E-Z Lube and Easy Grease-Compatible Assembly for Simple Lubrication

The grease cap on this hub is specially designed to work with your Dexter E-Z Lube or etrailer Easy Grease axle to make lubricating bearings quick and easy. Just remove the plug on the grease cap, attach a grease gun to the zerk fitting on the end of the spindle, and inject the grease. It will flow easily to both inner and outer bearings. Not only does this make lubricating the bearings easy, but it also helps to prevent corrosion of the hub. This is because you can lubricate the bearings without the mess of taking apart the entire assembly.

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"

Apparently the trailer world and automobile world are 2 different worlds. Auto mechanic for 28 years and my trailer will take a 5 on 4 3/4 Chevy wheel. I ordered 5 on 4 3/4 hubs and they are too small for my wheels. 1 person I talked to on the phone had me convinced I was nuts and had me take my old and new to tge local parts store. To makr hom happy. I took both hubs to my local Napa store and they came to the same measurements as I have always known. I then called back and Kimberly then instructed me on 3rd differnt way to take measurements and she claims I have a 5 on 5 hub and they do not have those currentl in stock in the etrailer brand. Beware before you order hubs as their measurements are different than the automobile world measurements. AND I had to pay my own shipping return.

You were on the right track however it was just a little bit off on where to measure to. For an odd pattern like the 5 bolt one easy way to measure is from the center of one bolt hole to the farthest edge of one of the two farthest holes. Or my favorite way to measure is from the center of one bolt hole to the one that is adjacent to it. From there you can use the chart in the FAQ below to see what bolt pattern you have. For example if it is three inches like yours then it is a 5 on 5 bolt pattern. We also have a printable template that can also help.


So far this hub seems to be great! It came in great condition, nicely greased, and installed very easily. Have not driven far yet but seem to be working very nicely so far.


Excellent axle and parts and great customer service from Joshua!!!
Delivering it to me in two days!!!
That doesn’t happen often nowadays!!!
Would definitely buy again from them and recommend E trailer!!!!!


Exactly what I needed. Hard to find 5 on 4.75 hubs. Fast shipping!


Perfect fit and easy installation on my tandem trailer.


Awesome service, communication, fast de livery.....


It seems silly to be so excited over a hub… but these made install so quick and easy it felt like cheating on a test. Pregreased, had nice plastic dust caps for shipping, pop them on, adjust and go. had both sides installed in under 25 minutes. the only hard part was getting the cap started in the hub, its a very tight fit. Highly recommend.


unfortunately, the wrong item was shipped. I advised rep. that it needed to fit over my brakes shoes. make sure you emphasize the drum/hub assembly must fit over your brake pads.


Item arrived quick and was as described. Worked great.


Ordered the new axle and two new hubs for a repair on my 6’ X 10’ single axle trailer, they were a direct bolt in getting me back on the road. They have been used for a lot of projects since. Would by again if needed. Holding up nicely. Being able to grease the hubs from the outside has saved a lot of time and hassle. And upkeep should avoid the problem that led to the new parts.



After a year I’m happy to report they are holding up great, no problems, so easy to grease and maintain.


Horrible, Horrible experience. Product showed in stock to be shipped and received within a few days of ordering. Placed my order based on that and almost immediately received an email that it wasn’t in stock and I would be notified when it was. Took 5 days to get a response from CS’s Amy H. When I questioned the misinformation on the site of “In stock, ready to ship” she told me that she had checked into it, had actually found enough product to fill my order and was “bumping me up in line” only to be told again when I questioned it a week later that it was not in stock at which time I was offered a more expensive part that required more labor on my end than I had quoted my customer. Finally received my items 4 weeks after ordering and wouldn’t you know it, right box, wrong hubs. Call CS & got “yep, the whole shipment was wrong with no foreseeable ETA for the right parts & do I want to continue to wait”. Again, Horrible experience. First time customer lost for good.

Customer Service will reach out to you.


Great service, knowledgeable, friendly people, and they have everything!


Fast shipping, great product! Thanks


I had to return them, because I ordered the wrong bolt pattern.


I ordered hub, cotter pin and washer, the hub came with bearings, seals, and races already installed in hub, seems to of good quality, good prices , fast shipping and the sales people are very knowledgeable and friendly, I will definitely be buying again from this company whenever I need trailer parts.

Trailer hub is still working like new, very good quality hub and bearings.


They worked perfectly and I received them in shorter time than anticipated which kept my project in forward motion


Great service. Upgraded shipping with no additional charge.


Very happy with this company. They had exactly what I needed. My order was processed right away and shipped out the next day. Very well put together team and looking forward to returning with any more of my trailer needs.


It's been one year since receiving these hub assemblies and I have had no issues whatsoever. Great customer follow-up by George J. I just ordered a couple of radial trailer tires which should arrive soon.


Replaced the Hubs on my Bass Tracker trailer with parts from E-Trailer. didn't measure correctly so I had to return the first ones but then settled on Galvanized hubs. Could not be happier. Much better quality than the originals.


Good service good products!


I looked around for a 5 on 4.75 and this was a great price. The hub went on without any issues. I was able to replace my hub in less than an hour. Thanks much for a great product.


The stud spacing on these hubs are not real common. You not only had the correct size but, the bearings and races fit very well. The customer support and fast shipping will bring me back.


One of the best companies I've ever had the pleasure of dealing with!


Order arrived as expected. Always a pleasure to deal with E Trailers. Never a problem.

  • TDE Replacement Hub
    I was able to do some research online and find compatible idler hubs for you. Although the # AKIHUB-5475-35-EZ-K version you'd looked at is the proper replacement, since it's a boat trailer I would recommend going with the galvanized version, which is part # AKIHUB-545-35-G-EZ-K

  • How To Check a Trailer Axle To Determine Bearing Sizes For a 5 on 4-3/4" Idler Hub
    The best way to verify the exact weight capacity for an axle is by checking the serial number on the axle. This is found an the axle tag or possibly stamped onto the axle tube. You can also remove one of your hubs to measure the spindle with a Digital Caliper # PTW80157. These measurements will help you to determine the axle capacity, I have included an image below which shows what to measure on the spindle.

  • Idler Hub To Replace Drum Brakes On Tandem Axle Trailer With 3,500LB Axles
    First you will need to check with the local laws where you plan on using the trailer as some areas require both axles on a tandem trailer to have brakes. If you can operate with brakes only on one axle then you can switch to an idler hub assembly but be sure to match your correct bolt pattern. 5 On 4-1/2" # AKIHUB-545-35-EZ-K 5 On 4-3/4" # AKIHUB-5475-35-EZ-K 5 On 5" # AKIHUB-550-35-EZ-K 5 On 5-1/2" # AKIHUB-555-35-EZ-K 6 On 5-1/2" # AKIHUB-655-35-EZ-K

  • Replacement Idle Hub for Pace 5x8 Enclosed Cargo Trailer
    It looks like your Pace 5x8 trailer has a Dexter Axle 3,500 lb axle. If you can confirm this then that means you'll need part # AKIHUB-545-35-EZ-K for a 5 on 4-1/2" bolt pattern or part # AKIHUB-5475-35-EZ-K for a 5 on 4-3/4" bolt pattern. I do recommend double checking what your bolt pattern is because while 5 on 4-3/4" isn't unheard of, the 5 on 4-1/2" bolt pattern is much more common. I'm attaching some helpful articles on bolt patterns that you can reference to double check.
