When you’re fixing up or upgrading a trailer, the last thing you want is to waste time packing bearings. This Dexter hub-and-drum assembly comes pre-greased and ready to install on 3,500-lb axles with #84 spindles. The inner bearing (L68149) and outer bearing (L44649) are already in place, along with the races, grease seal, cap, and lug nuts. Just slide it on and torque it down — no messy prep work needed.
Whether you’re running electric or hydraulic drum brakes, this 10" diameter x 2-1/4" wide hub-and-drum gives your shoes a solid surface to bite against for steady braking. Dexter builds it from sturdy iron for long-term reliability, and the 5 on 5-1/2" bolt pattern fits standard trailer wheels from 13" to 15".
The bearing setup is a proven combination for 3,500-lb axles — L68149 inner (1.378" ID) and L44649 outer (1.063" ID) bearings with matching races and a 58846 seal (1.719" ID, 2.565" OD). Each hub supports up to 1,750 lbs, giving you balanced load capacity across the axle. The grease cap flange diameter of 1.988" provides a snug seal to keep grease in and grit out.
If you’re updating an older trailer or converting from idler hubs to brakes, this Dexter assembly makes it straightforward. It works with 10" brake assemblies, installs on standard 4-bolt brake flanges, and maintains the same hub face dimensions as idler hubs — so your wheel placement stays the same after the upgrade.
Dexter’s iron construction and consistent quality make this a dependable choice for both fresh builds and long-term replacements. With all key components included and the assembly prepped for quick installation, you get a strong, ready-to-roll hub that’s built to perform trip after trip.
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"

The brakes work great! Wish I had Installed brakes on my utility trailer a long time ago. I move a small compact tractor with my trailer. With the brakes installed on my trailer, driving on the road at highway speeds is much safer now. I can stop in a normal distance, where before it was a bit dangerous. Love the performance of them! Thanks for the information you provided which enabled me to figure out what I needed!

The Dexter parts are working great so far! Although I only used the trailer twice for about 450 miles total. Ive always had good service from etrailer. Thank you for the follow up, I appreciate it.
