E-Z Lube Design

The E-Z Lube design of this assembly not only makes lubricating the bearings easy, but it also helps prevent corrosion of the hub. This is because you can lubricate the bearings without the mess of taking apart the entire assembly. 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.


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"

Video Transcript for Dexter Axle Trailer Hubs and Drums - Hub - 84545UC1-EZ Review

Speaker 1: Today I'll be taking a look at the Dexter Trailer Idler Hub Assembly for 3,500 pound EZ-Lube axles, with the 5 on 4 1/2 inch bolt pattern. Now this hub assembly is designed to fit the EZ-Lube trailer Idler axles, and the EZ-Lube axles are the ones that'll have the spindles on the end that have a grease surfening 00:16, that allow you to lubricate your bearings without having to remove the hub. This part will include everything shown here on the table, the hub assembly itself, both the inner and outer bearings, the bearing races, which are pre-installed in the hub, the grease seal, the easy-lube grease cap, the spindle jam nut and nut retainer, and the wheel lug nuts to hold the wheels to your hub.Now the cap that comes with it is an EZ-Lube compatible grease cap, makes lubricating very fast and easy. And as I mentioned, it has a rubber plug that you can . when this is installed, you pull that rubber plug out, and this allows access to that grease surfening on the end of your spindle, allows you to grease your bearings, no need to disassemble the hub.Now the hub is a sturdy iron construction, it is made in the USA. Application again for this is 3,500 pound EZ-Lube trailer axles, with the number 84 spindles.

The wheel size that'll work on this hub is 13" up to 15". The bolt pattern again is a 5 on 4 1/2 inch bolt pattern. The wheel stud diameter is half an inch. Weight capacity on this one assembly is 1,750 pounds, so when one of these is mashed on one end or one side with one on the other side, it'll meet your 3,500 pound axle capacity.Now the bearings that are included, the inner bearing, which is the larger one, is part number L68149, has an inner diameter of 1.378 inches, that goes onto the inner bearing race just like that. The next one is the outer bearing, it's part number L44649, has an inner diameter of 1.063, goes into the bearing race just like that.

Now the bearing race, as we mentioned, are all pre-installed here. A double lip grease seal, it's part number 58846, has an inner diameter of 1.719 inches, outer diameter of 2.565 inches. That'll go in the back here after you put your bearing in there, then you put your seal in there.The grease cap, we mentioned, is the EZ-Lube grease cap, part number 21-41-1, has a flange diameter of 1.986. That goes around the outside here, after you put the bearing in there. The spindle jam nut with the nut retainer, and the 5-1 nut size 1/2 inch by 20, part number X1023R, and those lug nuts are used to hold your wheel to your hub.But that should do it for the review on the Dexter Trailer Idler Hub Assembly for 3,5000 pound EZ-Lube Axles, with the 5 on 4 1/2 inch bolt pattern..

Ordered this hub assembly on a Thursday with standard ground shipping, received it the following Monday, can't beat that. I had questions regarding the grease seal (curios if it was double lipped or not, it is) that came with the assembly and they were quickly answered by the support staff. My only real complaint about the whole ordeal is that I never could get the "EZ" dust cap to seat in the hub so I ended up using my old bearing buddies from the old hubs. All in all though it was a well rounded transaction. 91411

sirs/mams Good afternoon from Seabeck Washington! Your customer service is awesome, this was all due in to Darren and I will be back! I have attached some pics of my application. the spindle was used for an old military trailer, the steering axel is different, as it is not a typical steer axle and is able to rotate 360 degrees. it pivots on a axel spindle and it was sheared off at the base just above the seal area. so i had to cut it out and do a re-install with your replacement and it was a perfect match. Thank you guys again! 672362

I wasn't replacing hubs but rather installing them on new axles (Timbren Axle-less system also purchased here). It was convenient to get the hubs here as I was also purchasing the Timbren system so I knew the setup would work together. Being a novice at working on trailers, these hubs installed without a problem using the instructions provided. I had read several articles on problems with new hubs and the key comments I heard echoed was to be generous with greasing the bearings. It's been a year and I only have about 500 miles on the hubs but everything still sounds good. I use the trailer for pulling my motorcycle so the load has been roughly 1200 pounds. The tires are ST145-R12 trailer tires. 352954


Comments
The hubs are still sound after a year of occasional use. The configuration has worked well for me and still pleased with the results of the products Im using.

