How much torque to back off wheel bearings?

While oscillating the wheel, torque the adjusting nut to 200 lbf-ft to fully seat the bearing components. Back off the adjusting nut one full turn or until it is loose. To establish end play, torque the adjusting nut to 50 lbf-ft while rotating the wheel hub assembly. Back off the inner (adjusting) nut the amount indicated in the chart below.

How to set wheel bearings with nut torquing?
