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"

Easy Grease Trailer Idler Hub Assembly for 2K Axles - 4 on 4 - Galvanized - AKIHUB-440-2-G-EZ-1K

Average Customer Rating:  4.9 out of 5 stars   (24 Customer Reviews)

Marine-grade hub is designed for trailer idler axles. Fits 2K Dexter E-Z Lube and etrailer Easy Grease axles with BT8 spindles. Inner bearing (L44643) and race, outer bearing (L44643) and race, grease seal, grease cap, and nuts included.


Comparatively priced! Heavy axle hubs exactly as ordered. They were for a special homemade application for which I needed to machine them. I was happy to find the cast iron had an even consistency and also found they were hardened where needed. Here they are buried in the front end of this homemade mini-loader. They're hard to see,but were a great fit delivered in a timely fashion.


The rep. I worked with, Sheryl H, was very helpful, and I received the products a day before I expected them. She gets a 5/5.
As far as the products go, one of the hubs looked a little dirty, and I wondered if it was used or returned previously.
More importantly, one of the bearings had a dent on the outer metal ring. Not sure if I can even use that one without having some future problem. I uploaded a photo.


Great service and product! Items shipped next day and the order tracking is way better than most trailer part sites. Items packed well in box is a big plus as receiving damaged parts can kill a weekend project plans. I will order all my related parts from etrailer.


Was as said fit perfectly ordering the other side next week


I have delt with e-trailer 3 times and they have always delivered as I ordered and quite timely.


Fits and good quality


All parts were received in good time and all fit perfectly ! Good Job !


Communication Good service .


Everything arrived in good condituion and installed without problem.


Good replacement for my utility trailer. Bolted right up. Good value.


I bought these for my boat trailer where one of it's hubs had a seized bearing. The ordering the etrailer folks helped me to get what I needed and when one of the hub caps came dented out of the box they sent me another one. I only used the trailer once since then but smooth sailing.


etrailer made researching and ordering the correct hubs easily. One stop shop. I am glad I found a complete kit that included the bearings and seals, and having the races already seated inside each hub was a big help.


Everything has held up fine over the past year. Had a 1,200 mile and 400 mile round trips and at least 20 short hails to the local ramp.


I am a returning customer who looks for quality products at a good value, and eTrailer does it again. And I paid for three day shipping, and my order was here by noon on the second day. Good folks, and a good business to work with.


great price. Saved a lot of $$ nice products. Fast service and shipping !!! Top of favorite list !





Fast shipping. Product is as described


Works great


Order received sooner than expected.


Nice job , everything looked great and went together, thank you

  • What is the Diameter of the Center Part of Trailer Hub AKIHUB-440-2-G-EZ-1K
    I went out to the warehouse to measure hub # AKIHUB-440-2-G-EZ-1K for you. At the widest part the part of the hub where the wheel fits around is 2-1/2 inches. Your wheels will fit because on a lug-centric set up (wheel centers to hub using lug nuts) the wheel center pilot hole does not have to be exact.

  • Correct Replacement Idler Hub for Trailer with L44643 Bearings and 4 Bolt Pattern
    The correct idler hub assembly you're looking for is the Trailer Idler Hub Assembly part # AKIHUB-440-2-G-EZ-1K. This is a complete unit with bearings, races, and seals. They are made of steel with a galvanized finish. I am not aware of any such aluminum idler hub.

  • Could Trailer Hub # AKIHUB-440-2-G-EZ-1K Fit Spindle that Measures 1 inch In Diameter
    Where are you measuring the 3-3/4 inches from? Just the portion that is 1 inch? With or without the threads? If the measurement of the spindle where it's 1 inch in diameter is 3-3/4 inches without the threads being factored in yes, the hub part # AKIHUB-440-2-G-EZ-1K would fit on it. If the 3-3/4 inch measured includes more of the spindle than that then you'd have a stub style spindle which we won't have anything for since it's much shorter in length than standard spindles.

  • Replacement Galvanized 4 on 4 Hub with 1.249 ID Grease Seal
    It sounds like you might be looking for the # AKIHUB-440-2-G-EZ-1K which uses a grease seal with a 1.249" ID. However, you will want to confirm that the bearings match as well. The AKIHUB-440-2-G-EZ-1K uses the inner and outer bearing # L44643 which is a 1" inner diameter bearing. As long as those also match, this will be the correct hub you're looking for and is compatible with EZ lube axles like yours. If you find a different bearing in the hubs, just let me know what you've got and...

