Tight axles?

First thing is are the Green Bearings pressed on all the way ? When I install screw in studs in the axles I torque the bolts to 55 ft lbs with red lock tight on them and no lock washers, also torque the axle flanges down in a cross pattern just like lug nuts some times if you just tighten one then another if cocks the bearing a little and it binds up so the rear is tight. Shortly after that the bearings burn up and the rear leaks gear oil.
