Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, wheel bearing puller, hammer, and grease.
Ensure the vehicle is on a level surface and secure the vehicle with jack stands after lifting.

2. Remove Wheel

Loosen the lug nuts using the lug wrench while the vehicle is on the ground.
Jack up the vehicle and securely place it on jack stands.
Remove the lug nuts and take off the wheel.

3. Remove Brake Components

Remove the caliper by disconnecting the caliper bolts using a socket. Support the caliper with a bungee cord to avoid stress on the brake line.
Remove the brake rotor by taking out the retaining screws (if applicable) and sliding it off.

4. Remove Wheel Bearing Assembly

Remove the hub assembly by unscrewing the wheel bearing retaining bolts. This may require a socket and ratchet.
Use a wheel bearing puller to extract the wheel bearing from the hub if necessary.

5. Install New Wheel Bearing

Clean the hub assembly and apply a thin layer of grease to the new wheel bearing.
Press the new wheel bearing into the hub assembly using the wheel bearing puller or a suitable tool.
Reinstall the hub assembly by tightening the retaining bolts to the manufacturer’s torque specification.

6. Reassemble Brake Components

Reinstall the brake rotor and secure it with the retaining screws.
Reattach the brake caliper and tighten the caliper bolts.

7. Reinstall Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specification.
