7. Clean and Inspect
Clean the wheel hub and surrounding area thoroughly, removing any old grease or debris. Inspect the hub for any damage or wear that may require additional attention.
8. Install the New Wheel Bearing
Apply a generous amount of grease to the new wheel bearing and carefully press it into place on the hub. Use a bearing puller (optional) to ensure a snug fit.
9. Reassemble Everything
Replace the axle nut and tighten it to the specified torque using a torque wrench. Reattach the rotor and brake caliper. Reconnect the electrical connector to the caliper.
10. Mount the Wheel
Lift the tire onto the wheelbase and carefully align it. Thread the lug nuts onto the bolts and hand-tighten them as much as possible. Lower the vehicle and completely tighten the lug nuts using a torque wrench.
