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"

Staff very helpful figuring out hub for antique boat trailer. Arrived as scheduled. Went on easily. Well packed bearings. Good experience.


Great call with Helen T.,knowledgeable,emailed me a quote with the items we discussed,made ordering super easy.Placed order after 12:00 noon on Wed.,free shipping,received my order on Friday.Clear communication throughout the process.Totally sagisfied,my second time to buy from E Trailer,great buying experience both times.


Arrived on schedule. Took two orders, but finally got the correct hub/bearings. Easy install.


Very easy to install and zero issues after a year!


Product was a perfect fit! They arrived within 5 days with just standard shipping. Installation video was spot on and saved me some time for certain. I finished off the hub replacement with new radial tires, also purchased earlier from etrailer


Package arrived quickly with all parts complete and as described and ready to be installed. Fairly easy installation.


This was just what the doctor ordered! The most difficult part was getting the old corroded hub and bearings off. Once that was accomplished the new hub slid right on. Ove the fact that it was pre-greased. Thanks so much to Christine for helping me get the right part and for the fast delivery. You guys have a customer for life!


first class.


The fit was perfect. Delivery got post, took 10 days to arrive. Instead of 6.


Perfect fit, no grease needed, but extra filled so have towels ready. I took the trailer a couple hundred miles on the freeway with no issues


Everything fit fine and works perfectly


I was confused about the races so I called in and spoke to Justin, within 5 minutes he had answered my questions and given me the correct part#’s for my application- I went ahead and replaced both sides so I don’t have to worry about it again! He was super helpful, patient with my questions and very friendly! I really appreciate him! Great product too, they were ready to install out of the box and went on with ease!


Great Customer Service.
Thank you.


I bought a replacement axle and idler hubs for my utility trailer. Overloading with heavy firewood finally took its toll! Everything from showed up by UPS Ground right on schedule and the parts went together very nicely. The hub bearings are factory-lubricated, saving that critical step. I tested it out yesterday and the trailer runs fine. I would have to rate the products and purchasing experience as excellent (5 stars).


Very happy with these. Order came with wrong size seals for my trailer. I didn't know to check on that before ordering. Was able to order proper size, all good.


One hub came with the wrong seal. They covered the cost of the right one. It still wasted time and caused frustration. The studs are already rusting but have not seen road salt. I am doing a major overhaul on this trailer down to bare metal. I haven't road tested it yet. Good price. Easy shopping online.



You’re amazing! You made
an overworked, overwhelmed old man very happy!

My son and I were rebuilding a boat from ground up, it had to be finished by July 30.
Myself and eight old men were going to take the boat up the Mississippi River.
We’re going on a 4 day we survived CV-19 boat trip.

Anyway, the wheels fell off the trailer while traveling down the highway to test the boat. My son forget to tighten the lug nuts. The boat was ok but the hubs were destroyed, It took us 3 hours to limp 2000 some feet back home.

So I called etrailer this Friday the 10th of July in the afternoon, Danielle got the replacement hubs to me the 11th of July, Saturday afternoon, Amazing!

You have a customer for life! No one has ever ever treated me like that. I’m telling “EVERYONE” that the customer service at etrailer is second to none.
I’m so happy I shopped at etrailer.

Thanks Danielle!


Great high-quality hubs with pre-packed bearings. I replaced the axle and hubs on a Haul-Master 1195 lb. 4' x 8' folding trailer ( from that ubiquitous store that sells cheap tools - you know the one). I wanted a heavier duty axle with hubs that are standard sizes and could be repaired with readily available parts should I experience a breakdown on the road. These installed on my new axle without a fuss and were perfect on my first 300-mile trip hauling my enduro bike to the trailhead.


Everything I've bought from etrailer has been excellent quality at reasonable prices.


After 1 year they are working as good as new . put on a custom built home made light aluminum trailer to haul a small airplane . work great tires also work great


Excellent fitment and seem to be very strong products!


My order was 7 days late after receiving I realized I ordered the wrong part called an left message for someone to help me get it right still waiting for that call

Thanks for reaching back out. I have sent your information along to our customer service team and they will be reaching out to you in the near future.


looks to be made of quality material... I'm very pleased!... we haven't had the opportunity to test them on the road, yet. The only thing that keeps me from rating this with 5 Stars is the lack of a cotter pin included. Not a game changer but, it would have saved me a trip to the local hardware store. But, then again, any excuse to go to the hardware store is fine by me. Like I said... I'm very pleased with the hub and with etrailer's customer service!


Simply a breeze to install. The pre-packed hub was ready to go. The how-to videos were also helpful. My trailer was back together in minutes.


been great working with you all

  • Will Too Much Grease Cause Resistance in Wheels?
    The problem you are describing is odd because putting grease in should not cause resistance. I recommend disassembling your hubs and checking all the parts to make sure the bearings are seated correctly, the nut is tightened correctly and the seal is not broken.

