Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent electrical issues.

2. Remove Wheel

Loosen lug nuts using a socket wrench.
Raise the vehicle with a jack and secure with jack stands.
Remove the lug nuts and take off the wheel.

3. Access the Wheel Bearing

Remove the brake caliper by unscrewing the caliper bolts; support it with a bungee cord or similar to avoid strain on the brake line.
Detach the brake rotor by removing any retaining screws or brackets.

4. Replace Wheel Bearing

Remove the hub assembly by unscrewing the bolts securing it to the knuckle.
Disconnect any sensors or wiring harnesses attached to the hub.
Press out the old wheel bearing using a bearing puller or hydraulic press (if applicable).
Press in the new wheel bearing ensuring it is seated properly.

5. Reassemble Components

Reattach the hub assembly and secure it with the specified torque (typically 30-50 ft-lbs, refer to manufacturer specifications).
Reinstall the brake rotor and caliper.
Mount the wheel back onto the hub and hand-tighten the lug nuts.

6. Final Checks

Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (usually around 80-100 ft-lbs).
Reconnect the battery.
