The rear hub and wheel bearing assembly is sealed-for-life and must be replaced as a unit. To begin removal, loosen the wheel lug nuts, raise the rear of the vehicle, and support it securely on jackstands while blocking the front wheels to prevent rolling. Remove the wheel and pull the brake drum off the hub, addressing any difficulties encountered. Using a no. 55 Torx bit, remove the four hub-to-trailing arm bolts by turning the hub flange to expose each bolt, saving the upper rear bolt for last due to limited clearance with the parking brake strut. Carefully remove the hub and bearing assembly, maneuvering it out through the brake assembly, and temporarily reinstall two bolts through the brake backing plate into the trailing arm to avoid hanging the brake assembly by the hydraulic line. For installation, position the hub and bearing assembly on the trailing arm, aligning the holes in the backing plate, and install the bolts starting with the upper rear bolt, using a magnet to assist in guiding them into position. After all four bolts are installed, tighten them to the specified torque, then install the brake drum and wheel, lower the vehicle, and tighten the wheel lug nuts to the specified torque.
