I have a EZ Loader trailer with the sure lube system. I replaced all the bearings two years ago and I have another bearing that is slightly rough. I replaced one of the axles when I bought the boat since the tortion axle was bent. The new axle does not have a vent hole for the grease like the old axle does. Does the grease just go inside the axle in that case? The old axle has the weep hole that I can grease the axle until I see fresh grease coming out the weep hole. With the new axle, I just give it a few pumps from the grease gun.
