Your old drum is worn and the brakes start grabbing or pulsing. You install this 10" hub and drum with a 5 on 4-1/2 bolt pattern. Pre-greased bearings and a setup that matches your 3,500 lb axle give you smooth braking again.
Designed for standard 3,500 lb axle spindles, this hub and drum works with many utility and cargo trailers. Matching your bearing sizes is the easiest way to confirm it will fit your setup.
The hub and drum are combined into one assembly, so you are replacing both at the same time. This ensures the braking surface and bearing surfaces work together correctly.
Bearings come packed with grease and races are already installed, reducing prep work and helping ensure proper lubrication during installation.
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.
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.)
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.)
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.

Hi, everyone. Steve here with etrailer.com. Today, we're looking at our Terran Industries trailer hub and drum assembly. This is for 3,500-pound axles. It's a 10-inch diameter drum and it features a five on four and a half inch lug pattern. Now, this fits most standard trailer axle setups.
The brake compatibility works with electric or hydraulic drum brake systems. It's a 10-inch brake drum assembly and that provides the surface for the brake shoes to grip the inside of this drum. And again, it's a five on four and a half inch lug pattern. And with an odd number like this, they want you to measure from the center of one stud directly in between two of the other studs, and that's where that four and a half inch comes into play. Now, you can check the product page and you can go from stud to stud and get that measurement, and we can explain that on the page better in depth.
Everything comes pre-grease as far as that inner bearing. That's a 68149 bearing number, and the seal, excuse me. And then, of course, your outer bearing here is a L 44649. You have a cap here. That way, if you have a grease zerk, you can pop that rubber plug out and reach the grease zerk.
Just make sure that you are packing this bearing and putting grease in there before you take off. And then, of course, you got five new lug nuts for the assembly as well. Well, folks, that is gonna wrap it up for our quick look together at this Terran Industries trailer hub and drum assembly. I'm Steven. Thanks for watching.
