E-Z Lube and Easy Grease-Compatible Assembly 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"

Average Customer Rating:  4.6 out of 5 stars   (25 Customer Reviews)

Hub is designed for use on trailer idler axles. Fits 3.5K Dexter E-Z Lube and etrailer Easy Grease axles with #84 spindles. Inner bearing (L68149) and race, outer bearing (L44649) and race, grease seal, grease cap, and lug nuts included.


Straight forward. Product was exactly as described. Bearings, races and seals were already installed.


Always good selection and good service from Etrailer. I got my wheel hubs easily replaced with this product.


Quick two day delivery! Good quality part (made in China) and an easy, cost effective way to replace damaged or worn out bearings and races. Just add grease and press in the seal! Just completed a 500+ mile trip with trailer and street bike in tow and had no issues.

After some 3000 highway miles and a few rough country roads carrying motorcycles and ATVs, only issue has been a lost dust cap.
Tom S - 11/02/2020


Everything went together easily and fit just like it should. No issues on a 600 mile round trip at interstate speeds towing 5000 pounds on a dual axle trailer.

These worked just fine while on the trailer and still look new when I replaced them recently with a set of drum brakes.
Christopher F - 02/06/2021


These hubs worked perfectly. I purchased to replace the originals that came on a Carson flatbed utility trailer. Fit perfect. Installed easily. They were on my doorstep in two days. etrailer will be my go to shop for any trailer needs.


I didn't know exactly what I needed when I spoke to the sales person, I felt so relieved. They were very informative and polite. I am very satisfied with the product and service.I have recommended etrailer to my friends and I will be purchasing more products from them.


Perfect! I'm extremely pleased with this purchase and couldn't have gone through a better company. Thank you


Always happy with etrailer products, speedy shipping, customer service and great prices!!

Thank you


Exactly as pictured. I can't comment on fitment as I did not buy it to use at this time but rather as a spare to have with me on a long trip. I opened it and checked everything and it appears well made. The only reason for four stars and not five is the bearings are not pre-loaded with grease but rather shipped dry. This is not a big deal as I always have the grease gun with me but I would have preferred them to have had grease in them and sealed for rust protection but I'll just grease them and put them in a zip lock bag, I''ll also put a little grease inside the Hub for rust protection.

They are kind of like a spare tire, you dont use it or need it until you do. Mine is packed and sealed up ready for the roadside fix I hope never comes.
Robert - 04/22/2019


I had the opportunity to deal with a few sales consultants on an issue I had with a broken hub. After a few phone calls and emails, they were able to send me the parts that I wanted. I sent the consultants multiple photographs with measurements. These photographs were uploaded to my account for future reference. I was very pleased with the experience, as I had never utilized etrailer prior to this order. I highly recommend etrailer!


1 of 4 bearings blew out, had to replace hub. Replaced all bearing after that. Great price, you get what you pay for.


For where I live this hub was very difficult to find, I found it on your website very easily and the price was great. I ordered your item ground shipping and you went above that and sent it speedily. I will be ordering from you again for parts for my trailer. I had an amazing experience with your business. Thank you...


Great price, super fast delivery, and everything needed to repair my trailer worked perfectly!


Item shipped quickly, very complete, fit well, easy install.


Fit and works like factory

  • Replacement Trailer Hubs with Bearings L68149 and L44649 that is Pre-Greased
    For the correct hub/drum you'd want the part # AKHD-550-35-K which comes with the bearings you said you needed as well is pre-greased. If you were wanting an idler hub instead you'd want the part # AKIHUB-550-35-EZ-K.

  • Timbren 3500 lb Rated Axle-Less Suspension and Compatible Idler Hub for Home Made Trailer
    The 3500 lb Timbren Axle-Less suspension kit # ASR3500S05 would be a good choice. The spindles provided with the # ASR3500S05 would indeed be compatible with the bearing set provided with the # AKIHUB-550-35-K idler hub, but since the Timbren Axle-Less suspension you've chosen features E-Z lube spindles, you'd want to go with # AKIHUB-550-35-EZ-K which provides the E-Z lube compatible dust caps with removable plugs so you can easily access the grease zerk without needing to remove the entire...

  • Replacement Hubs and U-Bolt Kit for 3,500 Pound Lippert Axle # LC35212150
    From my research your axle is a 3,500 pound, 2-3/8 inch diameter axle and since you have a 5 on 5 bolt pattern you likely have bearings # L44649 and # L68149. You'll want to verify this is correct with your current bearings. If this is the case for a hub and drum assembly I recommend # AKHD-550-35-EZ-K which is for E-Z Lube axles with a zerk fitting. If you have standard axles use # AKHD-550-35-K instead. If you only need idler hubs use # AKIHUB-550-35-EZ-K with E-Z Lube axles and #...

  • Recommended Replacement 3,500 lb Axle for Carson Trailer with 88" Hub-Face and 74" Spring-Center
    We do have a replacement 3,500 lb axle for your Carlson trailer as well as hubs that fit your description. The axles that we carry have an 89" hub-face and 74" spring-center measurements so since the hub-face dimensions are only 1" off of what you measured these will work well for your application. I'm pretty sure that your axle has the 89" hub-face measurement as that is extremely common (and measuring the hub-face is a little difficult) but even if our axle hub-face is 1" wider there...

    There are only 3,500 lb trailer axles that have hubs available with the 5 on 5 inch bolt pattern like with the Easy Grease Trailer Idler Hub Assembly # AKIHUB-550-35-EZ-K so you'd need to go with a 3,500 lb trailer axle if possible or at least install new spindles like with the # TRU74FR.

  • Axle-Less Trailer Suspension Recommendation for a Military Trailer Using 5 on 5" Bolt Pattern Wheels
    The Timbren Axle-Less systems are definitely the way to go and are right where my mind went when I was reading your question. For your application you'll need a system rated for 3,500 lbs. If you need something with a higher weight rating let me know.

    In order to use Jeep wheels with the Timbren Axle-Less Trailer Suspension System you'll need to go with the part # ASR1THDS03 which has a 2,200 lb weight capacity. This can then be used with the Trailer Idler Hub Assembly part # AKIHUB-550-35-EZ-K or the Trailer Hub and Drum Assembly part # AKHD-550-35-EZ-K and Electric Trailer Brake Kit part # AKEBRK-35-SA if you need brakes.
