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 was blown away! We are leaving for a trip in a few days and unfortunately just discovered an issue with the Dexter Auto adjust brakes. Etrailer said the parts should arrive in 2 days and I was doubtful. Sure enough, they arrived when they said! Very impressed!


I was very satisfied with the quality of the Dexter OEM hub/drum and brake assemblies. These items were installed on our 2015 Airstream Eddie Bauer and were an exact match to the factory originals parts.


Well I ordered it in July when broke down in Buffalo. It was to be a spare part. It came. The neighbor took it off the porch and kept it. In August we returned and opened up the box. It was 11 bottles of Tea Shampoo/conditioner. I called etrailer and talked to Shawnee. She sent another hub assembly and arranged for UPS to pick up the hair products. The new hub a damaged box. The hub was there but the loose hardware was missing out the hole in the side of the box. I emailed etrailer and they sent the hardware items. They arrived today. Their response was quick. It didn't cost me anything extra. Of course, this was messed up and I'm happy I wasn't broke down awaiting for the parts. I think the etrailer part was good except for the packing of the second shipment. I'm not so impressed with the freight company, UPS. The hub is 39 pounds and need additional box reinforcement.

However, other orders in the past have come with no problems.

It rides in the trunk of the RV just fine.


Representative was helpful while ordering and installation video was a good resource.


Etrailer came through for us when we had an emergency need for new brakes on our Airstream before we travelled the Million Dollar Hwy. Marcus and the team expedited our parts and followed up throughout the delivery.


eTrailer was very helpful on the phone making sure I bought the right part. It arrive fast! And in great shape.


Hub/drum assembly arrived in good condition, and should provide sensible insurance against bearing failure on our Oliver Elite II travel trailer with Nev R Lube bearings. I have always received good service from etrailer


No problems. Works as should.


This was a replacement for a Dexter brake that was on a 4 year old Airstream that had less than 9000 miles on it and proved to be defective. Dexter wouldn’t honor the 5-year warranty since I wasn’t the original owner. Service from etrailer was great but I wouldn’t select another Dexter product if there were other options.


There was no packing material in with drums and were beat up from moving around. luckily only one cap damaged. Two of the drums were not machined properly and dust cap that was not damaged was loose and would not stay in drum. two of the drums were correct and dust cap tapped in normally.

I am sorry to hear that the drums not machined properly. I will have our customer service team reach out to you.


Lots of talk about knock off bearings. These hubs have the Timkens and packaged well. Delivered quick!


My camper was stranded up in the mountains of NM and when I got the drum it fit fine but the washer and nylon stop nut were way to small. Thank goodness I didn't throw the old ones away. Now that the camper is home I'll loctite and re-torque the nut.




I was glad to find and get a OEM part’s at a fair price. The fit of the drums was exactly as originally drums. I will continue getting my parts from etrailer as I need to replace parts for my 5th wheel and utility trailer.


Ordered part 008-388-80 (dexter nev-R lube hub and 42mm bearing) for my 2017 Airstream international signature 30rb. Waited on hold for about 40min to talk with Adam who helped take my order and confirm they had the parts as shown on the website. Parts arrived within 3days and are a perfect fit. Adam was extremely helpful and respectful. Will use etrailer again for future purchases.


The parts that I got were top Quality at a good price and the service was even better when I call about the parts and installation issue they were very helpful I would recommend them to anyone who is looking for parts for there trailer and plan to do the work themselves. Thank again etrailer


Tammy went above and beyond to help me in a pickle and it worked out perfect!


Everything ok. Thanks for the good service. Since I purchased this hub and bearing sssembly as a spare, I will not be installing it, only if one goes out.
Thanks for the follow up. I have and will continue to recommend you.


Perfect fit. Relatively easy to install, good etrailer instructions. When you install these do the shoe adjustment manually at first. After that the take care of themselves.


Great product, great customer service and the best price I could find!
Saved a lot of money ordering from


No problem with replacing never lubricants hubs. No problem since.


