Modern wheel bearing assemblies are precision-engineered parts which are subjected to tremendous loads while driving. Despite their strength and durability, they are vulnerable to certain forces which may occur during service. This makes setting the proper preload during installation a critical step. Learn more about wheel bearing preload in this BCA HUB video.

Do the front hubs on a 2011 Xterra 4x4 require preload from the axle nut? Or is the torque spec for the axle nut just to keep the axle tight? Could I theoretically run 4x4 hubs on a 2wd without issues?

Good questions! Our BCA WE61172 hub assembly for the 2011 Nissan Xterra 4x4 model is designed with a “rolled closure”, which sets the preload on the bearing from the factory. The Nissan factory torque spec for the axle nut of 101 ft-lbs is to properly retain the axle in the splined hub, not to set the bearing preload. Our BCA WE61213 hub assembly for the 2WD model also features a rolled closure design which sets the bearing preload, and since there is not axle nut, there is no torque spec needed. We do not recommend the use of a part on a vehicle it is not spec’d for, like swapping the 4x4 part in place of the 2WD part. The mounting dimensions and bolt pattern may be the same, however for safety reasons we cannot recommend interchanging the parts. In this case we offer the coverage for both 4WD and RWD at similar cost and availability to accommodate both models. Thanks!
