Steps
- Remove the wheel
With the car still on the ground, loosen the lug nuts, then jack it up and remove them along with the wheel.

Pull the drum off, use vise-grips to unhook the springs, pry the adjuster lever off with a screwdriver, then remove the pin holding the shoes and set everything aside.
- Remove the old hub
Disconnect the ABS sensor if equipped, remove the T50 Torx bolts while holding their nuts with an 18mm wrench, separate the hub from the backing plate, then clean the mating surface with a wire brush.
- Install the new hub
Set the new hub in place, secure its T50 bolts and nuts and torque them to about 44 ft-lb, then plug the ABS sensor back in.

Refer to a dedicated drum-brake guide to reassemble the shoes and drum, then torque the lug nuts in a star pattern.
