- Spin the hub to check for roughness or noise.
- If damaged, proceed to replace.
Remove the brake caliper and rotor:
- Unbolt the caliper and hang it securely without stressing the brake line.
- Remove the rotor by unscrewing any retaining screws if applicable.
Replace the wheel bearing:
- Use a bearing puller for removal.
- Install the new bearing, ensuring it is properly seated.
- Reassemble the rotor and caliper.

3. Inspect and Adjust Serpentine Belt

Check the belt tensioner:
