Clean the hub assembly and inspect for any scoring or damage.
Install the new wheel bearing carefully, ensuring it is seated properly.

6. Reassemble the Components

Reattach the wheel hub assembly to the spindle and torque the bolts to manufacturer specifications.
Reinstall the brake rotor and caliper, ensuring everything is aligned correctly.
Reinstall the axle nut and torque to specifications.

7. Reattach the Wheel

Place the wheel back on and tighten the lug nuts in a crisscross pattern to the specified torque.
Lower the vehicle back to the ground and reconnect the negative battery terminal.
