Carefully remove the old wheel bearing from the hub with a bearing puller if necessary.

5. Install the New Wheel Bearing

Clean the hub assembly and spindle area thoroughly.
Install the new wheel bearing into the hub assembly.
Reattach the hub assembly to the spindle and secure it with the retaining bolts, ensuring they are torqued to the manufacturer’s specifications.

6. Reassemble Brake Components

Reinstall the brake rotor and caliper.
Tighten the caliper mounting bolts to the specified torque.

7. Reinstall the Wheel

Place the wheel back on the hub.
