E-Z Lube-Compatible Hub for Simple Lubrication

The grease cap on this hub is specially designed to work with your Dexter E-Z Lube 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"

Today, we're going to take a look at the galvanized trailer idler hub assembly for 2,000-lb E-Z Lube axles with the 5 on 4-1/2" bolt pattern. This is a marine-grade trailer hub assembly that fits the E-Z Lube idler axles. Now, the E-Z Lube axles, they are the one that have the greased Zerk fitting on the end of the spindle. That allows you to grease the bearings with out having to remove the complete hub assembly from the axle. This idler hub assembly includes everything shown here. It includes the bearing races, which are already pre-installed, the outer bearing race, and there's the inner bearing race. It includes both inner and outer bearings, grease seal, the grease cap, the E-Z Lube greased cap with the rubber plug, and then the 5 1/2" lug nuts. The nice thing on this model is the E-Z Lube compatible grease cap which makes lubricating your bearings very fast and easy.

Basically, once this is popped in and installed on there all you have to do if you need to add grease to your bearings is just pull out the black rubber plug and that will give you access to that Zerk fitting that's on the end of the spindle. Put your grease gun on there and put more grease in there. There is no need to disassemble the whole hub assembly off your axle. It's a pretty nice feature to have. Now, this hub assembly itself is a sturdy arrant 00:01:12 construction. Has a nice galvanized finish on it and this offers excellent corrosion resistance.

It's ideal for use on marine applications like on a boat or personal watercraft trailer or even on a snowmobile trailer. It is certified by USSAE standards and CSA, which is the Canadian standards. Application for this is 2,000-lb E-Z Lube trailer axles with the BT8 spindles. It is compatible with axles from most manufacturers like Dexter, Lippert, and Alco. Bolt pattern is 5 on 4-1/2".

The wheel size that would fit on this is 13" up to 15". The weight capacity is 1,000-lbs per hub. So, when you have one on each side that gives you your 2,000-lb maximum. Some information on all these parts that are included. The bearings for this, it uses the same inner and outer bearing part number which is the L44649. It has a 1.063 inner diameter.

So, if we put that as the inner bearing you'll drop that into the inner bearing race like that. Your grease seal, which has an overall diameter of 1.983, that would tap right in there just like that. Now the outer bearing, again, which is the same part number L44649 has inner diameter of 1.063. That will go right on the outer bearing race like that and then your zinc-plated E-Z Lube grease cap with the rubber plug, flange diameter is 1.99". That would tap right on just like that. Now for this video just to demonstrate where the parts go I just want you to know, of course, that you do need to pack the bearing with grease before you install them. I'm just showing you where they go so you are going to make sure that they are packed with grease and then as you go just to add grease you just use your E-Z Lube fitting to do that. It does include the 5 1/2" by 20 size lug nuts. Those are used to hold your wheel and tire assembly to the hub. So once you put your wheel up on your studs, put your nuts on and just tighten those down or torque them down to the correct specs for your application. But that should do it for the review of the galvanized trailer idler hub assembly for 2,000-lb E-Z Lube axles with the 5 on 4-1/2" bolt pattern.

I had no problem putting these new hubs on my Shortland'r PWC trailer. The inner grease seals that come with the package had to be swapped out for a different size, but that was a small added cost. The studs are plenty long for the wheels I have and with a shallow depth lug wrench, you might lose a little of the overlap on the lug nut. 577800

Fast Shipping! Product is good quality and the kit included everything I needed to get my trailer serviced. 498535

First off I have to give Natalie so much credit for all the help in finding the idler hub for my 35 year old boat trailer. Unbelievable all the digging she had to do. As for the hub it was the exact one I needed. I now know where to go for trailer parts. Don 368486

- AKIHUB-545-2-G-EZ-2K

The hub is still going strong after a year of regular use. I keep it greased and it does the rest. The price was right, too. This hub with bearings and seals was about the same price as the bearings alone at the local auto parts dealer. I do have two small negatives, neither of which take a star off my review. One, the dust cap fits very tightly and is hard to get on the first time. I had to grind the edges just a bit for it to go on. Second, the grease seal with the kit didn't fit my axle, although the bearings did. Check on this if your axle is a bit different. I don't remember the dimensions, but it was the ID of the seal that was too big. 673948

Everything arrived in good order and condition. What has really impressed me with etrailer is the customer service. I received emails from real people answering my questions and keeping me up to date with my order status. I even got a phone call from the shipping person making sure they facilitated my order in the best way possible for me. Count me as being really impressed!!!! I will be ordering all of my trailering supplies from your company in the future. I wish more companies ran this way. Great experience! 650312

- AKIHUB-545-2-G-EZ-2K

The grease seal was the wrong size for my axle. May have been my fault not sure. Had to uninstall and get new seals and reinstall. Of course it was 0 degrees out! 597680


Good to know that you were able to get the correct size grease seals for your axle. This kit includes the inner grease seal 10-9 that has an inner diameter of 1.5 and outer diameter of 1.987.

  • Replacement Hubs for Boat Trailer with L44549 Inner and Outer Bearings
  • I'm guessing you actually have bearings # L44649 and you either mistyped or the bearing number is difficult to read. Having # L44649 as both the inner and outer is a very popular combination on 2,000 pound axles. If you need to verify to be sure this is what you have measure the inner diameter of the bearings with a digital caliper, like part # PTW80157. It should meaure 1.063 inches. I've also done some research and found that bearing L44549 has the same dimensions as # L44649 so it...
