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"

by:

I was in need of a set of hubs to go on a small enclosed trailer, time was of the essence and from the time I purchased the hubs they were delivered to my door step not even two full days later. For FREE. Which if you order parts for anything you know that’s insane !!!!!!! The hubs seem like great quality, they went on with zero issue. There was even included parts to use either a castle nut or a tab style washer, plus lug nuts ! And I have faith they’ll make the 3700 mile trip I have coming up. 10/10 would recommend to anyone.



by:

I wasn't replacing hubs but rather installing them on new axles (Timbren Axle-less system also purchased here). It was convenient to get the hubs here as I was also purchasing the Timbren system so I knew the setup would work together.

Being a novice at working on trailers, these hubs installed without a problem using the instructions provided. I had read several articles on problems with new hubs and the key comments I heard echoed was to be generous with greasing the bearings. It's been a year and I only have about 500 miles on the hubs but everything still sounds good.

I use the trailer for pulling my motorcycle so the load has been roughly 1200 pounds. The tires are ST145-R12 trailer tires.

The hubs are still sound after a year of occasional use. The configuration has worked well for me and still pleased with the results of the products Im using.



by:

Kit came with everything. Perfect fit. No issues or problems noted during the past year. Last November towed my 3500 lb boat/trailer package from Savannah GA to Port Charlotte FL and return at speeds up to 65 mph in addition to all the local miles racked up during the year -- all with no issues or problems.

So far so good ! Ive towed my boat wtrailer from Savannah to Port Charlotte Florida and return and many local trips with no incident.



by:

Put new brakes,drums, bearings and seals and hubs on boat trailer found all parts here and received really fast always order parts for trailers here and always will



by:

All products arrived correct and complete on the date promised. Will definitely order from here in the future.



by:

Delivered what I ordered as promised. Very easy to install. I did watch the tutorial video before starting was easy to comprehend.



by:

Quick shipping. The pieces appear to be of good quality. The welds looked solid. I haven’t put it on yet but it appears to be a straight forward installation. It’s going on a single axle trailer.



by:

These have held up for 30k miles so far and still perform like new. Serviced in 10k increments. Overlanding trailer weighs 1360 lbs empty 2k fully loaded.



by:

Unlike other 3500 lb idler hub, this one does not come pre assembled. Glad I had bought the grease as well! Easy to install thanks to excellent videos.



by:

Thanks to ETrailer i got my hubs i needed for my trailer and everything went smooth. Very satisfied with the results of service and product. I recommend ETrailer to anyone and everyone needing good service and parts.



by:

etrailer was quick to respond to questions with relevant and knowledgeable information. I would not hesitate to order from here again.



by:

Purchased to replace a similar hub that would not hold the grease cap. This is working as expected after 4000 miles of use. Pleased with the results!



by:

After a slight bit of technical confusing on my part the customer service staff set me straight and I was able to get the correct hubs for my application.



by:

Overall, I am quite pleased with my experience with buying from etrailer. The website is very detailed and helpful. The response to my questions took only a few minutes and was very helpful in placing my order. The parts arrived in only 3 days. Minor downsides was that one cotter pin was missing from an axle, one hubcap was bent rather oval and will take some reshaping to make it work, and one grease seal was slightly bent. Additionally, the axles I ordered were described as having 4 inch stubs, but only have 3 1/2 inch stubs, so I will need to weld on and extension to make them fit my needs. Overall though, I am pleased with the service. Nothing goes really perfectly these days with online shopping. I will be ordering more items from etrailer sometime today, and will hope that my minor issues will cause them to improve their service a little more.

Thank you for letting us know. I will share this feedback with our shipping department and Customer Service will be in touch.

I couldn’t find parts for my customers boat trailer . Nobody had a complete trailer axle . So I finally found etrailer they answered the phone I had all my measurements they took the time to search out what I was asking for . Awsome sales lady she knew what I wanted and found all my parts so I can replace the spindle on the axle
Nice to talk to a person instead of a answering machine
Thanks for your help



by:

I had a broken hub on a 21' pontoon trailer, so I went ahead and replaced both hubs on a #84 spindle with these. They appear to be good quality but I have yet to see how they perform on the road. They assembled and were mounted easily. The only issue I had was one of the grease seals was slightly bent and I had to bend it back into shape, otherwise no problem. One other thing, I don't believe you will be able to beat the speed of shipping from etrailer, and that's a very big deal with me. I will definitely use these folks again.

Casey W.

I just recieved mine, and the grease seals were also bent, I also had a lug stud that was buggered up pretty good on the end. I had to get the trailer back into service so itll be another day of knocking out the stud and putting in a new one. In general, looks to be good quality but I wish theyd pack the items better to avoid this type of problem.

These hubs are still working great. No issues. Would definitely buy again. I only go to etrailer.com for trailer parts.



by:

Fast Delivery! Great customer service!



by:

Customer Service helped me determine the best hub for my trailer - very knowledgeable folks at etrailer !!!

