These hubs layer the bearings with oil as they rotate, developing a much more effective barrier in between the bearings and also water than grease. These hubs have actually the added advantage of being less complicated to service due to the fact that you can drain the oil out without getting rid of the whole center. However they aren’t recommended for trailers that sit for prolonged periods of time since the oil can settle on the reduced half of the bearings, permitting water to enter into the top portion of the center assembly. There are 2 primary ways to reconstruct your trailer’s hubs, as well as the very best technique is typically to get a total axle center that features all the bearings as well as seals currently pushed in. You can find them at many trailer supply parts counters as well as online. When eliminating a hub’s dirt cap, you’ll require to raise the trailer so that it can rotate easily. Then, utilizing a small 2×4 or similar item, extra pound the dirt cap in position so it’s set equally. This will make it much easier to eliminate the dust cap without ripping it off.
