Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, wheel bearing puller.
Ensure the vehicle is on a flat surface and the engine is off.
Disconnect the battery to avoid any electrical issues during repair.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Remove Brake Components

Remove the brake caliper by unscrewing the caliper bolts using a socket.
Carefully hang the caliper using a bungee cord or a wire to avoid straining the brake line.
Remove the brake rotor by unscrewing any retaining screws or brackets.

4. Remove Old Wheel Bearing

Remove the hub assembly by unscrewing the bolts that secure it to the knuckle.
Use a wheel bearing puller to extract the old wheel bearing from the hub.
Clean the hub area to prepare for the new bearing installation.

5. Install New Wheel Bearing

Apply a thin layer of grease to the new wheel bearing.
Press the new wheel bearing into the hub using a bearing installer tool or appropriate method.
Reattach the hub assembly to the knuckle and torque the bolts to the manufacturer’s specifications (typically around 100 Nm).

6. Reassemble Brake Components and Wheel

Reinstall the brake rotor and secure it with retaining screws.
Reattach the brake caliper and torque the caliper bolts to specifications (usually around 30 Nm).
Reinstall the wheel, hand-tighten the lug nuts, then lower the vehicle and torque the lug nuts to manufacturer specifications (typically 120 Nm).

7. Final Checks

Reconnect the battery.
Check wheel rotation for smoothness and noise before driving.
