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 trailer idler hub assembly for 2000 pound EZ lube axles. This one has the 4 and 4 inch bolt pattern. This trailer hub assembly fits the EZ lube idler axles. The EZ lube axles are the ones that have the grease zerk fittings on the end of the spindle that allow you to grease the bearings without having to remove to complete hub assembly. Comes with this EZ lube compatible grease cap, which when installed there it'll make lubricating your bearings very fast and easy. All you have to do on an EZ lube axle, pop out that rubber plug, there's your zerk fitting, put your grease gun on that zerk fitting, and you can pump grease in there to maintain your bearings.

There's no need to disassemble the whole hub when you're greasing the bearing. With the EZ lube you can put the grease right in through that zerk fitting. This idler hub assembly will include everything shown here. It also includes the bearing races, which are pre-installed. The outer bearing race right there is installed in the hub and the inner bearing race right there is installed. Comes with both the inner and outer bearing, the grease seal, the grease cap with that rubber plug ...

the EZ lube grease cap with the rubber plug, and then 4 1/2 inch lug nuts. This hub is a sturdy iron construction, has a nice zinc and rich paint finish over it. This is certified by USSA standards and CSA, which are the Canadian standards. The specs on this: the application is for 2000 pound EZ lube trailer axles with the BT8 spindles. It is compatible with axles from most manufacturers including Dexter, Lippard, and Alco. The bolt pattern on this is a 4 on 4 inch bolt pattern.

Weight capacity is 1000 pounds per hub, so when you use this with one on the other side of your axle it'll get you your 2000 pound maximum. On the parts that are included: this hub does use both the same bearing for the inner and the outer, it's part number L44643, that has an inner diameter of 1 inch. On the inner bearing you can see it will fit right into that bearing race like that, use your grease seal, has an overall diameter of 1.983, put that like that, and you tap that all in to secure that in the back. Your outer bearing, which is the same part number L44643, has the 1 inch inner diameter. That would go on the outer bearing race just like that. Then you take your zinc plated EZ lube grease cap with the rubber plug, tap that right into place just like that.

This grease gap does have a flange diameter of 1.99 inches. For this video I'm showing you where the parts go, but when you do install this initially you do want to make sure the bearings are packed heavily with grease and then install them like that. You don't want put them in without grease. Once they're installed from the first time, then when you have on an EZ lube axle you can access it and maintain it by pumping grease through that zerk fitting on the EZ lube axle to maintain it. It also comes with the 4 1/2 inch x 20 size lug nuts. The lug nuts are used to hold your wheel and tire assembly to the hub. Once you get your wheel up on the studs, go ahead and put your lug nuts on, go ahead and tighten them down, and torque them to the specs for your application. That should do it for the review of the trailer idler hub assembly for 2000 EZ lube axles. This one is a 4 on 4 inch bolt pattern.

- AKIHUB-440-2-EZ-1K

The axle hubs are great. I really liked that the bearing races where already install in the hubs. The produced was just as shown in the pictures, you didn't have to guess on what was included. All I had to do is pack the bearings with grease, clean the axle shaft a little, install the hub kit with a little more grease, reuse my old washer ( spacer ). Install the old nut and carter pin, install the cap, put on the tires with the new lug nuts ,that came with the kit. It did not take but about 45 minutes to the side. I was in no big rush! Me and my 12 year old Grandson fixing up a old 1970 Appleby Boat and Trailer. Thank You David Hutchinson 683226

The two new trailer idler hubs fit perfectly with the trailer spindles. The whole process of removing the old ones and installing the new ones was relatively easy without any difficulties at all. It also appears that the quality and the engineering designs of the new hubs are much better than my old ones. These are great products with good prices. A couple of pictures are attached for more info. Thank you... 503610

- AKIHUB-440-2-EZ-1K

The replacement hubs and bearings arrived before I thought they would. Just packed the bearings with grease. Greased the spindle and hub races; assembled and put on my trailer. Good to go. Don't like the hub cap that came with kit. Prefer solid caps that came on the trailer originally. 387433

- AKIHUB-440-2-EZ-1K

After finding etrailer online, I ordered the parts I thought I needed (Hub and bearing kits). They arrived within days, they fit perfectly and they are still going strong on a well-used trailer. I would go to them first if I need anything else. Very satisfied. 375520

Still frequently using the trailer with your wheels and hubs. No problems at all. Thank you.

  • Replacement Hubs with L44649 Bearings and Replacement Hubs with L44643 Bearings
    If the spindle is 1 inch in diameter exactly at both bearing locations then they are L44643 bearings. If it is slightly over 1 inch then they are L44649 bearings. You can also measure the inner diameter of the bearing and that will help. And if you can email me a picture I might be able to make it out. I have seen a lot of bearings over the years! If you do end up having L44649 bearings AND the spindles have grease fittings on the ends then you can use hub # 8-91-05UC1-EZ. If they are...
