No packing bearings or messy cleanup here. This Trailer Idler Hub Assembly for 3,500-lb axles comes pre-greased with lithium complex, multipurpose grease so it’s ready to go right out of the box. Slide it onto your #84 spindle, torque the 1/2" wheel studs, and you’re set. Whether you’re doing a quick swap in the driveway or keeping it as a spare for roadside repairs, having everything pre-assembled saves time and hassle.
The hub is built from sturdy iron with a zinc-enriched paint finish that helps protect against corrosion and wear over time. It’s QAI and CSA certified, giving you confidence it meets quality standards for performance and safety. Each hub supports up to 1,750 lbs, making it dependable for steady towing mile after mile.
No need to track down extra parts. The kit includes inner bearing L68149 (1.378" inner diameter), outer bearing L44649 (1.063" inner diameter), races (L68111 and L44610), grease seal 58846 (1.719" I.D., 2.565" O.D.), grease cap with 1.988" flange diameter, and lug nuts. It’s a full package designed to fit standard 3,500-lb axles from most manufacturers including Dexter, Lippert (LCI), and AL-KO.
This hub fits 14-1/2", 15", 16", and 16-1/2" wheels with a 6 on 5-1/2" bolt pattern, covering many popular trailer setups. The evenly spaced pattern keeps wheels balanced for consistent performance—ideal when you need reliable alignment and smooth rolling on long hauls or heavy loads.
With pre-installed races, the hub sets up easily without hammering or special tools. Just mount it and go. The zinc-enriched coating helps fend off rust from wet or salty roads, while the pre-greased bearings keep everything turning smoothly for the long haul—perfect for keeping a trailer rolling without downtime.
To ensure you select the correct hub or wheel, it’s important to measure your trailer’s bolt pattern accurately. The following diagrams show how to measure both even and odd bolt patterns:
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.
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).
Common configurations: 5 on 4.5" (most popular), 5 on 5", 5 on 4.75", 5 on 5.5"

Quality Product at an Economical Price, with the most incredible customer service representative named Hannah!!! Could not be more pleased!!!
Excellent service, my parts arrived as premised.
Exactly what I needed. Great customer service and prompt shipping.
Perfect fit . Great price and fast shipping.Went from a 5 x 4.5 to a 6 x 5.5 bolt pattern so I could fit a FJ Cruiser wheel on a motorcycle trailer to match my vehicle..Thanks so much for your help and service.
etrailer as been a great help finding the right Hub to fit the wheel and tire I have. I didn't have any trouble with returning my 1st set of hubs. I haven't had a chance to see their products at work with my AG. sprayer trailer. Thank you for your help.
Easy money to install. I use stock 4runner wheels and tires on my trailer now.
Nicely made. Good quality. They look like they’ll last for the life of the trailer as long as I maintain the maintenance

Great! Nothing but good to say about them.
I wanted to have the same bolt pattern on my trailer as my truck. When I needed a new rim for my trailer I bought 2 and made the switch. This will help save space and weight not needing an another spare tire. Web site had all the info you need, making it very easy to know what you are getting. shipment was on time. just add grease at install and you are ready to go.
I was very pleased with the quality, fit and ease of install. Would highly recommend.
We are a very small agricultural manufacturing company, all our implements that require axle,spindles,tires,or wheels will be bought at etrailer. FREE SHIPPING!!! BIG SAVINGS!! GOOD EASY WEBSITE.
First time I ordered hub and spindle so they would match up sent the wrong hub for the spindle so reorder hub was back ordered for months I gave and got a refund but the whole axle I was working on I scraped and just a used axle so the new spindle was worthless.
Fit as expected, was a bit challenging as the trailer that came with the had the hubs rusted to the wheel, nothings would separate them, heat, cold nothing worked. Took the whole thing of and ordered the hub by micrometer measurements of the spindle. Fortunately etrailer provides these measurements.
I knew this rig was a labor of love from the start
I ordered two wheel hubs with bearing last year for my trailer. Parts were easy to locate on your web sight, ordering was easy and shipment was very rapid. The parts are quality parts and have performed well for the past year. Very pleased with my purchase.
Good product. But the shipping was delayed at no fault of etrailer. But it took a long time to even get a tracking number. Didn't get a tracking number untill I contacted etrailer about it
These hubs installed perfectly on my utility trailer, and now it runs 17" 6-lug wheels that match my 4x4 (after fabricating a centering hub for the hub-centric wheels). With the addition of Bearing Buddies (also from etrailer) it's a great setup. Very happy with the product quality and delivery, etrailer is tops!
Excellent Hub Assembly that comes ready to slide onto the spindle. Purchased these hubs for a Trailer here in Canada. Even with the crazy exchange rate and shipping. It was still a better deal.

Product still performing well. No issues what so ever.
Hub fits wheels perfectly. Hub fits axel perfectly! I’m thoroughly pleased and happy! Great customer service still exists! Thank You!
great quality was very convenient to have a complete assembly pre lubed was like having a helper in my own show get it ready.
Awesome hubs. Good quality and pre-assembled is completely worth it.
Quick and simple way to replace worn be arings!
Haven't had a chance to install yet. Should do it this week. Delivery was sufficient and timely. Really like the idea of the kit. Didn't have to research bearings, races and seals with all the hardware.
I’ve been looking for this hub for a few months now, and when I saw it online, I spent like two hours checking and rechecking it was the one I needed. The good thing is that the description on etrailer.com is detailed. Frankly now that I think about it, I spent more time making sure it was the correct hub, than what I did putting them on. They were pre greased and fit perfectly. The shipping was quick too, I received them three days after I placed my order. Thank you, etrailer.com for having what I needed.
I bought a 5'x10' utility trailer that had some jeep wheels mounted with some wheel spacers with the 5x4.5 bolt pattern. I had some 6 lug wheels that matched my truck and wanted to switch the trailer over to 6x5.5 pattern and eliminate the wheel spacers. I followed the how to in the faq section on how to measure my axle spindle for correct hub/hub bearing replacement. These hubs were exactly what I needed and mounted just fine. It was awesome that the races, bearings, seals, and grease were pre-installed. Took about 20 minutes per side from old wheels and tires on the ground to new wheels and tires on the ground ready to roll. Very nice all in one product. The quality of the parts looks and feels great. Well worth the money. I would recommend these and etrailer.com to anyone needing parts to maintain your trailer. Thanks!
I patiently waited through about 3 1/2 months of supply delays, and the hubs have arrived. Pre-lubed, with shipping covers, was a nice touch. Most difficult was removing and re-installing the axle cotter pin. Otherwise, maybe 7 minutes install time per hub. Not punching out the bearing as it slides onto the stub is only other point of concern. Dust caps are a bit hard to get set. If I can, I'll include photos of previous axles, new install, and finished.

These have made a world of difference compared to the old ones. Even looks better. All 4 wheels the same, lug nuts all same, not fighting rust. Should have bought a fifth wheel for the spare, but whatever. Glad I got them. I will remember them ifwhen I get to my next trailer build. Now, what about converting trailer house axles to highway hubs, hmm.
Great product. Allowed us to put 16 inch rims on our trailer for smoother roll.

Not so good. I had to replace them already with sealed bearings and new calipers and rotors. They couldn’t hold up to the salt water environment