I had a unusual break drum but thanks to the help line she was able to find a replacement. Fit Right into place. Delivery was fast and on time.


The correct part was delivered on time. The person I ordered from was friendly most accomidating and had excellent knowledge of the part and how I wanted it delivered.



Product performs as it should. Thank you


shipped in two different packages, one package made it on time. the other is lost in the sauce with UPS. packaging was poor.

  • Replacement Hub for Dexter 5200 lb Axle with Nev-R-Lube Bearings
    There is no difference between these parts the 8-388-30 is simply Dexter's updated part number for the # 8-388-80UC3. The part will work on Dexter Nev-R-Lube Axles that are 6,000 lb capacity and will give you a 6 on 5-1/2 inch bolt pattern. This is the same assembly used on 5200 lb axles as well.

  • Replacement Hub/Drum for 5,200 Axletek Axle with Nev R Lube Bearings
    Yes, since the Axletek 5,200 lb Nev R Lube axle use the 5,200 lb 42 mm Nev R Lube bearings the replacement hub/drum part # 8-388-80UC3 that you referenced would fit and work great.

  • What is the Torque Spec of the Spindle Nut on a Dexter E-Z Lube Axle
    In order to remove the hub/drum on your trailer you will want to first remove the spindle nut. Once the spindle nut is removed you are going to want to take a hammer and tap the outer portion of the drum as well as the hub face a few times to break loose an rust/dirt. You should then be able to pull the drum off. Once the drum is off you can wipe down the spindle and then spray the braking assemblies with brake cleaner. You can then install the drum and spindle nut. The spindle nut will...

  • Replacement 6k Trailer Brake Hub that Uses Nev-R-Lube Bearings
    For a 6,000 lb axle we have the trailer hub part # 8-388-80UC3 which has Nev-R-Lube bearings in it. This is designed for a 12 inch brake assembly as well. This is also a Dexter brand hub which is widely considered to be a nicer quality hub than Axle Tek.

  • Do You Grease Inside Of Dexter Nev-R-Lube Hub Or On The Spindle Before Installing The Hub?
    The Trailer Hub & Drum Assembly # 8-388-80UC3 you were looking at is designed specifically for 42mm Dexter Nev-R-Lube axles and you do not grease any of the components. This hub has sealed bearing cartridges which do not get greased. Now if you were installing a standard hub with normal bearings then yes, you would pack the bearings with grease, and grease the spindle before installing the hub. I included a video review of the # 8-388-80UC3 for you to take a look at.

  • How To Install the Spindle Nut on a 12,000 Pound Dexter Axle
    I spoke to Dexter and they said there is a bit of a process for installing the spindle nut properly. 1. You will need to thread on the inner nut, rotate the hub, then tighten the nut to 100 foot pounds. 2. Loosen the nut to remove the torque, making sure not to rotate the hub. 3. Hand tighten the nut, then back it off 1/2 to 3/8 of a turn 4. Place the tang washer on the spindle and bend two tangs inward over the nut, This will keep the inner nut from turning while torqueing down the outer...

  • Can EZ Lube Hub be Replaced with Dexter Nev-R-Lube Hub without Replacing Axle
    Dexter Nev-R-Lube hubs such as the part # 8-388-80UC3 are designed to fit Dexter Nev-R-Lube Axles. These hubs use a special cartridge style bearing that is only compatible with the spindles on a Nev-R-Lube Axle. With this in mind you would not be able to change from an EZ Lube hub to a Nev-R-Lube model without replacing the entire axle. If you are needing to replace the hubs on your trailer I will be happy to recommend a hub and drum assembly that will work well. Please just let me know...

  • Is Dexter Trailer Hub & Drum Assembly Sold Individually
    Not a stupid question at all. The Dexter Trailer Hub & Drum Assembly, part # 8-388-80UC3 is sold individually. If you find that down the road the inside of the drum is scored it can be resurfaced. The cartridge bearing for this assembly is part # 31-73-3. There is only one bearing for this hub and drum.

