Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, bearing puller, and hammer.
Ensure the vehicle is on a flat surface and the parking brake is engaged.

2. Remove Wheel and Brake Components

Loosen the lug nuts slightly while the wheel is still on the ground.
Jack up the vehicle and secure it on jack stands.
Remove the wheel completely.
Remove the brake caliper and bracket using the appropriate socket size.
- Tip: Hang the caliper using wire to avoid straining the brake line.
Remove the brake rotor by unscrewing any screws or pulling it off if it’s stuck.

3. Remove the Hub Assembly

Remove any dust caps covering the hub assembly.
Use a socket to remove the central hub nut (torque specifications may vary, typically around 200 Nm).
Use a bearing puller to carefully extract the hub assembly from the knuckle.
Inspect the hub for any damage or excessive wear.

4. Install New Wheel Bearing

Clean the hub and knuckle area thoroughly.
Press the new wheel bearing into the hub using a bearing press or suitable tool.
- Note: Ensure the bearing is seated correctly and flush with the hub.
Reinstall the hub assembly into the knuckle, ensuring proper alignment.

5. Reassemble Brake Components and Wheel

Reinstall the central hub nut and tighten to the manufacturer’s specifications.
Reattach the brake rotor and caliper, ensuring all bolts are torqued to specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specification (usually around 120 Nm).

6. Final Checks

Reinstall dust caps if removed.
Double-check all components for tightness and proper installation.