The parts were received VERY quickly - etrailer always does great with order fulfillment - and were of high quality. The hubs, bearings and hardware were all "correct" and installed easily on my Load-Rite boat trailer. One EZ-LUBE dust cap was received with minor damage (bent). I straightened it to allow immediate installation, and etrailer quickly responded to my request for a replacement - it arrived within days and didn't affect my overall project. But please note that a lot of reviews for hubs will mention damaged components (grease seals being most common) and so I'd recommend waiting for the parts to arrive BEFORE starting a hub rebuild... just in case you get a damaged part, too. And if you do - know that etrailer will stand behind their product and get you a replacement very quickly.

Also, if you have EZ-LUBE hubs like me - remember that you need to spin the hub while pumping in the new grease. Otherwise it just blocks up and will not fill the hub and bearing properly.

Good afternoon from Seabeck
Washington!

Your customer service is awesome, this was all due in to Darren and I will be back!

I have attached some pics of my application. the spindle was used for an old military trailer, the steering axel is different, as it is not a typical steer axle and is able to rotate 360 degrees. it pivots on a axel spindle and it was sheared off at the base just above the seal area.
so i had to cut it out and do a re-install with your replacement and it was a perfect match.

Thank you guys again!



by:

The hub assembly came a little later then I would have liked.BUT it was not e-trailers fault. It was covid-19's and China's fault. They are working great, went right on the spindles, no problem. Really have found a great place to buy parts. Keep up the good work.



by:

Product was a perfect replacement for the old sets that had failed. Packaging was poor, and wheel studs were dinged up because of it.

Will

After a year and over 1,000 miles I am still happy with these hubs.

Just bought these as a spare for my trailer. Also purchased a 3500 lb axle and couldn't be happier. Really solid and was easy to install.

  • Replacement Hub and Bearings for Fish Right River Master Jet Boat Trailer With Dexter 8-248 Hubs
    Thanks to the information and picture you provided I can definitely help. The replacement for your Dexter 8-248 is the # 84545BX. If you want a pre-greased option you can use the # 84545UC1-EZ. If you don't care about it being from Dexter the # AKIHUB-545-35-G-K you were looking at will also work. These all fit a standard 3,500 lb axle with # L68149 inner and # L44649 outer bearings.

  • Replacement Brake Shoes For Dexter 8-283 Trailer Hub Brake Assembly
    Hey Richard, The Dexter trailer hub 8-283 is a 10" x 1-1/2" design so you would need brake shoe kit # DX78FR for the right-hand side and # DX88FR for the left-hand side.

  • Replacement Dexter Idler Trailer Hub With 8-248 and T20 Stamped on Back Of Hub
    I can tell by the 8-248 and t20 stamped on your hub you will either need the Dexter Trailer Idler Hub Assembly for 3,500-lb Axles # 84545BX or Dexter Trailer Idler Hub Assembly for 3,500-lb E-Z Lube Axles # 84545UC1-EZ. The idler hub for E-Z lube axles includes a grease cap with rubber insert so that you can pump grease into the spindle for additional lubrication. Your spindle must have the grease zerk on the end of the spindle to use that option.

  • Replacement for Dexter 8-248 Idler Hub
    Hi Keith; the Dexter 8-248 uses standard bearings for a 3,500 lb axle. If you want a hub and drum assembly the # AKHD-545-35-EZ-K you were looking at will fit. The direct Dexter replacement for the idler hub is the # 84545BX or if you want it pre-greased the # 84545UC1-EZ.

  • Replacement Bearings for Stratos Trail Trailer With 84545 Hub
    The 84545 hub on your Stratos Trail Trailer uses the standard bearing combination for a 3,500 lb axle just like the # 84545UC1-EZ and # 84545BX. This means the correct bearing kit is the Hub Bearing Kit for Lippert, Dexter, and Al-Ko Axles - 3,500 lb with #84 Spindle # BK2-100.

  • Hub Recommendation for Dexter Trailer Axle part # T20BTR-EZ-7258
    The Dexter Trailer Idler Axle Beam with EZ-Lube Spindles # T20BTR-EZ-7258 that you referenced has a BTR spindle on it that takes a hub with an inner and outer bearing of L44649. This would not work with your hubs because they have inner bearing of L68149 and an outer bearing of L44649. To use the axle you referenced you would need to go with the Trailer Hub Assembly # 8-258-5UC1 instead. At 72 inches in length there are no axles we carry that would fit the hubs you have.

  • Is There a 5 on 4-1/2 inch Bolt Pattern Hub Available for Timbren Axle-Less ASR2KHDS03
    The Timbren Axle-Less system is compatible with hubs that have 5 on 4-1/2 inch bolt patterns. For just an idler hub you would want the part # 84545UC1-EZ or for a brake hub you would want the part # 84546UC3-EZ.