  • Which Electric Drum Brakes for Dexter Nev-R-Lube Axle 410980-02 Hub 8-388
    I sent this to Dexter and this is what they sent back: I checked the number and it not a good hub number, and wheel tried pulls up 3,500 sprung axle from 2006 that doesn’t use a Nev-R-Lube hub. I would ask for confirmation on the number or some pictures of the product to confirm replacement parts that will work. If you can get me the info on your hub I can go from there. Look for a number on the outside of the drum.

  • Replacement Hub and Bearing for Dexter Nev-R-Lube Axles
    Normally you would go by the bearing numbers stamped into the sides of the bearing. If you do not have those bearings though then the spindle will have to be measured. Since you have Nev-R-Lube axles though there are not that many options. If the spindle is 50mm in diameter then # 8-385-81SP or # 8-385-82UC3 would be correct. If the spindle is 42 millimeters then you would need # 8-388-80UC3 which has a 6 on 5-1/2 inch bolt pattern.

  • How Often Should Trailer Hubs/Spindles/Bearings be Greased
    It may not be a bad idea just to do a quick visual inspection of your hubs every 3,000 miles (or after a long road trip) but you really don't need to add grease to the bearings until you either reach 12,000 miles or 12 months (granted they are in good working order). When you do add grease at the 12,000 mile or 12 month mark you will want to use the exact same grease that is already being used for your bearings. Some greases are not compatible with each other and will actually cause all...

  • Recommended Hub And Drum Assembly For Dexter 5200 lb Axles
    The self adjusting brakes need an initial adjustment when you install them and then the self-adjusting will kick in. If you have already done the initial adjustment, the 5 mile trip should allow your brakes to work properly. If the brakes are not working properly, it may be a sign that your drums assemblies are worn down or it may just mean you need to adjust your electric brake controller settings. If you want to ensure you have working bearings, seals, and hubs, I recommend the Trailer...

    The wheel stud used on part # 8-388-80UC3 is part # 7-262. These are drive-in 1/2 inch studs that measure 2.7 inches long, and will work well for your hubs. If you need lug nuts I recommend part # CE11051.

The Trailer Hub & Drum Assembly - 6,000 lbs Axles - 6 on 5-1/2 - Nev-R-Lube # 8-388-80UC3 is the replacement assembly.

  • What Brake Replacements Do You Recommend for My Dexter 5200 Pound Axles?
    For a great option of Nev-R-Adjust brakes on your 1999 Jayco Designed 5th-wheel trailer, I recommend the Dexter Nev-R-Adjust Electric Trailer Brake Assembly - 12" - Right Hand # 23-459 along with the Dexter Nev-R-Adjust Electric Trailer Brake Assembly - 12" - Left Hand # 23-458. Both of these brakes have a 6,000-pound capacity and will have enough weight capacity for your 5200 pound axles.

  • Replacement Hub/Drum and Brake Assemblies for Dexter Nev-R-Lube 5,200 lb Axle
    Your Dexter Nev-R-Lube 5,200 lb axles use a 42 mm bearing cartridge that has a 6 on 5-1/2 inch bolt pattern. The correct replacement kit you would need that has the hub/drums with bearings pre-installed is the part # 8-388-80UC3. You would not be able to go to an EZ lube type since you have a Nev R Lube spindle setup. This is a much better setup anyway. For a right hand brake assembly you would need the part # AKEBRK-7R-SA and for left # AKEBRK-7L-SA.

    Your Pilgrim International Open Road 357RLDS definitely has tires needing replaced. It is not uncommon to use LT tires on trailers, but it sounds like they have some dry rot going on. The stamp on the wheel rim unfortunately is not anything I'm familiar with so I can't help with that, but I can tell you that most trailers use a zero offset meaning that the mounting surface of the wheel to the hub is in the direct middle of the tire. The triangular or circular cutouts in the wheel are...
