Trailer axle nuts don't have a torque rating as you don't want to run them down super tight. The trick is to tighten the nut till there's no play in the hub in and out with the wheel installed and then use the cotter pin to hold the nut in place. This allows the hub to seat properly without creating too much friction that would cause damage to the bearing/hub.

That really depends on the material of your rim and the diameter of your wheel studs. If you have a steel wheel with a 1/2 inch stud you would use 90-120 ft/lbs. Steel with 9/16 inch stud 120-140 ft/lbs. Aluminum with 1/2 inch stud 90-100 ft/lbs.…

The UFP H-1377 correlates to a Dexter #84 spindle, which is for a 3,500 pound axle. This will utilize an inner bearing #L68149 and an outer bearing #L44649. As this is being used on a boat trailer, I highly suggest going with the etrailer.com…

The nut on the spindle should be tightened until snug, with no side-to-side play in the hub and then backed off slightly, about maybe a 1/8 of a turn. If the spindle uses a castle nut and cotter pin or tang nut, tighten the nut finger tight until it…
