Features to know about

Skip the Messy Bearing Work: Pre-Greased and Ready to Install

No need to pack bearings or handle messy grease. The Dexter Trailer Idler Hub Assembly for 3,500-lb axles comes pre-greased and ready to mount. It’s built to slide right onto #84 spindles with both E-Z Lube and standard grease caps included. That means you can finish your hub replacement faster and get back on the road without dealing with extra prep work.

Everything You Need in One Package: Complete Hub Assembly

This hub comes fully equipped so you don’t have to search for matching parts. Inside the box you’ll find bearings (L68149 inner and L44649 outer), races, grease seal (58846), grease cap, wheel bolts, and 1/2" lug nuts. Each part is matched to fit perfectly together for a direct swap on a 3,500-lb axle. It’s a straightforward solution that cuts down on guesswork during installation.

Built Strong for Long-Term Use: Cast Iron Construction

Durability matters when you’re hauling, and the Dexter hub’s cast iron body is made for steady, everyday loads. Each hub carries up to 1,750 lbs, giving solid support for a full 3,500-lb axle pair. The sturdy iron resists wear from road grit and bearing heat so it stays smooth mile after mile.

Simplify Fitment Checks: Clear Specs and Bolt Pattern Guidance

Getting the right bolt circle is easy with this hub’s defined 5 on 5-1/2" pattern. If your wheel measures 3-1/4" from the center of one stud to the next, this is your match. It works with wheels from 13" up to 15" diameter, covering the full range for most standard trailer setups. The hub’s 1.986" grease cap flange diameter keeps it compatible with common accessories like Bearing Buddy protectors for quick maintenance down the line.

Reliable by Design: Precision Bearings and Seal Fit

Dexter pairs each L68149 inner (1.378" ID) and L44649 outer (1.063" ID) bearing with matching L68111 and L44610 races already pressed in place. The 58846 grease seal (1.719" ID, 2.565" OD) helps lock in lubrication and keep contaminants out. Together they create a tight, balanced hub assembly that runs cool and tracks true over long distances.

Determining Bolt Pattern

1. Count the lug holes

Look at the wheel hub or the back of the wheel and count how many lug holes there are(also called bolt holes).

Common configurations include: 4-lug, 5-lug, 6-lug and 8 lug

2a. For even lug counts (4-lug, 6-lug, 8-lug)

Measure from the center of one lug hole directly across to the center of the hole opposite it.

Center to Center
Common configurations: 4 on 4", 6 on 5.5", 8 on 6.5"

2b. For odd lug counts (5-lug)

Measure from the center of one lug hole to the outer edge of the hole directly across (not center-to-center since there's no directly opposite hole).

Center to Outside Edge
Common configurations: 5 on 4.5" (most popular), 5 on 5", 5 on 4.75", 5 on 5.5"

Well, I can't say much about the product itself - seems to be just fine. I can, however, comment on the superb service - our shipment was "upgraded" without even asking. We ordered the part on a Saturday and had it on Wednesday. That's how you keep customer coming back!!

Ordered my part for my pontoon boat that was next go impossible to find anywhere on Monday morning and ups delivered it on wensday afternoon! I haven't put the part on yet due to weather but I'm happy so far!!!

Haven't installed it yet but the construction of the part looks to be very high quality! I am very happy with my order



by:

Was very pleased with the trailer hub .We couldn't find one anywhere else! Would use etrailer.com next time we need anything!



by:

perfect. quick shipping and customer service tops!



by:

No grease zerk. I guess you are expected to use ez-lube axles. No response fro eTrailer about this issue.



by:

i bought this hub to adapt a 30's era Ford spoked wheel to my motocycle sidecar. it fits the wheel perfectly. it will take a bit a creativity to match it to my axle, but i knew that would be needed when i ordered it. it's a good solid piece.



by:

product a Hub and bearings were as expected-New, the bearing cap was thin and crushed when trying to get it to seat but it did finally work the unexpected thing was the fast service it had to be shipped the same day as I called in the order. That means downtime was less!! Thanks and I will be using you again!!



by:

Everything is great. I used thes parts for a year. Many time to the lake and back. Round trip over 500 miles. I really appreciate the quality parts supplied by E trailer

Perfect great product



by:

Product arrived in good condition. Installation was smooth and easy. The only problem that I had, mainly my fault, was installing the dust caps. The fit was extremely tight to the point I bent it up then it would not fit properly. One thing I would suggest to others is to install and tighten as you would normally, then wait a day or two and try to wiggle the rim. If it does pull the cotter pin and tighten again. IF you can not wait then do check them after the first usage.



by:

I was really disappointed that the Dexter Hub included wheel bearings made in China, they were poorly constructed and luckily I kept my "made in Mexico" wheel bearings and installed those instead!



by:

I always go to etrailer.com for all my trailer parts. Fast easy ordering and fast shipping help me get my customers back on the road quicker. The price is right and the parts are quality!

