Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts.
Raise the vehicle with a jack and secure it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Access the Wheel Bearing

Remove the brake caliper by unscrewing the caliper bolts (typically 14mm or 17mm).
Support the caliper with a bungee cord or hang it so that it doesn't strain the brake line.
Remove the brake rotor by unscrewing any retaining screws if present.

4. Remove the Hub Assembly

Locate the hub assembly and remove the axle nut using a socket (usually 32mm).
Disconnect any ABS sensor wiring if applicable.
Remove the bolts securing the hub assembly to the steering knuckle (typically 12mm or 15mm).
Gently tap the hub assembly with a hammer to release it from the knuckle.

5. Replace Wheel Bearing

Press the old wheel bearing out of the hub assembly using a hydraulic press.
Clean the hub assembly and inspect for any damage.
Press the new wheel bearing into the hub assembly, ensuring it is seated properly.

6. Reassemble

Reattach the hub assembly to the steering knuckle, securing it with the bolts.
Reinstall the axle nut and torque it to manufacturer specifications (usually around 159 Nm or 117 lb-ft).
Reattach the brake rotor and caliper, ensuring all bolts are tightened to spec.
Reinstall the wheel and lug nuts, tightening them in a crisscross pattern to manufacturer torque specifications (usually around 140 Nm or 103 lb-ft).

7. Final Steps

Reconnect the negative battery terminal.
Lower the vehicle off the jack stands.
