If a trailer hub suffers damage, corrosion or improper installment, it probably comes as no surprise that your trailer, vehicle and load are at risk of serious damage. You do not want a wheel disconnecting from your trailer while you are driving down the road. As a result, routine maintenance is important for each trailer hub assembly.

How to Measure Trailer Hub Size
Trailer hub assemblies work with different load capacities, bolt patterns, tire sizes, bearings, and axle designs. If you do not know your trailer’s hub size, there are a few methods that can help you find out. Trailer hub sizes are determined by the size and shape of the spindles on your trailer’s axles. Once you take off the wheel and trailer hub assembly, look at the spindle. You may have either a tapered or a straight spindle. Tapered spindles work with trailer hubs that contain two different sized bearings. Straight spindles have the same diameter at the bearing locations. If you have a tapered spindle, you need to make two measurements whereas you’ll only need one measurement for a straight spindle. If you have a digital caliper, place it on the spindle at the bearing locations and measure the diameter. The resulting number is the diameter of the spindle and the inner diameter of the bearings used in the hub. These diameters can be used to determine the bearing and hub sizes required for your trailer. You can also use a flexible measuring tape to measure the circumference of the spindle at the bearing locations, and this number can be used to find your trailer’s hub size as well. Finally, you can remove the old bearings from your trailer hub assembly and find the part numbers. These part numbers can be used to determine the hub size your trailer requires.
How to Replace Trailer Hubs
Replacing the hub assemblies on your trailer is pretty simple so long as you are armed with the necessary replacement parts, a jack, a hammer, pliers, wrench and a few other basic tools. Remove the lug nuts to take the wheel off your trailer. Locate and remove the cotter pin from the end of the spindle using a pair of pliers. Unscrew the castle nut and pull the existing hub off the trailer spindle and axle. Unless your trailer hub assembly is already pre-greased, it will be helpful to spread a thin coating of grease on the inside of the new hub before sliding it onto the spindle and axle. Following the trailer hub removal process in reverse to successfully install your new trailer hub replacement parts and assembly.
How to Grease a Trailer Hub
Cleaning and greasing your trailer hub assembly is part of regular maintenance. If your trailer hub parts are not damaged and just in need of cleaning, soak the bearings and spindle nut in kerosene for ten minutes. Clean the inner and outer races with a rag while the bearings and spindle nut are soaking. It is also recommended that you replace the grease seal when conducting this normal maintenance. After ten minutes, take the bearings and spindle nut out of the kerosene bath, spray them with brake cleaner and wipe them down with a rag. Next, you will want to repack the bearings with new grease until the rollers are thoroughly covered. Finally, reassemble your trailer hub with the newly greased bearings and mount the hub back on the spindle and axle.
