How do you change a rear wheel bearing on a Nissan Frontier 4 wheel drive?

To change a rear wheel bearing on a Nissan Frontier 4WD, start by lifting the vehicle and removing the rear wheel. Next, remove the brake caliper and rotor, then detach the axle shaft and any components obstructing access to the bearing. Use a bearing puller to remove the old bearing from the hub, clean the area, and press in the new bearing, ensuring it's properly seated. Reassemble by reversing the disassembly steps, making sure to torque all bolts to the manufacturer's specifications.
