Remove the lug nuts completely and take off the wheel.

3. Remove Brake Components

Tools Required: Socket set, torque wrench.
Remove the caliper by unscrewing the caliper bolts.
Suspend the caliper using a bungee cord or hang it securely to avoid straining the brake line.
Remove the brake rotor by unscrewing any retaining screws if applicable.

4. Replace Wheel Bearing

Tools Required: Bearing puller, socket set, hammer, torque wrench.
Remove the dust cap from the hub (if present) and take out the retaining nut.
Use a bearing puller to extract the old wheel bearing from the hub.
Clean the hub area thoroughly to remove any debris or old grease.
Install the new wheel bearing by pressing it into place, ensuring it is seated properly.

5. Reassemble Components

Reinstall the brake rotor and secure it with retaining screws.
Reattach the brake caliper and tighten the bolts to the manufacturer’s specified torque.
Mount the wheel back onto the hub and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Lower the vehicle from the jack stands and remove the jack.