At the time I ordered these, I was new to re-doing breaks. I had never done anything like it before. I did my best research. However, I still ordered the wrong parts for my trailer. George and Tamera were extremely helpful in their research! They went out of their way to help me get what I needed. After watching the videos and getting greasy, the job was complete. I may have made mistakes along the way, and I really should have called first, but in the end, my trailer works great.

My trailer - 3 years later - still has no issues and has over 10,000 miles on it pulling my quads.

I have been a satisfied customer since 2015.

Hubs worked great...now my trailer has the same bolt pattern as my Jeep.

This is an exact replacement for the hub that had been ruined on my 23' Donzi boat trailer. It was shipped extremely quickly and I installed it this afternoon - ready to roll again!

  • Why Cant You Run 16 or 17 Trailer Wheels On Trailer with 3,500 Lb Axle
    The limiting factor for trailer wheel size is going to be either clearance or the hub. It's pretty obvious why you'd run into clearance issues if you don't have room but the hub is not so obvious. The reason there is a limitation here has to do with surface area on the hub and the contact it makes with the wheel. This is why all trailer hubs have a wheel size rating. There is also a concern with bolt pattern and the lack-there-of larger patterns on these smaller hubs. The Dexter Trailer...

    The elements that would need to match up are the inner and outer bearing reference number, the capacity and the bolt pattern. The 5 on 5-1/2 bolt pattern idler hubs we offer use a L68149 inner and L44649 outer bearing. Your existing bearings should have the bearing reference numbers stamped on the bearing cages. If not, measure the surfaces on the spindle where the inner and outer bearings ride. The spindle at the inner should be about 1.378 inches in diameter and 1.063 at the outer....

  • How to Measure a Hub or Wheel for the Bolt Pattern
    If a hub or wheel has an odd number of holes/studs then you would measure from the center of one hole to the center point between the 2 holes across from it. If it had an even number you would measure center to center across the hub. If you measure from the center of one hole to the center of the hole next to it and you get 3-1/4 inches then it would be a 5 on 5-1/2 bolt pattern. Vehicle wheels can be different that trailer wheels and hubs and the offset of the wheels are usually different...

    Hey Matthew. From the information you gave me, what I found was a 3,500lb axle rating hub from Dexter # 84555UC1. Unfortunately, I can't guarantee this is the correct hub for you. I recommend seeing what bearings are in your current hub, this part works with # L68149 inner and # L44649 outer bearings, and a 5 on 5-1/2" bolt pattern and works with a #84 spindle. If you can provide me with the bearing numbers that you'll find stamped on the outer ring of the bearing (inner & outer), Bolt...

  • How To Pick out a Replacement Hub For a Boat Trailer
    Until you can verify that the hub on your trailer is a Trailer Hub Assembly # 84555UC1 I cannot recommend you go ahead and purchase this hub as a replacement. Unless the trailer you have currently has a hub problem you really wouldn't need to worry about having a back up for the 1 hour drive with the trailer back to your home.

  • How to Determine the Correct Replacement Trailer Idler Hub
    To determine the correct hub for your trailer you will want to go by the inner and outer bearing numbers stamped into the metal of the bearings. With these numbers I can determine which hub is a correct fit. Hub # 84555UC1 uses inner bearing # L68149 and outer bearing # L44649. The inner bearing # L68149 has an inner diameter of 1.378 inches. Outer bearing # L44649 has an inner diameter of 1.063 inches. Bearing measurements are in decimals and go to the thousandth of an inch because they...

    The Dexter Trailer Idler Hub Assembly # 84555UC1 referenced in your question is designed for 3,500 pound axles and works with 13 inch to 15 inch wheels, like you mentioned. The potential problem with going to a larger 17 inch wheel is that there won't be enough surface area on the hub to safely support a wheel of that size. This can cause major issues if you were to hit a curb or other object in the road with the trailer, as this lack of support from the hub can easily lead to the wheel...

Aside from that the Trailer Hub and Drum Assembly # 84557UC3 and the # 84555UC1 would work well since the bearing numbers match what you have as well as the bolt pattern. Just so we're both on the same page, offset is the distance the centerline of the wheel is from portion of the...
