E-Z Lube-Compatible Hub 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"

AFTER FIVE YEARS IT WAS TIME TO REPLACE THE BRAKES ON MY TRAILER. I TRIED LOCALLY AND THROUGH THE TRAILER FACTORY. LIKE MANY TRAILER FACTORIES THIS ONE HAD NO RECORD KEEPING. THEY COULD NOT GIVE CORRECT PART NUMBERS. IF I DID BUY THROUGH THEM, THE PRICE WAS TWICE THE AMOUNT OF E TRAILER. I CONTACTED E TRAILER AND SPOKE WITH PAT. SHE WAS GREAT. SHE TOLD ME TO MEASURE MY PARTS WITH A MICROMETER AND GIVE HER THE MEASUREMENTS. SHE FOUND THE CORRECT PARTS, THE EXACT PARTS MY TRAILER WAS BUILT WITH. THE ORDER WAS PLACED AND GET THIS, SHIPPED TWO HOURS LATER. I HAD MY PARTS IN THREE DAYS. DID I MENTION THEY INCLUDED THE RACES ALREADY PRESSED INTO THE HUBS/DRUMS, BEARINGS, DUST CAP, AND NEW LUG NUTS. ALL OF THAT WAS EXTRA FROM EVERYBODY ELSE I CHECKED WITH. THANKS E TRAILER

This is the exact replacement part that I needed for a EZ Lube hub with electric brakes. It was easy enough to install. Etrailer has many install videos The drums do not come with a dust seal plug on the brake adjusting hole. I purchased some at the local automotive parts store. These replacement hubs are now on a 13' Scamp Travel Trailer. The original hubs and brakes were shot. Now, I have new hubs, bearings, races, electric brakes on my 13' travel trailer.


Comments
Ten thousand miles on these new brakes. They are working just fine. I adjust them about every three thousand miles. After seven thousand miles, I pulled the brake drums and looked at them. The whole assembly and drum and magnet rubbing surfaces were just fine. I put in new double seals Etrailer sells them after pulling the brake drums. Grease the bearing with the Ez-lube hubs while spinning the wheel until new grease starts to exude. I will buy these again when needed.

What more can one ask for, I needed to turn the old drums and then found these drums on etrailer.com - complete with new bearing and seals and of all things, new lug nuts. For the extra money this was so well worth getting. Now my 2001 Coleman Sante Fe has totally new drums, brake assembly and wiring. The cool thing, they are original dexter parts, not off brand.

I purchased the Dexter Electric Trailer Brake Kit, the Drum assembly, a Draw Tite controller, and the install kit. An upgrade to my newly purchased camper which came with no brakes. All parts were of high quality, well packaged and arrived in excellent condition. Customer support was first class, taking me through the purchase process item by item assuring I had all items necessary for this task. Instructions were good, but I recommend checking the etrailer.com online version for more detail. No issues at all installing the new equipment. High marks for etrailer.com. Performance is very good.

Ordered the products on a Tues. night and they were on my doorstep Fri. afternoon. Excellent product that was a direct replacement on my Chilton snowmobile trailer. Everything fit like a glove with no issues at all. Highly recommend etrailer.com and the Dexter products I purchased which were these hubs and the Dexter 7 x 1-1/4 brake assemblies.

The construction of the drums seem decent enough however a bit inferior compared to my original ones as the dimensions were not as exactly as advertised. I was not happy at all with the way they seem to fit. There was one half inch gap between the drum and the brake back assembly, I tried calling and explaining to customer service however the girl on phone was rude and tried to tell me that it's just the way it fits and it was not going to be the same as the original one. I wanted to return them for a refund but the shipping cost will be the cost of the purchase price as I live in Canada. This the last thing I'll ever buy from this site , I'd rather pay my local RV dealer extra 100 bucks and have the peice of mind that I'll get the correct part.

I recently ordered and received an extremely hard to find brake hub from etrailer.com. Unfortunately, I didn't measure it correctly and ordered the wrong part.

Now a lifelong customer..

The product arrived in very quickly, 2 days even though I requested a minor change to the order. The brake assembly and hub and drum assembly were perfect fits. I subtracted 1 star because the 2 brake assemblies were "loose" in the same box with the hubs which left the brake assembly magnets loose. I was able to find the magnet clip in the corner of the box under the flap. Otherwise I would have had to reorder. Great customer service was hurt by very poor packaging. However, I wholeheartedly recommend this product. No instructions were included, but there are several helpful videos on etrailers web site.

  • Why Can't 13 Inch Wheels Fit Trailer Hubs Designed for 12 Inch Wheels
    The issue with using a 13 inch wheel on the Dexter Trailer Hub and Drum Assembly for 2,000-lb E-Z Lube Axles # 8-257-5UC3-EZ, which you correctly noted is for 8 inch to 12 inch wheels, is that hubs of that size do not have a large enough flange diameter in order to to provide the necessary side-to-side support for a larger 13 inch wheel. Technically it may fit but it would not be recommended. The best option is to go with smaller 12 inch wheels and tires. For a 5 on 4-1/2" bolt pattern,...

  • Parts Needed to Add Electric Drum Brakes to a 2,200 Pound Pop-up Camper
    Your trailer likely uses L44649 inner and outer bearings for the hub. You could pull off a hub and check the numbers on the sides of the bearings to be sure. They will have to come off anyway to install the brakes. For L44649 inner and outer bearings and a 4 on 4 bolt pattern you can use # 8-173-16UC3 or, if you have EZ lube axles with the grease fitting at the ends then use # 8-173-16UC3-EZ.

    Your 8257 hubs are # 8-257-5UC3-EZ. If you'd like to verify these check your bearing numbers. They should be # L44649 for both inner and outer. The hub and drum assembly is a 5 on 4-1/2 bolt pattern for 2,000 pound axles. It includes the bearings, races, seal, grease cap, wheel bolts and lug nuts. For replacement brakes use # AKEBRK-2. This includes both left and right hand side brake assemblies. They're marked as such because they are side specific.

    Your 2001 Jayco Eagle 12 SO pop-up camper very likely has a 10" diameter x 2-1/4" wide hub and drum assembly, though you need to check to verify that is the case before ordering a brake assembly. If it does, I recommend Electric Trailer Brake Kit # AKEBRK-35-SA, which are self-adjusting brakes that are designed to work with 3,500 lb axles.

    If you currently have idler hubs on your Timbren suspension you will need to change them to hub/drums in order to install brakes on the trailer.

  • Can 7 Inch Electric Trailer Brakes Be Used on a 3500 Pound Trailer Axle
    With the right size hub and drum assembly you could technically use 7 inch brakes on anything. The problem is that 7 inch brakes are rated too low for a 3500 pound axle. They are only rated up to 2500 pounds. The other issue is that the hub/drums that are associated with 7 inch brakes are not likely going to fit the spindles on a 3500 pound axle because the bearings will not be the right size. On 3500 pound axles you will use 10 x 2-1/4 inch brakes. I have included a link to all of the...

With that info I can help you figure out what you need.
