Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is on a flat surface, and the engine is off.
Disconnect the battery to avoid electrical issues.

2. Remove Wheel

Use a lug wrench to loosen the wheel lug nuts.
Lift the vehicle and remove the lug nuts completely.
Take off the wheel and set it aside.

3. Access Wheel Bearing

Remove the brake caliper by unbolting it from the mounting bracket (use a socket set).
Secure the caliper with a bungee cord to avoid stress on the brake line.
Remove the brake rotor by unscrewing any retaining screws or bolts.

4. Remove Wheel Bearing

Remove the hub assembly by unscrewing the axle nut with a torque wrench.
Disconnect any brake line brackets or sensors that may obstruct access.
Use a bearing puller to carefully extract the old wheel bearing from the hub assembly.

5. Install New Wheel Bearing

Clean the hub assembly and inspect for any damage.
Apply a small amount of grease to the new wheel bearing.
Press the new wheel bearing into the hub assembly using a bearing press.
Reattach the hub assembly, ensuring it is seated correctly.

6. Reassemble Components

Reinstall the brake rotor and secure it with screws.
Reattach the brake caliper and tighten bolts to manufacturer specifications.
Replace the wheel and hand-tighten the lug nuts.

7. Lower Vehicle and Torque Lug Nuts

Lower the vehicle from the jack stands.
Tighten the lug nuts to the manufacturer’s specified torque value.
