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"

Best price and fast shipping! Etrailer.com is my first choice for anything I can get for my trailers. The hubs I got are of great quality and fit perfectly.

Perfect! Hubs held up all through waterfowl and fishing season. Tried to too-off withe grease and they are still full.

I just recently purchased a hub kit from etrailer it come with the hub bearings and the race and the cap it took less than ten minutes to install I would recommend this product to everyone the cost is half what the neighborhood hardware store I plan on using this company in future

Wonderful installation was quick and easy

- 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

The hub kits and bearings are still doing great. Thanks again

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...

Customer service was excellent. Everything I ordered came in 3days. I will buy from etrailer again.

All the parts are a year old and everything is fine. Great company to work with

I needed to replace a hub on my trailer. This pre-packed unit was very easy to install! Shipping got it to me quickly and finding the proper part was very easy on etrailer.com.

- AKIHUB-440-2-EZ-1K

I contacted etrailer with a question regarding a very old small boat trailer. My customer service rep, Jane S, was able to determine my trailer need a diffrent complete Hub/bearings kit than I had intended to order! She determined the one I mentioned to her was slightly larger, and would do damage to the spindles over time! I ordered, then recieved an additonal email from Jane S advising she was able to get the order shipped to me within two days! etrailer is my go to source from this date forward!

Good products, made my project easy. Custom built tow dolly for my Classic Mini

- 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.

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

- 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.

- AKIHUB-440-2-EZ-1K

This is THE way to go. So much easier and cleaner than trying to clean, replace, repack bearings and races from scratch. I will never do it any other way!

- AKIHUB-440-2-EZ-1K

Wheel, hub, and axle products ordered for a utility trailer. Standard free shipping was two days to my door. Everything packed together in one sturdy box for easy handling. Nice!

- AKIHUB-440-2-EZ-1K

The products were received in a timely manner, I was glad to get them as quickly as I did. The products, trailer tires, rims and fender was all of good quality and look forward of them lasting a long time. Thank you very much.

- AKIHUB-440-2-EZ-1K

Part showed up within 4 days of ordering into Canada. I had to drill and install a grease fitting as the replacement unit did not have a re-greasing feature required for the power rake.

- AKIHUB-440-2-EZ-1K

  • Replacement Hub Assembly Needed for 4,800 lb 1992 Ranger Trail Tandem Axle Trailer
    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. Since your 1992 Ranger Trail is a tandem axle trailer rated for 4,800 lbs this indicates that you have 2 axles rated at 2,000 lbs. For a replacement hub we have a few different options and it all depends on what bearings your trailer uses as well as what bolt pattern you have: 4 on 4" Bolt...

  • 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...

  • Replacing Hubs and Leaf Springs on a Small Utility Trailer
    We can definitely get you the parts needed to get your Lowes Trailer up and running, but there are a few things you will need to do to confirm the following parts will fit. First, you will need to determine the bolt pattern of your wheels. I linked an article that assists with this process. If you have a five bolt pattern, I have found that Option 3 in the article is the easiest to use. Second, you will need to remove one of the hubs to get access to the bearings. There are usually...

  • Recommended Hubs for a 1 Inch Spindle
    With a 1 inch spindle, you will need to use a spindle that has the inner and outer bearing # L44643. With that being said, we do have the etrailer.com # AKIHUB-545-2-EZ-1K that will use a 5 on 4 1/2 bolt pattern, or the # AKIHUB-440-2-EZ-1K that will have a 4 on 4 bolt pattern. Both of these option come pre-greased and include the lug nuts and grease caps.

    There are 4 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.

  • What Wheel Bearing Fits a Timken 07204 Race With a 1 Inch Axle
    From what I could find, the Timken 07204 Race has an outer diameter of 2.047 inches. The race that come with # DL21792 would have an outer diameter of 1.980 inches. This would be the closest option we have available. I can suggest a few replacement hubs that fit the 1 inch axle, however. If your wheels have a 5 on 4 1/2 bolt pattern, you would need either # AKHD-545-2-1K or # AKIHUB-545-2-1K. If you have a 4 on 4 bolt pattern, you would need # AKIHUB-440-2-EZ-1K. You can verify the bolt...
