Solution

1. Preparation

Tools Required: Socket set, torque wrench, wheel chocks, jack and jack stands, bearing puller kit, hammer, and grease.
Raise the vehicle using a jack and secure it on jack stands.
Remove the wheel using a socket set.

2. Remove Brake Components

Sub-steps:
1. Remove the brake caliper bolts using the socket set.
2. Carefully hang the caliper using a bungee cord to avoid stress on the brake line.
3. Remove the brake rotor by unscrewing any retaining screws and sliding it off the hub.

3. Remove Old Wheel Bearing

Sub-steps:
1. Remove the dust cap from the center of the hub using a flathead screwdriver.
2. Unscrew the axle nut using a socket and breaker bar.
3. Use a bearing puller kit to extract the old wheel bearing from the hub assembly.
4. Clean the hub surface with a rag to remove any debris.

4. Install New Wheel Bearing

Sub-steps:
1. Apply a thin layer of grease to the new bearing and the hub surface.
2. Position the new wheel bearing into the hub using the bearing puller to press it in evenly.
3. Reinstall the axle nut and tighten it to the manufacturer's torque specification (typically around 150 ft-lbs).
4. Replace the dust cap by pressing it into place.

5. Reassemble Brake Components

Sub-steps:
1. Reinstall the brake rotor and secure it with retaining screws.
2. Reattach the brake caliper and tighten the bolts to the specified torque (usually around 80 ft-lbs).

6. Reinstall Wheel and Lower Vehicle

Sub-steps:
1. Place the wheel back onto the hub and hand-tighten the lug nuts.
2. Lower the vehicle back to the ground and torque the lug nuts to the manufacturer's specification (typically around 76 ft-lbs).
