match
    The expert answer you have referenced is correct. A wheel that secures to the hub using bolts instead of lug nuts actually centers on the hub so the pilot hole of the wheel has to be exact. If it is too large the wheel can easily be off center and lead to all sorts of problems. Hub # 8-91-05UC1 has a center bore outer diameter of approximately 2.4375 inches; very close to 2.5 inches but not quite. If you use this hub and the wheels you are using have a pilot hole that is larger, it will...

  • Hub, Rim and Spindle Recommendation for 13 inch Wheel with 4 on 4 inch Bolt Pattern
    For a hub with a 4 on 4 inch bolt pattern that can fit 13 inch wheels with the pilot diameter of 2.5 inches the part # 8-91-05UC1 would be what you would need.

  • Trailer Hub Compatible with Caliper Measurement for Camping Trailer Axle
    Based on your photo it does appear you have the BTR spindle that takes the 1.063 inch inner bearings. The fact that it isn't a digital caliper with the precision of that thousandth does leave slight ambiguity but I am still confident you will want the Dexter Trailer Idler Hub Assembly # 8-91-05UC1. You will not need the # 8-91-05UC1-EZ you asked about because you don't have the grease zerk in your spindles. To confirm fit, I recommend putting your caliper on the grease seal location...

  • Replacement Bearing and Hub Kit Recommendation for Aluma 5310
    Your bearings having an inner diameter of 1-1/16 inch indicates you have a standard size spindle. The size matches the BTR spindle. The bearings part # L44649 that you referenced match what you'd need. For a hub that will fit this we have the part # 8-91-05UC1 for an idler hub with a 4 on 4 inch bolt pattern. Then if you need a 5 on 4-1/2 inch bolt pattern instead you'd want the part # 8-259-5UC1-EZ.

  • Availability of Trailer Hub That is 4 Inches Long, Has 1-1/16 Inch Bearings, 4 on 4 Bolt Pattern
    The best way to determine the correct replacement hub assemblies for your trailer is to retrieve the bearing numbers stamped into the metal of both the inner and outer bearings.
