How is torquing and back-off used to set wheel bearings?
Always rotate or oscillate the wheel while torquing the adjusting nut to ensure that the rollers are fully seated against the cone large rib. 2. Back off the adjusting nut one full turn or until it’s loose. 3. This is where you actually establish end play. Torque the adjusting nut to 50 lbf-ft while rotating the wheel hub assembly. 4.
Always follow wheel torque recommendations. Excessive or inadequate wheel torque can lead to failure of the wheel mounting system and loss of a wheel. Do not remove the outer bearing once it has been installed on the spindle. Removing it could cause the seal to become misaligned and lead to a seal failure or loss of a wheel.
