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:

When the package arrived the two hub boxes were floating around inside of an oversized box. Opened up the hub boxes and the bearings, nuts and seals were all bagged up together and unprotected from one another. Hubs had missing paint on them. So the instructions should say have some black touch up paint on hand and make sure to blow all the metal out of the bearings before greasing them.




by:

Seems like it should be standard to throw a cotter pin in there as well as a washer. Now have to make a trip just to get those.
But got the right part and was easy to get.




by:

Etrailer has been a great source for axles and hubs. The customer service is far better than most online retail sites. I order frequently and speak with or email with customer service reps often.




by:

I bought this to build a spare tire mount on my dump trailer. I now have a spare hub if it is ever needed in an emergency. It works as it should and I hope to never need it for the intended purpose of an emergency hub.




by:

Parts were exactly what I wanted. I was able to see a reply to someone that had same problem I had and part numbers were given making my search extremely easy




by:

I have ordered several things in the past 10 years or more with etrailer and always had a positive experience with them.. From the time I purchase to do the day after it's delivered..They follow through A+++ Thanks Again..




by:

These were as advertised and of good qu ality.




by:

Working great, 1year and doing what I need them to do




by:

Good quality hubs. As stated by other reviewers, THE CAP SIMPLY WILL NOT FIT!! I was soooo hoping I could just manipulate them on there, but absolutely not. Had to put the old caps back on, and now need to find new ones elsewhere. - I replaced the hubs that were on a small 6.5x12 atv/utv trailer - a Diamond C. (WHY on earth they used 5 on 5 hubs instead of the easier found 5 on 4.5 hubs is beyond me. But, is what it is.) You will need to re-use your castle nut and whatever it is pinned in....either a clip or get a new cotter pin, along with using the existing washer from your other unit. THE RACES ARE ALREADY INSTALLED IN THE NEW HUB. This was helpful. The bearings need to be packed, along with putting the seal in the rear - no big deal. I will not necessarily be using this trailer in water - however, next time I will spend the few more dollars and get the galvanized hubs. Also has a complete set of small lug nuts. I just kept those for emergencies, and replaced with my long stainless steel lugs. My order from etrailer came a day ahead, for which I was EXTREMELY GRATEFUL. Had to change hubs outside - no garage - and as soon as I was done, it started snowing. AND I used etrailer's red grease, UltraLube L10320.


Comments
All of the above still applies. The hubs are great. Caps, not even close. Would order galvanized next time.

Packed full of grease and put on my 2016 jayco every thing seems to be good quality and exactly what I expected




by:

It worked well and went on with no prob lems.




by:

I needed to replace my bearing on my trailer hubs and since my current hubs were starting to wear I decided to purchase the fully-loaded hubs. I installed the easy-lube grease caps and everything went together perfect. Great product at an amazing price!


Comments
Still holding up great!

Put the new hub on my trailer an it works great thanks to all the great people at etrailer you guys are the best :O)




by:

Fits perfect! thanks to Madeline at Etrailer for getting me the right hub!!




by:

Great hubs would have given 5 stars but hub grease caps are so tight the centers were concave by the time I got them on using a rubber mallet to be as gentle as possible. Overall highly recommended to anyone building from scratch or just changing bolt pattern like myself. Dexter is a high quality product. I chose to use Bel-Ray waterproof marine grease and packed everything full. My trailer sees lots of abuse and is not stored under cover + I live in the Pacific Northwest. Lots of rain. Only takes about a half hour to grease and install if you have everything ready to go. As in old hubs removed and spindles cleaned up.

Great Service - Quick Delivery...
We

Thank you.

I built a utility trailer with my son from a 10K weigh capacity boat trailer and wanted to finish it properly. Bearings, hubs and drums arent an area to skimp on when building a trailer but where does a person find the RIGHT replacement parts. My local hardware and big box stores offer off brand replacement parts but of what quality and I'm still guessing as to proper replacement. I called etrailer and boy am I glad I had a micrometer handy. Their customer service walked me through all measurements and I'm assured the best quality products that will stand the test of time. I am grateful for their expertise and assured of quality. Thank you




by:

We received your parcel in great shipping order and we are very thrilled with everything. You saved us a lot of money as we had an old home built trailer that was loaned to another and they wrecked the trailer. Because you offer all that we need in parts to repair this trailer AND at a price we can afford, you have set in motion the ability for us to regain the use of the trailer we had to dismantle. My husband was happy he located you online.

We are waiting for cooler weather to do all the welding necessary and I promise to send you photos as we work on the trailer. Wish I had one of it before we dismantled it so you could have a before and after, but I will send the dismantled trailer and pictures of eTrailer's new parts so that everyone can see what a wonderful service you are offering.

My husband has already been bragging at work about what he saved and as I control the budget here so he can work without worry, THANK YOU for offering me help in keeping the costs down.




by:

Maybe I was expecting too much, but the bearings are dry and the way the hub, bearings, lug nuts and grease seal are shipped, they are loosely wrapped in plastic wrap so that they can come loose (at least one of the two that I ordered did) and get separated in the box with the other things if you order other items, which I did. It would have been nice if etrailer had specifically said that the bearings were sold/shipped dry and not already packed with grease. Just makes the job a bit messier than I had anticipated




by:

Have not built a trailer in 30 years. This is apicture of the one i built for good friend. This turn out very nice, heavy duty . All suspension and lights came from E-Trailer . This is the best place to buy and get information. Thank you, Ed.




by:

I ordered 2 complete hubs, plus Bearing Buddies, wheel and tire, winch and a fender on Monday. Monday night received an email that all had shipped, had it on my front porch on Thursday via UPS ground. Everything arrived complete and in good order. The website is worth its weight in gold for a DIY er like me as it contains a ton of info on how to measure, videos on what is included and great installation videos. Helps your confidence when you only do this kind of job once every ten years! My boat trailer is a 2002 venture V-2200.




by:

Hubs seem well made. Went together easily and went on the trailer with no issues.

Only problem I had was with how they were shipped. Bearings, seals, caps and nuts were just taped to the the hubs and put in a box with no packing material. One of the caps was crushed and unusable. Just used one off the old hubs.




by:

My order got to me very reasonable time frame and were packaged well. The hubs I ordered were as good of quality that I could get locally and these kits had dust caps, bearings, grease seals and lug nuts. And the price delivered to my house was $26 cheaper than here. Return satisfied customer.




by:

Great quality. Everything fit perfectly. Will utilize this company again.

The 1/2 X 20 stud would mean it is a 1/2 inch bolt with 20 threads per inch. There would be a third dimension that would be the total length of the bolt including the head, so if you wanted...

Measuring the grease seal journal is important because some spindles will use the same bearings but different grease seals. The last piece of information that we will need is the type of hub.
