Solution

1. Preparation

Gather tools and parts needed for the repair.
Tools Required: Socket set, torque wrench, hammer, bearing puller, impact wrench (optional), and a wheel chock.
Safety Warnings: Ensure the vehicle is on a flat surface and securely supported with jack stands before proceeding.

2. Remove Wheel

Loosen lug nuts on the affected wheel while the vehicle is still on the ground.
Lift the vehicle and securely place it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Remove Brake Components

Remove the brake caliper by unscrewing the caliper bolts.
Secure the caliper to the suspension with a wire or bungee cord (do not let it hang by the brake line).
Remove the brake rotor by unscrewing any retaining screws and sliding it off the hub.

4. Remove Hub Assembly

Remove the axle nut using a socket and impact wrench if available.
Disconnect any sensors or clips attached to the hub assembly.
Use a bearing puller to extract the hub from the knuckle. If necessary, tap lightly with a hammer to loosen.

5. Install New Wheel Bearing

Clean the hub assembly area of any debris or old grease.
Install the new wheel bearing into the hub assembly, ensuring it is seated properly.
Reinstall the hub assembly back onto the knuckle, securing it with the axle nut to the manufacturer’s specified torque (typically around 250 Nm or 184 lb-ft).

6. Reassemble Components

Reinstall the brake rotor and secure it with screws.
Reattach the brake caliper and tighten the caliper bolts to the manufacturer’s specifications.
Reinstall the wheel, tightening the lug nuts in a crisscross pattern to the correct torque (usually around 120 Nm or 88 lb-ft).
