You can Select Your Vehicle to check if 42410-0E020 fits your vehicle.

The following procedure applies to 2WD models only; for 4WD models, special tools and expertise are required to press the hub and bearing from the rear axle carrier, so this job should be left to a professional shop. However, the axle carrier and hub may be removed and the assembly taken to a dealer service department or other repair shop. The rear hub and bearing assembly is not serviceable; if found to be defective, it must be replaced as a unit. To begin removal, loosen the wheel lug nuts, raise the vehicle, and support it securely on jackstands before removing the wheel. Next, remove the disc from the hub and disconnect the wheel speed sensor electrical connector. Then, remove the four hub-to-axle carrier bolts by turning the hub flange to expose each bolt. After that, remove the hub and bearing assembly from its seat, maneuvering it out through the parking brake assembly. For installation, position the hub and bearing assembly on the axle carrier and align the holes in the backing plate before installing the bolts, using a magnet to guide them into position. Once all four bolts are installed, tighten them to the specified torque, then install the disc and caliper, followed by the wheel. Finally, lower the vehicle and tighten the lug nuts to the specified torque.
