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"

I ordered the Idler hub (pre-greased) for the 3500 lb axle I have just installed it and it fit perfect

Have had no problems each trip is about 200miles and I have made numerous trips



by:

Finally got them in today (Postal Service delayed them in Memphis) and they are just as I ordered. Changed them out with the old hubs with no problem except the dust cover was just barely too big for my axle. No problem I just used by old dust covers.



by:

was an interesting job. had to buy a bearing puller to get of the old race then this went on and has been fine now for a year now. I bought both sides but only did the wobbly wheel as I don't like to fix what isn't broken yet.



by:

Parts came earlier than expected and was a super easy 15 minute installation.



by:

Prefect fit!

Put these on my boat trailer last year. Very solid and smooth.



by:

I’m very upset. I have ordered a lot of stuff from you, but this order really was bad. First off. It’s missing two Lugnuts. They gave me two that were too big as well. Also, dust covers do not fit. The solid ones do at least I think the ones with the rubber metal do not fit. I know they are hard to get in, and I am very experienced with putting them in and I could not get them to go in. Hopefully I haven’t tried them but the solid dust covers will work. If not, I will have to buy some bearing buddies. I don’t know if I will be using you again cheap Chinese stuff you’re selling

I am sorry that it came with missing hardware and that the grease caps are tough to tap into place. I will have our Customer Service team reach out to you.



by:

Ordering was easy. I had some questions so I called. Tammie was very helpful and took my order. Hubs arrived in 2 days. Installed easily and works perfectly. etrailer is a great company to do business with.



by:

I put the new hub assembly on for my Lil' Hobo retro camper trailer. The hub assembly doesn't come with a washer and nut for the spindle, so you need to save your old ones or buy these separate if you don't have them. I put it on with new tires and wheels, upgrading from a four bolt to five bolt pattern.



by:

Hubs were as described. Slipped them right on, adjusted and no problems.



by:

Converted my trailer to 5x4.5 so I could use standard rims. Everything worked great. I ordered 2 drums and 2 hubs. Everything included.



by:

Fast delivery
...the hub and bearing
set should include cotter pin had to replace them and for an additional couple of cent it far to Loews.
Thanks anyway



by:

Just a quick note to say thank you to eTrailer for not only the quality of parts received but also to Melissa for the dedicated service and attention that was given to me when placing my order.

THANK YOU MELISSA for all of your help!
Looking forward to my next purchase!



by:

Not much to see, but here are pics of the installed new hub and Bearing Buddy.



by:

My trailer originally had 5/ 4.75 hubs but decided to change to 5/4.5 hubs since my other trailer has the 5/4.5 hubs. Very happy with my purchase.



by:

Etrailer tech (George J) was great helping me pick this out for my trailer



by:

They look good, will be installing and finishing a total light job, complete switch to electric brakes, safety trigger, battery by the end of next week. Thank-you etrailer!



by:

Everything has worked as should



by:

Good price, right fit for my trailer per my research on your website. Short wait time on delivery. If product lasts, very pleased with overall experience with your company. Thank you.



by:

The right parts at the right price !



by:

Parts fit and worked as like they should. Fast shipping.



by:

Product works great and was easy to install. I don't think it came with the castle nut pin, which might be problematic for some people who don't have hardware collections at their work space. It might help those who are unfamiliar with hub installation to get an install guide with the product. I could see someone over tightening the castle nut and ruining their new bearings.

Great! I checked them after about 250 miles of use and they were still tight and in great shape. They were exactly as described and perfect for my application.



by:

Got pre packed hubs for boat trailer they fit perfect just as described!! Fast shipping. Would recommend A plus



by:

I used etrailer.com for the supplier for my utility trailer needs. I received everything I needed for a very fair price.

Ken J.

The hub/bearing assemblies I received for my utility trailer are still working great! Very good price as well.



by:

Perfect fit. I can always count on Etrailer for all my trailer needs



by:

Replaced hubs on 40 year old boat trailer. Cleaned up spindles with 350 grit sandpaper, packed bearings, filled remainder of wheel cavity with grease, assembled with new seal and old washer and hub nut. Good as new. I would have given them 5 stars if new washer and hub nut were included. I did learn that a dust cap driver can easily be made by cutting off a short piece of 2 inch sch. 40 pvc pipe. New lug nuts and dust cap were included.