  • Measuring For Replacement Idler Hubs On a 1997 Scamper 23L Pop Up Camper
    To ensure you get the correct hub for your 1997 Scamper 23L pop up camper you are going to need to pull one of your hubs off to determine what size spindle you have. You will need to measure the diameter of the spindle with a Digital Caliper # PTW80157 at the points on the image below for the bearings and grease seal. The Idler Hub Assembly # AKIHUB-440-2-EZ-1K fits a spindle that has a 1" diameter for the bearings and 1.249" diameter for the grease seal. The Idler Hub Assembly # AKIHUB-440-2-EZ-2K...

  • 1991 Starcraft Starflyer Replacement 4-Lug Pattern Idler Hub Recommendation
    I can get you most of the way there, but ultimately you'll have to pull the hubs on your 1991 Starcraft Starflyer to determine the correct hub. Pop up trailers typically have 2,000 lb axles. Since you have a 2K axle and a 4 lug bolt pattern this narrows down your choices to 2 different hubs, so just compare the bearing number to what I list below and choose the option that matches: - L44649 Bearings # AKIHUB-440-2-EZ-2K - L44643 Bearings # AKIHUB-440-2-EZ-1K

  • Replacement Hub with 4 on 4 Bolt Pattern
    A hub assembly like the # AKIHUB-440-2-1K you looked at with a 4 on 4 bolt pattern has a diameter of 5-1/2". At 2.31" you wouldn't be able to fit that bolt pattern on the hub since 4 on 4 implies 4 bolts with a circle that forms a 4" diameter. Typically you want to match up the bearings when looking for a replacement. This uses # L44643 bearings with an inner diameter of 1.00". The other option would be the # AKIHUB-440-2-EZ-2K which uses # L44649 bearings that have a 1.063" ID. You can...

  • Recommended Hubs For 22-AXC1 1800 lb Axle
    You have a galvanized 1200 lb axle that uses L44649 inner and outer bearings, typically used on PWC trailers, I'd go with # AKIHUB-545-2-LFEZ-2K which is pre greased and ready to install. The hub also includes the dust cap for E-Z lube or standard spindles as well as the lug nuts. The hub has a 5 on 4-1/2 inch bolt pattern which is very common. I'll link to an install video that you might find helpful..

  • Replacement Spindle and Hubs For 58000 Aluminum Hub On 1" Short Spindle
    You are going to need to replace your spindle with the BTR E-Z Lube Spindle # TRU44FR as your spindle that fits the 58000 hub is shorter than current spindles. This new spindle will place the grease fitting on the end of the spindle allowing you to grease the bearings through the spindle.

  • 4 Lug Hub and Spindle for Homemade Trailer
    For a 4 lug trailer hub for a 2,000 lb axle he part # AKIHUB-440-2-1K would work great with your wheels and then for a spindle that will fit it you'd want the # TRU97FR for a match for it. As far as auto steering though I am not sure what would work best for that.

  • Replacement Option for Axle With Metric Spindles for Haul Master Trailer
    Unfortunately, we don't carry a replacement axle that's compatible with metric hubs, but we do offer options that would get your trailer back on the road. We do offer hubs compatible with the # CE33201GA axle. For a 5 on 4-1/2 inch bolt pattern, I'd recommend going with part # AKIHUB-545-2-LFEZ-2K or for a 4 on 4 bolt pattern, use # AKIHUB-440-2-EZ-2K. If you'd prefer galvanized hubs for greater corrosion resistance, use # AKIHUB-545-2-G-EZ-2K for a 5 on 4-1/2 inch bolt pattern or # AKIHUB-440-2-G-EZ-2K...

    I have a way to help you find out what replacement hub assembly you need, but you'll need to verify some things on your end as I don't have a list of replacement parts for your trailer available.

  • Replacement 4 on 4 Bolt Pattern Hub Compatible With 1.063 Inch Straight Spindle
    A 1.063 straight spindle is compatible with an L44649 bearing. I'd recommend the Dexter # 8-91-05UC1-EZ hub as a replacement. The hub has a 4 on 4 bolt pattern and is compatible with the L44649 inner and outer bearing. Since your current hubs use lug bolts, it's considered hub-centric, which means that the lugs merely hold the wheel onto the hub, but the portion of the hub that extends through the pilot diameter of the wheel provides much of the load support to carry the weight of the...

  • Timbren Axle-Less System vs. Torsion Axles for a Sail Boat Trailer
    I recommend the Timbren Axle-Less Suspension System # ASR2000S01 over a torsion axle for your trailer for a few reasons. First, the Timbren System increases ground clearance without increasing your trailer height. The Timbren System is also easier to replace as you can replace one spring at a time. They also operate independently of one another to minimize bounce for a smoother ride compared to the torsion axle system. An E-Z lube spindle is included with the system, but a Trailer Hub...
