E-Z Lube-Compatible Assembly for Simple Lubrication

The grease cap on this hub-and-drum assembly 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"

Grease cap damaged/unusable and this like dexter item dimensions are all different. So long as the wheels line up and the drum contacts the brakes pad properly I’ll let it ride. And the like new but missing parts drum is damaged and the bearing race is not seated

trailer hub arrived with something that appears to be sand all throughout the assembly. I'm sure it is obvious what sand will do to bearing

I am not sure what happened there. It is the first time I have seen that happen. Customer Service will be in touch with you.



by:

This hub and drum assembly was very easy to install. The parts came pre-assembled and pre-greased. The kit came with all the necessary hardware and even included extra hardware depending on the axle type. Fast shipping and straightforward customer service. Very much appreciated.



by:

Everything I needed I found at etrailer and everything fit perfectly!! Customer service was excellent!!



by:

Five star. shipping was slow. Product was great 14 K 14 plies under 2000 pounds independent suspension. Low fast and sassy. Yep that’s how I build them.



by:

Everybody is completely smashed to pieces. I bought a kit for my store but can not put smashed torn apart boxes on the shelf. Why were these shipped in the box that is to be put on the shelf? Adhesive shipping labels veering descriptions and part quantities.

I am sorry that the hub assemblies were delivered this way. I will share this with our shipping department and will have our Customer Service team reach out to you.



by:

Outer bearing #14125A was damaged. Notified Davine at etrailer and emailed her a picture of the damaged bearing. Currently awaiting a response. Everything else in the package was ok.



by:

Thanks so much etrailer for making me feel so much better/safer about carrying heavier loads in my trailer. Katrina also went the extra mile when it came to customer service and patience with my order. I had 15" six lug hub and drum assembly which held all I could load on them, like I said I just did not feel safe so I went with this hub and drum assembly which came with all necessary items for the install, and it allowed me to put 16" tires with a heavier weight rating. Very pleased.



by:

So far so good. Good customer service, boxes were not damaged and arrived within a couple days. Genuine dexter parts and they also helped swapped a backordered part.



by:

The one thing I would change is us FEDEX and not UPS. Packing was ripped open. happens every time I get anything from UPS



by:

Great product and exact replacement for our 42ft Keystone Montana High Country 375FL.
Fast shipping and correct part is extremely important as we are full time RVers and with limited time.
I've ordered several items over the years and always received great service.



by:

Very fast shipping.

These guy's at etrailer are hard to beat! Customer care is over the top. That's why Allison Creek does business with etrailer.



by:

Parts are good. Service sucks! When I ordered and paid for four of these they were in stock and was to be at my door in three days. Four days later they said they were out of stock and would take another two weeks before they would have them in. Don't order unless you have about three weeks!



by:

As advertised



by:

Worked great for the upgraded wheels I put on my Grand Design 5th wheel!!



by:

As always, great service and knowledgeable assistance.



by:

Quinn has been very helpful in making sure parts are delivered on time



by:

good product for the money



by:

The pre packed bearing kit saves time, easy to install. No concerns



by:

I ordered this as spare hub assembly for my 5th Wheel RV. We are leaving next month on a 5000+ mile, 3 month trip. I figure if I have a bearing go bad I can swap out the whole hub and be back on the road in no time. The hub is the same Dexter hub that I have on my rig now.
Shipping was fast and free, Helen was great, helping me find the part numbers of some of the other accessories that I needed to have spares of. Speaking of shipping I had checked other places for the hub and while the price was similar the freight charges were half the price of the hub. I will definitely be giving trailer my business going forward.

I havent had to use this Hub as of yet but, just having with me when we travel is comforting.



by:

Perfect replacement for the factor hubs. Thought I ordered the easy grease hub. A pre-greased one was shipped...NO PROBLEM!!! One less thing I had to do to install. Etrailer will continue to have my business.



by:

This is exactly what I need for an on-the-road repair! I ordered a second because I had a wheel-lug issue on I-95, and this kit got me rolling again! Thanks for offering a very complete setup at a great price. Finally, the free shipping is EXCELLENT! With some vendors "free shipping" means "you will receive it sometime next year." Not etrailer.com! Thanks!

SECOND TIME IVE ORDER A HUB ASSEMBLY FOR MY JOB CAME IN EARILER THAN EXPECT & PACKEGED NICELY & EVERYTHING WAS CORRECT!!!!



by:

I love ordering from etrailer. They have a great team. The brake assemblies and hubs arrived on time and the installation was easy. The only negative was one of the drum assemblies arrived with a crushed seal and the outer bearing cage was bent up. I know etrailer would have sent replacement parts but do to time constraints I made a trip to our local trailer parts store. $20 later and a little time I was back to work. There was no damage to the box. The bag with the bearings and seal in it got to where it could get damaged by the weight of the drum.

    The only difference between the Dexter Trailer Hub and Drum Assembly # 42866UC3-EZ and the Dexter Trailer Hub and Drum Assembly # 42866UC3 is that # 42866UC3-EZ is designed to be used with #42 E-Z lube spindles and # 42866UC3 is meant for regular #42 spindles.

    The highest capacity Timbren Axle Less system is the 7k part # TASR7KS01 which can be used on a tandem axle trailer. For brake drums you'd then want the part # 42866UC3-EZ which fits the spindles of the Timbren. Then for a 14k surge brake actuator for drum brakes you'd want the part # T4836600. Lastly you'd need a tandem brake line kit like the part # 20TA-BLKIT.

    Thank you for providing that information. Since you have a 6,000 lb axle we can narrow down the parts. However, you will still need to identify your grease seal. Unfortunately, the serial number won't help in this case since Axis Products, Inc. was sold in 2015 so no information is available. For brakes you can use the # AKEBRK-7-SA if you need electric brakes or the # AKFBBRK-7 for hydraulic brakes.

And we can get you parts for your trailer, though the issue is that there isn't an available hub for your spindle due to what you mentioned - the uncommon 501349 bearing, which is for older agricultural spindles. There also isn't a 7,000 lb-rated hub with a 6 on 5-1/2" bolt pattern to go with your 7k-rated Dexter Nev-R-Adjust Electric Trailer Brake Assembly # 23-464 and # 23-465.

  • Replacement 7,000LB Trailer Axle For a 89 Hub Face and 74 Spring Center
    The Timbren Axle-Less Trailer Suspension System # TASR7KS01 is the only axle we have that replaces your 7K with 89" hub face and 74" spring center. Our heaviest standard axle that matches your dimensions is only 6,000LBS # 8327830. The Timbren will use the same style Hub # 42866UC3-EZ and Brake Assemblies # 23-464-465 that you likely already have with your current axle. If your trailer is a tandem axle you are able to replace both axles with 2 of the Timbren systems listed above.

In order to get the most accurate measurement ,the wheels of the trailer should be off the ground since the springs stretch when weight is applied.

  • Why Does Trailer Have More Weight Capacity Than Axle Capacity
    Great question. So the difference is the weight of the axles not counting against their own capacities. So the wheels/tire/hubs etc. are decently heavy but the axle's capacity does not factor that weight. This is why sometimes you'll see trailers have more weight capacity than axle capacity.