  • Correct Hubs for Boat Trailer with L68149 and L44649 Bearings
    The correct trailer idler hub for your boat trailer is the Trailer Idler Hub Assembly for 3,500-lb Axles part # AKIHUB-545-35-K or part # AKIHUB-545-35-EZ-K if you have zerk fittings on the spindle. These are both pre-greased so there is no mess to be had.

  • Identifying Capacity and Replacement Parts for UFP Axle
    According to Dexter, this is a 3,750 lb torsion axle with a 90.3" hub face measurement. More than likely your axle uses # L68149 and # L44649 bearings with a # 168255TB grease seal. You will need to verify this information since Dexter did not have it available. Assuming that is correct, we have the following parts available depending on what you need: -Trailer Idler Hub Assembly # AKIHUB-545-35-K -Trailer Hub and Drum Assembly # AKHD-550-35-K -Electric Trailer Brake Kit # AKEBRK-35-SA -Dexter...

  • 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.

  • Do Different Timbren Axle-Less Suspension Systems Have the Same Camber and Ride Height
    The caster and camber could be the same on the # TASR35HDS03 and # ASR2KHDS05. The system has a slight manufacture camber. However, it is up to you on how much camber you have based on the installation. This can be changed using the included shims. As far as the ride height is concerned, these do not have the same dimensions. This will result in a different height between the systems when installed. The # TASR35HDS03 will also stick out farther. Since there is no real advantage to using...

  • 3,500 lb Capacity Idler Hub Recommendation that Comes with Marine-Grade Grease
    I have a solution for you, but the part # AKIHUB-545-35-K does not come with marine grade grease. Instead you would want the part # CE13511 as it is essentially the same spec hub in terms of bolt pattern and what spindle it fits except it does come with marine-grade grease.

  • Installation of Idler Hub on etrailer e65GR Trailer Axle
    The # e65GR uses hub assembly # AKIHUB-545-35-K. I have attached an installation video of the hub below. Since the hub is pre-greased that means the bearings are already packed so you can ignore those steps. You will still want to add additional grease as part of the installation which can be seen in the video. The base type is lithium complex so you can use something like the # L11390.

  • Trailer Idler Hub with 5 on 4-1/2 Bolt Pattern that Fits a 1 Inch Diameter Straight Spindle
    To find the right replacement hub for a trailer you will need the inner and outer bearing numbers stamped into the sides of the bearings or the measurements of the spindle to 3 decimal places. The measurements have to be as accurate as possible so I recommend using digital calipers # PTW80157. I included a picture that shows where to measure. If the spindle diameter is 1 inch the whole length where the bearings ride then hub # AKIHUB-545-35-K will not fit. It takes 2 different bearing...

  • Determining Correct Replacement Hubs for Car Dolly
    Your Picture helps narrow it down a bit but you still want to check your bearing numbers or measure the inner diameter of both bearings to be sure. You definitely have a 5 on 4-1/2 bolt pattern and it's likely a 3,500 pound axle on your car dolly. If this is the case then you probably have # L68149 for the inner bearing and # L44649 for the outer. If those are the correct bearings use part # AKIHUB-545-35-K for a replacement hub. If you can't read the bearing numbers then measure...

  • Replacement Idler Hub for Boat Trailer With 3500 lb Axle
    For a 3500 lb axle, each hub would be rated for 1750 lbs, but would still be referred to as a '3500 lb hub'. If your existing hub uses a L68149 inner and a L44649 outer hub with an Inner Diameter of 1.378 and 1.063 inches respectively, you do indeed have a typical 3500 lb axle and the etrailer branded # AKIHUB-545-35-K hub would be the correct replacement, assuming your existing wheels have a 5 on 4-1/2 inch bolt pattern.

  • Can Hub for 3,500 lb Axles be Used on Axles With Different Weight Rating
    That is a good question but the Trailer Idler Hub Assembly for 3,500-lb Axles # AKIHUB-545-35-K can absolutely be used on your axle rated for less than 3,000 lbs. What matters is that you have the same # L68149 inner bearing, # L44649 outer bearing and # 58846 grease seal because this means the hub will fit your spindle. These are most often found on 3,500 lb axles but can be used on an axle with less capacity with no issues.

With installing the new spindle this will allow you to use the standard size 3,500lb axle Idler Hub # AKIHUB-545-35-K. This hub has the 5 on 4-1/2" bolt pattern to mount your current wheels and tires. The now hub comes packed with bearings, races and a grease seal installed.
