E-Z Lube and Easy Grease-Compatible Hub 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"

I ordered 5 x 5.5 hubs for my boat trailer. When they arrived, they were 5x5 so I returned them in person so I could exchange them but found out they would need to be shipped. I received the second set and they were also 5x5. Each time the boxes they came in were marked 5 x 5.5, so they didn't match what the labels on the boxes said. I was told I would receive a return shipping label via email but I haven't received that yet. Someone needs to work on quality control in the shipping department. If the next set is not correct, I will be doing business with someone else.

I sincerely apologize that the hubs have been the incorrect bolt pattern. I checked and I see that we have now emailed out the pre paid labels to you.


Replacing the hub on my trailer was easy using the website. They have a page to find which lug pattern your old hub has.The kit includes the bearings, seals, races already installed, washer , carter key and endcap.All I had to do was grease the bearings, pop the seal on and install the hub.I also replaced the bearings on the other hub using the bearing kit which has all the parts you need.


I recieved the part it didn't have lug nuts or grease caps all and all not happy

It wouldnt make me happy either to be missing so many pieces! I am sorry it arrived this way. We definitely want to make sure you get all the components and I have sent your information to our customer service team reach out to you.


great fitting hubs


the order was just what i needed!


Perfect fit. Easy install. Fast delivery


Showed up twice not 5-5.5 but 5x5.0


Good selection fast delivery.


everything is great with the tires and rims along with the new trailer hub.
i have them on a 16 foot utility trailer that is worked hard. and in my town i could not get tires or rims locally. etrailer has every thing and good quick service. thank you. i do recommend you guys.


Burned out the bearings on a home-built trailer with this oddball spindle size.

Product was exactly as specified, delivery was quick. The product was not available locally, and I thought I was going to be down for a week or more waiting for the kit, but it was here in a couple of days. The price was also significantly less than ordering it in at a local trailer supply outlet. It's wonderful to be pleasantly surprised.


Exactly what I needed and arrived two days early.


Fast delivery, perfect fit, couldn’t be happier


The hub arrived as expected and looks great. I have been waiting on one of your tech guys to give me dimensions so I could complete my drafting using your hub. He never has gotten back, so I just ordered it and have already measured it and am back drawing.


Product was exactly as described and of good quality. Will certainly use etrailer again for my trailer needs


Hubs have been used extensively and have performed superbly. The hubs are on a 5x10 single axle trailer.


etrailer's website, product availability/information and customer service is literally unmatched on all accounts. I'm a regular customer for these reasons. The Q&A section on the website couldn't be more helpful. Product descriptions are very detail oriented. 12 out of 10 consistently.


Delivered on time and as advertisted.


Customer Service Rep Alexis was a great help... Alexis was responsive to my questions in a timely and professional manner... Glad Alexis was able to help me get the right stuff...!!!


These hubs fit perfectly. Good staff, and perfect parts selection. I would buy from them again.


Easy to compare to original. Arrived as specified and packed securely for shipping!
Good quality product!!


Every thing was perfect with my order, the people were friendly and also help full. Got my order rushed to me and I got what they promised.


Quick delivery, packaged well and exactly what I ordered. Excellent service and will definitely shop again. Thanks



Just put two of the new hub assemblies on. Worked perfectly!


I ordered wrong hubs and customer service helped me right away thank you

    The elements that would need to match up are the inner and outer bearing reference number, the capacity and the bolt pattern. The 5 on 5-1/2 bolt pattern idler hubs we offer use a L68149 inner and L44649 outer bearing. Your existing bearings should have the bearing reference numbers stamped on the bearing cages. If not, measure the surfaces on the spindle where the inner and outer bearings ride. The spindle at the inner should be about 1.378 inches in diameter and 1.063 at the outer....

    For a hub that fits the Timbren Heavy-Duty Axle-Less Trailer Suspension - 4" Lift Spindle - Wide Tires - 2,000 lbs # ASR2KHDS03 with a 5 on 5-1/2 bolt pattern I recommend the Easy Grease Trailer Idler Hub Assembly # AKIHUB-555-35-EZ-K. This idler hub will fit a 15" wheel like the one you have and has a weight capacity of 1,750 lbs. Keep in mind, you will still be limited by the 2,000 lb capacity of the Timbren system.

    For a replacement hub, you'll want to match the inner and outer wheel bearing numbers of the existing hub to those of the replacement. You'll also want to choose a hub with a grease seal that's compatible with your spindles, and if you're wanting to reuse the same wheels and tires, you'll also want to choose a wheel with a matching bolt pattern. For tires, you'll want to choose tires whose combined weight capacity exceed the weight of the boat and trailer. I'll link to an article that...

  • 3,500LB Hubs, Brakes and Spindle Needed For a 5 on 5-1/2" Bolt Pattern

    I have a hub for your trailer, but unfortunately we don't have a hub that will work with the inner diameters of your current bearings.

This hub uses the inner bearing # L68149 and outer bearing # L44649 and it comes with a grease seal that has an inner diameter of 1.719". If your current hub uses the same then this is an exact replacement. If you can't find...

  • Replacement Trailer Axle For Dexter #9 Torflex 2,200LB Torsion Axle
    As we do not carry any torsion type axles I recommend installing the Timbren Axle-Less Trailer Suspension System # ASR1THDS01. This axle-less suspension will provide you with better ground clearance as well as stronger components. The Aeon progressive rate springs work better to absorb road shock and provide a better ride quality. The springs are rated for 2,200lbs like your current Dexter Axle #9 Torflex D2762739 but the spindles used are rated for a 3,500lbs axle giving you a stronger...

  • Recommended Axle-Less System For 2000-Lb Off-Road Trailer
    Since the trailer you are building is 2,000-lbs or less the axle-less system I recommend is part # ASR2KHDS09. This is the Timbren system with a 4-inch drop and it is designed for off-road tires. It has a weight capacity of 2,000-lbs and has EZ Lube spindles that make it easy to grease the bearings without having to remove the hubs. This system has a 4-bolt brake flange. If you do not plan on adding brakes I recommend part # AKIHUB-555-35-EZ-K idler hubs. This hub has a 5 on 4-1/2 wheel...

  • Timbren Axle-Less Suspension System Compatible with Jeep for Matching Trailer
    For the Timbren Axle-Less kit compatible with the bolt pattern of 5 on 5 like a Jeep, you would need the 2,200 lb capacity # ASR1THDS03. The spindles on the Timbren system are a little larger than their thru-axle counterparts, so the 3,500 lbs # ASR3500S06 will only fit larger hubs that won't have the bolt pattern you seek. Using # ASR1THDS03, you can then use the Trailer Idler Hub Assembly for 3,500-lb E-Z Lube Axles - 5 on 5 # AKIHUB-550-35-EZ-K or the Trailer Hub and Drum Assembly...
