Solution

1. Preparation

Gather tools and parts needed for the job.
Ensure the vehicle is on a flat surface and secure with wheel chocks.
Disconnect the battery to prevent any electrical issues during the repair.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is still on the ground.
Elevate the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Remove Brake Components

Remove the brake caliper and bracket using a socket set.
Suspend the caliper (do not let it dangle) using a bungee cord or similar.
Remove the brake rotor by sliding it off the hub.

4. Remove Wheel Hub Assembly

Remove the axle nut with a socket and breaker bar.
Detach the wheel hub from the control arm and any other attachment points.
Carefully extract the wheel bearing from the hub assembly if it is serviceable separately.

5. Install New Wheel Bearings

Clean the area where the new bearing will be installed.
Press the new bearing into the hub assembly using a bearing press. Ensure it is seated fully.
Reassemble the wheel hub to the control arm and secure with bolts to manufacturer torque specifications.

6. Reassemble Brake Components and Wheel

Reinstall the brake rotor and caliper bracket.
Reattach the brake caliper ensuring it is secured properly.
Mount the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications.