  • Which Hubs Do I Need For Timbren Axle-Less Trailer Suspension System With Off Road Tires
    Yes the Timbren Axle-Less Trailer Suspension System # ASR1THDS01 will work with Dexter Trailer Idler Hub Assembly # 84545UC1-EZ. They both use the same bearings and seals, and is confirmed to work together. The idler hub can mount a 13" wheel up to a 17 1/2" wheel, and has a 5 on 4 1/2" bolt pattern for the lugs which are 1/2" in diameter. So if your wheels are 15", have the same bolt pattern and diameter lug nuts it will definitely work. As far as the height of the tire, it will only...

  • Determining Correct Replacement Hubs for Dexter 8-286 Hubs on 2,500 Pound Axle
    I reached out to my contact at Dexter but they are having a hard time pinpointing the exact hubs your trailer is equipped with using the information you provided. The 8-286 number you mentioned actually refers to a 9,000 pound hub, which would certainly be out of place on and likely wouldn't fit your 2,500 pound axle. Are there any other markings on the hub at all that you can give me? If not your only option will be to pull one of the hubs and check for the inner and outer bearing...

    The Dexter 8-283 is an obsolete 2800lb 10 x 1-1/2 inch hub that used a LM67048 inner and a L44649 outer bearing. Unfortunately, we don't have any hubs that would be compatible with the spindles on your axle. Your best bet at this point would be to order a new axle that has spindles that are compatible with modern hubs. We offer a few off-the-shelf axles in standard sizes. In order to see if what we have would work for you, I'd need to know the hub face to hub face dimension and the spring...

Since it sounds like you cannot get to the bearings to record part numbers, you will need to use a dial caliper or similar precise measuring tool to take the measurements.

It is actually easier to replace the entire axle with a new one that has good spindles on both ends. This may even be less costly than having a new spindle welded on by a qualified welder. It will also ensure that both spindles will have the same working lifespan, which would not be the case if only one is...

These two assemblies fit the same spindle as both use Inner Bearing # L68149, Outer Bearing # L44649 and Grease Seal # 58846. Both idler hubs have a 5 on 4-1/2" bolt pattern and are designed to fit 3,500 lb E-Z Lube axles.

  • How to Determine Correct Trailer Wheel Lug Nut Torque for Utility Trailer
    The correct lug nut torque range for any given trailer depends on several factors include the lug diameter, lug nut type and wheel material.

For example, the first listing on the chart, for 1/2-inch studs, coned lug nuts on a 15-inch steel wheel, the correct range is 90- to 120-ft-lbs.

  • How Do I Determine Which Replacement Bearings I Need For a Trailer
    Based on your inner diameter of 1-1/16 (1.063 inches) the replacement trailer hub bearings you need are # L44649. The matching race is # L44610. I highly recommend measuring the bearings and seals with a digital caliper tool to the thousandth of an inch. You would need to remove your hub to obtain. See the diagram to the right. I have included a FAQ and video review for you too.

  • Trailer Hub and Wheel Size Compatibility
    Any hub will have a range of compatible wheel sizes. The idler hub # 84545UC1-EZ you referenced will work with rim diameters from 13-inches to 15-inches. All idler hubs we have for 3500-lb axles work with these same rim diameters. If your 3500-b axle's current hubs now have 13-inch, 14-inch or 14-1/2-inch wheels on them they will be fine with 15s. Do note that moving to a larger wheel/tire will not change the axle, hub or trailer weight capacity but it may well allow your larger tires...

I have included a link to a video that shows how to pack trailer bearings before installation into the hub. You can use a grease like # l11404. We also have a bearing packer, # L70025. I have included a link to a video that shows how it works.

  • Hub Replacement Recommendation Where Races are L6811 and L44610
    Yes, the Trailer Hub Assembly # 84545UC1-EZ that you referenced would be the correct hub for you. Based on the race numbers you listed the bearings that you have are the L68149 and 44649 so the # 84545UC1-EZ would be the correct hub for you as long as your wheels have a 5 on 4-1/2 inch bolt pattern. If you have a different bolt pattern check out the link I attached shows all of the hubs that would install on your spindle. I attached an FAQ on determining bolt patterns for you to check out.