  • Availability of Dexter 3,500 lb Trailer Axle Hub that is Pre Greased Jamseson, you recommended
    The star shaped idler hub is how Dexter designs their hubs whereas the etrailer part # AKIHUB-545-35-K uses more of a flange. They are interchangeable though and there would be no issue going from one to the other. We have this exact style you are looking for with part # 84545UC1-EZ and it comes with a new spindle nut, washer, and cotter pin so it sounds like more what you are looking for. It is also pre-greased.

  • Right Replacement Hubs for a Trailer with 3500 Pound Axle and 5 on 4-1/2 Bolt Pattern
    In order to determine the correct replacement hubs for your trailer I will need to know the inner and outer bearing numbers stamped into the sides of the bearings. If the axle has a grease zerk fitting at the end then it is an EZ lube axle. If there is no grease fitting then it is a regular axle. Hub # 84545UC1-EZ is for EZ lube axles and it uses inner bearing L68149 and outer bearing L44649.

  • Should Lighter Off-Road Trailer Have Brakes Added
    In off-road situations it's gets a little more tricky with adding brakes to the trailer and having them actuate properly since the terrain changes a lot and traction is really inconsistent. I'd go with the part # ASR1THDS02 and idler hubs like the # 84545UC1-EZ and you'd be set.

  • Hubs and Wheel and Tires that Fit Timbren Axle Less Kit # ASR2KHDS05
    All of the parts you mentioned will work great together. The Timbren kit part # ASR2KHDS05 uses idler hubs # 84545UC1-EZ and the wheel and tire combos of part numbers # AM31952 and # AM31951 would fit well since the bolt patterns match correctly.

  • Looking For a Replacement 15 Tire and Wheel With 5 on 5 Bolt Pattern
    From the pictures you provided, you do indeed have a 5 on 5 bolt pattern. This isn't the most common bolt pattern though so if you were thinking about replacing the hubs as well, I do recommend swapping to the much more common 5 on 4 1/2 bolt pattern. However, due to the corrosion present in the pictures, I suggest pulling one of the hubs off to verify your bearing numbers. If the trailer is older, there can be a few different ones that were used.

This axle has a 89" hub face to hub face measurement with a 4" drop spindle and underslung design. The axle is rated for 3,500lbs and the spring seats on the axle measure 74". You can weld on some new Spring Seats # TRSS238 to the 70" measurement that you are needing. I do recommend new U-Bolts # APUBR-1 as your current bolts will likely have corrosion. Two...

    Make sure you are measuring from wheel stud center to wheel stud center when trying to determine the bolt pattern. The measurement you mentioned doesn't really match but it's very close to 3 inch which would be 5 on 5 inch. The correct idler hub to replace your Dexter 8-248 and has a 5 on 5 inch bolt pattern is # AKIHUB-550-35-K. I attached a help article on determining wheel bolt patterns for you to check out as well.

  • Is There a 2,000 lb Timbren Axle-Less Suspension System With Rise
    There is an option for one of these systems with a rise, but there isn't an axle riser kit for the Timbren Axle-Less Trailer Suspension System - 2,000 lbs # ASR2000S01. Reason for that is since these aren't a thru-axle and mount right to the frame, there isn't a way to lift that system. What you can use though, is a 2,000 lb kit that has a built-in 4 inch rise: - Timbren Heavy-Duty Axle-Less Trailer Suspension - 4" Lift Spindle - 2,000 lbs # ASR2KHDS04 This will give your trailer the...

Due to the Aluminum frame, I recommend putting a thin rubber pad between the steel mount and the aluminum I-beam.

Both hubs include the same Inner # L68149 and Outer # L44649 bearings the Shorelandr hub uses. Both these hubs will include a Grease Seal # 58846 with a 1.719" inner diameter.

  • Correct Replacement Hub for Boat Trailer with 3,500 Lb Axle.
    In most cases, a 3,700 lb axle will use the same bearings and seal as a 3,500 lb axle which means you can use any hub for a 3,500 lb axle on a 3,700 lb axle. The bearings for a 3,500 lb axle are L68149 for the inner, L44649 for the outer, and the seal is a 10-19. If this is what you have you can use the Dexter Trailer Idler Hub Assembly part # 84545UC1-EZ. Unfortunately, there's no way for us to know what you have for sure, even with the serial number.

  • How Do I Determine Which Replacement Bearings I Need For a Trailer
    Based on your inner diameter of 1-1/16 (1.063 inches) the replacement trailer hub bearings you need are # L44649. The matching race is # L44610. I highly recommend measuring the bearings and seals with a digital caliper tool to the thousandth of an inch. You would need to remove your hub to obtain. See the diagram to the right.

  • Which Timbren Axle-Less Suspension System for On and Off Road Trailer?
    Great question. The standard 2K system # ASR2KHDS01 is for standard highway driving only. The Heavy-Duty 2K system # ASR2KHDS02 will be compatible with wider tires for more of the combination use you are seeking. The # ASR1THDS01 listed for Off-Road Tires has suspension that is more robust for up to 2,200 lbs and has a longer arm for a smoother ride over a rougher terrain. For your application, I recommend # ASR2KHDS02. It will handle better for your fair bit of highway driving as...