  • Replacement Trailer Hub for Seadoo Trailer 4 on 4 Bolt Pattern
    There are 3 possible hubs for your trailer. To determine the correct hub you will need to remove one of the hubs it check for the correct bearing/spindle size. If you can read the numbers on the bearing you are looking for L44643 or L44649. If unable to read bearing numbers you can measure the spindle with a Digital Caliper # PTW80157. 1" Spindle(L44643) - # AKIHUB-440-2-G-1K for non EZ Lube Axle - # AKIHUB-440-2-G-EZ-1K for EZ Lube Axle 1.063" Spindle (L44649) - # AKIHUB-440-2-G-2K...

  • Replacement Boat Trailer Hubs with Bearing Kit and Matching Wheels and Tires
    It sounds like you have a standard 1 inch straight spindle. Because it is for a boat trailer, I recommend replacing your hubs and bearings with a galvanized hub to reduce corrosion. My recommendation is the # AKIHUB-440-2-G-EZ-1K for a 4 on 4 inch bolt pattern. The # AKIHUB-545-2-G-EZ-1K is the fit for the 5 on 4-1/2 Inch bolt pattern. I've linked the pages to the wheel and tire combinations that will work well with this bolt pattern. You will want to find the closest size to what...

  • Replacement Hub for Spindle With 1" Inner Diameter Bearings
    The # AKIHUB-545-2-G-2K uses # L44649 bearings with an inner diameter of 1.063" and also has a 5 on 4-1/2 bolt pattern. Since you need # L44643 bearings with an ID of 1" and a 4 on 4 bolt pattern the correct part would be the Trailer Idler Hub Assembly for 2,000-lb Axles - 4 on 4 - Galvanized # AKIHUB-440-2-G-1K. If you have an easy grease/EZ Lube axle then you would need the Easy Grease Trailer Idler Hub Assembly for 2K Axles - 4 on 4 - Galvanized # AKIHUB-440-2-G-EZ-1K instead.

  • What Spindle Should be Used with Trailer Hub # AKIHUB-440-2-G-EZ-1K
    The trailer hub part # AKIHUB-440-2-G-EZ-1K that you referenced is designed to fit BT8 spindles like the part # TRU94FR. This spindle is designed for 2,000 lb axles so it would easily work on a 1,000 lb total trailer.

  • Trailer Hubs and Bearing Buddies for Trailer Spindles with 1 Inch Diameter
    It sounds like your spindle uses L44643 bearings, There are a lot of hubs that use those bearings and have a 4 on 4 bolt pattern such as # AKIHUB-440-2-1K. However, the 1968 Bearing Buddies are designed to fit a hub that uses outer bearing M-12649 or 07100 which are not common. The hubs that fit your spindle take the 1.98 Bearing Buddies such as # BB1980A-SS or # BB1980A.

  • Replacement Hub for 4-1/8 Inch Long Idler Hub
    Both the # AKIHUB-440-2-2K and the # 8-258BTUC1 have a the same 4-1/4" length. This shouldn't be a problem, but you will need to know which bearings you have right now since these are different. They also have different bolt patterns so you will need to choose the right bolt pattern. The # AKIHUB-440-2-2K is designed to fit a BTR spindle and uses # L44649 inner and outer bearings. It has a 4 on 4 bolt pattern. The # 8-258BTUC1 is for a BT8 spindle which uses # L44643 inner and outer bearings...

  • Which Spindles Will Work With My Trailer Idler Hub For 2,000-lb Axle AKIHUB-440-2-G-EZ-1K
    The Trailer Idler Hub Assembly for 2,000-lb E-Z Lube Axles - 4 on 4 - Galvanized # AKIHUB-440-2-G-EZ-1K that you are considering buying is designed to work with BT8 spindles rated at 2,000 lbs, just as the hub is rated at 2,000 lbs. If you need a 1-3/8" diameter spindle, use BT8 Spindle for 2,000-lb Trailer Axles - 1-3/8" Diameter # TRU59FR. If you need a 1-1/4" diameter spindle, use BT8 Spindle for 2,000-lb Trailer Axles - 1-1/4" Diameter # TRU94FR. For a square spindle, use Square BT8...

  • Recommended Replacement Spindle Or Axle For Older Spindle That Uses Short Hubs W/ L44643 Bearings
    I have a few different options for you, but the older short hubs that your trailers spindles use are not made any longer so I do not have a hub only option for you. Instead you will either need to replace the spindle with a newer one such as the # TRU97FR which works with idler hubs # AKIHUB-440-2-G-EZ-1K which have the 4 on 4" bolt pattern you are needing, or replace the entire axle. If you choose to go with a replacement axle you will need to measure your current axle from hub face...
